In owners' own words
LED Taillight failure REAR DRIVERS SIDE. This seems to be a common occurance amongst GMC Yukon Denali XL, where the circuit housing for the LED board begins failure with fissure within the electrical contact points. The fissure soon erupts causing a shunt within the LED semiconductor and causing the brake lights to cease functioning. Exterior lighting
The led rear brake lights are consistently failing on thousands of these vehicles. Dealer told me they are on back order and are unavailable as they can't keep up with demand. Without a fix, how can I safely drive the car? I have one out, if the other goes out, what is the solution? Exterior lighting
Taillights and brake lights inoperative. GMC knows of problem and refuses to repair vehicle outside of manufacturer warranty (lights failed after warranty period). I have seen SEVERAL other Yukons on the road with NO brake lights or tail lights. Extremely dangerous situation. Exterior lighting
