2015 GMC YUKON Complaints

in september the check engine light came on and the care began making aloud knocking noise. When we brought it to our mechanic he let us know that the engine had bad connection rods and I would need a new engine. The mechanic stated he has seen this multiple times on GM V8 Motors

While driving, the check engine light started to blink and there was a steady knocking coming from the engine. This is the same issues that GMC is currently recalling newer model vehicles for. Safety was at risk because the engine failure happened while driving.

As I was driving on the highway the check engine lights pops on and the engine starts stalling. The stability track light also came on and the truck was hard to maintain and drive. The truck has been maintained and serviced on a meticulous schedule. This is not the first major problem we have experienced with the truck, we had to do a full transmission replacement on the truck at an 118,000 miles mark. Me and my family have been the only drivers and owner of the vehicle and mostly on put highway miles. I am so frustrated and disappointed in the workmanship and quality of our vehicle.

Lifter failure due to AFM. Car shuttered suddenly and then threw codes and had a bad misfire with engine shaking. Spent $6,700 to rebuild.

With my child in the car, on a highway with no shoulder, I experienced lifter failure. It caused the vehicle shake and lose power with cars driving behind me at 55-60 MPH with nowhere to pull over. The engine just stopped as I was finally able to make it to a driveway safely. Problem was identified by dealership and my engine had to be rebuilt. I purchased the car second hand 3 months prior with no warning or symptoms. The car was inspected at the dealership by the extended warranty company rep. The extended warranty only cover a portion of the cost. The collapsed lifter cause damage to the camshaft and bent rods. The car only had 107,000 miles. If I were not able to pull off before the engine stopped, my daughter and I could’ve easily got rear ended on a Major state highway. The car was difficult to control due to the engine shaking the entire SUV.

Fuel line rubs between cab and tank making a hole. Fuel pours out on when driving or running. Huge fire risk. Glad I caught it before the car burned up with us in it.

While traveling at highway speed, without warning, check engine light started flashing. Pulled off the highway at the next exit and vehicle died in the middle of the road. Towed vehicle to mechanic who inspected vehicle and found no compression (zero psi) on cylinder 1 indicating a major engine failure, rendering engine unrepairable and the vehicle worthless. Either cam, lifter, piston failure in cylinder 1 causing massive engine failure and making the engine unrepairable due to metal shavings in the engine. This is the L87 engine, 6.2L V8 that has been plagued by problems by millions of GM owners. This car had been meticulously serviced and maintained with regularly scheduled full synthetic oil changes. The car have no indication of engine problems beforehand until the engine blew up at highway speeds.
