Oem led tail lights have failed on my GMC with 40,000 miles on it. The bulb is good, yet the led portion (which costs over $800 to fix) needs to be replaced. This portion is the entire rear brake light housing. This is very common among these vehicles heated seats quit working on denali. The backrests still heat up, but the bottoms don't heat up at all. Also, they will not turn on in remote start mode even though they are set to turn on in this mode.
