2016 GMC YUKON Complaints

The suv starts to brake on its own while driving. It came to a complete stop once and almost caused an accident.

The drivers side rear brake lights stopped working. GM did a warranty extension ( that admits an issue).but ours just expired.. this is an $800 to $1000 repair that owners should NOT have to pay.. GM refuses to cover this expense. This is an absolute SAFTEY ISSUE. Of course, any law enforcement officer will agree as they will write a safety violation ticket (as they should) I understand that owners are responsible for all maintenance of their vehicles, but this issue is a flaw in design. Most owners ( like us) can’t afford to pay this outrageous price for a simple break light replacement. As the entity of government that oversees the manufacture of these vehicles, there MUST be a safety recall!! Honestly, I am disappointed that no safety recall hasn’t been ordered for this issue. This problem is going to result in many many rear end accidents. Please fix this and save lives.

The driver’s side brake light assembly failure of no brake light when brake is applied. It can be inspected upon request. This may cause another driver to not notice intentions to stop or slowdown and cause an accident. This problem is constant. It has not been inspected. No warnings of the failure has been displayed.

Both brake lamp assemblies are non-op, no warning in dash and no fuses. GMC #SCA N182180270 stating that 2015 and 2016 Yukon. Extended warranty to 6 years or 72,000 miles. We are out of warranty as of last month. $2,500 to replace the tail lamp assemblies. No letter was sent to owners regarding this safety hazard. This should be a RECALL

The contact owns a 2016 GMC Yukon. The contact stated that while stopped at a stop sign, the driver behind her notified her that the brake lights were inoperable. There were no warning lights illuminated. The vehicle was taken to the local dealer and the vehicle was diagnosed with brake light failure. The vehicle was not repaired. The manufacturer had not been notified of the failure. The approximate failure mileage was 134,000.

I was driving with a trailer that has brakes. A warning system light came on “trailer brake system” service came on blind the digital speedometer. Brakes would not engage. A couple of day later same thin came on now with out a trailer. The warning would not go away and kept on chumming every 10 seconds.

The contact's sister owns a 2016 GMC Yukon. The contact stated that while her husband was driving at an undisclosed speed, the vehicle lost motive power. The contact's husband was able to restart the vehicle; however, the vehicle was only able to reverse but not drive forward. The vehicle was towed to the contact's residence, where it was diagnosed by an independent mechanic with transmission failure. The vehicle was not repaired. The dealer was made aware of the failure but informed the contact that the warranty had expired. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,000.

Last month the passenger tail light stopped working. We took it out not realizing that you have to replace the entire unit. So we put the tail light back in and it magically started working again. Then yesterday the driver's side tail light stopped working, so we did the same. Took it out, waited and put it back (since we know we can't just run to the store and get a new one), except this time it didn't start working. I know there's a recall on the tail lights but I can't seem to find anyone to help me. The vehicle is only 6 years old and the tail lights at $800 each, should last a lot longer than that!

Experienced tapping noise front right passenger side, took vehicle to Firestone diagnosed the problem - the vehicle was confirmed to have 2 broken exhaust manifold studs in the cylinder head. Mileage 85.407- This vehicle has never been used to tow anything.

The largest issue was today, 2/22/2022, when I was driving doing 56 miles per hour it felt like it wouldn't accelerate. Then all of a sudden, the wheel kind of jerked right and the car shifted down all on it's own and I was doing 25 mph. The check engine light came on immediately after the violent jerking happened. I was on a 4 lane highway and had to immediately pull over onto the shoulder. It was jerking forward and back as I was trying to pull over on a freeway where the speed limit is 70 mph!!! I had my 80-year-old mother in the car with me. AND YES!! It put us both at great risk! I had to call a tow truck and they towed it to a dealership 9.8 miles away. When I talked to the Assistant Manager, he said that there were 3 other GMC Yukon 2016 that had come in today - ALL WERE 2016 GMC YUKON MODELS WITH 125K MILES. My GMC has 124,700 MILES all with Transmission problems. This can't be an anomaly. So I got online and there are many, many complaints about this transmission. As a matter of fact, it appears in 2019 there was a Class Action Lawsuit about this very thing. I will not know until tomorrow for sure what the issue is - because the dealership could not get to it today. However, something significant happened. As a side note, recently I had an electrical problem where sensors, etc are all saying need to be serviced and none of them are working. I had appt today at 10:30 am to have them check this. On the way there, the violent jerking and sudden downshift and check engine light came on. I was scared to death and so I pulled over and called a tow truck. The dealership did not tell me this is a common issue, nor was I aware. The dealership told me if it is in fact the transmission - cost is $6,000!!! I need someone to contact me to discuss this.
