Extremely excessive rust on underbody of my 2004 hummer h2. Brake lines, calipers, rotors, frame, suspension, etc have holes. My brakes completely failed on the highway and I crashed into a truck and a suv. Luckily used the emergency brake to eventually stop it.
Tl contact owns a 2006 hummer h2t. While driving at approximately 45 mph, the vehicle was hit by another vehicle on the front driver side. None of the air bags deployed and the on-star system did not activate.
