Rearview System Braking problems of the 2018 Honda Odyssey

The vehicle previously received a manufacturer dash wiring recall repair. After the recall repair was completed, the vehicle began experiencing intermittent and cascading electrical and communication failures across multiple integrated systems. Affected systems include apple carplay, the dvd system, in-vehicle camera systems, cabinwatch, and repeated “most network unavailable” error messages. These failures occur intermittently and result in multiple systems disabling simultaneously. The vehicle was inspected by a Honda dealership, which confirmed the issue involves wiring within the dash harness. The dealership stated the affected wiring is not sold or serviceable separately and that correction would require replacement of the entire dash harness, but that this portion of the harness is not included in the original recall coverage. Because these systems share common power and communication pathways, failures cascade across multiple modules. When the camera system fails, rear view camera functionality and related warnings are unavailable while backing up, reducing the driver’s ability to detect obstacles, pedestrians, or children behind the vehicle. When cabinwatch is unavailable, the driver is unable to visually monitor children seated in the rear rows while driving, which affects situational awareness and the ability to respond quickly to unsafe conditions inside the vehicle. These failures also impact driver information systems and create intermittent loss of critical visual feedback, increasing driver distraction as systems drop out unexpectedly while the vehicle is in operation. The condition began after the recall repair and appears to be related to or a continuation of the original recall defect. The vehicle remains available for inspection, and the condition has been confirmed by a manufacturer-authorized dealer.

I started the vehicle and it displayed a message on the infotainment system screen that the system had lost power. I believed that this would only affect the radio functionality which I was not concerned about immediately. I placed the vehicle in reverse and I accidentally backed up into a parked car. At no point before the accident did I realize the rear camera did not work and the collision assistance sensors did not function. I believe if the collision avoidance system was working correctly my accident would have been prevented. I have come to depend on the safety features of this vehicle. I know that this is not an issue with my car battery as I recently had a Honda dealer install a new battery prior to this accident and the vehicle started normally.

When coming to a stop, usually in stop / go traffic and at times when coming to a complete stop, the auto-idle stop kicks in, but then immediately shuts the engine down and shifts vehicle into park. Vehicle has to be entirely shut down and restarted to bring the engine back. We have been taking the vehicle to the dealership since we bought it a couple of years ago. Seems to be mostly occurring in warm summer months. Also affects the audio entertainment, all sounds stop. And after the most recent repair by the dealership (replacing the tuner), the display screen will not come on for 10-15 min when first starting the vehicle (including the back-up cam and warnings).

The rear view camera on this car is defective. Honda and the dealership appear to be playing games with customers stating that they will get this dealt with but no eta has been forthcoming the whole of 2022.

The infotainment screen went dark during the trip causing loss of navigation guidance, loss of safety features such as back up camera and rear cross traffic warning. It caused loss of climate control as well as every single option related to and/or activated via infotainment display (wifi hotspot, bluetooth function, navigation, etc. . ).

Backup camera stopped displaying and cross traffic monitor non functional. No warning or impaired function before system failure. All fuses checked ok.
