Differential Unit problems of the 2002 GMC Envoy

The contact owns a 2002 GMC Envoy. The contact was driving 25 mph when the gears on the differential started grinding and detached from the vehicle. The vehicle was towed to a local mechanic where the mechanic confirmed the front differential failure. The manufacturer was not contacted. The vehicle was not repaired. The failure and current mileages were 131,000.

I was driving along interstate 75 at night with my 3 year old, 16 year old, and 18 year old nephew returning to college after winter break on Jan. 2,003. We were left stranded on the side of the highway, after we almost wrecked. The gears were jumping back and forth from 2 wheel to wheel drive. I took to a local gm dealer and they told me that it would costs me 2500 to repair-the problem the front differential. I contacted the 1800 gm service line and they said that they would not be assisting with repairs due to mileage. I asked around at different auto repair and transmission shops and they said that gm knows they have a problem with the differential in Envoys, trailblazers, and isuzus. Even if the problem gets fixed, im told there is no guarantee that the problem will not happen again until gm addresses the actual problem with the differentials. I believe my gear problem caused the differential to fail. Meanwhile I am stuck with a car that I have to pay for another year and a half on. It is really an inconvenience to me. I cannot afford the repair, the car sits in the driveway. Im behind on my car payment, having to rent a car to drive to work. Gm should be held accountable. Other problems include the clutch fan going out, costing me over $500 to repair on my own. Gm refused to help. This went out at 33,000, shortly after purchase. I am really burdened right now and don't know what to do.

We purchased a $33,000 new vehicle in October. We immediately noticed the passenger front seat seatbelt locks then starts to tightening and never unlocks. I brought the issue to the service department, the new car sales manager, and Gmcs attention. Dean cloud in bentleys service department told me that the seatbelt is designed to lock so a childs safety seat can be put in the front seat. I showed him that the visors in the car and the users manual say never put a car seat in the front with the air bags. He said that the passenger must unhook the seat belt every few minutes then reconnect it. I find this unacceptable. The dealership is putting the passengers in the vehicle in an unsafe and illegal situation by telling them the only solution is to disconnect the seatbelt while the vehicle is in motion. The seatbelt in its current condition is choking the passengers, which is also unsafe. The seatbelt needs to be repaired or replaced. The differential unit had to be replaced. The bearings did not have enough tourqe (that is wht the dealer told me).
