THE ELECTRONIC BRAKE CONTROL MODULE (EBCM) P/N 10343433 ALL OF A SUDDEN FAILED. AS A RESULT THE DASH COMPUTER ERROR CODE C1214 FOR THE ANTI-LOCK BRAKE SYSTEM, TRACTION CONTROL HAS BEEN COMING ON CONSTANTLY. MY WIFE HAS TO PRESS THE RESET BUTTON WHEN SHE PUT THE KEY IN, WHEN THE CAR IS STARTED AND WHEN IT IS SHUT OFF. THIS EBCM IS NOT AVAILABLE THROUGH ANY WEB SITE OR DEALER AND IS BACK ORDERED. THE PROBLEM WITH THIS FAILURE IS THAT IF YOU STEP TOO FIRMLY ON THE GAS PEDDLE, THE CAR WILL GO OUT OF CONTROL POSSIBLY CAUSING AN ACCIDENT. AGAIN WITHOUT THE EBCM, THE TRACTION CONTROL AND ANTI-LOCK BRAKE SYSTEM ARE DISABLED. THIS IS A VERY GRAVE HAZARD SHOULD AN OWNER NOT BE AWARE OF WHAT HAPPENS IF THE EBCM MODULE FAILS. A RECALL SHOULD BE ISSUED IMMEDIATELY.

I BOUGHT THIS CORVETTE TO CELEBRATE THE DEFEAT OF BEAT CANCER. I DREAMED OF OWNING A CORVETTE SINCE I WAS 10 YEARS OLD, I'VE EXPERIENCED SO MUCH HEARTACHE, I FIGURED, I DON'T HAVE TOO MANY GOOD YEARS LEFT, I MIGHT AS WELL, GIVE MY DREAM A CHANCE, HA!! NO, INSTEAD IT HAS BEEN A NIGHT MARE, IT'S DRIVING ME CRAZIER THAN I WAS, ABOUT TO CAUSE ME A DIVORCE, HAD ELECTRICAL ISSUES SINCE DAY ONE!! HAS BEEN WORKED ON NUMEROUS TIMES BY ALLEN, THE CROOK I BOUGHT IT FROM, A PRIVATE MECHANIC WHO DIDN'T WANT TO "GET INVOLVED", A DEALER IN OWENSBORO KY, WHO DIDN'T WANT ME TO DRIVE IT HOME FOR SAFETY REASONS, HOWEVER, THAT'S OVER 2 HOURS FROM HOME AND I HAD NO CHOICE, BUT, A TRUE GM DEALERSHIP, AND 1 OF THE BIGGEST GM DEALERSHIPS IN THE AREA IN BENTON KY, TWICE, THE FIRST TIME WHEN I PICKED IT UP, I WENT STRAIGHT TO MY BANK PTFCU, AND IT DIED THERE AND I HAD TO HAVE A WRECKER TAKE IT BACK!! BUT MIKE REID AT COUNTRY CHEVROLET, AS WELL AS LARRY STOVESAND IN PADUCAH KY, BOTH, KNOW BEYOND THE SHADOW OF A DOUBT THAT THE CAR WAS WATER DAMAGE, ALL 3 DEALERS HAVE WITHHELD THAT DOCUMENTATION FROM ME, BUT MIKE REID DID TELL MY HUSBAND HE CAME OUT OF HIS OFFICE TO LOOK FOR HIMSELF AND YES, THERE WAS WATER DAMAGE. HOWEVER, JUST LIKE EVERYONE ELSE, THEY DON'T WANT TO "GET INVOLVED" !! JIMMY ALLEN HAS CAUSED ME ALLOT OF MONEY I DIDN'T HAVE BECAUSE A LAWYER TOOK MY MONEY, MAILED JIMMY ALLENS ATTORNEY BEFORE HE DID ME A LETTER SAYING I NO LONGER HAD REPRESENTATION, WHEN ALLEN WAS SUPPOSED TO BUY IT BACK MONTHS AGO. I HAD TO GO TO CHUCK HUTTON IN MEMPHIS TN, TO EVEN GET A REAL CARFAX, THE SERVICE DEPT TOLD ME THEY GOT RID OF IT AFTER 1 DAY BECAUSE OF SO MANY PROBLEMS, AND THAT IT HAD BEEN PAID OFF IN A SETTLEMENT, TWICE!! THE CAR IS THE DEVIL, I'M CONVINCED, AND IT'S BEEN WRECKED IN FRONT LEFT AND REAR LEFT WITH ODOMETER FRAUD.

THE ABS CONTROL MODULE HAS BECOME NON-FUNCTIONAL. THIS ELIMINATES THE SAFETY ASPECT OF ANTI-LOCK BRAKING, TRACTION CONTROL, ACTIVE HANDLING, AND ANTI-SKID CONTROL. CHEVROLET NO LONGER SUPPLIES THIS CRITICAL ELEMENT TO MY CAR'S SAFETY AND PERFORMANCE. THE DIGITAL INFORMATION DISPLAY CENTER FLASHES THAT THESE SAFETY ELEMENTS NEED SERVICING, WHICH IS ALSO A SAFETY IMPAIRMENT BECAUSE I CANNOT GET ANY DISPLAY OF OTHER FUNCTIONS OF THE CAR, I.E. MILEAGE, FUEL WARNING, OPTIONS, AND TRIP INFORMATION. THE PART NUMBER IS 10343433 (ABS CONTROL MODULE). THIS IS AN AC/DELCO NUMBER AND NONE ARE IN STOCK ANYWHERE IS THE UNITED STATES. I WAS TOLD BY MULTIPLE DEALERS THAT NONE ARE AVAILABLE AND GENERAL MOTORS WILL NO LONGER SUPPLY THIS CRITICAL SAFETY ITEM AGAIN! THIS IS A HORRIBLE SUPPORT SERVICE ON SOMETHING SO CRITICAL TO THE SAFETY OF A VERY EXPENSIVE AUTOMOBILE. THE RESPONSE BY GENERAL MOTORS IS SELFISH AND UNCARING. IF YOU TYPE ABS CONTROL MODULE FOR CORVETTE SERIES C5 IN GOOGLE, YOU WILL FIND AN UNLIMITED RESOURCE OF COMPLAINTS. I BELIEVE THIS WILL BE A SERIES OF ACCIDENTS WAITING TO HAPPEN THAT WILL CAUSE PERSONAL INJURY AND DEATH ON OUR HIGHWAYS. PLEASE INVESTIGATE AND TAKE ACTION.

THE PROBLEM STARTED AS A HIGHLY INTERMITTENT WARNING THAT THE ABS, TRACTION CONTROL, AND ACTIVE HANDLING SUSPENSION SYSTEM NEEDED TO BE SERVICED. IT WOULD USUALLY GO OFF BY SHUTTING THE CAR OFF AND RESTARTING IT. COULDN'T LOCATE THE PROBLEM. THIS YEAR WHEN I TOOK THE CAR OUT IT RESET ONCE AND THEN STAYED ON. DIAGNOSED IT, GENERATED DTC ERROR CODE C1214, INDICATING A BAD POWER RELAY INSIDE THE ABS UNIT. THE CAR NOW HAS JUST OVER 40,000 MILES. TO ANSWER AN OBVIOUS QUESTION, YES THE PROBLEM DID OCCUR A FEW TIMES WHILE DRIVING BUT IT OCCURRED PRIMARILY WHEN STARTING THE CAR. SEARCHING THE INTERNET IT SEEMS THAT THIS IS A COMMON PROBLEM ACROSS A LARGE RANGE OF GM VEHICLES USING THIS SPECIFIC ABS SYSTEM MADE BY DELPHI. IT REQUIRES REPLACEMENT F THE ABS UNIT TO REPAIR. *TR

04V060000 · Steering:column LOCKING:ANTI-THEFT Device

Feb 9, 2004

ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH ELECTRONIC COLUMN LOCK SYSTEMS (ECL), WHEN THE IGNITION SWITCH IS TURNED TO "LOCK," THE ECL SYSTEM PREVENTS TURNING OF THE STEERING SYSTEM. WHEN THE VEHICLE IS STARTED, THE ECL UNLOCKS THE STEERING SYSTEM. THE VEHICLE IS DESIGNED SO THAT IF THE COLUMN FAILS TO UNLOCK WHEN THE VEHICLE IS STARTED AND THE CUSTOMER TRIES TO DRIVE, THE FUEL SUPPLY WILL BE SHUT OFF SO THAT THE VEHICLE CANNOT MOVE WHEN THE VEHICLE CANNOT BE STEERED. IF VOLTAGE AT THE POWERTRAIN CONTROL MODULE IS LOW OR INTERRUPTED, HOWEVER, THE FUEL SHUT OFF MAY NOT OCCUR AND THE VEHICLE CAN BE ACCELERATED WHILE THE STEERING SYSTEM IS LOCKED. ALSO WHEN THE CONTROL SYSTEM SHOWS THAT THE ECL IS UNLOCKED AND THE VEHICLE IS BEING DRIVEN, THE LOCK PIN LOCATION CAN VARY. DEPENDING ON THE LOCATION OF THE LOCK PLATE RELATIVE TO THE SWITCH TRANSITION POINT, THERE COULD THEN BE CONTACT BETWEEN THE LOCK PLATE AND PIN CAUSING THE STEERING TO LOCK WHILE DRIVING .

Consequence & remedy

Consequence: IF THIS OCCURS, A CRASH COULD OCCUR WITHOUT WARNING.

Remedy: ON VEHICLES EQUIPPED WITH AN AUTOMATIC TRANSMISSION, THE DEALER WILL DISABLE THE STEERING COLUMN LOCK BY REMOVING THE COLUMN LOCK PLATE. WHEN THE IGNITION KEY IS REMOVED, THE TRANSMISSION SHIFTER WILL LOCK BUT THE STEERING COLUMN WILL NOT LOCK. ON VEHICLES EQUIPPED WITH A MANUAL TRANSMISSION, THE DEALER WILL REPROGRAM THE POWERTRAIN CONTROL MODULE, PERFORM A DIMENSIONAL CHECK OF THE COLUMN LOCK AND, IF NECESSARY, REPLACE THE LOCK PLATE. THE STEERING COLUMN ON THESE VEHICLES WILL CONTINUE TO LOCK WHEN THE KEY IS REMOVED. OWNER NOTIFICATION TO OWNERS OF 1997 VEHICLES EQUIPPED WITH AUTOMATIC TRANSMISSIONS BEGAN ON APRIL 26, 2004. OWNERS OF 1998 THROUGH 2004 VEHICLES (EXCEPT 1997-1998 MANUAL TRANSMISSION VEHICLES) WILL BE NOTIFIED BEGINNING ON AUGUST 2, 2004. THE REMAINING OWNERS (1997-1998 MANUAL TRANSMISSION VEHICLES) WILL BE NOTIFIED LATER IN 2004, WHEN PARTS ARE AVAILABLE. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438.
