| May 2025 | ENGINE | My engine is out due to the piston rings failing and is at a dealership waiting for a new engine. The engine for this vehicle is on national back order with no ETA in sight. Out of nowhere the low oil light came on and I had to stop immediatley to check it as to make sure nothing happened while I was driving down the road. The dealership that has it has confirmed that the issue was due to the pistons. This vehilce was purchased brand new and has had perfect maintenance performed on it since day one. The dealership has inspected the vehicle. The low oil light first came on in February. I took it straight to a place to have them check it and change the oil again just until I could get it to the dealership a few days later. I was advised to have an oil consumption test done. On the 3rd time, which would have been around 3000 miles, it had already consumed more than a quart of oil. They did a borescope and confirmed that the pistons are bad and because of this the inside of the engine is scored. Now I need a new engine on a vehicle that I've taken perfect care of. I believe that this vehicle should be included in the GM recall with the other 6.2 engines as this is also a 6.2 engine in the same year range. I have included the paperwork from the dealership and my carfax showing maintenance. | Crash: No Fire: No | Unknown |
