I BELIEVE THAT I ALSO HAVE A PROBLEM WITH MY IGNITION AND FRONT PANEL. I CAN PULL MY KEY OUT IN ANY POSITION. EVERYTHING LIGHTS UP ON THE DASHBOARD AT ONE TIME OR ANOTHER. IT HAS CALLED MY VEHICLE TO STALL OR EVEN SHUT DOWN ALTOGETHER. I DON'T UNDERSTAND WHY MY VEHICLE HAS NOT BEEN RECALLED. I HAVE HAD IT IN SEVERAL TIMES BUT AM UNABLE TO FIND OUT WHAT THE CAUSE IS. PLEASE HELP ME. MY TRUCK SCARES ME SO MUCH, I'M AFRAID TO DRIVE IT, ESPECIALLY ON THE FREEWAY, OR ROADS THAT ARE BLACKED OUT FOR CELL PHONES, AND NO WAY TO GET HELP. *TR

BLOWER MOTOR STOPPED WORKING LAST YEAR. I HAD A NEW BLOWER MOTOR INSTALLED AND THE REPLACEMENT STOPPED WORKING. WHEN I BROUGHT MY TRUCK TO BE REPAIRED FOR THE SECOND TIME, I WAS INFORMED THAT THERE IS A PROBLEM WITH THE WIRING/RESISTOR WHICH SUPPLIES POWER TO THE BLOWER MOTOR. APPARENTLY, THE MOTOR PULLS MORE POWER THAN THE WIRING IS RATED FOR WHICH CAUSES IT TO HEAT UP AND BURN THE INSULATION OFF OF THE WIRING UNDER THE DASHBOARD. MY MECHANIC TOLD ME THAT I SHOULD CONSIDER MYSELF LUCKY THAT MY TRUCK DID NOT CATCH FIRE LIKE ANOTHER CUSTOMER'S TRUCK HE HAD RECENTLY REPAIRED FOR THE SAME REASON AS MINE HAD. I FEEL THAT I HAVE PAID FOR REPAIRS TWICE DUE TO DEFECTIVE GM PARTS. *TR

WE LOST OUR VEHICLES AND 90% OF EVERYTHING WE OWN. IT WAS DETERMINED TO BE THE ENGINE BLOCK HEATER IN OUR 2002 CHEVY SILVERADO 2500 HD. WE HAVE BEEN IN CONTACT WITH GENERAL MOTORS. WE GAVE THEM ALL THE FIRE REPORTS FROM BOTH WEST VALLEY CITY FIRE DEPARTMENT AS WELL AS THE REPORT AND PICTURES PROVIDED BY THE INVESTIGATOR.

THE CAR WAS OPERATING NORMALLY AS I WAS LEAVING THE PARKING LOT AFTER SHOPPING. THE ENGINE WAS AT NORMAL OPERATING TEMPERATURE. THE ENGINE STALLED, LOST POWER BRAKES AND STEERING. THIS OCCURRED FIVE TIMES IN A PERIOD OF APPROXIMATELY ONE WEEK. THE ENGINE WOULD RESTART AFTER ONE MINUTE OR MORE. THERE WERE NO SES OR MIL INDICATIONS OR DTC CODES. I GOOGLED THE FAILURE AND FOUND SEVERAL PEOPLE WITH SAME PROBLEM. I ALSO FOUND A NHTSA RECALL 06083 FOR A 2001 YEAR MY VEHICLE IS A 2002. I TOOK THE VEHICLE TO THE CHEVROLET DEALER AND HAD THE CRANKCASE POSITION SENSOR REPLACED AND THAT SOLVED THE PROBLEM. TO ELABORATE ON THE PROBLEM IT DID OCCUR WHILE I WAS DRIVING DOWN THE HIGHWAY AT 65 MILES PER HOUR. THAT IS VERY SCARY AND AS THIS IS A TRUCK I COULD HAVE BEEN TOWING MY BOAT. I DO HAVE THE DEFECTIVE PART. IT SEEMS TO ME THAT ALL THE DEFECTIVE PARTS WERE NOT REMOVED FROM INVENTORY OR THE SOLUTION TO THE PROBLEM WAS INADEQUATE. *TR

THE CONTACT TOOK THE VEHICLE TO THE DEALER ON SEVERAL OCCASIONS AND THEY REPLACED THE ALTERNATOR, ON-BOARD ASSEMBLY IN THE COMPUTER SYSTEM, THROTTLE PLATE, AND REPROGRAMMED THE PCM. THE REMEDIES HAVE NOT CORRECTED THE FAILURES. THE FAILURE AND CURRENT MILEAGES WERE 138,000. UPDATED 07/24/09. *LJ

I OWN A 2002 CHEVROLET SILVERADO 2500 HD, 8.1 LITER, V8. IN THE PAST 4 MONTHS, THE VEHICLE COMPLETELY WOULD LOSE POWER AND SHUT OFF. AFTER A FEW MINUTES, THE VEHICLE WOULD RESTART. IT DID NOT MATTER THE SPEED OF THE VEHICLE, NOR DISTANCE DRIVEN. THERE WAS NO DASH BOARD LIGHTS ON INDICATING ANY PROBLEMS. I STALLED SEVERAL TIMES IN TRAFFIC, NEARLY MISSING/CAUSING ACCIDENTS. THE DEALER HAD VEHICLE FOR 3 DAYS AND SAID THERE WAS NOTHING ON DIAGNOSTIC SHOWING PROBLEMS. I REFUSED VEHICLE STATING I WAS NOT GOING TO ENDANGER MYSELF OR FAMILY TILL RESOLVED. IT WAS DETERMINED, AFTER THE GM BLOG AND PERSONAL INTERNET SEARCH OF THIS VEHICLE COMPLAINTS, THE CRANKSHAFT POSITION SENSOR WAS BAD. THE DEALER REPLACED FOR A CHARGE OF $288.38 PARTS/LABOR AT MY EXPENSE. THIS VEHICLE NEEDS A RECALL FOR THIS PART AND SOMEONE IS GOING TO BE SERIOUSLY HURT, ESPECIALLY WHEN THERE IS NO INDICATION OF A PROBLEM SHOWING. CASE #71-71437694 FILED WITH CHEVROLET AT 1-800-630-2438. *TR

2002 CHEVROLET 2500HD W/ 8.1L GASOLINE ENGINE: THE FAILURE OF THE CRANKSHAFT POSITION SENSOR ON THESE ENGINES APPEARS TO BE A VERY COMMON PROBLEM. THIS SENSOR FAILED ON MY TRUCK AT ONLY 30K MILES! I KNOW OF TWO OTHER '02 TRUCKS W/ THIS ENGINE THAT ALSO HAD THE SENSOR FAIL AND MANY OTHERS HAVE BEEN DISCOVERED WHILE DOING RESEARCH ON THIS PROBLEM! THE SERIOUSNESS OF THE PROBLEM LIES IN THE FACT THAT THE TRUCK SUDDENLY STOPS RUNNING FOR NO REASON AND YOU LOSE ALL POWER FOR THE BRAKES AND STEERING. AT TIMES IT WILL RESTART WITHOUT ANY PROBLEMS ONCE YOU SHIFT TO NEUTRAL, BUT OTHER TIMES IT MAY NOT RESTART FOR A DAY OR MORE. THIS WAS A HUGE SAFETY ISSUE FOR ME SINCE I TOW A 10K LBS. FIFTH-WHEEL WITH THE TRUCK! MY TRUCK STOPPED RUNNING FOUR TIMES OVER THE COURSE OF TWO WEEKS AS A RESULT OF THIS PROBLEM. EVERYTIME WAS WHILE TRAVELING IN TRAFFIC, WITH ONLY ONE OF THE TIMES WHILE BEING STOPPED AT A LIGHT! MY TRUCK IS NO LONGER UNDER WARRANTY DUE TO THE TIME LIMIT OF 36 MONTHS EXPIRING. TO HAVE SUCH A PART FAIL WITH ONLY 30K MILES ON THE ENGINE IS OUTRAGEOUS. ONE OF THE OTHER TRUCKS I KNOW OF HAD THE SENSOR FAIL AROUND 55K MILES. SAME PROBLEM, IT WOULD JUST STOP IN TRAFFIC OR WHEN PULLING OUT OF A LIGHT OR STOPPED TURN. AGAIN, A HUGE SAFETY ISSUE!!! THE COSTS TO ME TO REPAIR MY TRUCK FOLLOW: AC DELCO REPLACEMENT CRANKSHAFT SENSOR - $69.26 TOW CHARGES TO TOW TO JOSEPH CHEVROLET, CINCINNATI, OH - $58.85 LABOR DUE TO THE ORIGINAL SENSOR BREAKING IN THE BLOCK! - $336.54 TOTAL COST TO REPLACE THE SENSOR AFTER ONLY 30K MILES! = $464.65 AGAIN, I HAVE TO REPEAT HOW LARGE A SAFETY ISSUE THIS IS ON THESE TRUCKS!!! THE ENGINE JUST STOPS FOR NO REASON AT ANY TIME, HIGHWAY, SLOW MOVING, STOPPED, ETC. IT MAY RESTART, BUT THEN AGAIN IT MAY NOT FOR MANY HOURS! THE TRUCKS WITH THESE ENGINES IN THEM ARE GENERALLY TOWING LARGE TRAILERS BEHIND THEM. THIS COMPOUNDS THE SAFETY ASPECT OF THE PROBLEM. *JB

COMPLAINT REPORTS ALLEGE POOR WELD QUALITY AND/OR BENDING OF THE SUBJECT VEHICLE ORIGINAL EQUIPMENT TRAILER HITCH RECEIVER.THE AGENCY'S INVESTIGATION INCLUDED ANALYSIS OF MANUFACTURER AND AGENCY INCIDENT REPORTS, REVIEW OF POLICE REPORTS, ANALYSIS OF THE AGENCY'S FATAL ANALYSIS REPORTING SYSTEM, A VEHICLE OWNER SURVEY, INSPECTION OF TOW VEHICLES/HITCHES AND ANALYSIS OF FAILED PARTS.INCIDENTS OF WELD FAILURE WERE RARE AND ASSOCIATED WITH VERY LOW-SPEED DRIVING (TURNING, BACKING AND SUDDEN STOPPING).INCIDENTS OF BENDING WERE ASSOCIATED WITH IMPROPER TRAILER HITCH ADJUSTMENT OR OVERLOADING. A SAFETY-RELATED DEFECT HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES DOES NOT APPEAR TO BE WARRANTED.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.THE AGENCY WILL MONITOR THIS ISSUE AND RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.SEE DOCUMENT SEARCH FILE FOR ADDITION INFORMATION.
