What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
I had just left my home and at the first stop sign the brakes failed, the pedal went to the floor, used emergency brake to stop. Returned home and found brake fluid coming from the left front frame area under the master cylinder. Pulled wheel off and the steel brake line had ruptured. All brake lines severely rusted.
While driving the vehicle it appears the vehicle speed is not responding to the accelerator. You push down on the accelerator to increase speed while in traffic and nothing happens. This has occurred at least 3 times since we purchased the vehicle on june 17 of this year.
The consumer stated on two occasions, he experienced brake system failure which was related to oxidation and rust damage to the brake lines (metal tubing) and subsequent loss of brake fluid.
Found half of exhaust manifold bolts broken and cannot get inspected now.
The service tech advised that the metal brake line was corroded and needed to be replaced. I questioned how can that happen? Why wasn't it noticed during previous service? What caused the problem? Can this happen again? I requested investigation of parts and verification of recalls.
When the vehicle was first purchased, the instrument panel overheated and failed as soon as he drove from the lot. The dealer replaced the instrument panel at the manufacturer's expense. In addition, the vehicle stalled while driving at various speeds and without warning on at least twelve occasions.
While the contact was driving approximately 75 to 80 mph, the engine stalled without warning. The vehicle was towed to an authorized dealer and the technician stated that the failure was related to the fuel pump. The vehicle was repaired under the service warranty.
Tl contact owns a 2003 cadillac escalade ext. The contact stated that while loading his tailgate with 12 bags of 40 pound wood chips, he heard a popping sound . The contact then loaded a 13 pound bag onto the tailgate and approximately 8 to 10 bags fell onto his left leg and foot.
