Eight problems related to tail light switch have been reported for the 2017 GMC Yukon. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2017 GMC Yukon based on all problems reported for the 2017 Yukon.
Left and right braking lights some time do not work when braking. Only the reverse light will work while the braking light will not. To add, when the front headlights are on, some times the left and right tail lights (light that is on when not braking) and braking lights will not work. I have had two different people pull up next to me saying my brake lights are out in the last two weeks. However, I have observed when they are working in that same time span. The last two days, only the right tail/braking light is not work.
The brake light is out and a single tail light is over 500$.
Right read tail light, brake light and reverse light stopped working at 61,135 miles on odometer reading for no apparent reason.
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.
Passenger side brake and tail light quit working took to dealership for repair. Dealership said they had fixed it and had not. Took back to them and they say they can't get one it's on back order. After looking into it myself it seems to be a very common problem that gm isn't doing anything to fix but put the same lights back in that will fail again. I've asked about an updated light that wouldn't fail again and the dealership seems to have no knowledge about the lights at all. Gm needs to step up and fix the this issue as it is a safety problem.
Rear passenger tail light failure. Tail light fails prematurely without any means to warn driver short of direct observation. Problem known to GMC given high number of failures and complaints of premature failures. Tail light is expensive to replace.
Tail lights intermittently work. Dealer claims full tail light assembly required to fix (at ~$850) and not covered by any warranty. Hundreds of complaints online of similar problem. Safety concern because problem is intermittent. Independent repair shops post fixes to solution by melting plastic housing and connecting metal pieces on circuit board assembly that break (this is just a thin metal plate that was poorly designed and cracks at a similar point frequently. I think this is a faulty design that exposes many customer era to great risk and should be covered by GMC. Please look into it. Car is in motion, stationary or turning when happens. Brake lights are light that is impacted.
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. . Read more...
