ENGINE

MY TRUCK RADIATOR STARTED TO SMELL AS IF IT HAD A LEAK. I TOOK IT TO A RADIATOR SHOP. THIS SHOP HAPPENS TO BE VERY CLOSE TO THE GM PLANT IN DAYTON, OHIO. THE MAN TOOK ONE LOOK AT THE TRUCK. HE EXPLAINED TO ME THAT ALL THE RADIATORS FOR THIS TRUCK FROM THE 2001 YEARS WERE SENT TO HIM PRIOR TO INSTALLING. HE SAID THEY HAD BEEN LEFT OUTSIDE FOR A PERIOD OF TIME AND ALL OF THEM HAD TO BE CLEANED OUT BECAUSE OF HEAVY RUST. HE STATED MINE MUST OF BEEN MISSED. THE RUST IN THE RADIATOR WAS SO THICK IT WAS LIKE MUD! HE REPLACED THE RADIATOR, HOSES AND EVEN HAD TO REPLACE THE RADIATOR FLUID RESERVOIR BECAUSE IT LITERALLY HAD INCHES OF RUST IN IT. THIS IS SOMETHING THE COMPANY KNEW ABOUT AND I SHOULD NOT OF HAD TO REPLACE IT. THE NEXT THING TO HAPPEN IS TO THE DRIVE TRAIN. THE TRUCK IS MAKING A WHINING NOISE - SOUNDS LIKE SOME TIRES DO. WE HAVE TAKEN IT TO SEVERAL PLACES TO REPAIR AND NO ONE CAN FIGURE OUT WHAT IS CAUSING THE SOUND. WE HAVE REPLACED SO MANY PARTS, MANY OF THEM MORE THAN ONCE IN A SHORT PERIOD OF TIME. I HAVE PUT OVER $3000 OF WORK IN THE TRUCK JUST OVER THE LAST MONTH AND AM NOT YET FINISHED. THE BRACKETS HOLDING THE REAR SUSPENSION IN PLACE ARE CRUMBLING IN MY HAND. THE MUFFLER IS LEAKING. IT IS STALLING FOR NO APPARENT REASON. AND IS IDLING VERY FAST EVEN THO IT HAS HAD REGULAR TUNE UPS AND MAINTENANCE. THE TAILGATE IS BROKEN - YOU CAN JUST PULL IT OFF THE TRUCK. THIS IS NOT NORMAL WEAR AND TEAR. THE WHINING CONTINUES WHENEVER IT IS BEING DRIVEN. WHATEVER HAPPENED TO COMPANIES BEING RESPONSIBLE FOR THE QUALITY OF THE VEHICLE! GOD KNOWS MOST OF US CANT BUY A NEW ONE AT $35,000+ TO.

ENGINE AND ENGINE COOLING:COOLING SYSTEM

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!
