The brake lights intermittently come on and off. Not reliable and the entire assembly has to be replaced per light in order to work. Sometimes if you hit a bump it will work for a bit then go back out. They have been removed, cleaned, but there is no way to fix them without replacing them. This is a known problem with GMC and they will not warranty or recall this issue.

This is a common issue that is not being resolved by GM. First one, now BOTH of my rear tail lights are malfunctioning due to manufacturing defects. This is a well publicized problem and I feel that GM should be responsible for continuing to ignore the issue. Replacement tail lights are approximately $750 each. There are many businesses that have sprung up solely to repair these tail lights.

Tail lights are very inconsistent of working or not working. Sometimes they work but most times they don't.

This vehicle was purchased on 7/05/2019 with miles 52,000 and the TRAILER BREAKE SYSTEM has gone bad 2 times already and I haven’t never used the trailer hook for anything is just so expensive to fixed it and goes bad again and all part we’re purchased from the dealership even the dealer said is a manufacturer error and this will keep happening because is manufacturer error was not designed correctly as a consumer I feel that I shouldn’t be paying for their mistake GMC should do recall and get this issue fixed as soon as possible and fixed it 2 times I have been at the dealership to get this issue fixed and I’ll probably be back again to get fixed and like mentioned is not cheap to fixed please do something about this matter I’ll gladly appreciate
