At highway speed the front suspension and steering wheel begin to shake violently after hitting a bump. This happens between 65 and 75 mph and I must slow to around 45 for it to stop. This is a well known problem with these jeeps and is referred to as ‘the jeep death wobble’. I took it to the dealership for inspection under warranty and they found nothing wrong. 2 weeks later it did it 3 times on a short trip down expressway.
