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 have a 6.2L that we took in with bad rods due to the cam. The fixed the motor and now it is consuming oil and GM says it is normal. Normal for an engine to consume quarts of oil?? I cannot trade out of the vehicle because of the extreme depreciation that these vehicles have incurred due to the known engine issues. I know others are having the same issues I just want GM to make this right and help loyal customers. 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
