Trailblazer EXT 4WD 6-cyl

  • Automatic transmission
  • 82,090 miles


I own a 2003 Chevy trailblazer lt @ 35,825 miles I reported my vehicle binds up on turns & of course the garage found nothing (drove it 20 miles for comparison @ the time). So now that I am up to 82,090 miles now I mention suspension issues still & of course they find both lower ball joints need replaced @ $320.06 & left outer tie rod end broken @ $170.80. Also they inform me I need to replace 3 of my 4 stabilizer bar links are loose & rattling @ an estimate of $320 (haven't done yet) also, I have looked on a website called mycarstats.com & found many others with these same issues with this vehicle @ much lower mileage & where tie rod issue caused an accident -- they weren't as lucky as me. Also people I work with who have this same yr & model vehicle have had to have ball joints, sway bars replaced, and other suspension work @ lower mileages. I also had an issue with my 4-wheel drive becoming inoperative & this did almost cause me to wreck going up hill during winter weather. They replaced front differential engagement actuator. All these things in my mind should not have happened at these mileages. The 4-wheel drive quit @ 80,000 miles. All these issues can create safe driving issues for the consumer especially someone who pays over $30,000 for a vehicle when it's new. Let me add now that the latest expensive repair to add to my list is the fan clutch assembly on my engine cooling fan system $573 -- also found many GM owners of Bravada, rainers, Envoy & trailblazers experiencing this items failure too.

Passenger side upper ball joint came out causing the lower ball joint to also come out resulting in a cut ABS sensor wire and a bent strut and finally a axle that ripped out of the transfer case which destroyed the case cover.
