My son in law was driving the car with my permission and while making a left turn the vehicle stalled; there was no steering or brakes. The steering wheel locked up during the turn and caused the vehicle to continue turning on it's own and I proceeded to hit a pole. The radio and lights were still on during this time, however, the engine shut off.
I purchased a used 2007 Chevrolet Trailblazer 15K in June 2008 form bob bell Chevrolet eastern ave. Baltimore, md. This vehicle was advertised and assured to be a GM certified vehicle which was reconditioned and 117 point inspected under GM certified used program. I don't believe that this vehicle underwent this inspection as the dealer represented because a week after purchasing the vehicle, I had brake failure and traction control malfunction that the dealer repaired and assured me that I would have no further problems, on top of that, the oil wasn't changed or air filter which was as black as the street when it was changed out. …
I had gone to a friends house and on the way home my power steering malfunctioned. I took the vehicle to a local auto repair shop and was told the power steering cooler had rusted through. I also had to replace this part on my 2003 Trailblazer not realizing there was a problem. If this part rusts out on different years of the same model there seems to be a problem. The vehicle became very hard to steer. I know for a fact that I and many other people have had problems with transmission lines gasoline lines and power steering lines. I had to replace the gasoline line and fuel pump on the 2003 , and just replaced transmission line on the 2007. I think there needs to be an engineering change on these vehicles. I also received a recall notice on the 2007 Trailblazer for the electric window switch. The notice said I would be notified when to bring my vehicle in. …
