2020 HONDA ODYSSEY Complaints

Start stop system malfunctions during auto stop/restart. Van will stall or fully turn off instead of restart when brake released and accelerator pressed. Problem is intermittent and increasing in frequency. This results in unexpected stalls/stops in traffic, putting driver and passengers (as well as other vehicles) at risk. Message displayed is “Collision mitigation system problem” or the van stops itself and tells the driver to “shift to park”. Van may or may not immediately respond to starting push button. Dealership cannot identify problem, but numerous other customers report similar complaints.

The contact owns a 2020 Honda Odyssey. The contact stated that while driving at 30 MPH, she noticed through her rearview mirror that her vehicle's trunk had caught fire without warning. The contact pulled over and was able to extinguish the fire with her shoe. The contact did not suffer any injuries and a police report was not filed. The vehicle was towed to the dealer where it remained in their possession and had yet to be diagnosed. The manufacturer was notified about the failure. The vehicle had yet to be repaired and remained in the possession of the dealer. The failure mileage was approximately 24,000.

The signal turned Red, as I was braking, the car engine stuttered and car shut off. Startled, push the park button, and pressed the engine start button but no response, pressed again and it started. This happened 6 months before but didn't report it as I thought it was a once off event. 6 months ago, the car was at a red light, the IDLE was ON and when I accelerated cause the light changed GREEN, the car shut off. Get the feeling its due to the IDLE but wanted to report this matter

The “auto engine idle stop” system in my minivan is malfunctioning. This is a safety issue because the engine does not always restart when I take my foot off the brake. I am eventually going to be hit from behind by a driver behind me that assumes my minivan will accelerate from a stop when it is supposed to. Every time the malfunction occurs, the dashboard displays a message “Collision Mitigation System Problem”. However, I have been told by the dealership mechanics that this message is erroneous and that it is displaying because there isn’t a preset error message associated with the auto-engine idle stop malfunction. My minivan was 2 years old when I brought it to the dealership for repair the first time. That was in October-2021 and the dealership is Honda on Grand in Elmhurst, Illinois. I brought the vehicle to them on seven different occasions between October-2021 and now. Even though they were able to reproduce the problem, they say they don’t know how to fix it. So, they made minor repairs each time to different electrical and drive train systems in hopes that the malfunction will cease. After 10 months and 7 attempted repairs, my vehicle is still malfunctioning. The dealership instructed me to contact the corporate level Honda Customer Service Department, which I did on July 8, 2022. I was issued a case number and a customer service representative, Walter, to assist in resolving this problem. After many follow-up phone calls to them, they will not return my call to discuss my vehicle. I recently contacted the Elmhurst, IL dealership and spoke with the service manager, David Abraham, who said he would follow up with Walter. However, I still have not been contacted. I am very concerned for my safety and the safety of my two teenage children who are now driving my vehicle. This will undoubtedly lead to a collision if not repaired.

My 2020 Honda Odyssey the engine stalled while I am driving. It isn’t the first time in part two years. My first complaint to the dealer on 2020, the first time my engine stalled when I was moving to the Parking. The engine stalled and all the lights on on the dashboard with a big bang sound. I restarted the car and my car can drive again. I bought it to the honda dealer at puente hills and they told me stop to use the brake hold system while I am driving. After a few weeks later , I have the Same problem again when I made a right turn. After the turn , my car engine stalled again and I almost got rear end from the car behind me. I needed to restarted my car to drive again. After that I drove to other honda dealer at West Covina to check my car and they was unable to find any problems. They told me to take videos when the happenings again. My car was fine for almost two years. My car engine stalled again while I was driving also with the Big Bang sound and all the light on on the dashboard. But I don’t need to restart my car on this time .because the engine start again after all the lights off from the dashboard . I just need to pass the drive button to move my car. I feel so dangerous. I bought my car honda dealer to check and they told me my throttle have carbon buildup so I paid for them to do it. But I am still feeling unsafe and it’s a unacceptable situation.

Reverse backup camera works only intermittently. Several YouTube videos report the same complaint over many years. Dealership unable to duplicate even though I present them my own video with infotainment center warning “CAMERA SYSTEM FAILURE”.

The contact owns a 2020 Honda Odyssey. The contact received notification of NHTSA Campaign Number: 20V438000 (Back Over Prevention) however, the part to do the recall repair was unavailable. 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 stated that while attempting to shift into reverse(R) in rainy weather, the rearview camera failed to operate as designed. The approximate failure mileage was 14,000. Parts distribution disconnect.

I became aware of a news article and videos of a documented security problem with Hondas where someone can use a device to unlock any Honda made in last 10 years and also remotely start the vehicle without leaving any trace of the intrusion. This poses many obvious security and safety risks to a Honda vehicle owner. Example, someone could gain access to a locked vehicle and steal contents. Or they could enter and hide in the back and attack someone. Or they could unlock the car and use the built in garage door opener to gain access to a home. Or they could even start a car remotely in a garage and cause a fire or carbon monoxide poisoning to people inside the home if the garage door remained closed. I am seeking help to get Honda to address this issue immediately and provide remedy to owners for this defect. https://gizmodo.com/new-key-fob-hack-can-unlock-and-start-hondas-remotely-1849165737

The auto idle stop automatically turns on when the van engine is started. I was stopped at a stop sign while trying to cross a dual lane highway (55 mph speed limit). Was not aware that the auto idle stop had shut off the engine. When I had an opportunity to cross the highway I let of the brake and pressed the accelerator and the engine was attempting to start and felt like we were going to be struck by cross traffic before the engine started and we were able to cross. I am aware that this feature can be turned off. But it has to be turned off each time the vehicle is started. Needs to be a way to permanently disable this feature.

The Honda Idle Stop feature is the issue. My wife drives this car and on at least 20 occasions, the car shut off when she was stopped at a stop light when Idle Stop was enabled. The car shuts off when she tried to accelerate once the traffic light turns green. The car then has to be restarted. This is a safety issue because cars behind us could easily rear-end our vehicle since the stop light has turned green and cars are moving. Honda claims that they cannot replicate the issue but it is clearly a large issue with the Idle Stop feature. It seems as if the vehicle does not have enough power to get the engine back to normal mode and therefore it shuts off. Most of the time that air conditioning is running so perhaps the extra load from that contributes. Regardless, this is something that needs to be fixed quickly.
