In owners' own words
Our 2021 GMC Yukon XL with the 6.2L engine suffered a catastrophic failure requiring the engine to be replaced. The diagnosis was very similar to the GMC 6.2L engines that have been recalled for safety and failure reasons however our vehicle was not included in the recall. The engine only had 75,924 miles and was maintained to the manufacturer's maintenance schedule. The cost to replace the engine was $11,309.87. Engine
I experienced complete engine failure at around 76000 miles similar to a current engine recall for 2021 to 2024 6.2L V8 engines. However, my engine isn't included in the current recall. I also experienced the fuel pump control module problem requiring replacement. Again there is a recall for 2021 to 2024 6.2L V8 engines and again my engine wasn't included in this recall. Engine
Our 6.2L failed unexpectedly after regular maintenance. No warning, just the sound of knocking in the engine then loss of power and bad sounds from the engine. Stranded on side of road. GM wants to replace the entire engine without opening engine, claiming lower engine damage. Technicians say this is spun rod bearing problem that is very common. Dangerous and poor quality. Engine
