2017 Acura MDX Complaint Log

When stopping for traffic or at a light and accelerating for take off the car has a delay. It does nothing. It’s a 2sec delay that will be deadly to someone.

The contact owns a 2017 Acura MDX. The contact received notification of NHTSA Campaign Number: 23V751000 (Engine and Engine Cooling) however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

All lights lit up on dashboard with no previous sounds, knocking, or issues. Upon getting the vehicle towed, the dealership said that the CAM Shaft and sensor needs to be replaced. Which is approximately a 4K dollar repair. Upon further inspection. The dealership showed me a copy of a 2018 notice where this was a known issue with a specific code of C0369 where it states that there should be no repairs but only replacment of the complete unit and that the machining of this part is know to have substandard machining spec issues which will cause the shaft to erode. This vehicle only has 67,589 miles on it. (which is out of warranty by 6800 miles.) All of the information that I have investigated states that the only way a CAM shaft goes bad is insufficient lubrication, improper break-in, reusing old/worn components, mechanical interferences, and inferior hardware/hardware not torqued to spec. I beleive this issue needs to be further investigated especially since there is also the new recall which states the crank shaft rod bearing was also failing due to the original machining was out of spec. In addidtion, if this was a known issue withthe CAM Shaft since 2018, why was I not notified and why is this not a recall? The dealership currently has 3 other cars in its service area with the same known issue. Of note, this vehicle was running fine when it was parked and upon starting the car and going approximately 5 mile per hour, all warning lights lit up and said to place the car in park. No other prior warnings or issues to speak of other than stalling when stopped at a red light.

The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

The contact owns a 2017 Acura MDX equipped with Les Schwab Tires, Tire Line: Back Country Touring, Tire Size: 245/50/R20, DOT Number: UP76 DRW. The contact stated that while making a left turn, the front passenger’s side tire rolled over a plastic lane divider. The contact then heard air being released from the tire and immediately pulled over into a parking lot. The contact discovered side wall separation on the front passenger’s side tire and pulled into gas station to replace the tire with the spare. Upon investigation, the contact discovered NHTSA Campaign Number: 21T002000 (Tires) which the contact linked to the failure. The manufacturer was notified of the failure and the contact was informed that the tire size was not included in the recall. The tire was not replaced. The vehicle and tire failure mileages were not provided.

In October I noticed my engine knocking. It has always made a ticking sound so how long it might have knocked before we noticed I don’t know however in October it was clearly noticeable. The first thing I did was check my oil level and it was full. Over the several days it became more noticeable and one morning while driving my check engine light came on and the vehicle lost most(maybe 80%) of it’s power although it did continue running and I managed to make it home and immediately scheduled an appointment with Pecheles Honda to have it looked at. When I started the car the next morning the engine light was off and I drove it to the Honda dealership where I was told I would need a new engine. We regularly had the oil changed using synthetic oil and it never burned one drop of oil so I didn’t have any idea how or why it could have happened because it is very common for issues like this to occur due to low engine oil. Last week I learned of a recall on multiple Honda and Acura vehicles the same year and model as mine due to faulty rod bearings with symptoms exactly like I experienced only to find out that mine is not included in the recall. Right now it is sitting in my yard because I don’t have $10,000 to get the motor replaced. The Honda service manager and their best mechanic were at a loss at how the motor could have went so pre maturely. Something faulty had to have been put in that motor because I took great care of that car and never drove it hard. Before this car we had a 2003 Honda Pilot we owned for nearly 15 years with 300,000 miles on it that never had one issue the whole time we had it and this issue should not happen to 6 year old Acura’s. I wanted to document this issue and hope anyone else going through the same misfortune with these vehicles does the same.

In October the car had 46,000 miles and suddenly the car stopped because there was a transmission problem and we went to the dealer, they said it was an update the software problem, this is considered is not safe for me and my family because the car suddenly stopped in the middle of the road. What if I was going 60 mph on the highway and they car suddenly stopped and caused an accident, and someone was hurt. I don't think it is an update problem. This morning I went to the dealer to talk about it, and they refused to do anything, and we are just reporting and if in the future it happens again then what are we supposed to do if we're on the middle of the highway.

Ive brought my MDX to the dealership service department 6 times for this issue, my car has been with the service department this last time since Nov 28th consecutively. In September I brought it in because my car would shift to park when the auto start/stop engaged, I would have to hit the brakes, shift back in to drive before I could take off. I was told there were 2 recalls that we remedied at that time. I brought my car back in a couple weeks later because the issue was persisting, I also started to get transmission and blind spot monitoring system alerts in those 2 weeks. I was told by the service department that the recall update wasn't "completed" when I brought it the previous time. The shift to park still was not fixed. At the 3rd time to the service department they replaced my starter. After this was done the issues with the car got worse, the car would give me transmission alerts, emission system alerts, power brake, blind spot, etc. & the "D" for drive on the dash would blink. Park would also blink. On the 4th trip they replaced my shifter assembly. After this the issues with the car further worsened and I would get all of the previously mentioned alerts, then my car would shift to neutral and another alert would pop up saying "pull over and park when safe to do so". Thankfully I was never on the interstate when this happened. I have to coast until I can pull off the road. After turning the car off then back on I was still not able to shift in to gear. I had the car towed to Acura, this (5th trip) time they replaced my transmission computer module. The car did the same thing the day after I picked it up. I had it towed back to them again, this latest trip they replaced my powertrain computer module, it did not fix the issue. My MDX has been at the dealership since Nov 28th because they do not know what to attempt to fix next. Im not being given any recourse. There are class-action lawsuits regarding this issue on the internet, so it is not unique to me

The contact owns a 2017 Acura MDX. The contact stated that while driving 70 MPH on an interstate, the engine made an abnormal knocking sound, and the vehicle lost motive power. The check engine warning light was illuminated. The contact was able to pull over to the side of the road. The vehicle was able to restart, but the vehicle failed to exceed 40 MPH, and the engine continued to make an abnormal knocking sound while driving. The contact drove to the nearest independent mechanic, where the contact was informed that the vehicle could not be serviced. The contact stated that the failure occurred while driving out of State, which required the contact to stay in a hotel overnight. The vehicle was towed to the dealer, 500 miles away. The dealer determined that the cylinder #3 crankcase bearing had failed, and the engine needed to be replaced. The manufacturer was notified of the failure and offered to pay for the labor, while the contact would pay for the parts. The vehicle was repaired. The contact related the failure to NHTSA Action Number: PE25008 (Engine). The failure mileage was approximately 64,000.

Had engine failure in August of 2023 and had to replace the engine...in November of 2023 Acura had the Safety Recall due to engine failure. We contacted Acura and was told that our VIN had yet to be recalled and we are still waiting to get reimbursed.

Paint peeling on roof , there is an existing issue regarding mdx pearl white paint peeling but only covered 2014 to 2016. My 2017 pearl white mdx also has the same issue, and a lot more people complaining as well online. I contacted acura and they said that my vin number is not part of the issue . Which is BS. My car has only 31,000 miles eventhough its almost 7 yrs old , it is well kept , garaged suv .

The contact owns a 2017 Acura MDX. The contact stated while driving 25 MPH, the vehicle lost motive power and was jerking. Several unknown warning lights were illuminated. The contact drove the vehicle to a local mechanic to be diagnosed. The mechanic retrieved DTC code: P0369 (Reduced Engine Power). The mechanic replaced the camshaft and the sensors. The manufacturer was not made aware of the failure. The failure mileage was 105,000.

When pulling into traffic the car wants to hesitate almost like stalling when going from 1st to 2nd gear 1st thing in the morning. Almost causing a crash it does it every morning after the car is driving the car for a while it no longer does it. There are no check engine lights on

Driving in rain and multiple systems failed at once without any reason. Car indicates brake systems, lane assistance, power steering, collision mitigation, stability control, etc all indicate problems. No reason for it to all go out at once.

The contact owns a 2017 Acura MDX. The contact stated while at a stop light, the vehicle would not shift out of park. The contact attempted shifting into another gear however, the vehicle would not shift out of park. The vehicle was towed to the dealer however, because the vehicle would not shift out of park, the vehicle was not diagnosed. The vehicle was not repaired. The manufacturer was contacted but no assistance was provided. The failure mileage was 60,000. The VIN was not available.

NHTSA Recal #19V-256 So according to Acura, this vehicle had the tail lights replaced in 2019 but the tail lights broke again in 2023. How do we know if Acura just replaced with same OEM tail lights but didn't fix the problematic tail lights. These lights are not a simple bulb replacement, it is costly in $600/Ea range to replace whole assembly.

Great hesitation, in acceleration, clicking of gears and drive and while putting in reverse also clicking of the years when accelerating

While in a residential area we were accelerating from a slow speed as we were leaving one corner and preparing to enter a second corner. We were in comfort dynamic mode at the time. The car then suddenly lurched forward followed by the drive-train immediately entering into neutral - losing all forward power. We were able to coast across the end of a residential driveway. We then turned the car off, and waited about 15 minutes before restarting the car. At that point everything worked normally with no indication of a continuation of the problem. Although the transmission went into neutral during the incident the shift clearly remained in the drive position. We were very careful about checking to see if we had somehow been at fault - bit this was definitely not driver’s error. We were fortunate on two fronts. Firstly, had an adult or child been in the crosswalk we were approaching at the time it could have ended badly. Secondly, we were at slow speed in modest traffic and had enough momentum to safely coast out of traffic. However, the incident was unsettling and we remain highly cautious about driving the car now. Later that evening we drove the car for about 30 minutes attempting to recreate the incident or see if we noticed anything odd at all about the transmission, shift, or electronics. We did this on a secluded road, using each of the car’s dynamic modes, at varying speeds, and changing acceleration. However, we were not able to recreate the incident. We did not notice anything odd about the car and no warning lights came on. There were also no warning lights leading up to or during the incident. The vehicle is available for inspection if requested. To be fair, we have not yet contacted the dealership. However given the seriousness of this issue and potential danger we felt it was important to report it right away.

While in a residential area we were accelerating from a slow speed as we were leaving one corner and preparing to enter a second corner. The car then suddenly lurched forward followed by the drivetrain immediately entered into neutral - losing all forward power. We were able to coast across the end of a residential driveway. (The owner wasn’t thrilled about that at first but understood after an explanation.) We then turned the car off, ans waited about 15 minutes before restarting the car. At that point everything worked normally with no indication of a continuation of the problem. The car was in the comfort dynamic mode at the time.

While driving at freeway speed, fourth lane from the right, the vehicle became unresponsive to the gas pedal input and started to glide. I managed to get the vehicle to a narrow shoulder on the right before coming to a complete stop. I had one of my grand child in the car seat as a passenger at this time and I was very concerned about stalling in traffic and getting rear ended.

On Friday May 5th, 2023 myson was driving our 2017 Acura MDX in heavy rush hour traffic on Interstate 355 near Homer Glen when suddenly and without warning the transmission failed and caused sudden deacceleration. He drove the car which was going 7 mph and engine revving and starting to clatter to get off the freeway. The check engine light came on. He called and informed me while on the exit ramp. I instructed him to pull into the Gas N Wash filling station at 15930 W 159th and shut the engine off, I left home immediately and upon arrival I looked under the hood for oil leakage or low level and belts broken. When I started the motor a knocking sound caused me to turn it off. This could have caused an accident due to heavy traffic at 70 MPH posted speed limit. The car has been towed to local mechanic shop for diagnosis. My online research indicates a Class Action Suit and countless complaints of similar unsafe operation and transmission failure. We purchased this Vehicle new in 2017 from Rizza Acura, Orland Park, IL and have had regular maintenance performed since purchase date.

at highway speeds, the transmission unexpectedly shifts to neutral with no warning. The only indication is unexpected decrease in speed and accompanying engine rev. My typical driver response is to take foot off accelerator, then put back on again. Engine overrevs then shifts in to gear. I'd estimate it's out of gear for ~ 5 seconds, but hard to say in the heat of the driving moment. This happens 1-2X most highway trips, but not occur at lower speeds (it does not shift very smoothly in lower gears at times, but it's not currently a safety issue). I've taken it to my local dealer (Hendrick Acura, Durham, NC) and contacted Acura Customer Care, and am trying to get a diagnostic scheduled (it's been a process). The behavior started to worsen over the past several months (e.g. the slip to neutral has lengthened in time) but shorter slips have been occurring for a longer time period.

On a 2,000 mile family road trip the car shifted to neutral two times at highway speeds. Fortunately, I didn't lose my power steering or power brakes. The car remained on but I had no power. Then the car jerked, the rpm's dropped to 1,000 and then jumped around a little and the car took off again.

The driver’s seat is loose. It became loose over time. It moves forward and back by about 1/4” during starts and stops. It gets worse each month. There is a recall for the same thing the next model year.

I was on the feeder road of a major freeway in Houston Texas at a stop the brake fully applied. The auto engine idle stop was enabled. When I removed my foot from the brake the engine did not restart. The lights, radio remained on but I was unable to drive my car or change the gear shift. Being on a freeway feeder was a dangerous place to be stalled and had to wait in major traffic for a tow truck to come as the vehicle could not be started or turned off. Completely inoperable. The check engine light was on and oil light. I was towed to a nearby maintenance shop where a p2638 code was listed. After the car was towed the car would restart. Prior to the incident there have been other occasions where the vehicle struggles to restart the engine from the auto idle. However there were no warning lights. Additionally I scheduled service with the dealership the next day and they show an auto idle recall as an item for repair. There is no recall listed on Nhtsa. Additionally I see a class action lawsuit was filed earlier this week for a potential ongoing, long term issue related to this product.

On Tuesday, November 8, 2022 I had my 20 month year old grandson in a rear facing car seat and he wrapped the middle seat seat belt around is neck and was choking and coughing. I was on my way to pick up my other grandson at school about 4 miles from my home and when I arrived at the school I opened the back door on the driver side where he was sitting and to my surprise and fear he had the seatbelt wrapped around his neck. I tried to remove it seatbelt when he was in the carseat and it was too tight there was no give. I yelled for help and a lady in her car helped me. The only resolution was to cut the middle seat belt. He had to be taken to emergency because he had red marks around his neck.

My 2017 Acura MDX has many issues with both the transmission and electrical. It has an issue shifting between gears, makes a loud sound like metal on wash board, then loses power for 3-5 seconds. I went to put the car in drive and it would not go in drive recently. I've now had to replace the transmission at 79,006 miles. The electrical system lights up when driving telling me my electronic parking brake has been engaged and also that there is emission system issues. My daughter was terrified and crying since i had a loss of power at the same time my dash lit up and I had to get across 5 lanes of traffic to the shoulder of road. The towing company had to remove battery cable to get my electric parking break to release. This is a dangerous and scary automobile

Fuel pump (High - pressure & low- pressure) failed which has caused significantly reduced acceleration and caused the engine to stall in mid operation of the vehicle. I (Driver) was the only person in the vehicle and there was no crash. I would say there is high risk of a crash and it is a serious safety hazard. There were no warning lamps, messages or other symptoms of the problem prior to the failure.This vehicle component was checked by an independent service center and got it repaired. Fuel pump & high pressure pump was ordered and replaced on the vehicle. I paid $1977.59 as the total cost for parts and labor plus tax.

The car several times now has stopped in traffic and died after the idle stop was initiated while stopped in traffic. It will not start up for at least 30 seconds to a minute. We were almost rear-ended because we were stuck in the middle of the road. I was told that Canada has issued a recall because of this issue

Traveling on I-49 north at approximately 80 mph without any sign of a problem when suddenly the car began breaking, shifted into neutral, hazards flashing, and every light on my dash lit up (Emission system Failure, Braking Failure, and Transmission Failure). At first I thought it had something to do with the cruise control, so I tried turning that off, which did not help, so I pulled over to the shoulder safely. This really could have been dangerous had there been more traffic because the car could not accelerate. Once on the shoulder I engaged the parking break as the car would not shift into park or any other gear. I turned off the car while I called state police and roadside assistance. After a while I was able to turn the car on and move it to reverse because I was about 30 yards past an entrance ramp that I could go to off the interstate. All lights were still lit up on the dash. It sounded rough. This was a very dangerous situation and Acrua needs to address this. It is currently awaiting evaluation at Acura of Lafayette.

Driving down the freeway cruising around 70 miles per hour when the multiple sensors tripped and car started to slow down to 50 mph. Took the exit and when I came to a stop the car was moving very slow. Had to go over an overpass and it barely made it over. Close to home so drove the car slowly. The car at times would stop moving and took a little time for it to pick up and started moving slowly again. The sensors that showed were the electric parking brake problem, emissions system problem, transmission system problem, blind spot info system problem. Had I not been close to home or no exit near, my car would have kept slowing down on the freeway. Family car and I also had my kids with me.

My car routinely sends a warning alert that there is an approaching object. It happens more frequently, when the temperature is hot, and it happens mostly when I am stopped at a traffic light. Occasionally, the alerts continue as I'm moving, which is really distracting, but even sitting at a traffic light is distracting and creating a safety issue. I listed yesterday's date, but this happens nearly every day that I drive this vehicle.

The auto engine disable function causes the car to stall unexpectedly. The car engine stops, and the car changes from Drive into Neutral. The only way to re-engage the engine is to place into Park and restart the car. Sometimes, it requires more than one attempt. Fortunately, this has only happened while the car has been stopped, but it has happened at several busy intersections, holding up traffic and creating a safety risk for me and others. Reading online, this is a known issue with suggestions to report this to NHTSA to include in the overall tracking. Hoping for a fix before someone crashes into my stalled car. I listed the last known date, but this happens with frequency (about 1x/week).

When applying brakes, irrespective of speed at which I am traveling, I experience a distinct vibration/judder in the front brakes when applying the brakes on my 2017 Acura MDX.

I had the transmission system failure error came on the dash and the car wouldn’t drive to D or reverse then blind spot and adaptive cruise control error propped up

Complete Transmission failure at 77,000 miles. Vehicle lost power at highway speeds causing a dangerous situation and stranded our family 650 miles from home. Had vehicle towed to the nearest acura dealership where I was told the transmission was terminal and needed to be replaced. Three weeks later the dealership has failed to find a transmission and nothing has happened. Acura extended a good faith discount on the repairs 4k down from 9k because it failed just out of warranty.

While driving on the interstate, the engine suddenly lost power and a lot of malfunction indicator lights turned on. Driver was able to pull over without incident. Mechanic reported the engine had failed due to loss of oil pressure. The engine had to be replaced.

The vehicle stalls and loses all power when coming out of auto idle stop. This is a default feature that shuts the engine off when the vehicle stops to create fuel efficiency. But it is creating a terrible safety issue of having vehicles unexpectedly stopped on the roadway. The feature cannot be permanently turned off. Common issue on MDX forums without any real solution from dealership mechanics.

Since 2020 the transmission does not shift properly from second to third gear. The power drops and the car shutters and makes noise like gear teeth are missing. This does not happen every time though. Sometimes multiple days will pass before the problem arises again. There have been a couple of times where I barely avoided a wreck because of the drop in power and underperformance of the transmission.

Copied below is my email to the Piazza Acura dealership. They will not provide a loaner. ________________________ My name is [XXX] and I purchased a new 2017 Acura MDX with AWD and the tech package from your dealership on 27 August 2016. In early April of 2022, the front passenger seat belt of my MDX stopped working. I was asked to come into your dealership to confirm that it was not working, and I did so on 12 April 2022. At that time a new seat belt was ordered, and I was told it would take about a month at most. For your reference, the part number, order reference number, and date of order are included below. · Part number: 04814-TZ5-A00ZA · Order reference number: U3990412 · Date ordered: 12 April 2022 It is now past the one-year anniversary of this safety warranty problem being brought to your dealership’s attention, and the theoretical delivery date keeps getting pushed out. Just today, I called the Parts Department and was told there is a new shipping date of 04 June 2023. Frankly, I don’t believe it and feel like I’m just being strung along. I ask you [XXX], what would you think if you were in my situation? This MDX is my only car, and I have had limited use of it to carry passengers for over a year due to the effective loss of the front passenger seat. Because this is a safety issue, my hands are further tied in that I cannot trade or sell my MDX. It is very strange that this seat belt stopped working, and I have to wonder if it was a design or manufacturing defect. Nevertheless, I have been the only one dealing with the consequences, and I have had to do so for over a year. I am unwilling to continue to do so, and now propose that Piazza Acura treat this like any other extended warranty repair situation and provide me with a comparable late-model MDX loaner free of charge until such time as Piazza Acura and the Honda Corporation can provide me with and install a new, manufacturer-supplied front passenger seat belt.

I was driving on the highway at normal highway speeds of 70MPH when the car lost the ability to accelerate, and I was forced to make an emergency stop on the side of the interstate. With the heavy traffic on the interstate, this scenario could have been catastrophic as there is currently construction and no place to pull over for emergencies. The vehicle was towed to Hubler Acura in Greenwood IN where they performed a diagnostic test and no known issues were found on their diagnostic computer. However, the issue is not happening on a computer at the dealer, the issue occurred on the interstate while traveling 70mph. I have read several message boards where the users have posted similar experiences about losing power when accelerating in their 2017 MDX. The dealerships seem to offer a transmission fluid change or a computer reset as a solution. I have previously had the same acceleration issue and had these two items already completed within the past 90 days and neither issue resolved the problem, which further led to the most recent interstate incident. From my online research, Honda is either unwilling or unable to diagnose this common transmission problem and they need to be held accountable for their inaction. This issue needs to be addressed before it creates a scenario with fatalities.

Sunroof exploded while driving for no reason!

On March 20, 2022, I was on the freeway going 65 miles per hour in the fast lane and my transmission warning light came on and the car went in to Neutral and lost all power on the gas pedal and the car would not move. I could not put it in Park or it would roll backwards so I put on my hazard lights and kept my foot on the brake. I was almost rear ended several times as it was 9:30pm and no lights on the freeway in the area I was at and no place to get out and find a safe spot as my car would have rolled backwards as it would not come out of Neutral and at that spot in the freeway there is only cement walls. I was able to get the Calif. Highway Patrol to get me a tow company that could tow my car after I called 911. AAA which I have said it would be 90 minutes. I would have been killed before that. The tow truck driver had to tow my car to the Hopkins Acura dealership in Fairfield, CA where I had just had it serviced the Thursday and Friday before on March 17 and 18 for the car's 100,000 maintenance work. The Hopkins Acura said they test drove it after the maintenance work which cost me $3500.00 but my speedometer showed they only put 1.5 miles on my car so they did not test drive it far. The dealership said they do not touch the transmission during the big maintenance but this car was driving fine and for this transmission to just stop and freeze is so dangerous. The dealership says they will fix the transmission as they spoke to two different companies they work with but they want me to pay $600.00 of the repair which I do not think is fair.

The rear tail lights stopped working completely due to manufacturing defect of rear tail lights causing electric short circuit by moisture . Defective tail lights Safety recall was performed in August 2021 by Dennisville Acura. The rear tail lights stopped working again due to same issue.Took to the dealer Davis Acura on 17 Feb 2022 to perform the safety recall again and dealer refused to perform the repair to fix the safety recall issue. I want to file a complaint against Honda of NA and Davis Acura of Langhorne for refusing to perform safety recall on a vehicle with safety recall issue.

Purchased used vehicle in 9/2021 and since then we have had 5 incidents with the Idle Stop feature. It seems to shut down the engine and it takes 5 min to restart. The last time it happened was on a busy highway and there was traffic. I stopped because of traffic and when I tried to press gas it completely shut off. The previous times it happened at lights or intersection. After the third time, I made it a point to turn off the idle stop but if you forget you run the risk of the shut down which could cause major accident. I should not have to make sure to turn it off every time. I do have EG Assurance coverage and will be taking it in. My fear is that the idle stop issue does not happen every time and they may say they don’t see any issues. I am hoping something can be done as I have taken it in to Acura dealership and they can’t find anything wrong. Thankfully I do see that there are complaints about this and it’s not that we were “doing something wrong”

This morning I read that you were investigating the automatic braking for certain Honda models. I have had this same thing happen with my 2017 Acura MDX several times over the past few years. I would be driving (not following another car), and my car would suddenly brake and flash "Brake" on the screen, without my doing anything. Both times, I attributed the issue to driving into a bright sun, but I am not sure. It did not cause an accident and it was not a big deal, but the last time (about 3 months ago) I remember braking and being nervous about someone else read ending me...when I tried to accelerate I was unable to do so.

The vehicle put emission system and electronic parking brake warning lights on panel, allowed vehicle to be placed in drive "D", then suddenly switched to a flashing "P," stalled in parking lot, and would not allow the vehicle to be changed to any other gear.

Vehicle has ongoing rough transmission shifting issues. It jerks between gears when accelerating at stop signs or stop lights. I have also received a letter from attorney alleging ongoing transmission issues with this model - 2017 MDX. Car has only 23k miles. I used your website to search for possible recalls and did not see any. However, I wanted to share my experience to hopefully help others or perhaps hope of others reporting same mechanical issue.

Driving East on Interstate 20/59 10 miles East of Meridian, MS November 17, 2021 around 2:00 PM. A lot of trucks on the road. Had speed control set at 69 MPH. Came up behind a semi doing about 65, pulled over to the left lane to go around him. When I got about half way all of a sudden all hell breaks loose. Vehicle goes in into emergency stop with lights flashing all over the dash. Vehicle brakes to around 30 MPH within a couple of hundred feet with semi's and cars beside and behind me. Finally got the vehicle over to the side of the rode without and accident. (A miracle inself). Code DTC P0716. After about an hour of shutdown, started engine and all messages were gone. Took it to the Acura dealer and they, evidently, updated the TCM software. I had not been notified that it needed and update which is negligence on Acura. This incidence could have been a catastrophe with possible deaths. Now my wife is really afraid to drive this vehicle.

i bought new car in 2017 November and around over 2500k miles I heard engine chirping sound and if you're surrounded by wall you can hear it louder. took it to dealership several time but they said it's normal and show me another car to prove to me. Which it did had same sound. Then yrs go by I hear loud clunking sound underneath the car every time I reversed and when switching gear to reverse. also about 1-2 yr owning it I heard clunking sound on steering wheel so when mechanic looked at dealership they said it could have been air bag wires so they secured it and shouldn't have any more problem. on 3rd yr I went back to dealership because I know something is wrong with steering wheel clunking sound when turning low speed to right and felt much tighter to turn. they said one of suspension is problem so they replaced but 2wks later happen again. I was in rush for them to resolve before my 4yr warranty ends but they keep playing around saying initially by experience mechanic when we did test drive he heard the sound and thinks it's steering rack or pinion. so I was relived after yr of back n forth they figured out and tells me to wait for next step. but after 1hr waiting at lobby they told me after lifting car up can't manipulate the sound again so can't fix. I wanted to speak to that mechanic again and the way he looked at me and said sorry I don't know what's wrong with it seem like his been told by higher up to lie bc that day they had corporate person visit and that person refused my claim. I asked to fix steering rack or both and they said we can't bc its costing them money and what if that's not the case. I took it to local mechanic and whenever my vehicle is lifted its hard to find the sound but when on ground you can hear. Then recently I brought up that clunk sound to different mechanic during oil change they found out that my body frame was loose so he tighten the bolts. He said it's rare to have frame loose. after that no more clunking when reversing.
