ELECTRICAL SYSTEM:IGNITION

WE HAVE A 1997 GMC SONOMA WITH A VOTREC 4.3 X. OVER 2 YEARS AGO, WE STARTED GETTING MISFIRES. WE TRIED EVERYTHING WE COULD THINK OF, TO NO AVAIL. IN THE PAST MONTH I'VE PUT OVER $500 ALONE. I HAVE BEEN LOOKING IT UP ON-LINE, AND HAVE REALIZED, I'M NOT THE ONLY ONE WITH THIS ISSUE. THERE HAS EVEN BEEN A RECALL IN CALIFORNIA, BUT ONLY THERE. GM TOLD ME THEY HAVE DIFFERENT GAS OUT THERE. ANOTHER MAJOR SAFETY ISSUE HAS BEEN THE WIPER MOTOR FAILURE, THAT HAD A RECALL. GM TOLD ME MY VIN # WAS NOT ON THE LIST, BUT I BATTLE MY WIPERS AT LEAST ONCE A MONTH. I HAVE TO YANK THE BLADES HALF WAY UP THE WINDOW BEFORE THEY GRAB AND START TO WORK. ONE MORE PROBLEM THAT I NOW KNOW I AM NOT ALONE ON IS THE ISSUE WITH DEX-COOL. WE HAVE FLUSHED AND REFILLED THE SYSTEM AT LEAST THREE TIMES, ONLY TO HAVE IT GUNK-UP AGAIN. PLEASE HELP ME AND ALL THE OTHER CUSTOMERS WHO GOT TRAPPED WITH JUNK VEHICLES. WE HAVE HAD TOO MANY OTHER FAILURES TO COUNT!

ELECTRICAL SYSTEM

TO DATE, THERE HAVE BEEN ONLY NEAR INCIDENTS & NEAR CRASHES, WITH NO INJURIES. THE PROBLEM ON THESE VEHICLES, AS WELL AS THE CHEVROLET COPYCATS, IS THAT WHEN THE TURN SIGNAL IS APPLIED DURING THE DAY, THE HEADLIGHTS SHUT OFF UNTIL THE TURN SIGNAL IS SHUT OFF ITSELF. THIS CREATES A GRAVE SAFETY HAZARD THAT INADVERTENTLY SIGNALS OTHER DRIVERS AROUND YOU WHEN YOU ARE MAKING A TURN. I HAVE BROUGHT THIS TO THE ATTENTION OF THE SERVICE DEPT. OF THE DEALERSHIP THE VEHICLE WAS PURCHASED FROM, ON SEVERAL OCCASIONS, ONLY TO BE TOLD EACH TIME THAT IT IS "NORMAL" FOR THE VEHICLE MAKE. I WOULD LIKE THE MANUFACTURER THEMSELVES TO BE AWARE OF THIS SITUATION, AS IF I AM EVER IN AN ACCIDENT AS A RESULT OF THE ABOVE MENTIONED SITUATION, I WILL NOT ONLY SUE THE MANUFACTURER & DEALER, BUT THE NHTSA ALSO, FOR FAILING TO ISSUE A RECALL. IT SHOULD NOT TAKE AN INJURY OR FATALITY TO CORRECT A POTENTIALLY SERIOUS SITUATION AS THIS MOST DEFINITELY IS.
