2003 Chevrolet Trailblazer Speed Control & Cruise Problems

THE PROBLEM HAPPENS WHEN COMING TO A STOP THE ENGINE WILL SURGE OR JUMP AS MUCH AS 2000 RPM'S AND YOU REALLY HAVE TO BE ON THE BRAKE TO HOLD IT. GO TO NEUTRAL LET IT REV THEN IT WILL COME BACK TO NORMAL. THE LAST TIME WAS ON A SNOW PACKED INTERSECTION WITH TWO OTHER VEHICLES IN OPPOSITE DIRECTIONS. THE BAD THING IS YOU DON'T KNOW WHEN IT'S GOING TO DO IT. HAD IT TO SEVERAL GARAGES AND NOBODY CAN DUPLICATE IT AND IT SHOWS NO CODES. *TR

THE SPEEDOMETER HAS STOPPED WORKING AND I HAVE SEEN THIS ON A LOT OF CHEVYS BUT THE TRAILBLAZER IS NOT ON THE RECALL LIST. IT SHOULD BE!

I WAS DRIVING TO WORK WHEN ALL OF A SUDDEN I REALIZE THAT MY SPEED ODOMETER WASN'T WORKING AND I HAD TO PUSH THE BRAKES BECAUSE IT FELT THAT I WAS GOING TO FAST AND THE SPEED LIMIT WAS 35 HOWEVER MY SPEED ODOMETER WAS STUCK ON 10MPH.... BUT IT WAS PROBABLY GOING AT ABOUT 55 MPH... *TR

2003 CHEVY TRAILBLAZER EXT. SPEEDOMETER HAS MALFUNCTION CONTINUOUSLY FOR THE LAST 4 YEARS. VERY DANGEROUS. COMPANY (GM) SAYS IT IS NOT DANGEROUS AND THEY DO NOT HAVE ENOUGH COMPLAINTS. THOUSANDS ON THE INTERNET. *TR

1-15-11 MY 2003 TRAILBLAZER SPEEDOMETER STUCK ON 20MPH. AFTER A SHORT DRIVE, SHUT THE CAR OFF, ONCE STARTED IT WAS STUCK JUST BELOW 10 MPH. THE TEMPERATURE OUTSIDE TODAY IS 30 DEGREES. I AM THE ORIGINAL OWNER. I AM THE ORIGINAL OWNER. *TR

I PURCHASED A 2003 CHEVY TRAILBLAZER ONE YEAR AGO WITH 63K MILES. AT 85K MILES, THE SPEEDOMETER QUIT WORKING. MOST OFTEN, THE VEHICLE DEFECT OCCURS WHEN THE VEHICLE IS IN CRUISE CONTROL MODE. HOWEVER, ONCE CRUISE CONTROL IS TURNED OFF, THE DEFECT PERSISTS. EVEN WHEN THE CAR IS COMPLETELY TURNED OFF, WITH THE KEY REMOVED FROM THE IGNITION, THEN RESTARTED, THE DEFECT PERSISTS. THERE ARE TWO TYPES OF SITUATIONS WHEN THIS PROBLEM OCCURS: 1) THE SPEEDOMETER REGISTERS A SPEED, BUT IT IS ROUGHLY 15MPH LESS THAN THE VEHICLES ACTUAL SPEED. THIS, OF COURSE, IS QUITE DANGEROUS IF THE OWNER OF THE VEHICLE DOES NOT KNOW ABOUT THE DEFECT, FOR EXAMPLE, IF IT IS HAPPENING FOR THE FIRST TIME. IT CAN BE COSTLY TO THE POCKETBOOK, DRIVING RECORD, AND POTENTIALLY DEADLY. 2) THE CAR IS DRIVING, BUT THE SPEEDOMETER REGISTERS 0MPH. WHEN I FIRST NOTICED THE PROBLEM, I WAS DRIVING ON A HIGHWAY. I HAVE A GPS FEATURE THAT ALLOWS ME TO DETECT SPEED (THANKFULLY) AND ACCELERATED TO 80PMH FOR A BRIEF PERIOD OF TIME, BUT THE SPEEDOMETER STILL REGISTERED 0MPH. AFTER DOING SOME RESEARCH ON THE INTERNET, I REALIZED THIS WAS AN EXTREMELY COMMON PROBLEM, NOT JUST WITH CHEVY TRAILBLAZERS, BUT WITH A WHOLE HOST OF OTHER GM VEHICLES. ADDITIONALLY, THOSE MAKING REPORTS CLAIMED THEY HAD SOUGHT OTHER OUTLETS OF REPAIR, MANY OF THEM COSTLY, ALL OF THEM TO NO AVAIL. EACH CUSTOMER COMPLAINED THAT GM WAS IN NO WAY HELPFUL AND HAD NO INTENTION OF RECALLING VEHICLES, DESPITE THE FACT THAT THIS IS A COMMON AND DANGEROUS DEFECT. UPON FURTHER RESEARCH, I DISCOVERED THERE WAS A SMALL SETTLEMENT CONCERNING THE ISSUE, THUS SUGGESTING THAT GM ACKNOWLEDGES RESPONSIBILITY FOR THE DEFECT. HOWEVER, THE SETTLEMENT ONLY COVERS A SMALL NUMBER OF VEHICLES, AND TO DATE, NO RECALL HAS BEEN ISSUED FOR THIS PROBLEM. I HAVE PERSONALLY CONTACTED CHEVROLET AND AM AWAITING A REPLY. ADDITIONALLY, I PLAN TO TAKE MY VEHICLE INTO THE DEALERSHIP, BUT AS I AM IN THE MILITARY, I MUST WAIT UNTIL MY SCHEDULE ALLOWS. *TR

THE INSTRUMENT CLUSTER (GAUGES) ON MY VEHICLE ARE GOING OUT 1 BY 1. IT STARTED WITH THE RPM'S A COUPLE OF YEARS AGO. I HAD IT LOOKED AT BY A CHEVY DEALER AND WAS TOLD THAT THERE WAS NOTHING WRONG WITH THE VEHICLE AND THAT THE GAUGE WAS JUST OUT. IT COULD BE REPAIRED BUT IT WASN'T NECESSARY IF IT ISN'T CAUSING ANY PROBLEMS. SHORTLY AFTER ANOTHER WENT OUT IT WAS THE OIL. AT THIS POINT ONLY 2 ARE STILL WORKING AND I KNOW THEY WILL GO OUT AS WELL AND, THOSE TWO ARE THE SPEEDOMETER AND THE FUEL. I DO KNOW OF OTHER CHEVY TRAILBLAZER OWNERS THAT THEIR SPEEDOMETER HAS WENT OUT AND THAT IS A HUGE SAFETY ISSUE. CHEVY HAS DONE A RECALL ON OTHER SUV'S FOR THIS SAME PROBLEM BUT, WILL NOT DO A RECALL ON THE TRAILBLAZER. I WOULD JUST LIKE FOR THIS INFORMATION TO BE NOTED SO THAT EVENTUALLY CHEVY WILL TAKE RESPONSIBILITY FOR THIS ISSUE.

THE SPEEDOMETER IN MY 2003 TRAILBLAZER STARTED BECOMING VERY INACCURATE AND WOULD NOT PROPERLY SHOW HOW FAST I WAS GOING. IT WOULD EITHER STICK ON A NUMBER OR RANDOMLY MAX OUT AT 120+ MPH, EVEN WHEN JUST PARKED. TOOK IT TO THE DEALER TODAY AND THE COST TO FIX IS A SHADE UNDER $500. THE PROBLEM IS THE CLUSTER, WHICH IS A VERY COMMON PROBLEM APPARENTLY. *TR

2003 CHEVROLET TRAILBLAZER LT (MILEAGE: 52,200)- SPEEDOMETER FAILURE VEHICLE TAKEN TO DEALER. TOLD BY DEALER THIS IS COMMON FAILURE. MY VEHICLE IS OUT OF WARRANTY (3YR/36,000 MILES) [SUBSEQUENT YEARS WARRANTIES: 5YR/100,000 MILE] COST TO REPAIR $560. *JB

I OWN A 2003 CHEVY TRAILBLAZER. IT HAS JUST OVER 60,000 MILES. THE SPEEDOMETER STOPPED WORKING CORRECTLY A FEW DAYS AGO. THE SPEEDOMETER READS BETWEEN 85-120 MPH NO MATTER HOW FAST I AM DRIVING. I HAVE BEEN TOLD BY MY LOCAL CHEVY DEALER THAT IT WILL COST AROUND $400.00 TO HAVE THE SPEEDOMETER REPAIRED. I BELIEVE CHEVROLET SHOULD BE RESPONSIBLE FOR THE REPLACEMENT/REPAIR COSTS SINCE THIS IS A SAFETY ISSUE THAT NUMEROUS OTHER CHEVY TRUCK/SUV OWNERS HAVE ALSO EXPERIENCED. THEY SHOULD HAVE RECALLED THE SPEEDOMETERS ON THEIR SUVS/TRUCKS A LONG TIME AGO.*JB

DT*: THE CONTACT STATED THE SPEEDOMETER BECAME INOPERABLE, AND NEEDED TO BE REPLACED. THE SERVICE DEALER DETERMINED THE VEHICLE HAD TO BE SHIPPED OUT OF STATE TO HAVE THE SPEEDOMETER REPLACED.*AK

WHILE DRIVING, MY SPEEDOMETER STOPPED WORKING COMPLETELY. I HAVE HAD IT CHECKED BY BOTH A GM DEALER AND AN INDEPENDENT REPAIR SHOP. I WAS TOLD THE ENTIRE "CLUSTER" WOULD HAVE TO BE REPLACED. I WAS ALSO TOLD THAT THERE ARE MANY OF THESE PROBLEMS AND THAT THERE IS A 2-3 WEEK DELAY IN GETTING THE PART SHIPPED. I WAS ALSO TOLD IT WOULD COST ABOUT $400 TO GET IT FIXED. MY CAR IS A 2003 AND HAS ABOUT 81,000 MILES ON IT. A SPEEDOMETER IS NOT LIKE AN ALIGNMENT, WEAR AND TEAR ITEM, OR NEGLECT OF HAVING IT SERVICED. IT IS OBVIOUSLY A SAFETY CONCERN BECAUSE OF SPEED, THE INABILITY TO GET THE PART IN A TIMELY MANNER AND THE UNWILLINGNESS OF GM TO COVER THE REPAIR. *JB

DT: THE CONTACT STATED ODOMETER WAS INTERMITTENTLY INACCURATE. THE DEALER AND MANUFACTURER HAVE NOT BEEN CONTACTED. NO REPAIRS HAVE BEEN MADE.*AK

WHILE DRIVING, THE CONSUMER NOTICED THAT THE SPEEDOMETER WAS INOPERATIVE. THE CONSUMER COULD NOT TELL HOW FAST SHE WAS DRIVING. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION. THE CAUSE HAS NOT BEEN DETERMINED AT THIS TIME. PLEASE PROVIDE FURTHER DETAILS. *JB

WHILE DRIVING ANY SPEED SPEEDOMETER WOULD READ THE WRONG MILEAGE. CONSUMER WOULD NOT KNOW WHAT SPEED THEY WOULD BE GOING. DEALERSHIP WAS NOTIFIED, BUT DID NOT RESOLVE THE PROBLEM. *AK

THE THROTTLE SENSOR MALFUNCTION. AS A RESULT THE VEHICLE BECAME INOPERATIVE. PLEASE PROVIDE ADDITIONAL INFORMATION. *JB

JAN 7, 2004 AT STOP LIGHT TURNED RIGHT AND HAD MY FOOT TO THE FLOOR TRUCK NOT MOVING MORE THAN 10 MLS AN HOUR. SERVICE ENGINE LIGHT ON AND REDUCED ENGINE POWER ON. THE TRUCK WAS SERVICED THROTTLE SWITCH WAS CRACKED AND REPLACED. *AK JAN 14, 2004 I WARMED TRUCK FOR 10 MIN BEFORE PULLING OUT, DROVE FOR 15 MIN CAME TO STOP IN TRAFFIC TRUCK PUTTED STALLED. NO LIGHTS LIT UP ON DASH. IT STARTED UP BUT FELT HESITATION THE RPMS DIDNT SEEM TO LEVEL ON RETURN TO TRUCK I LET IT WARM 15 MIN AND GAVE IT A LITTLE GAS PUTTING THE TRUCK IN DRIVE IT PUTTED STALLED NO INDICATOR LIGHTS. IT STARTED UP AND WHEN PULLING OUT PUTTED THE RPMS DROPPED FEELING IT WAS GOING TO STALL I PUNCHED THE GAS IT CAUGHT. JAN 19 & JAN 20 DEALERSHIP 7AM AND LEFT MY TRUCK FOR SERVICE. I NOTICED THAT HEATER LEVELS 1, 2 HAD BLOWING. I RCD A CALL WAS TOLD THE FUEL INJECTOR REGULATOR HAD LEAK WOULD NEED TO BE REPLACED. TRUCK WAS HELD OVER NIGHT WOULDNT BE READY FOR PICK UP UNTIL NEXT AFTERNOON. ASKED IF WAS THE REASON FOR STALLING - SAID IT MAY BE THEY COULD NOT REENACT THE STALL  BUT A LEAK IN THAT PART MIGHT CAUSE STALL. JAN 21, 2004 ON START UP SERVICE 4WD LIGHT CAME ON. THE INDICATOR LIGHT ABOVE THE 4WD SWITCH WAS NOT LIT. I SHUT OFF AND OPENED DOOR THINKING IT MIGHT RE-UP COMPUTER. THE SERVICE LIGHT (YELLOW) WAS ON AND NO INDICATION OF WHAT I WAS IN. I CALLED DEALERSHIP WAS TOLD THAT I COULD DRIVE THE CAR AS LONG AS THE LIGHT WAS NOT RED. JAN 23, 2004 TRUCK DROPPED OFF FOR SERVICE - SPOKE W MGR OF MY CONCERN ABOUT THIS TRUCK . THIS WAS THE THIRD TIME IN FOR SERVICE IN AS MANY WEEKS. ASKED MGR IF THEY COULD RUN A DIAGNOSTIC TEST TO MAKE SURE IT WAS OKAY. I HAVE SAFETY CONCERNS ABOUT DRIVING IT ON THE HIGHWAY OR LONG DISTANCES. SERVICE COMPLETED; I WAS TOLD THAT THE TMC MODULE IN THE COMPUTER HAD TO BE RESET. I WAS NOT OFFERED A RENTAL EITHER OF THE OTHER TIMES I HAD THE TRUCK IN FOR SERVICE.

2003, CHEVROLET TRAILBLAZER. 4 SPEED AUTOMATIC TRANS. 4 WHEEL DRIVE. STANDARD LENGTH CHASIS. 6 CYLINDER ENGINE. PROBLEM EXPERIENCED; UPON ACCELERATION ONTO THE INTERSTATE HIGHWAY, THE ENGINE LOST POWER FOR APPX. 5 SECONDS. THE ACCELERATOR PEDAL REMAINED DEPRESSED, THE ENGINE RESUMED ACCELERATION AFTER THE TIME SPECIFIED. CREATED MUCH FEAR, SINCE INTERSTATE TRAFFIC SPEED LIMIT IS 70 MPH, AND CARS ON THE INTERSATE CAME UP ONTO THE BUMPER VERY QUICKLY. THIS IS THE ONLY OCCURENCE TO DATE. ALSO, GASOLINE FILLER NECK TOO NARROW, OR VENT HOSE CONSTRICTED? FREQUENT REFLUX OF GASOLINE DURING THE PROCESS OF FILLING. TAKES A CONSIDERABLE AMOUNT OF TIME TO "TOP THE TANK". SO MUCH TIME THAT, I HAVE YET TO BEEN ABLE TO "TOP" THE TANK. PROBLEM OCCURS AT EVERY PUMP, NOT INDIGENOUS TO THE GAS PUMP, APPEARS INHERENT TO THE VEHICLE.*AK

WHEN DEPRESSING ACCELERATOR PEDAL TO MOVE FORWARD THE VEHICLE HESITATES AND LOSES POWER REGARDLESS OF SURFACE LEVEL, INCLINED OR DECLINED.*AK
