2020 HONDA ODYSSEY Complaints

All warning lights came on for Adaptive Cruise Control, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, and Lane Keeping Assistance.Based on my research, it seems the forward facing camera has failed. The vehicle only has 37,000 miles on it and it is only 5 years old.

I was driving with family to a family trip up to the mountains to enjoy the snow when at a rest area I noticed the odyssey just had a slight delay to turning on before continuing the trip. No lights no signs of anything going wrong. As we continued our trip back onto the freeway on a curvy road and night time the odyssey didn’t want to shift gears wouldn’t speed up for freeway traffic. Immediately started pulling over. The odyssey would make like jerking movements decided to call the tow truck and it quickly escalated to draining the battery. After being at the tow facility for one night it completely didn’t want to even turn on next day. Put a new battery and still drains the battery. I took it to Honda service to run a diagnostic and they come back saying the engine is seized. No lights no signs didn’t see this coming with only 87,000 miles. With a black screen displaying electrical issue at times.

The Infotainment system started blanking out and restarting while driving. This issue has started about 1 year ago to this date. it has occured on multiple occassions, We have brought it to Honda to get it repaired under warranty but they refused. The refusal was due to the fact that they could not "duplicate" the issue regardless of having Video Proof of the issue. The second issue is the Multipurpose camera Malfuncition. My vehicle is no longer under warranty and now I have to shell out $800 USD to fix this issue. All the lights have popped up on the Dash. Both issue have not been adressed by Honda, they refuse to fix the issue with countless other electrical problems that this van has aquired over the short lifespan of this vehicle.

The windshield camera went out. I am now unable to use cruise control auto lights auto breaking.

Complete infotainment system loss and screen blackouts Repeated “Network connection lost” errors Inoperative reverse camera and parking assist systems Ongoing 12V battery drainage due to system faults My Honda dealer has diagnosed the problem as a defective floor wire harness and advised that the entire harness kit must be replaced at an estimated cost of approximately $7,000. While I greatly appreciate the 80% goodwill coverage already offered, the remaining $1,400 out-of-pocket expense is still a significant hardship — particularly since this is a known and documented defect affecting vehicle safety systems. This issue directly impacts the federally mandated rear visibility system (FMVSS 111), rendering the reverse camera and related safety functions inoperative. As such, this is not simply a convenience or infotainment problem, but a critical safety concern. Honda is charging $7000 to fix it and now it says it’s the floor harness kit. They are only covering 80%. I’m required to pay 1400 even though this is a known problem with this vehicle and it’s been occurring since I have owned the vehicle due to multiple visits to the dealership for a resolution, thousands of dollars being spent trying to figure out what it was, we already replaced the head unit and Head unit harness, multiple sensors on the doors, which were not even necessary because the battery was draining from the head unit and now I have no camera and my car is crashing and shutting off and Honda is refusing to escalate

In the past six months the Honda "auto-start" feature has caused my vehicle not to restart while stopped at an intersection. Honda needs to immediately recall all Gen 5 vehicles that use the auto-start feature and permanently disable (or give an option to disable) this useless, safety-affecting "feature". Thank you.

At 67,000 miles the transmission was lurching when shifting in 4th gear. Took it to Honda dealership who found code p0736 stored in TCM. Transmission fluid flushed January 2024 by same dealer. No warning lights ever appeared. Body shop said this requires a new transmission at $10k+

All of the warning lights shows up on the dash board. Honda told me it’s related to a bad Multi purpose camera. None of the safety features or cruise control will work until the camera is fixed.

The Infotainment system continually goes blank, while driving leaving the backup camera disabled and without navigation. I returned the van a week after purchase and did not get it back for a month. Despite the recall was never completed. It has been back to the dealer 6 times for the same issue with no improvement. Currently the problem still exist and the dealer WILL NOT HONOR the uncompleted RECALL ISSUE. The dealer insists the recall was completed yet the original issue was never resolved and is saying I will need to cover all costs.

Front camera goes bad and all the driving safety indicator lights go on. I have been reading so many problems with this. Owners complaining. They want over $2000 to replace My car is over the warranty time limit.
