My 2003 Chevrolet Trailblazer ext has had a power steering problem starting around 15K miles. The power steering goes in and out with no warnings. When I have noticed this, the problem goes away if you push the gas pedal to speed up, but if you do not the power steering goes completely out. I have had several close calls while I would be turning into a parking space and the steering would go out. You do still have control of the steering but it is extremely hard to turn the wheel. I have several friends and neighbors with the same style truck and they all have experienced a problem as well. I find it hard to believe that this problem has not been a huge issue. My dealer, which is very good, has not received any notification about this being an issues from the manufacturing, even after they have receive several complaints themselves on this issue.

This vehicle had about 21,000 miles on it when the power steering pump started squealing when warm and turning. The dealer I had it replaced at told me that normally they get these vehicles in to replace the pump when it totally breaks and strands someone on the road without the ability to steer their vehicle. At 28,000 miles, the new pump is making the exact same noise and I am taking it in again to have it replaced. My concern is, what will happen to my vehicle's steering if it breaks and I ( or my wife ) am driving the vehicle. I am afraid that I will not be able to contol the vehicle. Obviously there is a mechanical problem with vehicle ( a 2003 Chevy Trailblazer ext ) as car and driver magazine had published a long term review of this vehicle in their December 2003 issue with their test vehicle requiring 3 new power steering pumps in 40,000 miles. So far there appears to be no real ling term fix to this problem, and I am afraid that I may lose control of my vehicle if this component fails.
