NHTSA Owner Complaint Log
This page lists owner-reported complaints filed with NHTSA for the 2019 Acura MDX. Complaints are unverified consumer reports submitted to NHTSA and do not by themselves prove a defect or defect rate.
My car has stalled while driving on the highway multiple times now. The first time it happened, it lost power, stopped accelerating, and cycled through multiple warning lights, causing a significant safety risk. I pulled over and it restarted within minutes. I took it to a repair shop and they could not find a problem with it, even with the codes provided. Nothing pointed to a solution. It happened two other times while I was driving my child on a highway where it lost acceleration and then kicked back in. Again, this post, a significant safety risk as always in a fast lane on a highway with my child cars behind me had to hit their brakes to avoid me after this incident. Other times it doesn’t lose power, yet it cycles through warning lights randomly. I took it to the dealer instead of a local shop. They texted me about items that should be fixed per an inspection, including struts and a battery replacement. Complete with a large bill just for diagnostics. Yet, nothing was found having to do with the main problem at hand. Losing power while driving. . My battery is less than six months old. I had it tested and it is fine. My vin is not listed in the recall, but, all of the symptoms match the other recalls of the same year make and model.
While driving at 25 miles an hour on a smooth curving road out of a housing area my wife who was driving and my grand daughter in the front passenger seat heard a loud boom that sounded like somthing hit the roof. My grand daughter looked into the back passenger area and said she saw a large buldge in the headliner near the back window on the drivers side. My wife continued driving saftly to the nearest parking lot and parked the vehicle, she got out and inspected the roof and found no dammage of any kind. she opened the back window tail gate and saw a large fist size buldge in the headliner near the open area on the drivers side. She had no idea what happened. There were no waring lights or indicators that indicated a problem and she drove home and showed it to me. When I saw it I thought it was a rear window or curtian air bag that tried to deploy but did not break through the headlinner. I have called the dealer and scheduled an appointment to check it out on thur March 26 at 09:00 2026. I verified that there are no indicators or warning lights that indicate a problem. The service department said it should be safe to drive until then.
The contact owns a 2019 Acura MDX. The contact stated while driving at an undisclosed speed and depressing the accelerator pedal, the vehicle failed to accelerate as intended and to exceed 5 MPH. The vehicle was driven to the shoulder of the roadway. The contact stated that several unknown warning lights were illuminated. The vehicle was towed to the dealer, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The contact did not agree with the diagnosis. The contact stated that the failure was a known failure with the vehicle. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 72,692.
UNKNOWN
While driving at highway speed, the vehicle suddenly lost the ability to accelerate. Immediately prior to this, the vehicle was making an abnormal engine noise, which continued until the failure. "Drive" light turned off and the "Neutral" turned on its own. I tried to get it to shift back to "Drive" and it wouldn't. I pulled off to the side of the highway. The engine stalled and the vehicle would not restart. The vehicle was towed from the highway and we were told to have it towed to Acura dealer in the morning. This incident occurred while Recall 23V-751 (engine connecting rod bearing defect) was open and incomplete.
We had the recall repair done on the start/stop feature on our MDX and it seemed to work initially. But recently the feature has caused the vehicle to stall at intersections again as it did before. It’s happened at least 3 times in the last six months with the most recent occurrence being on 1/20/2026. These occurrences happen despite the fact that we try to remember to turn off the feature when we start our trip. Each occurrence has stalled the vehicle at a traffic light in rush hour traffic. It’s very frightening and we are lucky that it hasn’t caused an accident or gotten us shot! We live in Texas (funny but not).
The taillights on this vehicle are defective. I have already had one taillight replaced and now the other side needs to be replaced. These taillights are $300 each for parts only.
I was merging onto the interstate from another interstate when my car suddenly became limp and would not accelerate. I had zero warning there was anything wrong with my car, only 67,150 miles. I had to coast to the side of the road and it wasn't driveable. I was forced to have it towed to Acura to find out it's a rocker arm oil pressure switch that apparently goes out after 60,000-100,000 miles. Without warning, this is a huge safety issue. There should be a backup switch and notification to get it to a dealer. I had 3 kids in the car, traveling 65 when it suddenly decided to stop accelerating. ZERO warning. It was terrifying. I could have been hit by another car on the interstate, with 3 kids in the car, zero warning to cars behind me that my speed went from 65 to almost nothing instantly. I've always owned Honda cars and this is the first vehicle I've ever had this happen in. Dealership confirmed it was a faulty switch, nothing to do with low oil, dirty oil and I have that in writing. Acrua/Honda should figure out how to alert users that there is an issue before there is an issue. Or put this on the maintenance schedule because I'm terrified to drive this car now. Or how will I know if it's ready to do it again. Again, some type of backup switch that works for a bit until you can get it to dealer. I had to be towed to dealer. Kids had to be picked up. All things that could have been avoided if Honda did a better job.
Front windshield camera went bad due to overheating. When malfunction it gives multiple warning lights, everything that has to deal with front windshield camera does not work. Ive hearing multiple and multiple stories online and in person that they too is affected by camera malfunctioning. There needs to be a recall on it as it is affecting way too many people. My car is a 2019 with ONLY 47000 miles pretty much still new. Parts plus labor and camera calibration is $2200
Since the purchase of my Acura MDX 2019, the following problems have been reported to the dealership and to Honda Manufacturing Inc. without any resolution. The dealer shop has replaced recall parts, but the problems persist and have not gone away. The vehicle stalls and stops working while driving. The engine makes knocking/rattling noises upon becoming disabled while driving.The engine would randomly not start when turning it on. When car becomes disabled the dashboard lights up warning lights displaying messages intermittently of the following problems: Anti-Lock Brake System Problem (ABS), Vehicle Stability Assist (VSA), Hill Start Assist, Trailer Stability Assist, Collision Mitigation System, Road Departure Mitigation System, Adaptive Cruise Control, Lane Keeping Assist, Brake System, Brake Hold System, Electric Parking Brake, SH-AWD, Keyless Start System and Power Steering System (EPS) Problems, while displaying ACC and LWKS codes. Additionally, the vehicle runs improperly and shuts down completely making the window, doors, etc, inoperable while passengers are inside locking me in and my entire family for long periods of time. A few times has left me either myself or with my children and dog inside. The only place where I take my car for services is where I purchased it (Chevy Chase Acura). The issues noted are the same reported by the recalls I have received, and I have not taken it somewhere else because of that reason. Nobody can fix them as the problems are manufacturing issues that even Acura/Honda cannot repair. This safety defect can kill or seriously injure me, my passengers, and other drivers on the road. As noted in one of the many recalls the fuel pump defect can cause the vehicle to stop in the highway and could prevent an engine from starting or cause a vehicle to stall while being driven, it potentially increases the risk of a fire, crash, or injury. My car continues to have these issues and nobody is helping me. Please help!
Turned on my car last night and many lights appeared including emissions system problem, electronic brake problem and SH-AWD malfunctioning. All the lights came on at once. According to forums, this is happening with many Acura RDX, MDX models and manufacturer does not have a clear way to repair or resolve the issue. My car has had all the routine maintenance and is scheduled for the 2 recalls to be repaired next week.
Multi purpose camera stops working while in use causing safety features to stop working. Has almost caused a serious accident.Acura is stating it is not an issue they feel obligated to fix.
The transfer case is blown, with metal debris collected in it. This has caused the all wheel drive to not work because the transfer case is not sending any power to the rear wheels. The car dashboard doesn't register that that transfer case isn't working, so it it thinks the all wheel drive is working, when it isn't. A bad transfer case can cause the car to lose control or traction when it needs to use the all wheel drive system or completely stop while on a highway because it can lead to damage to other parts of the power train. This has been confirmed by an independent service center. There are no warning lights telling me the transfer case is blown or that there are any issues with the power train. The only sympton I noticed was a high pitched sound when driving. These symptoms first appeared about 3 weeks ago.
The front camera mounted near the rear view mirror stopped working which caused several systems to fail. Acura was slow to respond and was not able to complete the repair because the camera was backordered for several months.
We just got into the vehicle and was driving down the road when the sunroof exploded. Nothing hit it and nobody was around us when it happened. I about went off the road. Didn't know what happened. Very scary that a sunroof can just explode on its own with nothing hitting it.
Constant errors in dash. Cruise control fails while driving. Auto braking no longer works. Warning of other vehicles in blind spots does not work anymore. Many error in dash display regarding the camera and lkas are displayed.
My car has failed to restart while sitting at red lights. The engine complete shut down. This has happened twice now since I have owned the vehicle. The first occurrence was around March 2024 and the most recent occurrence was 09/2025. Very dangerous situation both times and I had my child in the car.
The drivers seat is lose and can be felt and heard making noise when driving, even at low speeds. It shifts back and forth upon acceleration and deceleration. Ive had a mechanic look at it and determine it is in fact shifting around while driving, which is extremely unsafe. Upon further research found that many othet Acura/Honda users have had the same issue especially in the MDX model mentioned here. Its even been reported by dealers in brand new, still in the showroom MDX. It is clearly not a wear and tear issue and needs a recall to be addressed.
Camera is failing - reportedly due to a bad internal ground-wire. Acura is charging $900 for the part and $1600 for the installation and calibration of a new unit !! Also - the unit is a black color, and located right behind the windshield, so bakes itself to death. Acura should be using white colors inside the space, limit the un-used volume, and recalling the units (or at least providing a low-cost unit) to allow simple replacement and improve safety. Such an important AND EXPENSIVE part should not be failing so often. The MXers.org web site has hundreds of posts about this item. ALSO - the parts should be pre-calibrated! Acura wants several hundred $$ to calibrate it and 4 days to do it. NHTSA should NOT be requiring ADAS technology if it is so fragile and expensive to fix/replace, as in the long-run owners will not maintain it (e..g $2,400 repair bills for a small camera part nad 5 minute change).

I was driving at about 65mph on the NJ Turnpike at 7:45pm on 8/28/25 when suddenly the accelerator pedal was non-responsive over a period of about 3-5 seconds. The RPMs dropped (engine did not stall) and the vehicle speed began to diminish. No warning lights showed and the dashboard remained lit as usual. The road was wet from a recent downpour. This was a very scary moment as my vehicle was surrounded by trucks. I further depressed the accelerator pedal and was able to regain control of the vehicle. This is the one and only time this happened with this vehicle as far as I am aware. I have scheduled to bring it to Acura service next week regarding this issue. A Google search has revealed several class action lawsuits regarding this issue.
The windshield camera suddenly failed one day while driving and it ended up disabling all the driver assist systems including the emergency braking, lane keep assist, forward collision, auto high beam, cruise control etc. Over the next few weeks the system kept randomly working and failing during driving every few hours or minutes. The discussion forums are filled with people complaining about the same issue with ALL Honda and Acura vehicles starting 2013 where they camera suddenly fails and then start working intermittently until it eventually fails. It seems Honda is using the same defective camera across all it's Honda and Acura models which is a big safety hazard and they refuse to acknowledge the issue.
The front camera responsible for forward collision warning and lanekeep has failed. The camera has part number 36160-TYR-A02. It failed on it's own but it could have been alot worse if it failed before a collision occurred. The dealer and independent repair shop said it was the camera code U3000-49 and this was an out of pocket repair. The symptoms include having these error messages on the gauge cluster. Adaptive Cruise, Lane Keep Assist, Road Departure, Collision Mitigation, and Auto High Beam Problem. At first it would intermittently show up but then after a while those errors would not go away.
Vehicle is getting errors for Emssions controls, parking brake, and sh-awd system faults all at the same time. Car will still function normally and codes will go off and come back intermittently. Also while reading the codes it will get a U3006-16 code for low voltage on the ecm. Confirmed battery is good under load test and alternator is charging at 14.2 volts.
My 2019 Acura MDX which was owned for less than two years, broke down due to a transmission failure. The vehicle had an open recall (one of many recent) delayed by Acura for months, which research shows can cause engine and transmission damage. Acura of Reno denied the recall link and misattributed the failure to “incorrect fluid,” despite admitting the fluid was correct to myself and other businesses. I believe this breakdown was directly related to the open recall and request an investigation into Acura’s handling of these failures. There have been many legal cases against acura regarding this matter previously.
The passenger windshield behind the driver's seat smelled of smoke and exploded the car while driving. This model has had multiple of the same problem with other cars and refused to identify and fix the problem. I have been informed by Acura that it's an out-of-pocket expense and not covered by warranty because it's not yet under recall despite several occurrences.
At only 44,318 miles, my 2019 Acura MDX began showing clear transmission problems in the lower gears — including delayed acceleration, gear slipping, and jerky movement when starting or turning at low speed. These symptoms posed an immediate safety risk, especially when merging into traffic or making turns across oncoming vehicles. I first brought the car to Oakland Acura, which incorrectly diagnosed it as a transfer case issue. Their misdiagnosis delayed the repair process and added unnecessary cost and time. I then had the vehicle evaluated at Acura Concord, where it was correctly diagnosed as transmission failure in the lower gears. An independent, certified mechanic also confirmed the same diagnosis. Despite multiple confirmations of premature transmission failure — and a full maintenance history — American Honda offered only a $900 discount on a $9,600 repair, citing the vehicle being just outside the time warranty (but with low mileage well under 50K). I believe this is a manufacturer defect, not a wear-and-tear issue. Safety Concern: This transmission failure is not just inconvenient — it is dangerous. The vehicle hesitates when accelerating from stops or low speeds, which can lead to accidents at intersections, highway merges, or left turns. The misdiagnosis further delayed identifying and addressing this issue. I am filing this complaint to urge NHTSA to investigate whether this is part of a broader pattern with Acura MDX transmissions, and to help prevent similar risks for other drivers and families.
Vehicle Make/Model/Year: 2019 Acura MDX Component Affected: Forward Collision Avoidance / Lane Departure / ADAS (Front Camera System) Summary of Issue: I am filing this complaint regarding a recurring and dangerous issue involving the front windshield-mounted camera on our 2019 Acura MDX. After purchasing this vehicle and driving approximately 5500 miles in Las Vegas, multiple critical safety warnings began appearing on the dashboard, including: •“Collision Mitigation System Problem” •“Road Departure Mitigation System Problem” •“Lane Keeping Assist Problem” •“Adaptive Cruise Control Problem” These warnings occur continuosly. The warning lights won’t turn off, resulting in the complete shutdown of essential Advanced Driver Assistance Systems (ADAS). Safety Concerns: This camera-related failure disables major safety features designed to prevent accidents. The driver is left without automatic emergency braking, lane keeping, or adaptive cruise control. This is especially dangerous at highway speeds. Acura has not issued a recall, despite the widespread nature of this problem and documented cases in other hot-weather regions. Service Experience: We purchased the vehicle used from a Cadillac dealership. The issue began approximately 3 months after purchase. A mechanic confirmed that the front camera system is likely malfunctioning due to heat exposure—a known problem with this model. Why I’m Reporting: I believe this is a safety defect that should prompt investigation. Acura appears to have issued Technical Service Bulletins (TSBs) but has not taken action to proactively notify owners or issue a recall. This defect compromises driver and passenger safety and puts others at risk.
The contact owns a 2019 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 contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was not made aware of the issue. The manufacturer was made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.
while driving, mdx loose power especially on freeway speed. engine start jerking.
My 2019 Acura MDX with 100K miles stalled on the road with several alerts on the dashboard and went into Parking mode with no further movement. Had several alerts stating Transmission failure, Blind Spot monitoring failure, Auto break system failure and vehicle stalled on the road. Had similar issues previously where the steering jammed and vehicle was stalled on the signal, took it to Acura dealer and they had to fix some circuit / reset the circuit board. Was ok for few months and last week the car stalled with Parking sign on. Towed the car to the Dealer service center, they diagnosed and identified there is a failure with transmission. They quoted around 10000 dollars for replace new and 7000 for used transmission. This is huge money, hence called Acura customer care for any review/support but they claimed this issue is not in their current recalls or claims, so cannot support. had to pay out of the pocket. Per google there seemed to be a lawsuit with Transmission failures with Acura 2019 mdx vehicle. Acura customer relations is asking to get into the law suit group and Acura as such cannot help the customers with these problems. Had Lexus for several years with no issues and very upset/annoyed with these type of repairs within 100K / 5year old.
Electric Parking Brake Problem and Emission System Problem lights came on spontaneously
The headlight assemblies to my vehicle have become defective. The headlight assembly, both right and left, has moisture intrusion within the headlight assembly, creating condensation build-up inside the housing. This issue also caused the headlights to become white and hazy in appearance. I was advised by the dealer that this would lead to failure with the lighting and would have to be replaced. I purchased a certified used vehicle with Tustin Acura in August of 2022 and also purchased an extended warranty for piece of mind. In the 2 1/2 years that I have owned the vehicle, I have added about 25k miles and have always garaged the vehicle. When the issue was reviewed by the dealer, they refused to cover the problem under warranty and requested that I reach out to American Honda for further assistance. I did that but was denied and told the issue was caused by "outside influence," but provided no explanation as to what this meant. To me it felt like I was being blamed for clearly a defective issue. A Google search of this issues revealed to me that this was a common issue with 2019 Acura MDX vehicles. To replace the headlights would be a cost to me of nearly $3,000. it seems almost ridiculous to pay for clearly defective equipment. I fear that my inability to afford this great expense with lead to headlight failure that could result in a collision if this failure were to occur at night.
The contact owned a 2019 Acura MDX. The contact stated that while driving approximately 40 MPH, the vehicle experienced a sudden jolt. The contact immediately depressed the brake pedal and the vehicle erroneously accelerated to a high rate of speed. The contact depressed the brake pedal, shifted to neutral, and to the park position but the vehicle continued to increase speed eventually crashing into several vehicles that were stopped at a red light. The vehicle then crashed into a moving vehicle where it came to a stop. The contact indicated that during the incident four vehicles were crashed into and the vehicle's collision avoidance system did not activate as intended. The contact sustained an injured back which later required medical treatment. A second motorist sustained an undisclosed eye injury. No further information was available. A police report was taken at the scene and the vehicle was towed to the home. The cause of the failure was not yet determined. The vehicle was a total loss. The manufacturer and local dealer were not yet contacted. The failure mileage was 22,229.
Loud clunking noise when steering, possibly the rack and pinion. Control arms and struts have been replaced.
The car is stalling on the highway.that very scary situation the dealer said they don’t have the parts to fix it. Also they said till the check light doesn’t come on they can’t fix it. I don’t know what to do
In front of the red light on the way to work in a morning, I stopped my MDX, then when the red light changed to green, I pressed gas pedal to cross over the street, but unfortunately, my car was pulled backward, and meanwhile, I heard a loud sound of Bang from my mdx. I suspect that the loud sound must be from the gears conflicting in the transmission when automatic transmission shifts. Moreover, the car jerks at around 45 mph speed sometimes. Acura must recall fixing this issue.
We received these recalls more than a year ago and after we called the Acura dealership they told us that there were not enough parts to fix the cars now and that they would give us a call when they had the parts, after two months we called them again and same statement, and same thing for 3 more times with the span of six months. today after more than a year I called again and they are saying no part is available! Since I am worried about safety I don't drive my car out of the city but it seems that Acura has no plan to address these recalls.
Engine failure due Dealership refusal to fix recall items. Engine completely stop working in between drive.

I just read about this new recall on Honda and Acura vehicles. I just wanted to say that I am really mad at Honda and you guys at NHTSA. You just put these issues out there in the media that Honda and Acura have all these safety issues and these are really dangers issues people could loose their lives here , but no one fallows what Honda and Acura are doing. I have 2019 Acura MDX and I got this recall flayer in the mail I late 2023 and the flayer stated that we will be notified by Acura and Honda when the parts are available. And it clearly says that this is a dangerous recall lives could be at stake. Guess what now is November 2024 and I was never notified by any means no flayer no phone calls no email no nothing. Nobody cares . Now this comes out again same issue and what nobody cares again. This is ridiculous someone should be held accountable for putting my kids my family in danger. Like I said my vehicle was recalled in 2023 for this same dangerous issue and no one ever contacted or sent another flayer again. Good thing I called Acura two weeks ago just out of curiosity about the recall for 2023 . They said oh ok will schedule you for Aril of 2025 hahaha. This is crazy it takes two years to fix an issue this dangerous. And guess what they will probably call me in April of 2025 and say they have no parts and that would be able to schedule me for 2026. Yeah that how dese recallls work and no one cares about people and family lives.Thank you Honda Acura and NHTSA.
The contact owns a 2019 Acura MDX. The contact stated that the vehicle shifted to park while driving at an undisclosed speed. The engine and EVAP system warning lights were illuminated. There was a leak from the Evaporative Emission Control (EVAP) system. The vehicle was previously taken to the local dealer for NHTSA Campaign Number: 23V858000 (Fuel System, Gasoline). The vehicle was repaired, but the failure recurred. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 88,000.
There are two open recalls, and I have tried reaching out local dealer as well as Honda email, to get these repaired. However, I have been told that fix is not available. It has a year plus and I worry driving car with these issues ignored by Honda. Thanks.

In February 2024, received a recall for fuel pump module, which can result in prevent engine from starting, cause vehicle to lose driver power, or stall while driving. Can also result in failing emissions inspection. Acura reports that repair is not available until Fall 2024. In October 2024, while at a stoplight, auto idle-stop was engaged, and engine stalled and would not turn on. Vehicle needed to be turned off and then engine started at that time. A previous recall that affected auto idle stop was addressed in May 2023 where engine does not auto restart after entering auto idle stop. In April 2023 Acura provided a software update, however in October 2024 the engine stalled as mentioned above. Additionally, a local emissions test was performed and failed around April 2022, and passed a second time when performed a few weeks later. Even after experiencing symptoms of recall 23V-858, recall has not been able to be addressed. This vehicle was brought into Acura in November 2024 for an another recall (23V-751) and I was told that current unaddressed recall may be available within the following month but could not provide any further assistance. Engine stalling at a stoplight puts my family at risk, as well as others. If engine is stalling at a stoplight, engine may stall at other times, including while driving, increasing risk of accident. Recall has been undressed for almost 10 months.
We have had several recall on this automobile. The 2 outstanding recalls are almost a year old. One is for the fuel pump and the other is the connecting rod bearing. My wife is afraid to drive the car long distances because of this. We would like the dealer to buy the vehicle back if they can't perform the repairs.

Driving down 45 at 70mph. Attempted to accelerate and change lanes. Car lost engine power and was almost rear ended before power was restored. Have been waiting almost a year for recall to be complete. Grubbs Acura called is the other day to have service performed. Made the aware of the symptoms. They tried to have us pay for a diagnostic. Informed them that the symptoms were that of the recall. We believe. The engine may have damage and should be further inspected and or replaced. The informed is that they replaced the connecting rod through the oil pain and did not touch the timing belts. However it’s time for timing belts and other maintenance to occur in the next 5k miles. Feel like the job was rushed and it is a safety hazard.
Engine poweer failure while driving at highway speed. Vehicle could not maintain allowed highway speed (above 45 mph) while moving in fast traffic. First warning indicator appeared after driver noticed loss of power while driving 60 mph. Independent service center confirmed error code p0304, misfiring cylinder. Could not identify problem with spark plug or ignition coil. Technition found engine knocking during diagnostic exam.
