Trailblazer 6-cyl

  • Automatic transmission

Since I bought this vehicle August 30, 2002 I have had to bring it back to the dealership on numerous occasions for several different items. I have had both the left and right brake lights gone out, the driver side head lamp went out, the air conditioner has gone out twice(four months apart), the driver side passenger window is inoperable(we have tried to get it fixed for almost a month now with no success) and the engine cooling fan was warped and the fan clutch malfunctioned. At this point we don't understand why they haven't just recalled the whole vehicle. Luckily we have the 36,000 mile warranty still in affect but what's going to happen when it is up and the same problems keep recurring?
