Regarding my 2020 Honda Odyssey vehicle, there is a manufacturing defect which allows water to infiltrate the rear driver-??s side body panel, where it comes into contact with the control unit for the rear power tailgate (a/k/a power liftgate). Once water infiltrates the control unit, it causes the power tailgate to malfunction. Many consumers have reported that the malfunctions include the tailgate opening and closing without notice and while operating the vehicle, the tailgate failing to open, and the tailgate failing to close. With the control module getting wet and becoming oxidize/faulty that also makes the battery work harder which causes the car not to start, etc.. Consumers are then forced to pay out of pocket for expensive repairs only to have the replacement control unit also prone to future failures caused by further water infiltration. Honda of Tenafly is saying this is not a recall and not covered. [XXX] [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have had 3 Power Tailgate modules fail due to water leaks in the rear panel or window of the vehicle. I have had 2 leaks repaired and two modules replaced within a 6 month period (June '24 and December '24). 6 weeks later (Feb 14, 2024) have had the 3 module fail due to water intrusion following a heavy rain.

It happened twice this month already. Once while driving, the car lost power (as if engine was never turned on), and the gear changed to N so I tried to slow down, then the power came back on, and then I was able to shift to D and continue my trip. Second one happened this morning. It was on auto-shutting idle position and when I put my foot on the accelerator, it completely lost power again (I recently changed the battery and tested in the afternoon and all working properly).

After driving for about a minute, there is a beep and the brake system warning light comes on. Then the dash begins cycling through multiple warning messages - LKAS/ACC/CMBS/RDM - and will not stop. Now the repair shop tells us that the front multipurpose camera ADAS needs to be removed and replaced, and the ADAS calibrated. Including the fee to diagnose the issue, total cost is $2,980. Van has about 56,500 miles. We have already had it towed twice for battery replacement following similar symptoms, and had battery replaced both times. But with the new battery only 3 months old, it became clear the issue was bigger.

Infotainment system - while driving suddenly there is a cracking/ shrieking startling noise and infotainment system goes off shutting down ( network communication lost sign comes on) and the screen goes blank. No camera works. Radio and all electronic display goes off for a couple of minutes. Slowly, it begins to come back to life by itself in a couple of minutes. This happens randomly on and off.

I just started up the car one morning and had multiple sensor warnings. Brought it to the Honda dealership and told it was an internal sensor camera malfunction and wanted $2000+ to fix it. This honestly should be a recall as I-??ve had several other Honda owners complaining about the same thing which is a huge safety concern

The contact owns a 2020 Honda Odyssey. The contact stated while stopped at a traffic signal he was depressing the brake pedal to stop the vehicle, when the signal changed, and as he released the brake pedal, the vehicle was not turning on. The contact placed the vehicle in park (P) and restarted the engine. The contact stated that his vehicle is equipped with the Engine Off-On feature. The contact stated that the Off-On was also hesitating before he needed to place the vehicle into the park to restart. The contact stated no warning light was illuminated. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that a software update needed to be performed. The vehicle was repaired. The contact manually turned the feature off to prevent the failure from recurring. The manufacturer was not informed of the failure. The failure mileage was approximately 51,000.

MY GUAGE CONTROL WENT BLACK (It's the screen behind my steering wheel that tells me how many miles the car as, the odometer and speedometer (now don't know my speed!) and has maintenance info that is missing from my view now too! This is a serious safety issue! It also activates cruise control. They want to charge me $2K to replace it. The car is a 2020 with about 32K miles on it! And charged me a $180 diagnostic fee. Incidentally, the radio screen went black a few days later, but when I pressed the brightness button, it came back on. BTW, there is a little stick in front of the screen (maybe for the clock?) and it just spins and spins. Maybe that is simply broken and the brightness is turned down all the way? Though they stated the guage control needs to be replaced entirely. There is not a safety recall on this presently for my VIN and no software updates.

The navigation/ radio / rear view camera just resets multiple times while driving, sometimes it happens more frequently than other days. Message that comes up is: Network Communication Lost. Researched online and tried to resolve via software update but seems to made it worse. Reluctant to take to the dealer as warranty has expired and more importantly, blogs show that the issues have never been resolved even after dealer. Wiring harness replacement didn-??t resolve.

After any kind of weather event that produces water (rain, morning dew, snow melt), the car battery is dead the next morning. It jump starts the following day and will be drive normal until it sits overnight and the dew settles back in. There has been evidence of water leakage from the rear cargo door and the power door does not function. The only way to open the door is by removing the plastic cover and utilizing the mechanical lever on the inside of the door. The problem is a daily occurrence with dew and other water events. We have not gone to any automated carwashes, strictly handwash the car. No warning lights have been produced.

+ What component or system failed or malfunctioned, and is it available for inspection upon request? The front camera, which plays a crucial role in the functioning of the Lane Keep Assist System (LKAS), Adaptive Cruise Control (ACC), Collision Avoidance system, and Auto High Beam, malfunctioned. This camera is integral to these systems. +How was your safety or the safety of others put at risk" The malfunction of the front camera caused critical systems like LKAS, ACC, Collision Avoidance, and Auto High Beam to operate unpredictably. This compromised vehicle control, leading to unintended lane departures, unsafe following distances, and potential collision risks. The Auto High Beam system also failed to adjust correctly, creating visibility hazards for both myself and other drivers. +Has the problem been reproduced or confirmed by a dealer or independent service center" The issue has been confirmed by a dealer, front camera malfunctioned and need to be replaced for $2000.

My 2020 Honda Odyssey is exhibiting problems with the infotainment system. The system will reboot randomly, disabling all functionality of the rear back-up camera, the audio system, the clock, and all other associated features of the "infotainment" system. The screen will display "NETWORK CONNECTION LOST" and "MOST NET OFF" prior to unprompted reboot. System will reboot continuously following failure. Issue is ongoing for the past few months. This issue is the exact issue covered by the NHTSA Campaign Number: 20V439000. Possibly covered under 20V440000. Other 2020 Honda Odyssey vehicles are covered by this recall, however my VIN was not covered. I called Honda, and was not assisted in the slightest with the issue. I am requesting my VIN be added to the recall list, and/or Honda be penalized for improperly identifying vehicles with the affected issue. As it can prevent the rearview camera image from displaying, this vehicle fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 101, "Control and Displays" and 111, "Rearview Mirrors."

This model has had a recall of the wire being to short and having faulty connections. I have replaced the wires module now 5 times. The last time it got replaced after a couple of months the screen on the car has gone blank and now they tell me the whole computer needs to be replaced. No LCD and no backup screen. This is absolutely ridiculous. Anything that can be done this car seems to be a electrical disaster.

The multicamera display unit is defective. It operates several systems and cause multiple warning issues. I believe the design is flawed. In addition to the warnings, both the display for driving information ( speed, rpm, temp, etc.) go blank and the AV unit (radio, entertainment, etc) shuts off too.

- Arlington, TX, USA

On multiple occasions, after stopping the vehicle (for example at a red light), the engine would stop and not restart. After several minutes of frantically trying to restart the vehicle in dangerous situations (stopped in the middle of traffic and nearly rear ended multiple times), the vehicle would eventually start the engine. Bottom line - when stopping at a stop sign or red light, the vehicle turns off the engine and does not restart properly - placing all occupants in a dangerous situation.
