I was driving and n the freeway around 70 miles and " TRAILER Brake SERVICE" message appears on the dash board screen We don't pulling nothing on that time and normally we don't use this car for pulling, the other message appears several times is very frustrating. I am the guy in charge for this vehicle.

Like many other complaints..when your driving and accelerating it jerks and try’s to change gears ect. Most recent issue is the temperature sensor went out and my fan was running on full speed. Well I got it fixed and within 2 months it has gone out again! Lastly, the paint on the hood and roof. When I bought the dealership fixed the hood and yet again it’s failing again..

The contact owns a 2016 GMC Yukon XL. The contact stated that while driving at an undisclosed speed, the rear passenger's side seat belt inadvertently tightened around her daughter's stomach. The contact's daughter pressed the seat belt button and unlatched the seat belt; however, she was unable to remove the seat belt because it seized around her stomach. The contact had to cut the rear passenger's side seat belt to release her daughter. The contact's daughter sustained marks on her stomach from the seat belt, but no medical attention was received. The vehicle was taken to the dealer, where the contact was offered a discount on the replacement of the rear passenger's side seat belt. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 90,000.

The OEM LED taillights can fail due to a manufacturing deficiency. A metal strip that connects the LED's to the cars taillight circuit develops a crack and interrupts current flow to the taillight LED's. The above is common knowledge to the car community and is searchable on line. Concerns: 1) If both taillights are failed at the same time the vehicle doesn't have any of the required visible markings, especially at night. 2) From an economic point of view, unlike vehicles that use incandescent light bulbs that are easily replaced when burnt out, these LED light assemblies have to be completely replaced to the cost of several hundred dollars plus labor which could/will lead to the neglecting of this repair because of the economics. 3) Unlike incandescent bulbs, LED's are should last much longer to the point of outlasting the life of the vehicle. This isn't the case when there is a manufacturing defect. In my case on 10/21/21 the defective taillight assemblies was replace under a defective taillight extended warranty agreement. I requested to have both replaced because of the odds of the second one failing. They refused. So when the opposite side assembly failed recently i was out of the extended warrant date resulting in a cost to me of $392.88 labor included. In conclusion, The well documented failure of the above taillight assemblies leads to vehicles being non conforming to FMVSS.

The contact's husband owns a 2016 GMC Yukon XL. The contact stated while driving 20-30 MPH, the message "Service Air Bag" was displayed. The vehicle was taken to the dealer, where the failure could not be duplicated. The vehicle was then taken to a second dealer, Beck & Masten Buick GMC South (12820 Gulf Fwy, Houston, TX 77034) to be diagnosed. The vehicle was not diagnosed nor repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 128,000.

There is a special policy to replace faulty tail lamps. However, the policy is only extended through 72,000 miles or 5 years which is ridiculous, and should be a recall. I had my drivers side tail lamp replaced in February 2022 because it was not working. I wasn’t aware of the mileage and year restrictions at that time. Fast forward to today, I have my passenger side tail lamp intermittently working. Now out of the specific time frame, I’m left to encounter this expense out of my own pocket. Clearly GM is aware of the problem, but has not issued a recall on the tail lamp issue. It’s not just a burned out brake light, but apparently an electrical issue with the way they were initially wired. This is a very dangerous situation, as I have no idea if and when my brake light is out. God forbid if they were to go out and I were to be rear ended due to GMs lack of taking responsibility.
