As I was driving on I 5 in Oregon I experienced a complete failure of the electrical system and brake systems. The vehicle was on cruise control and when I disengaged it all of the safety warning light appeared on the dashboard. I pressed on the brakes and they were a complete failure also. At this time the dashboard lights and controls went off and I loss power. I was able to get to the side of the road when I noticed smoke coming from under the hood. I got my daughter out of the vehicle to a safe distance and opened the hood and the main fuse relay panel was fully engulfed in fire. I called 911. In the approx. 5 min. The time the fire truck arrived the truck was consumed and fully gutted out from the fire.

My 2004 H2 has a serious rusting issue with the brake lines. On 2 separate occasions I have been driving along at approximately 30 mpg and hit the brakes only to have them go all the way to the floor. Luckily I did not an accident. In both occasions the line burst due to rust. My veh. Has $103,000 lightly driven. GM needs to come out and admit they have a problem with rusting brake liens before someone gets killed

I was pulling out of my driveway in my Hummer H2 when the brake pedal went to the floor. I got out of my H2 and noticed a large amount of brake fluid running out from under the rear end near the left rear wheel. I looked under the vehicle and noticed a brake line was rusted in two. I checked under the hood and saw that the brake fluid reservoir was completely empty.

I was traveling on NJ turnpike when my brakes didn't feel right. Almost no brakes stepping to floor. Then brake failure light came on. This is a garage kept vehicle with approx 14000 original miles. Appears brake lines are corroded. One owner. How could this happen. Is there a recall how can I obtain details for full recovery or reimbursement?

The contact owns a 2004 Hummer H2. The contact stated that while driving approximately 35 mph, the brake pedal failed to respond when depressed repeatedly. The vehicle was driven uphill in combination of the emergency brake being engaged in an attempt to stop the vehicle. The vehicle was towed to an independent mechanic where the brake power booster was replaced. In addition, the master cylinder and brake lines were replaced at different times. The manufacturer was notified of the defect. The approximate failure mileage was 71,000.
