Rear taillight does not work. searched online and found that this is a very common issue, gm refuses to fix and tries to charge $800 to replace whole tail light assembly, and they replace with same faulty lights! fix it gmc, ridiculous
Brake lights will intermittently stop working. no consistency to when they stop working or when they start again. major saftey hazard. gmc knows about the problem but are calling it an extended warranty issue, and not fixing vehicles outside their designated time/mileage because they say it is not a safety hazard...' it is!!!
Car was parked in front of our house and combusted in the middle of the night while we were sleeping. car was exploding and engulfed in flames...completely destroyed via fire and the worst damage was in the engine compartment. cause of the fire is unknown although based on research sounds like nhtsa campaign #14v007000 or 14v152000. fire department extinguished the fire and police were on the scene.
Right rear led tail/brake light stopped working. not easily fixable. dealers are aware of the problem and make you pay $700+ a piece for a whole new assembly. the issue appears to be a faulty circuit board inside. this should be something that can be taken apart and fixed easily or gm should replace it for free.
Rear brake light assembly failing to light when brakes applied and there is not a notification to the driver. this is a manufacture flaw with the led light circuit inside the assembly. there is not a light out notification so the driver is not aware the brake light has failed. this is a safety issue and is an well known issue on the 2015-2019 yukon. this is occurring often and gmc is having problems with supplying replacements because the demand is so high from the failure. gmc has also raised the price of the brake light by 30% from $425 to $675 not including labor. i called the dealer and they informed it was a high failing item and was on backorder and not sure when they would get one. driving the vehicle without proper brake lights is a safety concern and not legal so left with little option but to stop driving the yukon.
Rear taillight randomly going on and off. interior light randomly flicker, theft deterrent system often activates, vehicle dash systems randomly reset and most recently vehicle steering wheel locked and car turned off while i was driving with my kids in the car and in a school zone!!!!! this could have been tragic and was very scary!!!!
The most disturbing concern is the fact that i lost my brakes as a result of a known problem that gm has even recognized relating to a faulty vacuum booster pump. i incurred a $500 repair bill despite gm's acknowledgement of the problem and willingness to pay for cars with less than 70000 miles. unfortunately, mine was over the allowable mileage. additionally, i am looking at a $1500 repair bill for a sealed headlight replacement and another $300 bill for a side detection system ( lane departure warning). gm made a poor car that is unsafe and is not properly addressing the problem.
Rear tail lights cut in and out. work on and off and have faulty parts.
Rear tail lamp at brake light work intermittently. it is known that the circuitry connecting the leds break.
Tl* the contact owns a 2015 gmc yukon. the contact stated that there was an intermittent electrical failure that caused the rear tail lights to short out. in addition, on several occasions, other motorists alerted the contact that either one or both tail lights were out. gettel chevrolet buick gmc (1901 tamiami trail, punta gorda, fl 33950, (941) 347-6817) was notified, but could not duplicate the failure. the failure continued intermittently. the contact purchased the vehicle from vision buick gmc (800 panorama trail s, rochester, ny 14625, (585) 200-3905) and they scheduled an appointment for diagnostic testing. the manufacturer had not issued an electrical system recall to provide a permanent remedy. the manufacturer provided a case number and was to follow-up with the dealer and the contact. the approximate failure mileage was 48,000.
Tl* the contact owns a 2015 gmc yukon. the contact stated that the passenger side tail light failed to illuminate. the vehicle was taking to walker buick gmc (1616 macarthur dr, alexandria, la 71301 (318) 542-7481) where the contact was informed that pig tail wiring was corroded and needed to be replaced. the vehicle was not repaired. the manufacturer was made aware of the failure and informed the contact that there was not a recall on the vehicle. the failure mileage was 55,000.
Both led tail light fixtures went out at once, both non functioning. have to replace both fixtures costing over $1400 from a gm dealership.
Within the last year on my 2015 my ac compressor has gone out, radio screen quit working, brake pump/booster faulty, and now rear brake light quit working. all seem to be very common in this year model. my car has less than 70000 miles on it!! gm is either doing a crappy job on their $60000 vehicles or a recall needs to be done.
Rear faulty brake lights both sides. quoted 1800 to replace. with a quick search for replacement/fix options i found a single individual that has repaired over 2000 of them. there are many more out there. this seems to be an issue with a high percentage of this make and model and gm acknowledged it by replacing the cope the 2 years later but has refused to recall this. it's an absolute safety hazard that seems to be ignored by gm
Tail light lighting strip spontaneously malfunctioned and stopped working. vehicle has no light and no brake lighting which could have resulted in auto accident. within a month the headlight has burned out resulting in a blinker malfunction. vehicle was on highway when both lights malfunctioned
