I have a 2011 CTS Coupe, park assist has always worked in the past. Recently I noticed that the rear bumper wasn’t the same color as the rest of the car, before I bought it someone must’ve had an accident and did a pretty bad job repainting it. I brought it to get 3-staged painted and it looks great.
Now when I turn the car on and go into reverse I get the service park assist message, none of the sensors work at this point. When I clear it and drive the car, the next time I go into reverse all the sensors work fine and it’s like nothing ever happened. If the car sits for the rest of the day or overnight, I’ll get the message again when I start it up the next day.
I’ve tried everything, I’ve cleaned the sensors, I’ve pulled and reinstalled them, I’ve checked fuses. They clearly work but only intermittently, is this a paint job problem? Was the paint applied too heavily on the sensors and is that causing the problem? Anything helps!
