What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
While driving approximately 35 mph, the steering failed, the front passenger wheel detached from the vehicle, the passenger side front end dropped, and the vehicle slid into a parked truck. The air bags failed to deploy. There were no injuries and a police report was filed.
It has a mind of its own when it wants to have power steering or not, it also turns to the left or right when the brake is applied. I am very afraid that I or someone else driving my vehicle is going to get seriously hurt if this happens again.
Tl contact owns a 2003 hummer h2. While driving 35 mph, the front passenger side tire fell off and the contact crashed into a parked vehicle. The vehicle was towed to her residence. The insurance investigator stated that the steering knuckle failed at the ball joint. The current and failure mileages were 56,000.
I flipped once but knocked both front tires off. I drive a lot(150 miles a day on average) and have never had a wreck. This was ridiculous, I feel like I clearly lost my steering on my front right(passenger side) and the more I think about it the more I feel like that's what happened.
Upon impact, frontal air bags failed to deploy. Driver sustained injuries. The consumer stated that there was an on/off switch for the passenger's side air bag, but, he was unsure if it was turned on. The doctor told the consumer that if the air bag had deployed he would not have sustained serious injuries.
While stopped at a red light the vehicle suddenly started moving forward. The consumer foot was on the brake but vehicle continued to move forward. As a result the consumer rear ended the vehicle in front of his damaging it's trunk.
While turning right at 30 mph the front end dropped down. This caused consumer's vehicle to hit a parked vehicle. The vehicle was towed. Dealership was notified, but did not resolve the problem.
I had no brakes and little other control. After the h2 hit the tree, it came to a stop. The bottom of the tree stayed stationary, but the top of the tree broke off and came down (hard) on the right windshield post, bending the post and shattering the windshield.
