This vehicle has severe front end wobble which mostly occurs between the speeds of 60 - 70 mph. The steering wheel and entire vehicle begins to violently wobble so much that usually the vehicle has to be stopped on the side of the road to stop the wobble. The dealership suggested new tires which we replaced however the problem still exists. The is a common problem we have learned online with this model truck. We are very concerned that this problem may cause an accident.
