NHTSA Complaint #10156207 — 2001 CHEVROLET MONTE CARLO

STOP & GO DRIVING. ABS WARNING LIGHT COMES ON, TRACTION CONTROL TURNS OFF, SERVICE TRACTION CONTROL WARNING LIGHT COMES ON, BRAKE PEDAL VIBRATES. ALL LIGHTS STAY ON WHILE DRIVING BUT RESET AFTER IGNITION TURN OFF/ TURN ON PROCEDURE AS DESCRIBED IN OWNERS MANUAL. NEXT DAY, SAME LIGHTS & WARNINGS. TAKE VEHICLE TO DEALER ON 4/05/06. "COMPUTER CHECKED SYSTEM CODES P1189, P0135, C1216 IN SYSTEM. ITEMS TESTED PER TROUBLE TREE. ALL ITEMS TEST GOOD." NO CHARGE. NEXT DAY, 4/6/06, SAME WARNINGS! TAKE TO DEALER AGAIN WITHOUT RESETTING WARNINGS. NO COMPUTER SYSTEM CODES SHOWING, BUT NO INPUT SIGNAL FROM RIGHT FRONT HUB. DEALER REPLACES RIGHT FRONT HUB ASSEMBLY - COST $479. VEHICLE SEEMS FINE, UNTIL ABOUT 4/20 WHEN BRAKE PEDAL VIBRATION COMES BACK AND WARNING LIGHTS COME ON AND OFF. I TURNED OFF THE TRACTION CONTROL SYSTEM AND EVERYTHING WAS FINE FOR SEVERAL DAYS. ON 4/25, WITH THE TRACTION SYSTEM OFF, THE PEDAL VIBRATION WAS BACK AND THE ABS & TRACTION CONTROL WARNING LIGHTS CAME ON AGAIN. WENT BACK TO DEALER. ALTHOUGH THEY TOLD ME THE COMPUTER CHECK SHOW CODES OF C1222 AND C1226, THE CODES DO NOT SHOW ON MY INVOICE. CODE C1226 APPEARS ON NHTSA TECHNICAL SERVICE BULLETIN ITEM NUMBER 10017271 FOR MY YEAR AND MAKE OF VEHICLE. HOWEVER THE SERVICE BULLETIN NUMBER 3500 IS NOT KNOW TO THE DEALER AS A VALID TSB NUMBER, AND THEY COULD NOT LOCATE ANY INFORMATION ABOUT IT. DEALER "DIAGNOSED AND REPLACED EBTCM, AND PROGRAMMED SYSTEM" - COST $697. I FEEL THAT BY REPLACING THE "BRAIN" (EBTCM) AND PROGRAMMING IT, THE DEALER AND/OR THE MANUFACTURER MAY BE COVERING UP A POTENTIAL SAFETY ISSUE WITH EITHER ONE OR BOTH SYSTEMS, ABS AND TRACTION CONTROL. I ALSO FEEL THAT THE DEALER PUT ME AND MY FAMILY IN A DANGEROUS POSITION BY FAILING TO DIAGNOSIS ANY PROBLEMS ON THE FIRST VISIT, AND THEN DOING IT AGAIN BY MAKING ME FEEL SAFE BY PAYING FOR A REPLACEMENT PART THAT HAS NOTHING TO DO WITH EITHER SYSTEM! *NM
