Tl* the contact owns a 2003 gmc denali. The contact was driving approximately 40 MPH when the vehicle stalled without warning.

The failure persisted intermittently but recurred most during warmer temperatures. The vehicle was taken to two different dealers and an independent mechanic.

The SUV has intermittent stops/stalls in the middle of moving traffic. At that point the traction almost as quick as the motor powers down it resets and goes again. The gmc dealer has never been able to fix it so we went to a highly rated angies list auto repair shop and they suggested replacing the transmission which we have donor last april. Unfortunately that was no help either. I have had no luck finding a solution on the internet as well.
Dt*: the contact stated while driving 60mph under normal driving conditions, there was a rattling noise from underneath the vehicle and the vehicle proceeded to stall without warning.

I had a power steering failure that happened in a parking lot on sat. June4th shortly after turning on my air conditioning. I was attempting to leave a parking lot when I thought my engine had stalled because I had no power steering. Had the timing in the loss of power steering been in a different situation it could have been tragic for me, my family and/or others !!! I took my vehicle into keller automotive in shelby township, mi. After I had caused jim causley pontic in mt. Clemens michigan to find out if this item might still be under warranty. After I found out it wasn't I took it to kellers where they almost immediately knew what the problem was. I believe they stated that it was the shaft in the power steering pump that fails. Though they did say they have not seen it often in my model they said it was seen in other light duty gm trucks that share the same power steering pump. They stated to me that gm has upgraded their pumps to have a heavier duty shaft which was $394 for the part alone. If this is a common problem I would definitely consider it a safety issue and expect gm to announce a recall regarding this issue. I will hold on to my receipt in hopes that gm would come to the table regarding resolving this issue or that the federal safety agency could possibly force the issue if neccessary. If this is an isolated incident I'm sorry for wasting your time but I would hope that something could be done before the potential loss of life occurs if I am correct in understanding that this is not uncommon, thank you for your time and help !!, sincerely, perry m.
