While applying my brakes on highway rout 87, near albany ny, the pedal went to the floor and we crashed into the car in front of us. After being towed to a aaa repair facility they told us that the brakes were fine but the steel brake line had blown out and the fluid had leaked causing loss of stoping power without any warning... We spent $890.00 plus a hotel room for one night as we waited for them to make a repair to one brake line. I recently found out all the brake lines are rotted out and need to be replaced. This makes no sense.....there is a clear safety issue here. Please reopen the case and advise a recall before a big SUV like ours hurts someone in a small car because there brake lines failed. They won't know until its to late!!!
I have a very hard time stopping the vehicle suddenly. Pedal will go all the way to the floor. ABS never activates because wheels will not even attempt to lock up. (except in snow or ice) when sitting still pedal will push entirely to the floor. Have replaced all brakes and rotors and front calipers and master cylinder. Seems to have all the symtoms of campaign number 04V045000, but when I enter my VIN number, that recall does not come up. I rearended someone about a year ago ( no damage) since then I make sure to leave about 150 feet between me and the car in front of me.

Odometer Fraud. The contact purchased a 2003 Chevrolet Suburban. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale.

I am a teacher and got a call in my classroom that my Suburban was on fire parked in the parking lot. The fire department was called and when I got outside, sure enough there was smoke all in the Suburban and smoke coming from the roof of the vehicle (not the hood). When the fire department arrived, they entered the vehicle, disconnected the battery, and proceeded to tear out my rear headliner to extinguish the electrical fire that was occurring. My insurance company had the vehicle towed and it was deemed reparable, which I was not too happy about seeing as we don't really know the cause of the fire beyond electrical. The fire originated near the rear dome light and burned the headliner and melted the paint off the roof the vehicle. …

Consumer stated that his 2 yr old son was able to pull his vehicle out of park without stepping on the brakes. He stated that the child was in the vehicle and was apparently playing with the gear shifter. He then moved the shift level causing the vehicle to roll backward hitting a pole and bending his front passenger side door. He stated he does not think this vehicle has a shift interlock, which will not allow the gear shifter to be moved without stepping on the brakes first. He stated he took the vehicle to the dealer and they did not know this either. The consumer stated the interlock only works when the key is in the ignition to drive.
Revving of engine to point of screeching tires. Sometimes feeling of being in neutral for a second then clunk in tranny/rear end? Acts as engagement of cruise control increasing speed, not able to disengage by hitting brake. Computer did not show anything. Next time putter "locked out" tech's. Puter replaced. Worked good for two weeks. Engine revved, hit patch of ice, totaled out z-71. Thank god, no injuries. Fighting it for appx 16000 miles. 72000 to 88000.
