the paint was peeling on the rockers of the drivers side door on my 2014 sierra, there was a TSB for it, and was repaired 1 day before the warranty expired. i was washing with a garden hose, not even a sprayer attachment and the paint literally fell right off. this is not a pressure washer issue!!! it is a paint adhering to the primer issue, bad prep work from the factory. the TSB called for sticking masking tape to the rockers, and pulling it off, if the paint came off with the tape they will peel and respray the door.
