They shared Service Bulletin 22-NA-240 and said it should be covered under powertrain warranty. Brought it back to the dealership [Crown Buick GMC] January 19, 2024. They informed me Bulletin 22-NA-240 did not apply to the vehicle year (2019) was not included. They also informed me no work would be covered under warranty because it expired December 18, 2023. I continue to have to refill the coolant due to overheating, and oil is clearly present.
