In owners' own words
Leaking radiator with no ETA on parts availability and this is also an issue with the coolant valve being on back order and both have many reports of this failing as well with some google searches. The dealership has my vehicle and has been inspected by them. I also do not understand why radiators are not apart of the powertrain when it cools the most critical part the engine. If the Radiator fails the engine fails. Engine
At 46000 miles the motor was replaced because of an internal oil consumption issue after the motor was replaced at 1500 miles the motor locked up while traveling down the road they rebuilt this motor. I went to go pick it up. Drove it 20 miles and oil was blowing out the rear main seal. after this, I sold the truck back to Gwatney Chevrolet and purchased a 2024 model with a 6.2 L I have not had any problems yet. Engine
Most mornings after starting truck and driving off, it appears to be a hesitation or brief loss of power. Issue has been present for several years. It's hard to determine if it's engine or transmission issue. Truck is available for inspection. It usually occurs when leaving house in the morning so there is no safety issue because it happens within the first minute of driving. No warnings, cannot recreate issue. Engine
