2004 Hummer H2 Owner Comments

problem #2

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. Dealer says entire brake system needs to be replaced and the frame is also in bad shape. I did report the rust problem to GM while under the 3 year warranty but they did nothing. I neither do any cross-country driving nor am near the ocean. I am scared of driving the vehicle.

The contact owns a 2004 Hummer H2. The contact stated that during steady rainfall, water seeps through the windshield handle bar on both sides of the vehicle. On a previous occasion, the water shorted out the ignition and the vehicle began experiencing failure with the motherboard. The contact stated that the water also enters through the rear headliner. The dealer was notified on eleven occasions. The handle bar issue has been repaired, but the rear headliner still leaks. The current mileage was 26,000 and failure mileage was 4,000.
