Front differential locked up without notice on highway at highway speed and almost lost control of my vehicle. Due to the front different locking up, the front driveshaft broke but did not come completely off right away and almost came through the floor of my vehicle. The floor where the drivers feet rest right underneath the brake pedal and gas pedal bent up a few inches and is almost touching the pedal. Pieces of the driveshaft flew out all over the highway and could have injured or killed someone else if it wasnât early AM when roads were empty. Dash cam footage shows the moment it happened, it felt and looks like I hit a land mine. Front differential needs complete replacement, there is a hole in my frame and much more was damaged due to this. Towed into dealer and manufacturer denied warranty claim. Arbitration determined it was a warrantable item and a lemon but the manufacturer still refuses to do anything about it except repurchase the vehicle at a discounted price. Very scary.
