About 30 minutes after this started happening a warning lamp lit up.  We drove the vehicle about 2 miles to a local auto parts store to get an initial computer diagnosis of the issue.  The test resulted in a code of \"P0304\" which detected a cylinder #4 misfire and recommended a fuel injector replacement.    We brought the vehicle to a local mechanic to get the issue further evaluated.  After this evaluation, it was determined that the cylinder #4 misfire was related to a lifter failure.  The mechanic explained that this situation could possibly have caused more damage, specifically to the camshaft, but that job was bigger than he was willing to take on.  He recommended we get the vehicle towed to the dealership for further evaluation.  He also informed us that this situation was common with the engine in this vehicle and GMC is aware of it.  He directed us to some articles online that elaborated on the potential known issues related to the automatic fuel management (AFM) system and the related engine damage.  The vehicle was towed to a local GMC dealership for evaluation.  They found the failed cylinder #4 with associated lifter failure and damaged camshaft.  We went forward with the repair at the dealership.  We asked the dealership about the known engine issues with this vehicle.  They acknowledged the widespread issues but informed us that our particular VIN has not been included in any recalls or safety notifications,  so we were responsible for the repairs.  The vehicle spent nearly 3 weeks at the dealership.  One of the parts was on backorder due to a national shortage, which delayed the repair by about one week.  That seems to imply that the parts involved in this repair are in high demand, which raises the question of this being a manufacturing/parts issue that may need to be investigated further.","products":[{"type":"Vehicle","productYear":"2021","productMake":"GMC","productModel":"YUKON XL","manufacturer":"General Motors, LLC"}]}]}
