2023 Honda Odyssey Complaint Log

I am submitting a formal safety complaint regarding a failure of the power tailgate system on my 2023 Honda Odyssey. The issue involves water intrusion into the liftgate control system, which has resulted in corrosion and subsequent failure of the power tailgate. This malfunction presents both a safety concern and a significant reliability issue, particularly for a vehicle of this age and mileage. What is most concerning is that this does not appear to be an isolated incident. There is a documented history of similar failures in Honda Odyssey vehicles, including prior class action litigation related to tailgate and electrical system defects. Despite this, the issue does not appear to have been adequately addressed or corrected in newer models, including the 2023 version. My vehicle has approximately 30,500 miles and is only slightly outside of the warranty period. I was explicitly assured at the time of purchase that the vehicle was reliable and that the manufacturer would stand behind it. However, I have since been informed that this repair will not be covered, despite the apparent design flaw and known history of the issue. A power tailgate failure is not merely an inconvenience—it can pose safety risks, especially when transporting passengers, children, or cargo. A malfunctioning liftgate can fail to open or close properly, potentially causing injury or limiting access in urgent situations. I respectfully request that NHTSA investigate this matter further, as it appears to be part of a broader pattern affecting Honda Odyssey vehicles. Consumers should not be responsible for costly repairs stemming from known defects that have not been properly resolved. Thank you for your time and attention to this matter. I am happy to provide any additional documentation or details if needed. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Rear camera/center display going black. No alarming when backing up when screen is black. Previous recall 23V431000 did not fix problem

The power tailgate control unit (part #74970-THR-A12) failed on my 2023 Honda Odyssey at approximately 46,000 miles and 3 years of age. The tailgate stopped functioning entirely. Upon removing the interior rear trim panels to diagnose, I discovered the failure was caused by water intrusion into the rear body of the vehicle. Behind the interior panels I found: significant rust on interior sheet metal, green corrosion coating the power tailgate control unit, dried water stains showing pooled standing water that had evaporated over time, and clear evidence of repeated slow water exposure over an extended period — not a single incident. The vehicle has no rear windows that open and no exterior damage that would explain the water source. The symptoms and damage pattern match the class action Dubrosky v. American Honda Motor Co., [XXX] , which alleges defective polyurethane rear body seam sealant in 2018-2021 Honda Odysseys allowing water to leak into the rear driver's side panel and destroy the power tailgate control module. My 2023 exhibits identical symptoms, raising the question whether the same defect extends to later model years. SAFETY RISK: The class action documents that this defect has caused tailgates to open or close unexpectedly while the vehicle is in motion, fail to latch, short-circuit, and in some cases cause fires. Items in the cargo area can fall out during driving, creating road hazards for other vehicles. My tailgate failed completely; I consider myself fortunate it failed closed rather than opening in motion. The damaged components are available for inspection. The vehicle has been inspected and photographed by Pohanka Honda of Salisbury, MD, who confirmed the damage but denied warranty coverage. No independent inspection has occurred. WARNINGS PRIOR TO FAILURE: None. No dashboard warning lamps, messages, or symptoms appeared before the tailgate stopped functioning.

Back up camera display went black and issued error. This error is sporadic. please approve replacement.

Rear lift gate randomly opens and closes automatically while driving and when parked. My kids were in the back seat and there were groceries in the trunk that could have fallen out. Dealership said it's not a recall, and that it is due to a bad weather stripping around the rear window allowing water into the lift gate and damage the controls.

While driving, the vehicle loses power, hesitates, and jerks, then stalls and shuts off without warning, especially in extreme heat and stop-and-go traffic. The failure occurs more frequently when the fuel level drops below approximately half a tank. After stalling, the vehicle will not restart until it cools down for 20–30 minutes, then temporarily operates normally before the issue repeats. Warning symptoms prior to failure include loss of acceleration, hesitation, and engine overheating. A fuel pump–related fault code has been detected. The vehicle has stalled while driving, creating a serious safety risk due to sudden loss of power in traffic. This condition matches NHTSA Recall 23V858000, which states the fuel pump may fail and cause engine stall while driving. The fuel system component believed to be involved is available for inspection upon request. The issue has occurred multiple times and is reproducible under similar conditions.

I reported issues regarding egress failure and children stuck within the back seat of the van, Electronic Dashboard failing while driving, and no start issues amongst others (11709419). Previously the certified dealer stated the issues just could not be reproduced, despite my videos, however, today they stated a Honda admin level director showed and told them the issues are being reported by others, they dont know how to fix it, and I need to come get my car, continue driving it.

My 2023 Honda Odyssey Elite has recurring, intermittent safety-related malfunctions across multiple systems. The most serious issues are: (1) door lock/unlock and rear door opening failures preventing emergency egress (children trapped), (2) intermittent “no-start/no-response” where push-button start does nothing (no click/no crank and sometimes no lights/electrical response), and (3) intermittent dashboard/instrument/electrical abnormalities while driving. I also previously experienced dangerous driver-assist behavior including unintended automatic braking and lane/steering behavior in construction zones. Door/egress: Rear doors sometimes will not open from inside or outside even when the vehicle audibly indicates it unlocked. I have video of my children unable to exit the back seat. This is an emergency egress hazard. No-start/no-response: Multiple events where the vehicle appears electrically dead and will not start, then after waiting ~10–30 minutes it starts without a jump. Stranding hazard. Recent examples: 12/31/2025 – doors would not open initially; after entry, no lights/electrical and start button produced zero response; after ~10–20 minutes it started. 01/05/2026 – while driving, dashboard/instrument display went off; buzzing noise believed HVAC related occurred. 01/05/2026 – after parking at Costco, vehicle again would not start (zero response); after ~30 minutes it started. 01/06/2026 – locking/unlocking malfunction again; rear doors would not open despite audible unlock (video). Repair history: Authorized Honda dealer (Bell Road Honda) previously stated “cannot reproduce,” replaced DVD/recall items and performed a “reset,” but did not diagnose root cause; problems returned worse. Honda Customer Service case opened. Injuries: Prior unintended automatic braking event (reported around 08/29/2023) caused injury (my legs hit dash; child had marks from car seat) and near rear-end collisions. Request: Investigate potential safety defects

The front right sensor goes off randomly. Sometimes all day long for days, then nothing for a week or 2 then back to it. Various lengths of time, usually stressfully long times, with nothing aroundcausing stress and making fucus hard. It started a few months after getting the van. We cleaned it, had the dealer inspect it and no one has ever figured out why we have to live with this blaring warning alarm. The dash says object warning with it and if i close that out nothing stops the alarm but putting it in park which I can't do on the interstate or in pickup line at school

I have a 2023 Honda Odyssey. The engine is making a knocking noise. The oil has just been changed with 5.7 quarts, following the factory specifications, but the knocking is still there. The timing belt tensioner has also been replaced, as well as the high-pressure fuel pump. However, the knocking noise is still present, especially at low speeds.

The vehicle engine failed to restart after being idle for a few minutes in heavy traffic on Southern State Parkway. The vehicle’s Auto idle stop function was being utilized during this time.

I was driving about 15 mph in my neighborhood when my passenger side mirror exploded and flew onto my passenger side door/window. It hit so hard that it left a scratch on the window and on the paint.

The contact owns a 2023 Honda Odyssey. The contact stated that while driving approximately 30 MPH, the vehicle started to lose motive power. The contact stated that the check engine and several other unknown warning lights were illuminated. There was an abnormal metallic grinding sound coming from the engine compartment before the vehicle stalled. The contact was unable to restart the vehicle. The contact stated that a tow truck was called, but the driver was unable to restart the vehicle to shift into neutral(N). A tow truck with a dolly was called, and the vehicle was towed to the dealer. The dealer diagnosed the vehicle and determined that the engine had failed and needed to be replaced. The contact wanted a second opinion and had the vehicle towed to another dealer, who also determined that the engine had failed and needed to be replaced. The vehicle was not yet repaired. The manufacturer was informed of the failure. The failure mileage was approximately 71,000.

The contact owns a 2023 Honda Odyssey. The contact stated that while the vehicle was turned off, the contact pressed the tailgate release button on the tailgate, and the tailgate closed and struck the contact on the back. Medical attention was not needed. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 9,000.

I was driving down the road and all the sudden I hear a loud bang/shatter noise. I look over and see that my passenger side mirror is hanging down and shattered. Didn’t notice any impact or anything when it happened. The mechanism that works the mirror broke. No damage to the plastic casing or nothing.

Engine shut off in traffic after Auto Idle-Stop failed to restart. While stopped at a red light with Auto Idle-Stop active, the engine shut down normally. When I released the brake to proceed, all electrical power dropped—cluster went dark, accessories reset, and the engine did not crank. Vehicle coasted dead across the intersection and required a full key-cycle to restart, exposing my family and surrounding traffic to a collision risk. Component that malfunctioned Dealer diagnostic later the same day showed the 12-V battery-current sensor reporting an internal resistance spike from 3 mΩ (normal) to 25 mΩ (fault), which commands the powertrain ECU to inhibit Idle-Stop restart (“Idle-Stop Inhibit – Large battery internal R” flag). An AGM load test confirmed the battery itself is healthy (958 CCA). Reproducibility / confirmation The stall occurred twice on public roads. At the dealer, the fault could be reproduced in the data list: resistance value jumps whenever the negative-terminal sensor is jostled. Inspection status Vehicle was inspected by the franchised Honda dealer; screenshots of the diagnostic session and the Midtronics load-test slip are available on request. Manufacturer has NOT yet repaired the sensor; dealer demanded an unnecessary battery purchase first. Warning indicators No MIL or warning lamps illuminated before the stall. After the first stall, a brief “Auto Idle-Stop System Problem” message flashed but cleared on restart. Risk Loss of propulsion and power steering in the middle of an active intersection without warning. If this sensor defect is common, any similar 2022-24 Honda minivan/SUV with Auto Idle-Stop could stall in traffic. Component is still installed and available for inspection. Filed report with FTC (report #188697846).

Auto stop/start struggles to start at lights or stopped traffic, rough idles and has already killed 1 battery, replaced under warranty and I'm having to charge my new one already since my car struggles to cold start sometimes! Incredibly stressful having 5 kids and 1car I spent a fortune on so it would last forever and it's a lemon I'm holding my breath doesn't strand us any time I have to break.

The contact owns a 2023 Honda Odyssey. The contact stated while his wife was driving 20 MPH, attempting to make left turn, she noticed the passenger side rear view mirror was shattered. The contact mention some of the glass did get into the vehicle. No injuries were sustained. a dealer was contacted. The vehicle was taken to the dealer, and they informed the contact there was no recall for the passenger side rear view mirror. The vehicle was not repaired for the mirror, however the vehicle is currently being serviced for oil change and tire rotation, and brake fluid flush. The contact was relating the failure to an article that he read online regarding this failure for the years 2020-2022. The manufacturer was notified of the failure and opened a case number. The failure mileage was 33,000.

This is regarding the Collision Mitigation Braking System (CMBS) I will be driving on side streets around town (driving kids to school and daycare) and there will be no vehicle/obstacle near me/ in front of me and my van will flash on the dashboard "brake" and then it slams on the brake. This has happened at least 5-6 times as of todays date 5/20/25. There is no warning or reason for the car to brake like this. I have brought this to the Honda dealer two times now once I realized how serious this was. I was informed that since it isn't throwing a code there is nothing they can do. This is a serious safety risk not only to myself but to my children- this is a van so most people who drive this have small children. The last two incidents i was inches from being rear ended with my children in the car. The time before that I had my family from out of town in my car, that could have been eight people seriously injured or killed for no reason.

MY 2023 Odyssey has 40K miles and the cam shaft bearing is deteriorating and my engine oil is full of shavings. The dealership is acting as if because I did not get my oil changed there, that it somehow isnt their fault and not covered under the warranty. This is an existing recall of these engines and nhtsa is investigating other years etc. Here is a video from the tech [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The rear lift gate malfunctioned, causing my rear lift gate to get scratch from top to bottom because the lift gate would NOT STOP. I have never had issues with manually stopping the lift gate. I pushed the button and let it come up and then used force to stop it and it would not stop. I do CrossFit 5 days a week and find myself to be strong suit, I physically could not stop this lift gate. It broke two of my nails in the process because I was doing everything I could to stop the lift gate. Instead of stopping it kept going scratching up against our basketball hoop because it malfunctioned. what if this was my arm or my leg stuck in between versus an item? What if this was someone's head, including my children's head? it would have decapitated them. The amount of force of this lift gate was insane, there was absolutely no stopping it. I have an issue with this, not safe at all. You should be able to easily stop this back lift gate without that much physical force. Our honda odyssey lift gate malfunctioned and WOULD NOT STOP

Not sure about what component could have triggered but I started seeing smoke and fire from the front hood. I managed to stop and exit the call to call emergency services. The fire aggravated that the whole car was burned. The dealer was notified as well as the Honda but yet to hear back. The claim is also filed with insurance company that they indicated to be getting custody of the vehicle to inspect.

I am [XXX]. I purchased this Honda Odyssey van after it was modified by BraunAbility. They put in an automatic underfloor ramp, and other modifications. When used without these modifications, there are three rows of seating. Passengers go in and out, and the passenger-side sliding door opens with an automatic button. There is a sensor that controls that door. It is never in danger of being hit or disturbed in use by an ambulatory person. However, when it is used with a ramp, the second row of seats is removed and replaced with a passenger-side ramp. The ramp is 30 inches wide. The normal power wheelchair is 26 to 29 inches wide. This leaves only 2 inches MAXIMUM on either side of the ramp for the wheelchair. It is virtually impossible to NOT hit the sensor when going in or out by wheelchair!! I have had this van for about two years. I use it about once every two weeks. Most times I have an assistant driving. I have only used it about 50 times TOTAL, in two years. On [XXX], I had a doctor's appointment. I activated the automatic door and ramp. I rolled up the ramp, and parked in the passenger area. That seat has been removed for the wheelchair. My assistant pushed the button to activate the ramp to go back under-floor. It did so. BUT the sliding door on the passenger side did NOT close at all! Eventually he managed to manually slide the door shut. If I had been driving alone, I would have been stranded right there---at the doctor's office, shopping center, etc., as I do NOT have the strength to manually close that door! This is clearly a danger to disabled people using this modified Honda Odyssey. Honda and BraunAbility should be required to protect and reinforce the sensor area so users will NOT easily damage the sensor with light use of this van! This may also be a clear violation of the ADA, the Americans with Disabilities Act. [XXX], Retired INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving approximately 50 mph, vehicle sunroof glass spontaneously exploded spraying shards of glass in the vehicle. The vehicle was not driven under any bridges, and there were no vehicles within a reasonable distance ahead or behind my vehicle that could have thrown something at the sunroof causing it to break. My safety was put at risk as sharp pieces of glass were sprayed on me, into my clothing, and into the empty child safety seats in the middle row. Upon inspection, the Honda service department denies that this break happened spontaneously and the dealer states that they were able to identify a point of impact on the sunroof as to what caused the glass to break. A photo of said impact has been requested from the service department, but as of this writing has not yet been received. There were not any previous known damages to the sunroof, and there were no warning signs prior to the glass shattering.

Profuse amount of water intrusion and pooling of water in the rear of the vehicle near the tailgate of vehicle during rainstorm. Water not from above, ceiling not wet. Concerns about water causing rust, and electrical damage.

Sitting still at intersection of Florida Avenue by US Post Office back window just shattered. No object found inside car. No indication it was hit by anything. Just spontaneously shattered.

The temperature in the mid-Atlantic has been below freezing for several weeks. Additional all of the roads have been treated for ice. My vehicle’s wiper fluid system will not work in these below freezing temperatures. As a result I have not been able to see out of our windshield that is dirty from the road treatments. We are having to clean the windshield with baby wipes. As soon as the temperature gets into the 40s and 50s, only once in the past few weeks, the wiper fluid system works again.

The present complaint alleges as follows: 1. Honda has a defective design in the Advanced Driver Assistance Systems (ADAS) of all Honda Odysseys, models 2018-2023. 2. Namely, Honda has placed the RADAR behind the large HONDA emblem on the front grille. This causes the radar to give a "RADAR OBSTRUCTED" warning, which disables all Advanced Driver Assistance Systems in the car (Automatic Emergency Braking, Adaptive Cruise Control, Forward Collision Warning). 3. The "RADAR OBSTRUCTED" warning cannot be reset by restarting the vehicle or disconnecting the battery, requiring recalibration of the RADAR at the cost of $800 each time since it takes several hours to do (per Dealership). 4. The official Honda Odyssey Forum online has countless complaints on the same issue without resolution by Honda. 5. Honda has acted in bad-faith towards their customers since this defect impacts the vehicle's advanced safety features for which buyers incur additional expenses, endangering the lives of passengers. 6. Honda has acted in bad-faith towards their customers by designing a system that requires continuous and substantial expenditures without resolution because it is an engineering problem, i.e., the placement of the radar behind the large, thick plastic H emblem obstructs the radar. 7. I hereby ask that the NHTSA investigate this issue and order Honda to offer a solution in the form of a RECALL that permanently addresses the problem.

Dear NHTSA, I am writing to report a serious safety concern with my 2023 Honda Odyssey (VIN: [XXX] ). On [XXX], while driving at 45mph, the front and left side airbags deployed suddenly without any impact or collision. There were no other vehicles involved, and no visible damage to the car was apparent. The only indication was the "SRS Airbag Deployed" sign on the dashboard. Upon inspection by Honda of Leander, minor damage was found at the bottom of the vehicle. However, the insurance inspector (Brian, +1-832-418-4052) confirmed that this minor damage should not have caused the airbags to deploy. The airbags deployed without any impact, and only the side airbags were triggered, suggesting a malfunction similar to the recent recall affecting 2020-2022 Honda models [XXX] ). Honda has issued a recall for over 750,000 vehicles due to a defect in the front passenger seat weight sensor. This malfunction could cause the airbag to deploy unintentionally, even when there is no crash, posing a significant safety risk. The recall affects various models, including the Accord, Civic, CR-V, Pilot, and Odyssey from 2020-2022, as well as several Acura models. Given the potential safety risk this malfunction poses, I urge the NHTSA to investigate this specific incident and consider extending the recall to include 2023 Honda Odyssey models. While my family and I were fortunate to be unharmed, this issue presents a serious threat to others and has resulted in the vehicle being totaled, causing us significant financial loss. I respectfully request appropriate action be taken. Please feel free to reach out to me if you need any further information, including photos and videos. Sincerely,  [XXX] [XXX] , [XXX] Vehicle Information: 2023 Honda Odyssey, VIN: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Radar structed ,blind spot off,brake system light on

Around Dec 2024, the central control screen started blacking out. At first, it would black out and then the screen will come back on randomly. We took the car to Tempe Honda service center, and the technician was able to reproduce the problem, and it's covered under warranty. However, they had to order, but they didn't anticipate that it would be in back order. A couple months later, we checked on the status and found out that it was on back order and there is only one manufacturer, so it could take a few more months. We kept on calling to check on the status, and the anticipated back-fill date kept on pushing out. Finally, the screen went completed black and wouldn't come back around Aug 2025. We called Tempe Honda, and the service manager suggested us to call American Honda Motor. We did, and a case was open with American Honda Motor around 10/17/2025. American Honda Motor has been providing weekly update to us, however the update has been the same, which is that they are waiting for ETA on the release date for the part. We wrote an email back on 11/20/2025 with our concerns around safety due to this defect. They called on 11/26/2025 and suggest us to file a complaint with NHTSA. Our concerns in the email include: 1) it's the central control for a lot of the functions including navigation (which we can't update because the screen is broken, and the warranty period to do so will soon be at an end); 2) It's being used when we back up our car. With the defect screen, the back-up camera is useless. This poses potential danger as we pull out of a busy parking lot, such as at school when we drop off and pick up kids. it's very difficult to back up without the screen especially when there are large vehicles parked next to us; 3) To have customers with an essential part of the car being defective for a year is unacceptable. This problem needs to be fixed ASAP. Thank you!

I have a 2023 Honda Odyssey van. The van has been modified for me to drive from my wheelchair. The steering wheel has been locking up eight times when driving. It won’t out let me go straight or turn left or right. This happens when I come to a stop. It happened twice when driving. The wheelchair modifications company southern mobility said they fixed many times but it still have the steering wheel lock up. Now they are telling me it’s the Honda’s fault. Honda said it’s the van modification fault. Honda said they can look at it for $150 a hour. I am very frustrated and very concerned. I am in a wheelchair, my daughter is in a wheelchair, and I need to take my mom to dr appointments. I feel like my life is in despair l

An engine rod blew a hole in the engine block while traveling on the highway. This resulted in loss of engine power while others traveling at highway speeds around me. Additionally the vehicle was smoking heavily and smelled of burning . The vehicle only had 64000 miles with an adequate maintenance record.

The contact owns a 2023 Honda Odyssey. The contact stated while driving at an undisclosed speed, the engine seized. The contact stated that the failure occurred while she was on the entrance ramp entering the freeway. The contact stated that she repeatedly continued to depress the accelerator pedal, and after several attempts, the engine independently started. The vehicle was driven to the contact's intended destination. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 25,500.

Our auto idle randomly will shut the entire van off. Leaving us stranded without being able to go for 15-30 seconds until we can get It restarted. There has been no warnings or codes thrown Early on it has been unable to reproduce for them when at the dealership It has been to dealership numerous times because it’s a scary safety issue with cars usually behind us honking, yelling, and holding up a finger. They did try update some software the most recent time which was unsuccessful. Now they want to put a new starter and relay and engine valve adjustment. Leaving me with the bill for something that happened in warranty since they can’t replicate it within a few minutes

The contact owns a 2023 Honda Odyssey. The contact stated while driving at 60 MPH and attempting to make a left turn, there was an abnormal clicking noise coming from the vehicle. The contact mentioned the failure would be present when making a left turn when driving at any speed. The vehicle was taken to the same dealer on several occasions where the failure was not determined due to being unable to be replicated. On a most recent occasion, the vehicle was taken back to the same dealer where it was diagnosed that the driver-side strut failed and as a result both the driver and passenger side struts needed replacement. The vehicle was not repaired due to costs. The manufacturer was notified of the failure and informed that the vehicle was out of warranty but offered a discount. The approximate failure mileage was 40,000.

The straps for the car seat do not secure and are easily untightened. The issue is solely with the Nuna Rava car seat and not the vehicle. My 1 year old was completely unstrapped after driving because he was playing with the straps. After investigating I found I could easily untighten the straps with one hand without pushing the button to release the tension on the straps. Food debris got underneath the strap and was preventing the mechanism on the button from keeping tension on the straps, rendering the car seat useless. My wife called the manufacturer twice and left voicemails but has not been contacted back, I searched the internet and found multiple cases of this and the fix. I have videos showcasing this, but they are too large to upload.

While driving 35-40 mph, the car started acting strange, shaking and multiple alerts began appearing. No cars were around me and I was able to get the car over to the shoulder quickly. (Mileage 35,483. Owned car 20 months) Messages appearing: Electric Parking Brake Problem, Adaptive Cruise Control Problem, Road Departure Mitigation System Problem, Collision Mitigation System Problem, Hill Start Assist Problem, Emissions System Problem, Electric Parking Brake Problem, Electric Power Steering Problem, Vehicle Stability Assist Problem, CMBS Problem. I turned car off and on, multiple times, hoping it was a fluke, but car was shaking and messages kept appearing. I called Honda Roadside & car towed to dealership. Was told internal failure of oil pump was the problem. Techline reported Multiple vehicles with same codes and same motor have had the same problem. Replacement of spool valve, valve cover gasket & valve was the fix. This may be a future recall. Car drives fine now after being repaired!

Shortly after we passed 30,000 miles and our initial warranty expired, our passenger-side sliding door began having problems in which it would get stuck while opening. We would need to turn off the power to the door and manually pull the door shut. This began happening more often as the weather got colder in November to December 2024. At its peak this winter, it would happen multiple times per day, and the door was basically non-functional. We took it to the Honda dealership several times before they were able to determine that the problem was a faulty latch on the sliding door. We had this replaced on March 14, 2025. The door works fine now, but the weather has been warm. We worry that this will happen again to the new latch and to the driver's-side door.

I was pulling into a parking spot with my foot on the brake. My 2023 Odyssey van accelerated instead of braking. There is also supposed to be an auto car warning & braking if you are about to hit a car in front of you. None of this happened! In fact, it crashed into the car in front of me. As soon as it started to accelerate, I released the brake and reapplied the brake as hard as I could. It still hit the car in front of me. It didn't look like there was any damage to their car, but I was very shaken up and now I am worried this will happen again. It happened today, April 18, 2024. My mother was in the car and was as shocked and stressed as I am as the van went from very slow to fast. My body is still shaking. I haven't had it inspected yet. I have an appointment on May 1, 2024, to go to Odonnell Honda. The woman receptionist in the service area said I may have had my foot on the gas. I did not because when I pull into a parking spot, I always have my foot on the brake and go in very slowly. As a brand-new van, I am very alarmed and very nervous it could happen again.

The car appears to power up on its own even after it has been shut off. I have noticed that the car was on even after I turned it off, so I have been even more diligent about making sure it was turned off. One day I turned off the car. About an hour later, I heard the speakers in my car blaring. When I was finally able to reach the car the sound was off and the car was black. I didn't even get a chance to open the door and turn it off. It just shut down on its own. Yesterday, when I went to start my car, there was a message that the battery was low. As if the car had been on for a while. But when I got in the car it wasn't on. This appears to be a known problem from other Odyssey owners. Specifically I am seeing issue with 2018 models. However mine is a 2023 model.

I was driving on the freeway at approx 65mph with no cars around me when the orange light that said brake came on and the car slowed down on its own. Could not override problem for a few seconds.

The contact owns a 2023 Honda Odyssey. The contact stated while driving 70 MPH, the vehicle shuddered and inadvertently downshifted. The vehicle decelerated to 20 MPH, and the transmission made a grinding sound. No warning light was illuminated. The contact pulled over to the side of the road and coasted the vehicle to Walmart. The vehicle was restarted, and the transmission made an abnormally loud sound while shifting into drive(D). The vehicle was towed to the dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 10,000.
