A recall has been issued on my vehicle since February. It is now almost May and when I call Honda about the recall they tell me that they do not have the solution as of yet.

The contact owns a 2021 Honda Odyssey. The contact stated that while driving at various speeds, the "Passenger-??s Sliding Door Failure" message was displayed on the instrument panel. The contact also stated that the rear passenger-??s side sliding door failed to fully open upon entering or exiting the vehicle. The vehicle was taken to two dealers, Honda of Fort Myers (3550 Colonial Blvd, Fort Myers, FL 33966) and Coconut Point Honda (22240 S Tamiami Trail, Estero, FL 33928) and the contact was provided a diagnostic test fee to determine the cause of the failure, but the contact declined. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The vehicle was not repaired. The failure mileage was approximately 19,000.

All of the safety system and efficiency systems had failures which made us take to our local Honda dealership for evaluation. After the first visit we were told that they could not find the problem, although they saw all of the error messages. The error messages appeared again 3 days later so we took it back to our local Honda dealership. This time one of the service reps had seen that problem before and said it probably was due to water entering the rear trunk circuit board controller and shorting out the connections. This was confirmed by a service tech during the 2nd evaluation. After research this is apparently a common issue. We had to pay approximately $700 to fix the situation because Honda does not have this issue as a recall. We believe this is a clear design error that allows water to enter the circuit board housing. This created a dangerous situation as the head lamps as well as the driver safety features and direction signals intermittenly worked due to the shorted out circuit board.

Upon going to start my vehicle it would not start. I ended up jump starting the car and going to buy a new battery. I replaced the battery even though repair facility stated battery was at 78% and in good state. Two days later I went to start the van again and the battery was again dead. I jumped the car to get it started and have had to continually jump start the car due to no start issue. The alternator is showing a constant 14.3 volt charge when running but the battery continues to die. Has left my family stranded multiple times in the past week. No known cause or fix.

I was driving on I-270 highway in active HOV lane and had to stop because of traffic. The car stopped the engine as it usually does by "Auto Idle Stop" system but failed to start it back when I needed to continue driving. I noticed that the battery light blinked on the dashboard when it tried to re-start the engine. As a result I was in active HOV lane with quickly approaching traffic from behind. We all (me, my wife and 2 kids) were scared. I called 911 immediately for help. This all could end up with a crash and injuries. While calling 911 I was trying to restart the car by pressing the button to turn the car off and on. About 3 attempts failed when a few minutes later the engine started and we continued the drive. This was the worst nightmare to stuck on a highway. Luckily nothing happened but it definitely could. This is a major concern for me.

The VSA modulator has repeatedly failed. When it fails, all of the safety systems report errors - air bags, ABS brakes, high beams, traction control, blind spot detection, parking sensors, etc. Additionally, the power sliding passenger doors and tailgate will not open, even manually. I have taken it into Honda dealerships on 3 separate occasions. On 6/14/21 (vehicle mileage 7,453) they cleared the error codes and reset the system and reported it was fixed. On 2/26/2022 (vehicle mileage 21,077) it happened again and they reported the VSA modulator as defective and replaced it under warranty. On 7/29/2022 (vehicle mileage 26,916) it happened again. This time the dealership disconnected and reconnected the VSA modulator and it decided it was fixed. At the time of the issue I was driving the van at approximately 30 mph on flat streets through my town. I've expressed my concerns that this defect renders the vehicle extremely unsafe. Over the past two weeks I've contacted Honda Corporate repeatedly requesting further repairs or assurances that this error would not occur again and have been passed around to case managers' voice mailboxes and have been unable to speak to anyone about my concerns. While no injury or crash has occurred yet, I am concerned that this if this occurs again, myself or my family could be hurt.

Honda Odyssey 2021 has major safety issues -?" the van starts engine on itself, shuts the engine on itself, tail lights are on when the engine is running, the knob for the lights on the turn signal handle was in OFF position when the van was observed starting, running and shutting engine on itself -?" for no reason. In all occasions key fobs were untouched. Once Honda Odyssey was observed with the engine starting and shutting on itself when both of the key fobs were in 10 miles distance from the vehicle. Brought twice to the dealer, cannot fix it. Contacted Honda on 2/17/22 informed about the problem. Called Honda on 2/21/22 to check on the case, was told that will assign a manager to review this safety concern, but it may take two weeks, possibly two month or maybe more, depending how busy they are. 8 days have passed, no response yet from Honda. I am concerned that it may shut the engine on its own while driving.

The 'infotainment" system turned off stating "network connection lost." The speakers then started making a VERY loud crackling sound that could not be controlled with the volume button. It was very distracting to the driver--sounded like rocks hitting the windshield. When the infotainment system was off, the blindspot monitor and back-up camera stopped functioning. This has happened several times.

2021 Honda odessey lost power while driving 6 times. I ended up taking it to get service and the dealer couldn't replicate the issue in 3 different occasions. Ended up trading the odessey on Thursday for a new one. However the the new 2021 Honda odessey that I bought Thursday 4/8/21 lost power on me today as I was driving.
