Purchased the truck in March 2013 with approx 63K miles on it. In November 2013, stabilitrak warning came on. Took to Chevy dealer who replaced spark plug and new battery. In January 2015, stabilitrak warning light on again. Took truck immediately to dealer who hooked it up for diagnosis but did get any results. Light did not come on again until 9/8/15 when I was driving 70 mph on a highway. Service stabilitrak/service traction control/ABS all lit up. Strange noise coming from right front tire area when I attempted to slow down to pull off the highway, had no brakes. Pedal literally went to the floor. Luckily there was an incline so my vehicle slowed enough to allow me to get off the highway. Pulled off onto an emergency area just past the toll booths and had to use my emergency brake to stop. Luckily, I didn't have my 4 small children with me like I usually do. Now the extended warranty company is trying to deny my claim for repairs saying that the rust was the cause. I had the vehicle looked at by a certified authorized dealer who didn't notice the rust and I also had the truck inspected in July per MA law for safety and emissions and there was no mention of rust even though they do a pretty thorough inspection yet I, the consumer, am at fault when my wheel rips apart from the hub while traveling 70 mph"!? this is obviously a huge problem. People in the northeast drive SUVS -and come into contact with salt every winter. Isn't that the point of having an SUV?!". never again will I buy a GM and I will be sure to tell anyone and everyone I know to avoid them as well. Shame on GM for putting consumers in potentially life-threatening situations because of the obvious use of inferior materials. I hope the NHTSA takes a really close look at this problem and force GM to address it.

The wheel bearings on the right front wheel became unsealed. We were driving on a four-lane highway. The antilock breaking and stabilitrack warning lights came on. We did not know why. We continued to drive home on the interstate with about 100 miles to go. The car steering became intermittently difficult to control. Eventually we stopped when the car was pulling drastically to the right and the wheel well was smoking. At this point the right front wheel was pointed toward a right turn while the left front wheel was pointed directly forward. We had to be towed to a Chevrolet dealership. After new bearings were installed, calipers replaced, etc., the maintenance person at the dealership said that there was no reason to believe that the same thing would happen to the other front wheel. Nevertheless, the same thing did happen to the left front wheel six months later 800 miles from home except the sealed bearings made a "clunk" sound when it happened as we backed out of a parking lot. We investigated the location of Chevrolet dealerships and drove the car to a dealership about 30 miles away without incident.
