What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I pulled into the driveway and tried to stop and there were no brakes. Tried to apply the parking brakes and the cable snapped. Stopped by driving up a hill into the grass.
He was trying an xterra and I hit hm head on near the end of his vehicle however my airbags did not deploy. The entire front end of my truck is gone, radiator is exposed and hood pushed up to the windshield.
I pulled to the shoulder and noticed that one of the brake lines forward of the abs module located inside the left frame rail directly beneath the drivers seat had ruptured due to corrosion. Further inspection showed all brake lines in that area were covered with corrosion.
The battery light comes on, after the vehicle shuts down, but no check engine light and no warning whatsoever. The vehicle just shuts down. When this happens there is no power steering and no brakes for this 7000 pound vehicle.
My son was driving my 2002 avalanche when the brake pedal went to the floor without any prior warning or dash lights. Although he did go through the intersection he was trying to stop for there was no traffic and no accident. The problem was a brake line failing.
The vehicle had been idling for several minutes and after pulling out across the highway the engine shut off. After trying for at least 10 minutes it restarted. Thought this was an isolated instance, but has now happened multiple times at various speeds and even when idling at a stop light.
I put the truck in park and was unable to put it back into gear.
The contact stated that the vehicle was equipped with dual fuel tanks and the contact noticed that the rear fuel pump wires and port were melted. The vehicle was diagnosed by an independent mechanic who informed the contact that fuel pump and related components would need to be replaced.
