The differential and now the cam bearings are going. The vehicle has 108,000. We did regular oil changes and maintenance on the vehicle. We even bought the extended warranty but that ran out at 100,000. Driving down the road the vehicle started to lurch then would not go over 35 mph. Front differential had a whole the size of a baseball blown out. The dealer had never seen anything like it. It was in such a place that you would not have hit anything to make this happen. Now that that is repaired we are loosing oil pressure and have been told the best way to repair this with a motor with this many miles is pull it and put a crate motor in it at $4-5,000. The vehicle itself looks like new. Now is $36,000 pile of junk! and we still owe on it!

: the contact stated the differential locked up intermittently. While the steering wheel was turned to the left, the right wheel locked. The dealership put an additive in the differential fluid, but the problem still existed. Then, they found an electric motor that activated the all-wheel drive to be defective. This caused the steering to lock when turning to left or right. This vehicle has a noise that they can't locate. Updated 06/07/2006.

2002 olds Bravada SUV. Rear differential failure at 41K miles. Dealer and GM unwilling to cover under any type of warranty. This component will normally out last the vehical. Additionally the dealer tried to sell me a complete differential assembly rather than repairing the unit for a cost of $3200. The unit was repaired by a local repair shop for a cost of $2016.
