Both led tail light fixtures went out at once, both non functioning. Have to replace both fixtures costing over $1400 from a GM dealership.

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.

The contact owns a 2015 GMC Yukon. Shortly after the contact purchased the vehicle, there was an electrical failure and the radio failed to function. The dealer (penske Buick GMC of cerritos, 17720 crusader ave, cerritos, ca 90703, (877) 886-6265) replaced the radio with a warranty; however, the failure continued. Also, the vent controls failed for the air conditioner and heater. While making a left turn and a U turn, the steering wheel seized several times. The dealer indicated that they serviced the vehicle per NHTSA campaign number: 18V586000 (steering) and was aware that the recall remedy failed. The condition progressed to the point that the vehicle began to stall. The vehicle was not repaired. The manufacturer was notified of the multiple failures. The failure mileage was not available.

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.

Passenger side brake and tail led strip light short and goes out and stops working. Will work sometimes when back hatch shuts and jars it or I hit a bump. Dealership says light it out and needs replacing. Not sure why the light still comes on when jarred. Have extended warranty that was supposed to cover all this especially being electrical. Seems to be on going problem

Headlights and brake lights quit working

- Strasburg, VA, USA

All led lights have went out on right side, as well as break lights. This is a know issue to GMC, and yet they will not correct it. My quote to have it fixed was $2493 from local dealership. That is crazy. Led lights should last a whole lot longer than this. Also condensation is in the front headlight with no holes or cracks. If this happens with house windows, they are replaced by the manufacturer. There are so many complaints, I will also be contacting the better business bureau. GMC knows there is a problem with these models.

We own a 2015 GMC Yukon with only 51,000 miles on it. The rear taillights are both intermittent. Sometimes they work, sometimes they don't. I recently took the vehicle into the dealership for service and they said replacement of the entire light was the only way to fix the issue. They acknowledged that this is a known issue and that they have serviced many vehicles with the same issue. The service person advised that there is a circuit that over time breaks and the connection becomes loose. When the metal touches and a complete circuit is made, the light will turn on. When it doesn't touch (faulty), the taillight and brake lights will not illuminate. This is a major safety hazard. A simple internet search shows that this issue is very common and GM doesn't appear to be doing anything to address it. Because it involves the brake lights, this is very concerning. Not to mention, that a replacement is $800. I have already spent $800 for one side, now the other side is out as well. I feel that this should be a recall issue since it's an obvious safety issue that is caused by faulty parts. Here is just one of the links that describe this issue in detail: Https://www.cargurus.com/cars/discussion-T53845_ds768963

My taillight stoped working. When I turn my headlights on it wont turn on or when I apply my brakes. I searched the internet(facebook and fourm sites) and found thousand and thousand of people having the same issues. The brake light/running light is not a light bulb like most cars that you can just replace when it goes out. Its led.so you have to replace the whole entire light assembly and it was over $800. Led are supposed to have a long life before they go out.... this is only a 2015 I mean come on. So I had to drive in the dark and during this rain storm on freeway and regular streets with no brake or running lights which I S extremely dangerous. This is a family vehicle I drive my kids in this car. This cant keep happening. I also read that multiple people said once they bought a new assembly it went out again and stopped working down the road. This is insane.

The vehicle's tail light assembly on both the drivers and passenger's sides are defective. The solder does not hold and the vehicle's brake lights and running lights fail intermittently. The driver is totally unaware of this major issue that the brake lights are not working. In researching this problem on the internet there are numerous customers of GMC's Yukon's and denali's who are experiencing the safety problem. I realized the problem when another motorist almost struck the back of my vehicle because there were not brake lights at all. The vehicle was traveling and both brake lights failed. The signal lights will still work.

The rear taillight works intermittently. I have reported it to the dealership and the only fix is to replace the housing unit at $1500. It has been reported and is a known problem with GMC.

- Pearland, TX, USA

I have had an on-going issue with the steering, electrical and power steering and stability control. I have had repeated issues with the stability control turning off, sudden drop in electrical power, the steering wheel gets violently yanked out of your hands and sometime the car completely cuts off. Fortunately most have been at slow speeds or else the car would have flipped. It is the exact same issue other models have been recalled for but my VIN is not included in that recall. I am afraid of this issue killing me or my loved ones should it happen at speed or leave us stuck in front of on coming traffic. According to my dealer this is an issue the manufacture has know about for a while.

2015 Yukon passenger led tail light has failed. Vehicle is only 3 years old, and in addition to the tail light failure, have had 3 air conditioning system failures to date. I don't know how long the tail light has been inoperable as there was no warning or indicator to notify the driver of a tail light problem. I only discovered this problem while following my wife in another vehicle as she was driving the Yukon. Looking at the complaints lodged on both issues, I'm beginning to seriously question GM's reliability and willingness to stand behind their vehicle and parts. Always thought leds were more reliable, but looking at the number of complaints lodged, my assumptions are apparently wrong. A simple google search on Yukon tail light repair also shows a cottage industry in repairing these led tail lights has popped up, which indicates a significant problem with the design and reliability of these tail lights. If these businesses advertise a lifetime warranty on their repairs, why can't GM make the necessary modifications to their tail lights to improve their reliability. Any reasonable search shows the magnitude of this issue, so why hasn't there been a recall issued for this problem. With no notification to the driver of the vehicle of a tail light issue, this would seem to me to be a significant safety hazard that could result in accidents and or injuries/fatalities from one or both tail light failures. If leds are less reliable than the older incandescent bulbs, then go back to the older style bulbs that a vehicle owner can replace for a few dollars instead of forcing owners to have the dealership replace the tail lights every few years at $600-$750 per instance. Very concerning and unsafe. GM needs to address this issue immediately.
