The vehicle was purchased new in 2004. Since that time the water pump has been replaced twice yielding a total of three water pumps. As of this writing the vehicle has been solely used for private use not commercial use. We currently have 85,000 miles on it. Three water pumps in 85000 miles is wrong as there is no longevity to the part. The problem was noticed in motion and could have caused severe engine/transmission damage if not stopped iimmeadiately.

I believe the person that sold us the trailblazer knew it was a lemon and we bought an extended warranty through finance company and professional financial services is a shady company alone with nathans auto sales. I have two disables children and this is suppose to be their transportation to surgeries therapy and school. It stays broken down all the tome within a year it has been worked on 15 times also the linkage to them shiftier is broken. I can't afford to pa for a car insurance and work on this vehicle every week. Savannah tire is a rip off too they cannot do engine just change oil. Lemon la and crappy mechanic work.
