At 28000 km my 2022 Chevrolet trailboss 1500 with the 6.2 started to burn oil. It was averaging 1 litre every 2000km. The dealership told me this was perfectly acceptable for consumption on this engine. From 28000 km to 45967km I had it in multiple times due to low engine oil warnings and loss of power. At 45967km I took it to another Chevrolet dealership and they inspected my truck and determined that it was caused by piston and rings. This was done under warranty. I got the call stating my truck will be ready they are just doing a test drive to confirm the issue is fixed. When I got to the dealership they informed me it was ticking and they had to investigate further. During the test drive it collapsed a lifter. After they took my engine apart for a second time this was fixed I got my truck back. Over the course of the next month sitting my truck gave me headaches and made me sick. I found out that exhaust was leaking into my cab through my vents due to a 4 head gas monitoring device. I notified the dealership and made an appt. At 47434km my truck collapsed another lifter while I was on the highway with my wife and children in the vehicle and it started to violently shake with vibrations while trying to maintain or accelerate, all the warning lights in my dash went off and I lost all safety systems. I booked it back into the dealership to have it repaired and asked to have the engine replaced as I have had nothing but problems with it and was not happy with this truck or its reliability. I reached out to Chevrolet Canada at this point and asked to have my engine replaced or my truck replaced because this truck has had nothing but problems (many more outside of the engine) and they apologized and said the best they could do was offer me a hat. I have all service records and all service has been complete at Chevrolet dealerships. Truck has no current engine problems but still has many other problems.
