Brake lights stopped working almost was plowed into by 18 wheeler on i-75. driver waved us over and informed us that he did not see us till right on top of us. problem appears to be systemic enough that the gmc service department told us that it was common enough that they kept the brake lights in stock. additionally there are numerous threads about this issue on the internet and even utube videos on where to remove material to access the offending circuit board to repair the known faulty circuit. the failure of these brake lights could have cost my family and me our lives. the dealership wanted to charge 1600$ to replace the brake lights. i reiterate the brake light failure is common enough that there are numerous threads on the internet to discuss the known weakness of the circuit board
For the past 3 years i have taken my truck into the dealership with complaints about intermittent brake light function. specifically the lr light was not working. once i was told i had to replace the entire assembly $800 - i came in to have the repair done, then i was told there was no issue. i returned again when the police gave me a warning about the same light. was told no issue. several times i have been alerted by other drivers that the light was out - sometimes it works if i smacked the exterior of the assembly but not consistently. now - all of the brake lights are out lr/rr and the bar. i cannot drive it safely and i cannot believe that the only option is to pay several thousand dollars to replace it. many have the same complaints. this should be a recall! we already paid several thousand dollars to buy this truck - it should not have these issues so early on. i have seen many other yukon's on the road with the same issue. my car is 2015 - the problem started almost immediately for us after purchasing. this is not acceptable.
This can be researched by hundreds of videos on youtube. poor design causes the metal to break inside the led rear tail lights which makes them inoperable. these are unsafe when these go out and it is very common. general motors does warranty their lights nor is there a recall.this is a costly repair and a safety issue
Brake light on vehicle works intermittently and is no longer safe. this is a problem gmc is well aware of and no solution in sight. cheap metal board brakes inside the lens and leaves you with no brake light. i do not want my family to be rear ended because of this professional grade? brake light failure, at any time on road.this is a 2016 gmc yukon with 22710 miles as i write. brake light has failed while moving on the city streets. this failure is currently on the passenger side brake light. trying to make appointment for repair of this professional grade brake light? before the other one brakes and put my family at risk of a accident.
Brake and taillight are going on and off intermittently. i can hit the side of the taillight and it will blink on and off sometimes. looked up online and found it is a well known issue that gmc will not fix. this is a safety hazard.
At 32,000 miles we had our back tail light go out. gmc replaced it at cost to them which was around $280 . less than 6 months later the other tail light went out and dealer told us 'lights go out'. we paid full price $680 to have it replaced. now our left tail light is out again and it'll be another $680 or more to be replaced. this is ridiculous. they are led tail lights. these she last a very long time. thousands of others are having this problem. car gurus has a blog solely about this. the odd thing is they are mostly 2015 yukon's. a recall needs to be done on this problem and the thousands of people dealing with this should be reimbursed for replacing these tail lights over and over! if you pay 60,000 for a car you should not go through this.
When opening the hatch or back of the vehicle, the lights will go on and off and the vehicle will not start up. you have to wait for 5 minutes sometimes longer for the engine to restart. the vehicle will be in stationary, i have to turn the vehicle off if i am going to open the back if i don't it messes up all the gages in front and will not operate.
Tail lights work inconsistently, dealership tells me it's common problem with my year and model.
Driver side rear brake light working intermittently, approx. 10% of the time. called dealership and said it is known issue with most denali brake lights. was quoted to replace entire assembly $900. each side for this known safety issue. this is a serious safety issue and known by gmc with no recalls available.
Rear passenger tail light needs to be replaced at a ridiculous cost. extremely poor engineering design. that is if it wasn't intentionally designed to fail. on the low end $5-600 to replace a tail light??? what a joke. sad thing is i'm lucky, many many people have had more than one light assembly go out. i've bought gm for my last 3 vehicles (envoy, tahoe, yukon) this will likely be the last time i ever buy gm.
