I have researched issues I am having with my vehicle , and I am having all the above listed issues , and do not wish to spend large amounts of money to pay for these cost considering I am still paying for this vehicle . …”

NHTSA complaint #10178335, filed 2007-01, 1,000 miles“Gages cluster on dashboard stopped working. I know 8 people that have this issue on there vehicle. No speedometer,tach, battery, fuel and other gages went out. When you start vehicle, put it in drive and drive. Shut off and restart. Nothing this is a safety issue.

NHTSA complaint #10837829, filed 2016-02, 80 miles“The passenger side exhaust manifold cracks. Once manifold cracks exhaust fumes make there way into the cabin of the car. Also the extra heat causes wires to melt and could be a possible fire hazard. After researching the failed part I have realized it is an extremely common problem with the trailblazers and GM has done nothing to correct this failing part”
