IN 2010 MY TRAILBLAZER WOULD NOT IDLE OR ACCELERATE PROPERLY, THE MECHANIC FOUND THE PRIMARY SMOG AIR PUMP NOT WORKING. COST TO ME $720.00. NEXT THE INSTRUMENT CLUSTER GAUGES STARTED JUMPING AROUND AND NOW THE SPEEDOMETER DOES NOT WORK AT ALL. ESTIMATED COST TO ME $480.00, I CAN'T AFFORD TO FIX IT.. THIRDLY THE WINDSHIELD WIPERS GO ON AND OFF WITHOUT WARNING. I WENT TO A DEALERSHIP AND A PRIVATE MECHANIC AND NEITHER COULD FIND THE WIPER PROBLEM. COST TO ME $68.00 FOR DIAGNOSTIC TIME AND LOTS OF DANGER AHEAD. SIMILAR GM VEHICLES/ SUV'S HAVE BEEN RECALLED FOR THE SAME REASONS, AND THESE VEHICLES ALL SHARE SIMILAR PARTS. MY DAUGHTERS ENVOY WAS RECALLED BECAUSE OF THE INSTRUMENT CLUSTER, REPLACED AT NO COST TO HER. SAME INSTRUMENT CLUSTER AS MY TRAILBLAZER. I CANDIDLY SPOKE WITH THE OWNER OF A CHEVY DEALER SHIP WHO SAID; "THESE PROBLEMS ARE COSTING THE OWNERS THOUSANDS OF DOLLARS AND SHOULD BE RECALLED".WITH ALL THE RESEARCH I'VE DONE IT IS CLEAR THE TRAILBLAZER IS LOADED WITH RECALLABLE PROBLEMS. WHY HAS THE TRAILBLAZER NOT BEEN RECALLED??? *TR
FUEL LEAKS AND SPILLS OUT OF THE TANK AND CAN BE SMELLED IN THE TRUCK FOR SEVERAL DAYS. *TR

DURING THE COURSE OF THIS EA INVESTIGATION, ODI OBSERVED THAT THE MAJORITY OF THE COMPLAINTS (88%) AND WARRANTY CLAIMS (94%) WERE REPORTED FOR VEHICLES THAT ARE REGISTERED FOR USE IN THE SALT BELT REGION OF THE US.THIS AREA INCLUDES 20 STATES IN THE NORTHEAST, MID ATLANTIC AND THE MIDWEST REGIONS AND THE DISTRICT OF COLUMBIA.CONSUMERS IN THE SALT BELT REGION REPORTED TO ODI THAT THEY COULD SMELL FUEL VAPORS IN THEIR VEHICLES WHILE DRIVING.UPON FURTHER EXAMINATION OF THEIR VEHICLES, THEY DISCOVERED THAT FUEL VAPORS WERE COMING OUT OF THE TOP OF THE FUEL TANK. THIS CONDITION IS CAUSED BY CORROSION OF THE RETURN AND SENDER LINES OF THE FUEL PUMP MODULE.WATER AND ROAD SALT COLLECT ON TOP OF THE FUEL PUMP LEADING TO SMALL PINHOLES APPEARING ON THE FUEL LINES.FUEL MAY LEAK AND COLLECT ON TOP OF THE MODULE AND/OR SPILL ONTO THE GROUND.THE DATA EVALUATED UNDER THIS INVESTIGATION REFLECT A RELATIVELY LOW FREQUENCY OF OCCURRENCE THAT LARGELY ARISES IN SALT BELT STATES.GM HAS EXTENDED THE WARRANTY ON THE SUBJECT COMPONENT TO TEN YEARS OR 120,000 MILES.FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED AT THIS TIME; ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.FOR ADDITIONAL INFORMATION SELECT DOCUMENT SEARCH.
