2007 CHEVROLET TRAILBLAZER Complaints

AFTER WE FILL THE GAS TANK, THE NEEDLE WILL GO TO 1/2 FULL THEN AS WE DRIVE FURTHER THE NEEDLE GOES ALL THE WAY DOWN TO EMPTY AND THE EMPTY LIGHT COMES ON. *TR

THE CHEVROLET TRAILBLAZER HAS SEVERAL COMPLAINTS ON-LINE ABOUT THE FUEL GAUGE NOT OPERATING ACCURATELY AND THE NEED FOR THE FUEL SENDING UNIT NEEDING TO BE REPLACED ON SEVERAL VEHICLES THAT ARE RELATIVELY NEW. THIS IS AN INCREDIBLE NUISANCE. I HAVE OWNED SEVERAL VEHICLES IN MY LIFE AND HAVE NEVER HAD TO REPLACE THIS PART IN ANY CAR. I NOW HAVE A 2007 TRAILBLAZER AND HAD TO SPEND ALMOST $600 ON THIS PART. I AM CURIOUS WHY THERE ARE SO MANY COMPLAINTS ON LINE AND WHY THERE ISN'T A RECALL ON THIS? *TR

2007 CHEVY TRAILBLAZER GAS SENSOR HAS MALFUNCTIONED. FOUND OUT THAT IT IS NOT UNDER WARRANTY! I HAVE FOUND MANY COMPLAINTS ABOUT THIS ON THE INTERNET. THERE SHOULD BE A RECALL ON THIS PART AND IT SHOULD BE REPLACED OR COVERED BY MY WARRANTY! *TR

2WD 2007 TRAILBLAZER SUPER SPORT GOES WIDE OPEN THROTTLE AFTER START UP AND SELECTING REVERSE. THIS IS WITH FOOT ON BRAKE TO SHIFT AND NO THROTTLE APPLIED OR TOUCHED SINCE START UP. VEHICLE WAS IN A PARKING LOT. ENGINE WENT FULL THROTTLE AND SMOKED REAR WHEELS JUST AFTER SELECTING REVERSE. THIS DRAGGED THE FRONT WHEELS BACKWARDS A SHORT DISTANCE WITH THE FRONT BRAKES LOCKED UP. SHIFTING TO NEUTRAL HAD THE ENGINE GO OVER THE 6500 RPM REDLINE IGNORING ALL PCM PROGRAMMED REV LIMITERS. (REV LIMITERS: 4000 RPM IN NEUTRAL AND 6500 RPM IN GEAR.) DEALER FOUND DTC U1017 LOSS OF SERIAL COMMUNICATIONS FOR CLASS 2 DEVICES. I KNOW OF 4 OTHER 2007 TRAILBLAZER SUPER SPORT THAT HAVE RANDOMLY GONE WIDE OPEN THROTTLE. THIS IS AN ADDITIONAL PROBLEM SINCE COMPLAINT NUMBER : 10269455 THROTTLE HANG UP - NOT ALWAYS RETURNING TO IDLE POWER. *TR

THE ELECTRONICS ON MY 2007 CHEVY TRAILBLAZER HAVE GONE OUT WHICH INCLUDES THE BRAKE LIGHTS AND THE FUEL GAUGE. THE REPAIR ON THE BRAKE LIGHTS WAS MINIMAL BUT IT WILL COST OVER $800 TO REPAIR THE FUEL GUAGE. CHEVROLET HAS KNOWN ABOUT THESE PROBLEMS FOR YEARS BUT HAS NOT ATTEMPTED TO FIX THEM OR RECALL THE VEHICLES. *TR

TL*THE CONTACT OWNS A 2007 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE FUEL LIGHT TURNED ON INTERMITTENTLY WHICH CAUSED THE CHECK ENGINE LIGHT TO ILLUMINATE. THE FAILURE OCCURRED EVEN AFTER THE FUEL TANK WAS FULL. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALERSHIP WHERE THE CONTACT WAS INFORMED THAT THE FUEL LEVEL SENSOR WAS DEFECTIVE. THE VEHICLE HAD NOT BEEN REPAIRED AT THE TIME OF THE COMPLAINT. THE CONTACT HAD NOT SPOKEN WITH THE MANUFACTURER. THE VIN WAS UNAVAILABLE. THE CURRENT MILEAGE WAS APPROXIMATELY 45,000. THE FAILURE MILEAGE WAS APPROXIMATELY 44,000.

VEHICLE INSTRUMENT PANEL LIGHTS COME ON INTERMITTENTLY. FIRST THE TRACTION CONTROL LIGHT THEN THE TIRE LIGHT. LIGHTS WOULD EITHER COME ON AND STAY ON OR BLINK, THEY WOULD EVENTUALLY GO OFF OR WOULD CLEAR WHEN TRAILBLAZER STARTED. TOOK TO DEALER WHILE UNDER WARRANTY AND WAS TOLD THAT THERE WAS A PATCH FOR THE ELECTRICAL SYSTEM AND IT WAS CORRECTED, THE NEXT WEEK THE PROBLEM BEGAN AGAIN. RETURNED TO THE DEALER AND SAID NOTHING WAS WRONG. A FEW MONTHS LATER, I TOOK VEHICLE IN FOR A ROUTINE OIL CHANGE AND MENTIONED THAT I WAS STILL HAVING TROUBLE WITH THE LIGHTS, I WAS TOLD THAT IT WAS A COMPUTER PROBLEM AND THAT IT WOULD COST 400.00 TO FIX. (THE AUTO WAS NO LONGER UNDER WARRANTY) I ASKED DEALER WHY THEY COULDN'T FIND ANYTHING WRONG WHEN CAR WAS UNDER WARRANTY BUT CAN FIND SOMETHING NOW. THEY TOLD ME THAT IT WAS A DIFFERENT PROBLEM. SMELLS FISHY TO ME. NOW MY CHECK ENGINE LIGHT IS ON AND I AM NOT CERTAIN IF IT IS THE PROBLEM WITH THE "COMPUTER CHIP" OR THERE IS A LEGITIMATE PROBLEM WITH THE VEHICLE. I BOUGHT THIS VEHICLE WITH 22,000 MILES ON IT AND HAVE HAD THE PROBLEM SINCE DAY ONE. UNTIL I CAN AFFORD TO FIX THIS PROBLEM, I CANNOT BE CERTAIN IF THERE IS A REAL PROBLEM WITH THE TIRES, TRACTION CONTROL OR ENGINE. *TR

THE GAS SENSOR ON THE 2007 TRAILBLAZER GOES OUT AND THE VEHICLE IS NOT ABLE TO PASS EMISSION TEST REQUIRED BY STATE LAW. I HAVE RESEARCHED ON LINE AND FOUND SEVERAL OF THE SAME COMPLAINTS FROM OTHER TRAILBLAZER OWNERS. *TR

TL*THE CONTACT OWNS A 2007 CHEVROLET TRAILBLAZER. WHILE DRIVING AT AN UNKNOWN SPEED THE FUEL GAUGE BEGAN TO READ AS IF THE FUEL TANK WERE EMPTY. UPON REFUELING THE VEHICLE THE FUEL GAUGE OPERATED NORMALLY FOR APPROXIMATELY 15 MILES BEFORE READING AS IF THERE WAS NO FUEL IN THE TANK. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHERE HE WAS INFORMED THAT THE SENDING UNIT NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED AND THE FAILURE CONTINUED TO OCCUR. THE FAILURE AND CURRENT MILEAGES WERE 36,000. THE VIN WAS UNAVAILABLE.

CHEVY TRAILBLAZER FUEL SENDING UNIT FAILED. THE GAUGE STARTING ACTING ERRATICALLY AND NOW DOES NOT WORK AT ALL. IT IS NOW EXTREMELY DIFFICULT TO KNOW HOW MUCH FUEL IS IN THE CAR AT ANY GIVEN TIME. *TR
