The vehicle's Auto Idle Stop (AIS) malfunctioned. The vehicle stalled and required a complete "shut down" to restart. The vehicle was first in line at a traffic light. The AIS system engaged. When I took my foot off the break to "go" when the light turned green, the car stalled. An error message popped up, indicating that I needed to shift the car into "park". I did so and the car did not start. I attempted to turn the car off several times, while in park and my foot depressing the break pedal. The car would not turn off. After three minutes of attempting to turn off the car and waiting, I was finally able to successfully start the car. I was traveling with my four young children, three of them in child car seats. I was nearly rear ended by one vehicle, despite having my hazard flashers on, because my car stalled at a traffic light when it was green. Two cars drove around me who were also stopped behind me at the traffic light. Another car came up to the traffic light and my vehicle and nearly rear ended me with my four young children in the car. This is the third time that this exact issue has occurred in my car. I brought it to my local Honda dealership on the same day that the issue first occurred. They inspected it but were unable to replicate it. They said they would make note of it but had not heard of such an issue. I had no idea this could be reported on this website. I was never told about this otherwise I would have reported this on the day that each of the two previous incidents occurred. This issue originally occurred the first time approximately 10/2022 and again for the second time approximately 4/2023. It just occurred for the third time today, 7/14/0225.

2021 Odyssey EXL shuts off completely in traffic stop and go conditions. Happened three times in a 2 week period. Twice in city roads at traffic stop light and once in highway when the cars are in stop / go mode due to heavy traffic. Engine switches off completely and puts itself in "P" mode, all light comes on as if in accessory mode, radio switches off, all doors unlocked. To get going, the driver had to press brake pedal and start the car again (via Engine Start /Stop button). This issue started in the car at 43K miles. Never had any issue with mine before that. But it is scary especially the engine switch off in highway and traffic stop light.

2021 Odyssey EXL the Electric parking brake 'issue' warning comes on while driving and collision mitigation warning / lane assist switches off and flashes in console; when this happens the car continues to run but the dashboard warning lights comes up for Parking brake / Collision Warning and or Lane assist. It gets cleared after I turn on/off the car couple of times and drive for approximately 5 miles. Those features had to be turned on manually, once the car is in parked mode, again. The issue started in the car at around 48K miles. Never had any issue with it before that.

The contact owns a 2021 Honda Odyssey. The contact stated while at a stop light and depressing the brake pedal, the engine turned off; however, once the accelerator pedal was depressed, the Auto START/STOP failed to operate as intended. The contact turned off and restarted the vehicle and the vehicle started to work as intended. No warning light was illuminated. The vehicle was not taken to a dealer or independent mechanic to be diagnosed. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 32,000.

Tailgate would not work (electronically or manually) Other Odyssey owners have had similar problems, some included tailgate opening on its own There were no problems until it just wouldn-??t open one day Dealer replaced module for $700+

It started that all the sensor in our car started to go off. We were told we had a bad battery, even thought we had replaced it new just last year. Once we had the battery checked and alternator. The sensors started to act up again, out tail gate started to malfunction. Wouldn-??t automatically close. A few weeks ago driving down the road the tail gate opened and the anti theft system started going off while the car was running and still going. Come to find out there is a water leak in the rear that has gotten into the rear fuse box and has cause substantial corrosion. The latch to the tail gate is broken. Honda is telling us our extended warranty doesn-??t cover any of this, even though it is common knowledge, that the water leak is a known problem from 2018-2021. We just found out a few days ago.

Car has completely shut off when the auto start/stop engaged after coming to a stop at a red light/stop sign on multiple occasions. Everything shut completely off, no radio, lights, etc. Had to push the start button multiple times to turn the car back on. Please investigate as I have read of this happening to many other people with 0 solution from Honda. This is a defect and should be recalled/fixed.

On 1/31/25 our rear tailgate automatically opened upon parking the car in our garage. Later that day, the tailgate would no operate properly and had to be manually opened. The key fob was functional and could operate all other doors in the car, except the tail gate. Later that day, while the car was parked in our garage, the tailgate started operating by itself, without pressing any buttons on the remote control key fob. It would open and close by itself and repeat the entire sequence over and over again. Upon turning on the car, the display identified a Power Tailgate Problem. The problem was reproduced by the Olathe Kansas Honda dealership. We took it to the dealership today and they diagnosed the problem, stating it is a Gate Control Unit failure (error code P1378 and P1379). Dealer confirmed what we experienced. We documented the safety problem via video. We were able to temporarily fix the issue by disconnecting the car battery overnight and reconnecting it the following morning. Safety concerns - This is a concerning issue as the tail gate could open by itself while driving, and/or could open by itself when you have the car parked in public, allowing theft of any items left inside. It could also open while someone is driving along a parking lot and cause an accident. There was no warning light prior to the malfunction of the tail gate control unit. We have found online that there may be a class action lawsuit regarding this issue.

On 28-Dec-2024 I noticed the power tailgate stopped working on my 2021 Honda Odyssey. I tried to press the power tailgate button on the key fob, the button on the driver's side control panel, and the button on the tailgate itself, but none of them works. I did some research online and found out it's a common problem in 2018 to 2021 models and the cause was the failed Power Tailgate Control Unit due to water leakage through the cracks on the vehicle body. I opened mine and found there was water in the control unit box which might have caused short on the circuit board. I bought a new control unit a week later and it fixed the issue.

Drive side rear power door stopped working. Upon using handl to opperate as usual the door stopped only a few inches open. A gentle shove got it open and opperational. The next day it did the same thing this time refuding to eithe ropen completely or re-latch. My children were in the car with me on the way to school and the door could not be opened to let them out or closed to safely proceed on our route. We began diagnositcs and found that the door continued to be problematic; opening just enough to be unlatched but nor going further, opening only half way and locking in place, or openeing completely then refusing to close... the door being in manual mode or power mode makes no differnece. after complelty disasembling the door/panel to check calbles and motor, checking fuses etc we put it all back to gether and suddenly it worked fin for about a dozen tries. HOWEVER the passanger side rear door (perviously untouched) suddenly developed the same problem. Now both doors will not function in either power or manual mode and I am waiting on the dealership to look into possible computer issues.

After the PGM-FI update was put into our car, the engine cuts out entirely while at stop lights and will not wake back up. The Honda dealership is saying that there is nothing they can do.

1. While I was driving on the freeway, my radio turned off and my car put itself into NEUTRAL! I was able to safely pull over and put it back in drive. Note: This incident happened after 2 months of weird electrical things happening to the car, such as the radio turning on after the car had been turned off, car not starting, sliding doors losing power when they are halfway closed, coming to a stop and putting the car in park then the car completely loses all power/interior lights, the car turning off while stopped at a light and more... 2. Had there been more traffic I would have been in major danger. I could have easily been rear-ended or hit someone in the process of trying to get off of the freeway. It could have caused a multiple car collision. Grateful my children were not in the car at the time of the incident. 3. The car has been inspected by Spreen Honda multiple times and by an independent Honda mechanic. Spreen Honda has not been able to reproduce the problem. They won't do anything besides hook it up to the computer, and since there are no codes present "there is nothing they can do". The independent mechanic said they'd never seen anything like this. When I reported the incident to Honda America, they recommended I should continue taking the car to the dealership, which makes no sense as the dealership does not actually attempt to diagnose the problem if there is no code. 4. The manufacturer has not inspected the vehicle. When I reported this to Honda America they encouraged me to continue working with the dealership service department only. They don't take information from 3rd party service providers. This is completely unacceptable. 5. Right before the car shifted to neutral, the radio turned off and the dash lit up orange.

1. Incident: I was driving and stopped at a red light, took my foot off of the brake and the car completely died, leaving me stranded at the intersection. The car started back up after 4 minutes. Note: This incident happened after 2 months of weird electrical things happening to the car, such as the radio turning on after the car had been turned off, car not starting, sliding doors losing power when they are halfway closed, coming to a stop and putting the car in park then the car completely loses all power/interior lights, and more... 2. My safety was put at risk by having a non-functioning car in the middle of the road. Someone could have rear-ended me. Also, it was over 100 degrees outside which added to the panic I was feeling. 3. The car has been inspected by Spreen Honda multiple times and by an independent Honda mechanic. Spreen Honda has not been able to reproduce the problem. They won't do anything besides hook it up to the computer, and since there are no codes present "there is nothing they can do". The independent mechanic said they'd never seen anything like this. 4. The manufacturer has not inspected the vehicle. When I reported this to Honda America they encouraged me to continue working with the dealer. This is completely unacceptable. 5. Right before the power went out the dash lit up with every warning lamp for maybe 5 seconds.
