BOUGHT MY TRUCK NEW IN 2004 AS MY RETIREMENT VEHICLE. I HAVE ONLY 42,000 MILES. I HAD MY INSTRUMENT CLUSTER REPLACED TWO YEARS AGO UNDER A DEALER WARRANTY DUE TO A DEFECTIVE SPEEDOMETER. WITHIN THE PAST WEEK MY TRANSMISSION HAS RANDOMLY SLIPPED FROM A DEAD STOP AS WELL AS DOUBLE CLUNKED FROM A DEAD STOP. MOST RECENTLY, THE AC IS RANDOMLY BLOWING OUT HOT AIR. I SHOULD HAVE BOUGHT A GOLF CART INSTEAD. SINCE THE TRUCK IS NOW 7+ YEARS OLD IT IS NO LONGER UNDER WARRANTY. I'M HOPING THE TRANSMISSION DOES NOT COMPLETELY SHUT DOWN AND LEAVE ME STRANDED WHILE DRIVING DOWN THE FREEWAY ON A HOT SUMMER DAY. NOTE: I WAS A VICTIM OF THE US FIDELIS EXTENDED WARRANTY SCAM. *TR

I HAVE A 2004 SILVERADO 1500 AND I HAD HEARD ABOUT A TSB FOR A PIN THAT ENGAGES THE CLUTCH ON THE AUTOMATIC TRANSMISSION FOR THE LSD REAR END. WITHOUT PREVIOUS ISSUES OR WARNING MY REAR END IN MY SILVERADO WENT OUT 2 DAYS AGO WHILE I WAS LEAVING FROM A STOP AT A RED LIGHT. THE CAR WAS RENDERED IMMOBILE AND I HAD TO HAVE IT TOWED TO MY LOCAL SHOP IN WHICH FOR EVERYTHING TO BE REPLACED IS GOING TO COST ~$2000. THIS TSB CAN SAVE ME THOUSANDS BUT SINCE THERE IS NO OFFICIAL RECALL, GM WILL DO NOTHING ABOUT IT. I KNOW JUDGING FROM THE TRUCK FORUMS THAT THERE ARE NUMEROUS OWNERS WITH THIS SAME ISSUE. PLEASE HELP GM MAKE THIS RIGHT FOR US LOYAL GM CUSTOMERS. *TR

I WAS GOING DOWN THE HIGHWAY ABOUT 50 MILES PER HOUR.HEARD A POP AND MY TRUCK WHEELS KIND OF LOCKED AND THEN ROLLED ON. I PULLED OVER AND GOT OUT AND LOOKED UNDER THE TRUCK AND FOUND NOTHING. WENT ON TO MY LOCATION AND WHEN GETTING BACK IN MY TRUCK I HAD NO REVERSE. HAD I HAD AN 18 WHEELER BEHIND BE THIS COULD HAVE BEEN A DISASTER. HAVE NOT PUT IT IN THE SHOP YET. 2004 CHEVY Z71 SILVERADO. *TR

I WAS BACKING OUT OF A PARKING SPACE IN MY 2004 SILVERADO Z71 EXTENDED CAB AND THE DRIVESHAFT BROKE IN HALF. I HAVE @106,000 MILES ON THE VEHICLE. IT IS CURRENTLY AT A REPAIR SHOP TO BE FIXED. I HAVE NEVER TAKEN THIS TRUCK OFF-ROAD. I AM VERY CONCERNED AS I HAVE READ MANY OTHERS WITH 2004 MODELS HAVE HAD THE SAME THING HAPPEN. THIS COULD HAVE BEEN A MAJOR SAFETY ISSUE HAD IT OCCURRED WHILE HIGHWAY DRIVING AS THE ENTIRE REAR DRIVESHAFT IN THE MIDDLE OF THE TRUCK WAS HANGING DOWN ONTO THE ROAD. *TR

VEHICLE SPEEDS UP, SURGES, THEN STARTS TO BUCK AND YOU GET TRANSMISSION LASH. IT HAPPENS AT ROAD AND HIGHWAY SPEEDS OF 45 OR 55 MPH, AND CAN/DOES HAPPEN IN OD OR IN 3RD GEAR. (AUTOMATIC TRANSMISSION). I HAVE HAD A THIRD PARTY "SCAN" THE SYSTEM, AND I GET "NO" CODES. CHECK ENGINE LIGHT DOES "NOT" COME ON. I AM ABLE TO REPLICATE THE ISSUE AT WILL. THE VEHICLE IS A 2004 K1500 WITH 46,500 MILES. ITS PRIMARY USE SINCE I PURCHASED THIS VEHICLE NEW IS TO TOW A 19 FOOT MASTERCRAFT FROM APRIL TO NOVEMBER. MAINTENANCE IS PERFORMED BY THE MANUFACTURES' RECOMMENDED GUIDELINES. ORGINAL TIRES, AIR AND OIL FILTERS HAVE BEEN CHANGED AS NEEDED. NO AFTERMARKET DEVICES INSTALLED. I HAVE HAD A COUPLE OF VERBAL ENCOUNTERS WITH CHEVY DEALER SERVICE DEPARTMENT. THEY SEEM TO BE CLUELESS. BUT ARE WILLING TO TROUBLESHOOT AT MY EXPENSE, PLUS COSTS OF ALL PARTS AND SERVICE HOURS. THIS COULD $1000.00 OR MORE....VERY FRUSTRATING. THIS IS A HAZARD, ACCIDENT WAITING TO HAPPEN. I HAVE SEEN SEVERAL SIMILIAR ISSUES ON THE INTERNET BLOG SITES, WITH NO CONCRETE ANSWERS. GM IS SCAMMING THE PUBLIC, AND THE GM SERVICE DEPARTMENTS ARE PASSING THE COSTS TO THE CONSUMERS. THERE SHOULD BE A RECALL AND A FIX FOR THIS ISSUE. *TR

FIRST MY BRAND NEW 2004 SILVERADO'S DRIVE SHAFT FLEW OUT ON THE FREEWAY AT 15,000 MI. THAT WAS FIXED UNDER WARRANTY. THEN AT ABOUT 28,000 MI. MY REAR END GEARS WERE MAKING WHINING NOISES EVER SINCE THE DRIVE SHAFT FLEW OUT AND I BROUGHT IT TO THE DEALER 3 TIMES BEFORE THEY FINALLY TORE IT APART AND REALIZED THE GEARS WERE DAMAGED AND THEY REPLACED THAT UNDER WARRANTY. THEN AT 65,000 MI. ON MY TRUCK THE TRANSMISSION WAS SLIPPING REALLY BAD SO I BROUGHT IT BACK TO THE DEALERSHIP AND THEY FOUND THAT A FEW GEARS WERE BURNED UP SO GM AND I SPLIT THAT BILL 50/50 TO REBUILD THE TRANSMISSION. NOW I FIND MYSELF IN THE SAME SITUATION AT 85,000 MI. ON MY TRUCK THE TRANSMISSION IT BROKEN AGAIN AND WONT EVEN WORK. THE TRUCK IS AT THE DEALER AND GM AND THE DEALERSHIP DON'T WANT TO WARRANTY ANYTHING ON IT AND WANT TO OFFER ME $2000.00 CASH BACK TO BUY A GM CAR WHICH AT THIS POINT I'VE HAD NOTHING BUT PROBLEMS WITH. CAR IS AT THE DEALERSHIP NOW AND IM WAITING TO HEAR BACK FROM GM. THIS IS THE FOURTH TIME MY TRUCK HAS BROKEN IN THE DRIVETRAIN AREA SINCE NEW. *TR
