Our 2010 Georgetown 374 did the same thing on the ride home from the dealer, the check engine light came on all the way home too, four ride home. Then the LED brake lights stuck on when everything was off. Nothing we did would shut them off. Being tired, we just disconnected all the batteries, because the truck battery apparently wouldn't shut the brake lights off, so we then disconnected the coach batteries and this worked. Ok long story short next day go out hook if all back up and everything was back to working, cameras, fans, mirrors, and map lights, as well brake lights were fine. I'm thinking some short or computer problem. So far so good.
