1 Warning problem

Failure Date: 04/05/2025

While traveling on the highway one day, my 2021 Chevrolet Tahoe began warning lights on the dashboard. Shortly after, it running roughly,, and jerking, so I pulled over to investigate. There no visible smoke, so I drove to the nearest auto parts store, where they ran a diagnostic test that returned a code of p0306. I then took vehicle back to the dealership where have always received oil changes and repairs. I have never visited any other dealership, relying on certified gm/Chevrolet dealerships. After inspecting the vehicle, they informed me that the lifters needed replacement advised that it would be best to replace the engine entirely. Upon further research, I discovered that issue has been affecting many people in our area and across the united states. This needs to be addressed, as the vehicle is only three years old, purchased brand new with zero miles, and I have not done anything out of the ordinary to cause this problem. The vehicle being 70,000 and 12. 000 for repairs is insane.
