Common Problems with the 2018 GMC Yukon
Powertrain, Transmission Issues:
“I was driving my vehicle and exiting the hw. The rear wheel of the driver side broke off and separated from the car which caused my car to hit the cement beerier on front and the side of the driver side of the vehicle. Then the car turned 180 degrees and hit the beerier on the passenger side and the rear of the car. The air bags never deployed and we discovered that the wheel brook off of the rear axe. No damage to the wheel. Several industry exports stated that this should never happen.”
“When the vehicle shifts from Reverse to Drive, it jerks the car so hard that it feels like the car has been hit by another vehicle. Talk to the dealership every time I have other service and their response is that "this is just what these 8 speeds do". They have tried updating the software for the shifting, but nothing seems to help. For the $$$ that this vehicle is, it is a crazy flaw in the design of the transmission. I don't love the answers I'm getting from the local dealerships.”
“Transmission failed at around 92K miles on 2018 Yukon XL SLT, during the national park trip in Apr 2023.
I had to pay out of pocket to fix it, bill was $5500.
It was very dangerous to drive as it would surge or jump at red light or roll backwards on uphill, not safe to drive at all and could go way worse with these transmission issues.
Based on research its common issues with these newer GM's and I was out of warranty with this huge bill. Not to mention I just brought it 6 months back used form dealer and had no extended warranty. This was very painful experience, and will stay away from GM. On other GM vehicles they have 100k warranty but on this one only 60k 5 yr, Also there is no easy way to contact GM all they reach out to owners to sell vehicles or warranty, but not good with customer service or quality of product.”
Engine Problems:
“2018 Yukon Denali with 37,000 miles has developed a leak in the radiator and needs replaced”
“2014-2018 Chevy and GMC's have a problem with cycling of the thermostat that causes stress fractures on the radiator leading to coolant leaks. Attached are GM bulletins on the 2014 and 2015 models. As one can see they have provided special coverage on the 2014 models to 5 years or 100000 miles for this problem.(Bulletin 15829) This is not true of the 2015 through 2018 like mine. Although they use similar verbiage in the bulletin P11513A and P11513F. It should be noted that Bulletin P11513A and F also applies to 2015 Cadillac Escalade Models, 2015 Chevrolet Suburban, Tahoe, 2015 GMC Sierra Denali, Yukon Models, Yukon Denali Models Equipped with 4.3L, 5.3L or 6.2L Engine (RPOs LV1, LV3, L83 or L86). ***Basically this is a safety hazard because when traveling highway speeds it puts car into reduced power mode and you can only drive very slow on highway or be stranded on side which is just as dangerous ***”
Suspension Concerns:
“Rear shock is leaking and ride is rough (bottoming out) can't find new shocks.”
“The front shock absorbers on my 2018 Yukon denali are leaking. The car is 2 years old with approximately 67K miles. GMC has the absorbers on back order as they are apparently being replaced frequently. I think the shock absorbers have design faults that assure they will need replacing well before the normal life of the product and therefore should be recalled and replaced with a better product. I contacted GMC customer care and they offered to replace them for $1,450 plus tax which is not an adequate solution - they should replace them for free.”
