Blind Spot Detection problems of the 2021 Honda Odyssey

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.

After a slight rain, the error of radar obstructed is being displayed. Can’t get this error removed or fixed. After searching more I found out that: 1. Honda has a defective design in the advanced driver assistance systems (adas) of all Honda Odysseys, models 2018-2023. 2. Namely, Honda has placed the radar behind the large Honda emblem on the front grille. This causes the radar to give a "radar obstructed" warning, which disables all advanced driver assistance systems in the car (automatic emergency braking, adaptive cruise control, forward collision warning). 3. The "radar obstructed" warning cannot be reset by restarting the vehicle or disconnecting the battery, requiring recalibration of the radar at the cost of $800 each time since it takes several hours to do (per dealership). 4. The official Honda Odyssey forum online has countless complaints on the same issue without resolution by Honda. 5. Honda has acted in bad-faith towards their customers since this defect impacts the vehicle's advanced safety features for which buyers incur additional expenses, endangering the lives of passengers. 6. Honda has acted in bad-faith towards their customers by designing a system that requires continuous and substantial expenditures without resolution because it is an engineering problem, I. E. , the placement of the radar behind the large, thick plastic h emblem obstructs the radar. 7. I hereby ask that the NHTSA investigate this issue and order Honda to offer a solution in the form of a recall that permanently addresses the problem.

Rear view mirror on the windshield has a factory defect. It falls off and causes hazardous conditions. I backed into a parked and unoccupied vehicle. It was dark, the warning beeper did not sound until I hit the vehicle. The dealership has attempted to fix the issue 3 times, the item is ordered to fix the mirror. I have reported this issue to the nhsta twice. This is my second update after the initial report. The sales manager, bobby, (cell#336-740-4273), says that he is aware that other Honda vehicles have had this problem with the mirror.

Back up sensors stopped working 4 months after purchasing a brand new vehicle. Also the side sensor just randomly lights up when there’s nothing around or the brake light pops up.
