Hello, I am looking for some advice on my 2021 RDX. I took it through the car wash today like usual, put it in neutral and enjoyed the ride. Next thing I know my dash lights lit up like a Christmas tree and the warnings to contact my dealer just kept cycling through. There was 9 of them in total. Emissions system problem, brake system problem, adaptive cruise control problem, etc. Any idea what could have caused this? Is there anything I can do to resolve this? I called the dealer and they said perhaps too much water got in the intake. They advised me to take it for a drive and park it in the heated garage. So far that has not worked.
With so many systems being affected, my first guess would be a problem with battery voltage. Check the battery voltage, with the engine running, to confirm proper alternator output.
Curious if you have an update on this. I am going through old posts as I had something similar happen on my 2019 RDX. The warnings reset after I start the vehicle though.
