are you still under warranty, how many miles?
I'd do as recommended earlier and remove the piaa lights to see if that cures the problem, if not I'd take it back and let them troubleshoot.
ask them if they tested the TIPM FYI - out of warranty the TIPM is about a $1000K+ fix, they go for about $600 with core charge and you do need to get the one for your VIN or the dealer may charge extra to flash it.
Both rear doors on mine went out and it's traced back to the TIPM, the $1000 quote is what I got from a local repair shop, I called the dealer and they wanted more, I now have manual rear doors ...
because the rear door relays are on the bottom layer of the TIPM it's not repairable.
