What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Dt*: the contact stated the air bags did not deploy in a frontal impact accident at 50 mph. The air bag warning light was not illuminating prior to the accident. The dealership told the contact to call the manufacturer. The vehicle was totaled as a result of the accident. The contact sustained. Injuries.
Went from 45-0 mph in a few feet (almost flipped other suv), yet air bags did not deploy. Force caused seatbelt to completely stretch out and lock in place permanently. (would not retract afterwards) all witnesses including police, tow truck, and insurance company say airbags should have deployed.
However, the first time my sister was driving and had a brake failure with a car load of family aboard, in jacksonville fl. A nationally known company replaced the portion of the brake line that ruptured, but they did warn me that rust was rampart because of the salt. Yesterday, I was driving to work on i495, d.c.
The anti lock brake warning light illuminated. The failure recurred multiple times. The contact independently removed the anti lock brake fuse. The vehicle was not diagnosed or repaired.
The brakes went to the floor. I pumped them repeatedly which did not help much at all. I was not able to slow down, much less stop at the stop sign. With no choice, I rounded the turn at a high rate of speed. Thankfully the approaching vehicle was able to avoid me.
Tl* the contact owns a 2002 gmc yukon. The contact stated that the ignition failed and it took several attempts to get the ignition switch into the start position. The contact's personal mechanic advised that the ignition switch needed to be replaced. The vehicle was not repaired.
The contact stated the spare tire separated from the vehicle while driving. The contact examined the vehicle and noticed that the spare tire cable failed to secure the due to corrosion. The vehicle was not taken to the dealer for diagnostic testing. The vehicle was not repaired.
Updated 04-15-10 the consumer stated after having a conversation with gm and the dealer a new power steering pump was ordered. The power steering pump was replaced on april 13th. Updated 05/05/10.
