“Car has been spontaneously stalling while driving at high speeds. Engine cuts out, power brakes and steering fail, no radio, etc. Vehicle loses all power. It is terrifying. Has happened at least 3 dozen times now. Several visits to dealer could not pinpoint problem. Dealers unable to duplicate stalling, although it has happened to me regularly for months - ie, every time I drive the car (with my two babies) for an extended period on the highway.”

“The inside chrome wheels of my wife's 2006 Hummer H3 are flaking off and peeling. Pieces of the debris come loose at all times (especially while the car is in motion). My biggest concern is that it will interfere with the brake pads when they are needed to slow/stop the vehicle. Since my wife and children are in this car more frequently, I do not want this to become an incident that could lead to an avoidable accident. I have pictures that detail my concern with the inside of the chrome wheels that I could send to you (should you need them).”

“I nearly hit another vehicle that pulled out in front of me today. The brake pedal is too close to the accelerator pedal on my 2006 Hummer H3. In an emergency situation, my shoe hangs up on the backside of the brake pedal and I have to turn my foot sideways to get it out from under the pedal. This is a very dangerous and annoying problem that I am afraid of. I can't fix this problem myself as the design is the cause of the problem.”

“There was a left rear wheel speed sensor that failed. The sensor sent data to the computer that the wheel was spinning when it wasn't. With no warning, the computer applied the brakes abruptly and firmly. We were in city traffic and speed was slow. My only safety concern at this time was that we would be rear-ended as we probably had no brake light operation as the brake pedal was not used. After this happened numerous times in 3-5 minutes, we then got dash error codes and lights that the ABS and traction control systems had failed. …”

“I drive a 2006 Hummer H3. In sept. 08, I was traveling about 40 MPH down a road when all of the sudden my H3 locked up, slid sideways, and almost flipped. I did not flip, and was able to get to a side street safely. The control panel read ABS traction control failure. I had the H3 towed to the Hummer dealership in georgetown texas. They said they had never heard of this type of problem before, but would check it out. After 2 days without my truck, they told me it was a sensor that failed and they replaced it. Then in october 08, the same thing happened again. …”
