MY 05 TRAILBLAZER KEEPS SHUTTING OFF WHILE DRIVING DOWN A CITY STREET. IN A 2-MILE STRETCH IT SHUT OFF 5 TIMES WITH COMPLETE LOSS OF STEERING CONTROL ALMOST CAUSING A SERIOUS ACCIDENT. THE VEHICLE TREMBLED AND THEN TURNED OFF. IT HAS SHUT OFF ON ME WHILE DRIVING ON THREE OTHER OCCASIONS ON PREVIOUS YEARS BUT IT ONLY OCCURRED ONCE AND THEN STOPPED ON THOSE OCCASIONS.

WHILE DRIVING MY 2005 CHEVYTRAILBLAZER IT JUST TURNED OFF WITHOUT WARNING, AS SOON AS IT DID THE CHECK ENGINE LIGHT AND REDUCED ENGINE POWER LIGHT CAME ON(INSTRUMENT PANEL AND RADIO WERE STILL WORKING). I TRIED A FEW TIMES TO TURN IT BACK ON BUT IT FAILED TO RESTART. 15 MINUTES LATER IT RESTARTED AND I WAS ABLE TO DRIVE TO MY WORKPLACE A FEW BLOCKS AWAY, BY THE TIME I USED MY VEHICLE AGAIN(ABOUT 3HRS LATER) BOTH ENGINE LIGHTS HAD TURNED OFF. WE TOOK OUR VEHICLE TO AN AUTO REPAIR SHOP TO SEE IF THEY COULD DIAGNOSE THE PROBLEM, THEY RECOMMENDED THAT WE TAKE IT TO A GM DEALERSHIP BECAUSE THERE WERE NUMEROUS CODES SHOWING UP ON THE DIAGNOSTIC MACHINE. WE TOOK IT TO A LOCAL GM DEALERSHIP IN INDIO, CA (COACHELLA VALLEY BUICK GMC). THEY TOO SAID THAT NUMEROUS CODES WERE COMING UP BUT AFTER 1 1/2 DAYS WITH OUR VEHICLE THEY STATED THAT THE IGNITION SWITCH NEEDED TO BE REPLACED. WE TOOK IT IN TO AUTO REPAIR SHOP AND HE PERFORMED THE REPAIR THAT GMC STATED WAS NEEDED. UPON PICKING UP THE VEHICLE FROM THE REPAIR SHOP I DROVE HOME, AS I WAS PULLING INTO THE GARAGE IT TURNED OFF, A REPEAT OF THE SAME ISSUE WE WERE HAVING BEFORE REPLACING THE IGNITION SWITCH. SINCE THIS WAS ON SAT,05-03-2014 WE HAD TO WAIT UNTIL THE AFTERNOON OF MON, 05/05/2014 TO TAKE IT BACK TO THE DEALERSHIP, WE INFORMED THEM THAT WE HAD THEIR RECOMMENDED REPAIR DONE AND THAT THE VEHICLE CONTINUED TO TURN OFF. THE FOLLOWING DAY THEY INFORMED ME THAT THEY COULD NOT REPLICATE THE PROBLEM AND THAT WE COULD PICK UP THE VEHICLE. ON THURS., 05/08/2014 THE VEHICLE TURNED OFF WHILE MAKING A LEFT TURN. 20 MINUTES LATER IT TURNED BACK ON AND HE DROVE IT BACK TO THE DEALERSHIP, THEY THEN HAD THE VEHICLE UNTIL 05/12/2014; AGAIN THEY STATED THAT THEY COULD NOT REPLICATE THE PROBLEM. IT HAS CONTINUED TO REPEAT THIS SAME PROBLEM, AGAIN WITHOUT ANY WARNING OR INDICATION THAT THERE IS A PROBLEM. *TR

EXHAUST MANIFOLD ON THE 2005 CHEVROLET TRAILBLAZER EXT WITH 4.2 ENGINE LEAKS EXHAUST FUMES INTO THE AIR AND INTO THE INTERIOR OF THE VEHICLE CREATING AN EMISSIONS PROBLEM AS WELL AS A HEALTH HAZARD OF DRIVER AND PASSENGERS OF THE VEHICLE BREATHING THE FUMES. REPLACEMENT PARTS ARE NEAR TO NON EXISTENT SINCE THERE ARE APPARENTLY SO MANY OF THE VEHICLES WITH HIS PROBLEM. I HAVE BEEN LOOKING FOR A REPLACEMENT PART FOR 3 WEEKS AND NOTHING YET. HAVE BEEN TOLD BY PARTS STORES, AND DEALERSHIPS THAT THEY DO NOT HAVE THEM AND THEIR DISTRIBUTION CENTERS DO NOT HAVE THEM EITHER, NEITHER DO THE ONLINE WEBSITES. THERE ARE NO PARTS AVAILABLE IN JUNK YARDS EITHER. NO OPTIONS AT THE MOMENT AND VEHICLE WILL NOT PASS CURRENT STATE INSPECTION. *TR

I HAVE A 2005 TRAILBLAZER EXT PURCHASED NEW IN JULY 05. RECENTLY WHILE DRIVING, THE CAR HAD REDUCED ENGINE POWER, THE CHECK ENGINE LIGHT THEN CAME ON THEN MY CAR JUST SHUT OFF. IT STARTED BACK UP AFTER PULLING OFF THE ROAD BUT HAD TO ENDURE THIS THE ENTIRE TIME WHILE DRIVING HOME. WHEN I TOOK IT IN FOR DIAGNOSIS I WAS TOLD THE ACCELERATOR PEDAL SENSOR NEEDED TO BE REPAIRED AFTER HAVING THAT REPAIRED I DROVE HOME AND THE SAME THING HAPPENED WITH THE CHECK ENGINE LIGHT AND THE CAR SHUTTING OFF WHILE DRIVING. WHEN I TOOK IT BACK AGAIN THEY NOTICED AN ADDITIONAL PROBLEM " THE FUEL LEVEL SENSOR WIRING WAS CHAFFING ON FUEL PUMP GROUND TERMINAL" OR IN LAYMAN'S TERM THE WIRE WAS SITTING IN FUEL SO THEY HAD TO REMOVE THE FUEL TANK AND REROUTE THE WIRES. THIS SOUNDS VERY DANGEROUS AND IF THIS IS HAPPENING PLEASE REPORT IT. THERE ARE TSB REPORTS ON THE ISSUE WITH THE ACCELERATOR PEDAL BUT GM HAS NOT ISSUED A RECALL ON THIS. THE QUESTION IS WHY NOT? I HAVE ALSO HAD TO HAVE THE OUTPUT SHAFT SEAL ON THE TRANSMISSION REPLACED LAST YEAR AND AGAIN THIS YEAR. NOT VERY HAPPY WITH THIS VEHICLE. IN MY OPINION THESE ARE VEHICLE DEFECTS NOT PROBLEMS YOU SHOULD BE HAVING WITH THE NORMAL MAINTENANCE ISSUES. GM NEEDS TO ISSUE RECALLS TO HAVE THESE ISSUES RESOLVED. OH IN ADDITION TO THE OTHER PROBLEMS I ALSO JUST HAD TO HAVE THE THERMOSTAT REPLACED IN EARLY JUNE. *TR
