“FORTUNATELY, I HAD JUST GOTTEN OFF THE FREEWAY AND WAS LOOKING FOR AN ADDRESS AT A SLOW SPEED. ALL OF A SUDDEN THE CAR LURCHED; I HAD NO STEERING; I LOST ALL ELECTRICAL CONTROL; THE CAR GROUND TO A HALT; SMOKE CAME OUT FROM UNDER THE HOOD. I AND A FRIEND GOT OUT OF THE CAR. FORTUITOUSLY, FIRE TRUCKS APPEARED. IT TURNED OUT THEY WERE RETURNING FROM ANOTHER INCIDENT AS I COULD NOT BELIEVE THE IMMEDIACY OF THEIR RESPONSE. THEY TOOK OVER PREVENTING FURTHER AGGRAVATION OF THIS SITUATION. THE BATTERY WAS BOILING. ALL THE ELECTRICAL WIRE HARNESSES WERE MELTED. THE UPPER SUSPENSION CONTROL ARM WAS BROKEN. THE FIREMEN'S OBSERVATION WAS, IF I HAD BEEN GOING ANY FASTER, THE CAR COULD HAVE FLIPPED. AFTER BEING TOWED TO A NEARBY MECHANIC, I LEARNED THE UPPER CONTROL ARM HAD BROKEN. IT IMPAILED THE STARTER WHICH SHORTED. THAT MELTED THE WIRING HARNESSES TO AND FROM THE BATTERY, AS WELL AS BEING THE CAUSE OF THE BATTERY BOILING. THE KEY ISSUE IS THAT GENERAL MOTORS WOULD BUILD A VEHICLE WHERE THE UPPER CONTROL ARM IS SO FLIMSY IT WOULD BREAK. I HAVE READ OTHER INCIDENTS OF THE SAME THING WITH THE CHEVROLET BLAZER WHERE, FOR EXAMPLE, A PERSON WAS GOING 30MPH, THE CAR FLIPPED,…”
“IT STARTED WITH MY GAUGES BOUNCING ALL OVER GOING ON AND OFF , THEN IT FELT LIKE THE BRAKES WERE ON AND I HAD TO GIVE IT ALOT OF GAS TO GET GOING.NOW THE DASH WILL WORK WHEN I TURN THE KEY ON BUT AS SOON AS IT STARTS IT GOES OUT WITH THE EXCEPTION OF THE OIL PRESSURE AND THE CHARGING GAUGE. THE TRANSMISSION ISNT WORKING RIGHT AT ALL AND I DONT DARE DRIVE IT ANYWHERE. THE FUSE BOX UNDER THE HOOD DOES NOT TEST RIGHT, ONLY ABOUT HALF OF IT HAS POWER AND I AM AT A LOSS THERE! THERE HAS BEEN ELECTRICAL PROBNLEMS WITH IT EVER SINCE I BOUGHT IT.”
“TL* THE CONTACT OWNS A 2000 CHEVROLET BLAZER. THE CONTACT STATED THAT THE VEHICLE MADE AN ABNORMAL CLICKING SOUND EVEN WHEN THE TURN SIGNAL SWITCH WAS NOT ACTIVATED. UPON INSPECTION, THE TURN SIGNAL INDICATORS DID NOT ILLUMINATE. THE VEHICLE WAS TAKEN TO THE INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE FLASHERS WERE DEFECTIVE AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED. THE CONTACT REFERENCED NHTSA CAMPAIGN NUMBER: 01V364000 (EXTERIOR LIGHTING). THE DEALER WAS NOT CONTACTED. ALTHOUGH THE MANUFACTURER ACKNOWLEDGED THE RECALL, THEY STATED THAT THE VIN WAS NOT INCLUDED. THE FAILURE MILEAGE WAS APPROXIMATELY 167,000.”
