Rearview System Braking problems of the 2020 Honda Odyssey

Rear view screen turns off due to radio not working due to fakra connectors.

When driving in reverse the front screen blacks out.

Over 8 multiple safety warnings turned up on dashboard on many occasions while driving. Also, vehicle fails to issue a code on obd and Honda rep claims they’ve never seen anything like this after showing them video proof of multiple occurrences. I’ve seen many complaints online. My wife drives this vehicle with young children and doesn’t feel safe while driving it because of it stating multiple safety warnings.

When I bought the van used in 2023 at a dealership, they were working on the tailgate of the van. They stated it was a factory default that the module had. They did not go into further detail. I started getting a message on the dash panel that the power tailgate system had a problem. I also got messages stating the thee reverse collision system stopped working, transmission system had problems, the keyless starting system problems. This was happening after a rain occurance. I took it to the Honda dealer, they did not know how to fix this. I took it to my mechanic and he found water is getting thru the roof rack rail gulley, leaking down the back drivers side interior panel on to the tailgate control module. I have to take the van to a body shop, so they can fix the affected area. I have the part my mechanic replaced. It is clearly water damaged. The day he fixed my van, it had rained and malfunctioned again. Right now I have the module hanging in the cargo area, outside of the interior panel, so it does not get wet when it rains.

We bought a used 2020 Honda Odyssey, and a few months after buying this vehicle, the infotainment screen blanked out and the vehicle information screen also blinked out. This occurred at the same time with no warning whatsoever. I just turned on the car, and none of the screens came on. These screens are the ones that show the mph, our mileage, cruise control, etc, and also the screen that shows the back up camera, in car calling, back up alert system. None of that works anymore. We made an appointment to take it to a Honda dealership and a few days later it flickered back on and so we did not keep the appointment. Just a month and a half later, it happened again and this time it has not come back on for over a month. We took it to the dealership and were charged $200 for them to tell us it was something wrong with the Honda computer system and the whole thing would need replaced and we would be charged $1800. This is on a barely 4-year-old vehicle & we did not have the money to replace a defective system. So we have been driving without a mph display. We put our phones up on the dashboard and try a gps mph app, but it is wildly inaccurate, and it is a major safety concern because we have no idea what speed we’re going and we have to guess. This is a car with low mileage and barely 4 years old!! we paid a lot of money for the back up camera, in car calling, and extra features like that specifically for the safety of those features. And now we’re being told that basically they can’t find the problem and we have to pay $1800 for those rather high-priority safety features like knowing how fast you’re going. I also have a newly licensed teenage driver and another who will get her temps in 2 months. I can’t even let them drive our vehicle because they certainly don’t have the experience necessary to drive with no speedometer. We live in a state that doesn’t allow handling a phone in any way. This vehicle helped me comply with that & now I must use a phone to show my mph.
