Power steering failure. Dealer has attempted to repair number of times nothing has worked. Quits working at any time then began working again. Numerous complaints on other site forums. My concern is not being able to turn/control vehicle. Problem began with-in 1st year of ownership. Truck now has 33,000 and just out of 3 year warranty. Gm has set-up service at another dealership. I just hope problem can be corrected. This is very scary problem to have I just don't trust the steering. I don't want myself and others end up becoming statistics. I hope gm really takes a hard look at this.
