   Driving on the interstate and the truck had a horrible vibration. It smoothed out and it did it again. I got off at the next exit and the engine was making a horrible knocking noise. I had it towed to my Chevy dealer for inspection. They drained the oil and found excessive metal in the oil. They decided that the engine needs to be replaced. The truck only has 4524 miles on it and it was purchased in June of 2026.

This made vehicle extremely difficult to maneuver safely out of the flow of traffic. The engine seizure was confirmed by a Chevrolet dealership. And the engine was replaced by the Chevrolet dealership. There were no warning lamps. The engine made some unusual noises moments before failure.
