GMC Complaints

While driving down the road, my 2023 Yukon 6.2L engine shut down, shifted to neutral, and a message on the screen said “press start again” leaving my family in a powerless vehicle in the middle of the road in moving traffic. There were no warning signs nor is my vehicle included in a current recall. The vehicle will be taken to the dealership tomorrow morning.

I purchased my 2020 gmc sierra 1500 6.2L in September 2024 with 80,000 miles. 9 months later the lifters gave out. Had them replaced and 6 months later, the lifters again were bad and was knocking. They are now replacing the lifters and cam. I am so disappointed that this is happening. I hear that the 2019 and 2020 was not included in this recall! Why not!! If it’s still doing the same thing and it is the same engine, why isn’t my truck in this recall? I would like to know why? If it is doing the same thing as the recall, shouldn’t it be covered by this recall? Best, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On 5 Feb 2026 I was starting my 4-hour drive back home. 15 minutes into my drive my truck lost power, several lights and the engine light came on. Truck was sputtering and making harsh engine noises and shut off on me. I was forced to exit Loop 2 (a major highway). Once I was able to restate the truck I went straight to the dealership. This truck had the recall done 15 Oct 2025. However, this issues still occurred. The motor gave out. Truck is 83K in mileage. well under 100K. Cost estimate is $6.5K. The technician informed me that a lifter collapsed in cylinder 5. This is clearly still part of the GMC recall issue for the 6.2L engines. What is my next step in this process. If I knew there was a major issue with these Trucks, I probably would not have purchased it. All maintenance has been done with same dealership to keep all service records excess able.

To start off my truck has been to the dealership multiple time for the camera. After third time in the shop they fixed that issue. Then the infotainment started acting up after about 4 times in the shop it was fixed. They gave me the prescribed fix for the engine recall in november. Engine passed the test. Then 3 weeks ago the engine siezed up from the crank and bearings on the interstate doing 70 pulling a trailer in traffic. Leaveing me and my dad in the middle of the interstate. I had to have it towed 2 hours to my house. After the prescribed engine fix. They replaced the motor in 3 days. Great right? No they did not test drive long enough. Or they would have felt the shudder that developed after the new engine went in. It is now about to go back to the shop. Because of the shudder at low rpm and im haveing electrical issues again as well . My remote start also stopped working after the engine replacement.

Check engine light came on. Went off a little later and then came back on. Took it to the dealership where they ran codes. They changed the fuel injector and spark plugs based on the codes listed. They heard a noise coming from under the engine and felt like it was the same failure that it happened in the 2021 to 2024 Yukon models those engines had been recalled. Was quoted $15,000 for a new engine was also charged $1000 for the fuel injector and spark plugs.

Vehicle was taken to dealership and test was run. Service manager notified me it passed and told us about change of oil. Then recently engine stopped on us twice on the interstate with no power. We finally got it to the dealer and while they were test driving it lost power and they had to have it towed. Now we have been told we are needing a new engine and have not been given any time line. We have also read that many time the solution even on the new engine is not fixing all issues. We just want a safe vehicle returned to us.
