2017 GMC YUKON Complaints

The transmission failed while merging and almost caused a collision. After a complete transmission replacement, the fuel injectors failed causing the same issue. GM extended fuel injector warranty due to the number of similar issues, but not in my state.

This complaint is not in response to an event. It is a safety issue resulting from a common problem with this vehicle model, i.e.: brake light failure. The tail/brake light LED circuit board has a design weakness resulting in cracking of the board in 2 common locations, resulting in stop light illumination failures, which could lead to rear end collisions. GM has not issued a recall and their extended warranty allowance is inadequate, thereby leaving a significant repair expense falling to owners when the problem is encountered. The proper safety response is for GM to recall all of the vehicles with this style tail light in order to repair the circuit board weakness.

The vehicle was taken to the dealer and diagnosed that the taillight assemblies needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 41,169.

Air-Conditioning condenser failure (Special Coverage Adjustment 173326 Air Conditioning Condenser (Combi-Cooler) Refrigerant Leak) According to GM they say my VIN is not on the list...however, I'm having the exact same issue on my 2017 Yukon with 38k miles on it.

Taillights and brake lights inoperative. GMC knows of problem and refuses to repair vehicle outside of manufacturer warranty (lights failed after warranty period). I have seen SEVERAL other Yukons on the road with NO brake lights or tail lights. Extremely dangerous situation.

My tail light is faulty. It is working some, shorts out, stops working, I hit a bump, it starts working again. Almost caused a crash, the lady followed me to the store to tell me it was out. Took it to the mechanic and it was working again without any repair. Does this everyday.

Rear LED brake light stopped working. Supposed to have a vehicle lifetime lifespan. i.e. never require replacing. This light assembly was found to be defective in the previous year model and not fixed.

My car is not shifting right. I took it into GMC, and they said they corrected it. I have taken in two times for this issue already. Today I almost was in a car accident because the car would not shift properly and it shoved me forward like A car hit me from the back. The car is not shifting properly at all. And now it’s making a muffling sound and it’s like stuck in a gear. I pulled over and I parked and then I reversed and then I went to hit the gas again to try to go slowly and it jolted forward again. This is serious and needs repaie

The contact owns a 2017 GMC Yukon Denali. The contact stated while driving 25 MPH, the sunroof glass exploded without impact. The contact took the vehicle to the local dealer, where it was diagnosed with needing the sunroof glass to be replaced. The vehicle was not repaired but was pending repairs. The manufacturer had not been informed of the failure. The failure mileage was approximately 65,000.

2017 GMC Yukon Denali 4WD. Rear passenger brake light intermittently fails while driving Confusing and causing motorists behind my vehicle to receive inconsistent intermittent brake warning lights to alarm other motorists I have stopped. Someone is going to end up slamming into me because of this. It’s a dangerous common failure that needs to be address ASAP. I’m not waiting but GM’s executive corporate office will get the entire bill plus time lost and another BBB review.
