problem #3

Trailblazer 6 cyl

  • Automatic transmission
  • 158,000 miles

My converter went out and I also heard this is a problem with all trailblazers. I think it needs to be a recall.

problem #1

Dec 152009

Trailblazer LS Straight 6

  • Automatic transmission
  • 59,000 miles

My trailblazer had only 59000 miles on it and we were on our way back from our family reunion and our trailblazer lost all power and would not accelerate at all. As an immediate fix I just happened to have my cordless drill in the car. I drilled 3 1/4 inch holes in the front lobe of the cat/conv. and we were able to continue. Upon further investigation I found out that it would cost me over $750.00 to replace the converter. This is a very upsetting and infuriating situation.
