The engine locked up after blowing the top part of the engine off, fire shot out of the engine and quickly went out like a flam thrower. I was driving on the expressway when the accelerator would not work without any warning I didnât have any issues with this truck. The car cut off immediately thank God I was able to coast to the side of the expressway because it stopped in the left lane on the expressway I was scared for our lives. The dealership has the truck and they said the engine is locked up. This morning s unacceptable for a car Iâve had for a year.
