CHEVY REPLACED THE BURB FUEL SENSOR TWICE, AND THE TRUCK ONCE...UNDER WARRANTY. PAST WARRANTY THEY WILL NOT HELP. SAFETY ISSUE: I RAN OUT OF GAS IN DOWNTOWN ATLANTA INTERSTATE TRAFFIC DURING RUSH HOUR, HAD TO WEAVE MY DEAD TRUCK THROUGH 70 MPH TRAFFIC TO THE LEFT SHOULDER. VERY DANGEROUS MOVE...LUCKILY WAS NOT REAR-ENDED! HAVE FRIENDS W/ SAME TRUCK...SAME PROBLEM. *NM

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

I HAVE A 2002 CHEVROLET 2500 4X4. I NOTICED THE REAR BRAKES WERE GETTING VERY HOT. I PULLED THE REAR WHEELS AND NOTICED THE ROTORS HAD RUST PITS IN THEM WHICH I BELIEVE CAUSED THE BRAKE PADS TO WEAR PREMATURELY. THE FRONT PADS AND ROTORS ARE FINE. I HAD THE REAR ROTORS MACHINED AND REPLACED THE BRAKE PADS. *NM

I OWN A 2002 CHEV K2500HD. I HAVE HAD SEVERAL PROBLEMS, BUT WAS UNAWARE OF THIS SITE TO REPORT THESE PROBLEMS UNTIL NOW. FIRST, THE DRYER SWITCH ON THE AC WENT BAD @ 34K. SECOND,@ 65K I HAD TO REPLACE THE FRONT LEFT WHEEL HUB ASSEMBLY AS TALKED ABOUT IN ONE OF THE OTHER COMPLAINTS I READ. THIRD, @ 95K MY TRANSFER CASE DEVELOPED A LEAK AND I LOST ALL THE FLUID. A CHEVROLET MECHANIC SHOWED ME A TRANSFER CASE THAT HAD GONE BAD DUE TO THE SAME PROBLEM AND HAD BEEN USED IN 4WD W/OUT FLUID IN IT. ANOTHER CHEVROLET MECHANIC TOLD ME HE HAD SEEN SEVERAL OF THESE AND THAT "JB WELD IS YOUR FRIEND". SO I PATCHED THE HOLE, AND 10K LATER IT DEVELOPED A SECOND LEAK IN A SIMILAR LOCATION AND ALSO ABOUT THIS SAME TIME AN ELECTRICAL PART (ABOUT $550) WENT OUT FOR MY 4WD. NOW AT 130K IT HAS DEVELOPED A THIRD LEAK! ALSO STARTING @ APPROXIMATELY 50K, MY REAR DIFFERENTIAL HAS LOCKED UP ON ME SEVERAL TIMES AND I HAVE HAD TO REPLACE 4 CABLES ON MY TAILGATE. AFTER BEING A CHEVY MAN ALL MY LIFE I THINK I WILL LOOK AT TOYOTA. *NM

DT: THE BRAKE ROTORS PITTED, CORRODED, RUSTED, AND FLAKED. THE BRAKES HAVE BEEN SERVICED, AND THE MECHANIC SAID THAT OTHER ROTORS HAVE BEEN CORRODING AS WELL. THE ROTORS DON'T SHOW SIGNS OF A PROBLEM UNTIL THE METAL HAS WORN DOWN. THE CONSUMER CONTACTED GENERAL MOTOR AND SAID THE WERE VERY RUDE.*AK

DEALERS WILL INSTALL A LOW-FORCE SPRING CLIP RETAINER FOR VEHICLES EQUIPPED WITH A PBR PARKING BRAKE SYSTEM. THE DEALER WOULD ONLY REPLACE THE RETAINER CLIP BUT STATES I WOULD HAVE TO PAY FOR THE EMERGENCY BRAKE SHOES. I FEEL GM SHOULD PAY FOR THE BRAKE SHOES SINCE THE RETAINING CLIP 'CAUSED THE PROBLEM.
