What to check before you buy a 2005 Chevrolet Trailblazer

A useful visit to this page takes five minutes. YearTell does not score years and cannot see the vehicle in front of you.

  1. Look up the VIN for open recalls at nhtsa.gov. This year has 2 campaigns on file below.
  2. Fuel system. Check for fuel smell, leaks and whether it starts and idles cleanly.
  3. Electrical. Have a shop scan for stored codes and check battery, charging and any warning lights that stay on.
  4. Lights. Walk around the vehicle: headlights, brake lights and turn signals all working.
  5. Skim a few owner reports below for Fuel system. Look for the same symptom repeating.
  6. Take that list to a mechanic. Do not turn the complaint total into a score.

The airbags failed to deploy In a significant collision where hood, radiator, grill/number and both headlights were damaged. GM has been contacted and fail and refuse to do an inspection stating the issue is time barred to 10 years to original warranty of vehicle and are failing to acknowledge manufacturer defect or issue a recall. There were no warning signs/lights prior to notify that the airbags would fail to deploy in an accident.

FOR SEVERAL YEARS THE LOW BEAM HEADLIGHTS WOULD GO OFF AND ON INTERMITTENTLY. NOW, THEY ARE MOSTLY OFF WHICH MEANS I CANNOT DRIVE MY VEHICLE AT NIGHT ANYMORE UNLESS I WANT TO BLIND PEOPLE OR GET STOPPED. I HAVE CHANGED HEADLAMPS, RELAYS AND FUSES TO NO AVAIL. NOW, I SEE THAT MANY OTHERS WITH THE SAME MAKE AND MODEL SUV HAVE BEEN HAVING THE SAME ISSUE BUT NO RECALLS HAVE BEEN ISSUED FOR THIS YEAR MODEL. THIS IS A MAJOR SAFETY ISSUE WHEN WE HAVE TO DRIVE WITH THE HIGH BEAMS ON AND WHEN THE LIGHTS GO OFF UNEXPECTEDLY. IF YOU WILL ISSUE A RECALL FOR ONE YEAR MODEL HAVING A PARTICULAR ISSUE, WHY WOULD YOU NOT DO THE SAME WITH ALL YEAR MODELS HAVING THE SAME ISSUE? COME ON CHEVROLET AND NHTSA, LET'S GET THIS PROBLEM SOLVED TO SAVE SOME LIVES. IT IS VERY SCARY TO BE DRIVING AND HAVE YOUR HEADLIGHTS GO OUT AND A MAJOR PAIN TO HAVE TO BE SURE YOU ARE HOME BY DARK OR NOT BE ABLE TO GO OUT AFTER DARK BECAUSE YOUR HEADLAMPS ARE OR MAY STOP WORKING.
