GMC has a bulletin -??recall-?? that stated that the tail lights of their vehicles were not illuminating on vehicles. In 2019 we took our vehicle in to have the defect covered because our passenger tail light stopped working. We are now having the same issue with our driver light but they are stating that the recall only covered one light with knowledge that both lights are defective. Only one light was replaced. They also had a recall on a defective air compressor that we paid $580 for but because of mileage it was not covered. I spoke with a rep by the name of Angellica in the complaint department that confirmed that the letters regarding the air compressors were sent in November of 2017 and I did not receive that notice during that time. I purchased the vehicle in April of 2017. If any part of a vehicle is defective, or poorly made coverage should not end and defective parts should be replaced. We are looking to be reimbursed for repairs and coverage provided for the second light on our vehicle. GM refuses to resolve this issue and is placing my family in danger with defective parts on this vehicle. I am looking for this to be resolved as soon as possible. This is poor business and the quality of this vehicle that is 5 years old is poor. Attached you will see the invoice from the dealer states that the wiring is bad but coverage was expired due to mileage. If defective parts are in a vehicle there should not be a limitation on getting them replaced. GM made this mistake and it needs to be corrected.

Vehicle shuts off and on when making a sharp turn. When reversing into a parking spot the trucks steering wheel got stiff and everything shut off off then on then off and on again. When reversing it did it twice more. Turning to get out of a car wash curve it shut off and on. Turning into my driveway it shut off and on (on two different occasions)

Climate control has not been right with my vehicle since the early days of owning it. The ac and heater do not work right, resulting in defrost issues at times, creating a vision issue. You can never regulate the cabin. Now there is no ac at all. Was told it held charge, but blowing out hot air.

I purchased my truck from gilroy Chevrolet in September 2019. The week we bought it my husband had to change the breaks as they needed to be changed. Shortly after within a week from that we started hearing a popping sound from the left front part of the truck. Somewhere near the axel or tire baring. I contacted the dealer and stated they had sold me a car with no breaks and with this mysterious noise. They diagnosed the car, charged me and didn't fix the problem I didn't even get reimbursed or an apology for being sold a car that had no breaks. I have taken my car to a new dealer for further diagnosis. Where they are asking me to pay for a diagnostic fee and deductible I feel the original dealer who sold me this defective car should have to pay since I have paid these due once already. Any time the steering wheel is turned all the way you feel and hear the popping noise.

The vehicle was purchased in December used. The vehicle now has 62,000 miles. Vehicle was parked overnight after working fine the day before. Went to use air conditioning and it would only blow hot air. After checking online, and with experiences from other owners, the air conditioning failures appears to be a very costly common issue but there are no recalls for the defective parts. The vehicle is still in for repairs at this time. Although this issue was not specifically safety related in my situation, the potential for safety concerns exist. Had the ac failed while the vehicle was running with children or animals inside could be fatal.

Air conditioning - we were told by the dealership July 1st 2019, an air conditioning hose has a crack in it, and thus the refrigerant has leaked out. A new hose was ordered. It is now August 13th and we still do not have our vehicle back. The dealership has dozens of vehicles that are in need of this fix ( which, we are told is not covered under any warranty since we have 50,000 miles on it). Please push GM for a recall, since the problem is a design related flaw. 2016 GMC Yukon thank you [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Brake lights & torque converter 2016 Yukon denali. The brake light is out on the passenger side. I brought it to the dealership, and it is within 2 weeks of the warranty expiring. They had to order the part because there's a national backorder for the assembly. So clearly I'm not the only one. Did some research and this is apparently an ongoing problem. This vehicle has been a hassle from the start. I'm beginning to believe there is an electrical issue as well. I had a battery issue that the dealership couldn't figure out even after showing them the onstar alert. Originally I was told onstar was probably just sending it as a mileage alert. Turns out after I insisted they put the vehicle on a machine and it showed the battery was indeed faulty. Multiple things have gone out on a vehicle with barely 30,000 miles on it. The torque converter is also a major concern because it 'shed' metal pieces with the car having less than 20,000 miles they only drained the transmission fluid because that's what the bulletin told them to do. How is this not going to happen again? my Yukon drove like a lawnmower vibrating and hopping. This is the worst vehicle I've ever purchased, and with the issues that keep piling up it looks like we aren't anywhere near the bottom of the problems.

My ac started blowing hot air. The air compressor was changed twice. After changing it the last time I started getting the service power steering light on and Y steering wheel locks up. No power steering. This is very dangerous and seems to be come type of wiring problem.

Another mess with my 2016 Yukon sle. The A/C condenser went out at just over 60K miles -- $1600 total in repair cost. Apparently this is a known issue and GM has issued special refunds for this exact problem in prior years 2015 and before -- but has not yet done so with the 2016 year even though it is the same part and issue. I am paying to get this fixed today and counting on the special refund if not a recall.

I have 3 year old GMC Yukon XL and the condenser has gone out on it. This is about a $1,600 repair due to GMC's poor design of the location of the condenser. The labor alone is about 8 hours to replace and I find this very wrong of GMC to do to customers of such an expensive vehicle.

The antenna on the Yukon gets water in it when it rains. It has messed up my gps system and my on star system is not working. It has leaked into the SUV. This happens every time it rains.
