In May 2024, the engine idled rough and transmission shifted hard, I was told me it was normal, and I would have to wait 2 yrs to make a transmission appointment.

I first noticed the brakes squealing in August 2025 at 15,000 miles. The dealership said I needed to resurface the front rotors. I mistook this a coating and brake debris, but it was actually the rotors warping. By 21,000 the vehicle is pulsing heavily when stopping. I went back to the dealer and this time they told me all 4 rotors are warped. GM denied coverage of the pads and rotors. Normal driving, no collisions or towing.

Upper radiator hose connection to radiator is faulty causing leak of coolant. Yes it is available for inspection upon request. Truck began to run cooling fan at full speed in the middle of winter with no warnings of high heat or low coolant. After two weeks, check engine light finally cut on to indicate low coolant flow. Coolant reservoir was subsequently checked and found to be completely empty. It is apparent this reservoir had been extremely low / empty for at least two weeks with no warnings. Without proper warning and leaking coolant, truck could have overheated. Should this had happened in dead of summer, truck could have very well overheated with no warning. The problem was…
