We have classified the 7 complaints from 2017 GMC Yukon XL about EXTERIOR LIGHTING into the following categories.
Rear passengers brake light flickers off and on causing a safety risk while driving. previous years of same make and model are having same issues causing a shortage in $400-800 replacement of tail light assembly. rather, gmc should recall and correct the original manufacturing quality to begin with.
Rear passenger led brake light failure. dealer said this is a known failure item so much so that parts are on backorder nation wide.
Right rear taillights stopped working. unit is sealed and whole assembly must be replaced, at great expense. this appears to be a common problem but gm will not fix.
Back passenger side brake lighting went out. originally it would work sometimes and not work others. not it never works... dealer said earlier years were covered by recall but not 2017. very expensive to replace and ive had the car 2 years. crazy.

Brake lights are going out without notice
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?
The whole back tail light had to be replaced after failing. poor design and a common problem on the 2015-2017 gmc yukons. there is a common area that breaks. not only a big expense but also a large waste of material considering the whole unit has to be replaced. cost is over $800.00 and the dealer buys back the old light for $50 seems a bit suspicious by gmc. these lamps are a sealed unit and were never designed to be repaired. as designed, if there is a problem, the lamp is replaced as a complete and very expensive unit. more can be found here: https://www.carcomplaints.com/gmc/yukon/2015/lights/taillight_not_working_properly.shtml
