Chevrolet trailblazer worst car by far

<p>I bought a new 2.8 ltz trailblazer i had hassels with it from new and for 3 years now the car keeps going back for the very same problem but it got worse as time went by and now it broke down on me . It is with the dealers for 5 week again and GMSA do not even know what is wrong with the car.</p>
