2018 GMC YUKON Complaints

Possible cam shaft or lifter failure. The engines power greatly reduced speed and sputtered which significantly slowed the vehicle down and could have caused and accident. It has been inspected by a certified GMC service shop. There was a check engine light on and it was supposed to be all fuel injectors, that didn't solve the problem the shop kept on digging and digging and said that they don't know if it is the cam or lifter. It is my understanding that this is a very common issue amongst these vehicles and puts alot of people upside down and out of a vehicle due to this issues. The service shop said that a new engine would cost up to $20k and it could take 4 weeks to 4 months to get the new engine in. They are back ordered because so many people are going through this issue. The service shop also said that they didn't know exactly when the engine would come in.

The contact owns a 2018 GMC Yukon. The contact stated that the A/C unit failed to function properly. The vehicle was taken to a local dealer where it was diagnosed that the A/C coolant line was leaking and needed to be replaced. The vehicle was repaired under warranty. The contact was concerned that the failure could cause medical health risks during high weather temperatures. The manufacturer was not made aware of the failure. The failure mileage was approximately 54,000.

After stopping and then go, like at a light or stop sign, on acceleration SUV will go slightly forward and stalls and high rev for a second and car feels like it’s dying or losing power and starts back up. I feel unsafe and that the car might stop middle of intersection from stop-and-go. Sometimes while driving I lose power driving and stepping on gas pedal has a few second lag time to pick back up. I’ve never had this issue before or any of my vehicles and I bought it new and we are original owners.

No warning light presented to warn of transmission issues. While driving is hesitating sluggish when accelerating and stalling around 60mph then shifts . Putt Putt then pick up a bit then back down.

I own a 2018 GMC Yukon Denali that keeps burning oil. I was told that the light had to be on or the issue had to be duplicated. I did an oil change and 2000 miles later the oil light came on. I was out of town so took picture of dipstick which was bone dry. The dealership GMC of Brandywine had my SUV. I am highly upset because in other states the started a lawsuit bit nothing in MD. If GM knows this is an issue then why aren't they doing something. My SUV has been down since October 16 and no ETA for the part. No loaner or rental help from GM as well.

Sunroof exploded while I was driving. Had I not had the shade closed I could have been injured by shattered glass. Glass has been replaced at the dealer of purchase, via insurance claim with my agent. There was no indication that this would occur.

GM already has extended the warrant for faulty AC Condensers model years 2015-2017. This model 2018 experiences the same exact condenser leak as the 2015-2017 models. In fact special coverage adjustment 17336 which omits the 2018 model has the same failure. This warranty should be extended into 2018 as well.

While driving I made a right hand turn. As soon as the turn was made, the powering steering completely went out. The power steering is found to fail upon cold starts, then return to normal after operating. The vehicle has been taken to gmc numerous times with no explanation as to why or how it has happened. When asked to replace the steering rack. They stated vehicle is working as expected. It is unsafe. GMC has had recalls on the steering for many years now.

Despite Wheelers fixing the vehicle’s recall, it still pulls one way and never improved.

Air conditioning intermittently working, but mostly not at all right to be a leak involved. Still need it fixed to know more.
