2005 Chevrolet Trailblazer

DRIVING ON THE HIGHWAY TO THE SHORE MY SPEEDOMETER INCREASED TO 95 MPH. WHEN WE PARKED IT WAS STUCK ON 10. SINCE THEN IT HAS HAPPENED MANY TIMES. WHEN I PARK I HAVE TO CHECK WHAT IT STOPS AT. SOMETIMES, ITS 10, 20, 30, ETC. I HAVE TRIED DISCONNECTING THE NEGATIVE BATTERY CABLE AND THAT HELPS AS A TEMP FIX. MY DEALER SAYS THERE IS NO RECALL, BUT I SAW ONLINE A CLASS ACTION SUIT AGAINST GM, BUT NOT FOR TRAILBLAZERS. THIS IS A GM ISSUE AND I DON'T HAVE THE MONEY TO GET IT FIXED. UPDATED 03/11/14

I WAS DRIVING ON THE HIGHWAY WHEN I SLOWED DOWN & STOPPED FOR AN ACCIDENT AHEAD OF ME. I DID NOT SLAM ON MY BRAKES AND I DID NOT GO OVER ANY BUMPS THAT WOULD JAR THE VEHICLE. I WAS STOPPED FOR APPROXIMATELY 20 MINUTES. WHEN I BEGAN ACCELERATING I NOTICED THE SPEEDOMETER WAS NO LONGER ACCURATELY READING MY SPEED. I WAS DOING AROUND 50 MPH, BUT MY SPEEDOMETER WAS READING 22 MPH. I TRIED TURNING THE CAR OFF ONCE I GOT HOME, THEN RESTARTING IT, BUT IT WAS STILL READING 22 MPH. WHEN I DROVE IT THE NEXT DAY, IT STARTED OUT READING 10 MPH, AND HAS VARIED SINCE THEN, BUT STILL NOT READING ACCURATELY. *TR

I WENT INTO TOWN TO GRAB DINNER AND AS I AM DRIVING ALONG, MY HEADLIGHTS SHUT OFF. THE ONLY THING THAT REMAINED ON, WERE THE ORANGE TURN SIGNAL LIGHTS. I FRANTICALLY TURNED THE HEADLIGHT KNOB ON AN OFF AND NOTHING HAPPENED. I WAS LOOKING FOR A PLACE TO TURN OFF THE HIGHWAY, HOWEVER IT WAS NIGHT TIME AND I HAD NO HEADLIGHTS. I ENDED UP PULLING OVER TO THE GRAVEL SIDE OF THE ROAD, AND TURNED THE CAR OFF. NOW I AM STUCK ON THE SIDE OF THE HIGHWAY AT NIGHT TIME, WITH NO WORKING HEADLIGHTS. I TURNED THE CAR OFF AND GOT OUT, TAPPED THE HEADLIGHTS AND LOOKED FOR ANY PHYSICAL DAMAGE AND DID NOT FIND AN ANSWER. UPON STARTING THE CAR AGAIN, IT SOUNDED LIKE SOMEONE HAD TURNED ON A VACUUM CLEANER. THE NOISE PITCHED UP FOR ABOUT 5 SECONDS BEFORE PITCHING BACK DOWN. AFTER RE-STARTING THE OIL PRESSURE GAUGE MOVED FROM ITS NORMAL POSITION AT "12 O'CLOCK" TO AN ABNORMAL "6 O'CLOCK". I TRIED TO CALL ONSTAR FOR A VEHICLE DIAGNOSTIC, HOWEVER NOW MY RADIO WOULD NOT WORK EITHER. I TRIED THE HEADLIGHTS AGAIN, AND THEY STILL WOULD NOT TURN ON. I TURNED ON MY HIGH BEAMS, AND PROCEEDED BACK HOME. WHILE EN ROUTE MY SPEEDOMETER WAS READING 10MPH OVER MY ACTUAL SPEED. WHEN I PULLED INTO MY DRIVEWAY AND TURNED THE CAR OFF, THE SPEEDOMETER STAYED AT 10MPH. I FIND IT VERY HARD TO BELIEVE THAT ALL OF THESE THINGS HAPPENED ALL AT ONCE AS A COINCIDENCE. THIS IS A HUGE SAFETY CONCERN AS I LOST THE ABILITY TO SEE AT NIGHT, AS WELL AS THE ABILITY TO MONITOR MY SPEED ALL WHILE TRYING TO DRIVE. NOT TO MENTION ALL OF THE MOTORISTS WHO WERE BLINDED BY MY HIGH BEAMS ON THE WAY BACK. *TR

WHILE DRIVING MY VEHICLE, THE SPEEDOMETER STOPS WORKING. IT WORKS WHEN YOU START THE CAR, THEN WHEN STOPS ARE MADE, IT STOPS WORKING ALTOGETHER AND GOES TO ZERO. I HAVE RESEARCHED THE INTERNET, AND THIS IS A HUGE PROBLEM FOR THIS VEHICLE, AND GM SHOULD HAVE RECALLED THIS FAULTY PART YEARS AGO. WHEN I TOOK IT TO GET REPAIRED THE SERVICE PLACE SAID IT WAS A CLUSTER THAT WOULD COST OVER $500 TO GET FIXED. ONCE AGAIN, THIS IS A HUGE PROBLEM AND GM SHOULD TAKE CARE OF TS CUSTOMERS. *TR

BOUGHT THIS VEHICLE USED IN OCT 2010. NOT LONG THEREAFTER, NOTICED THE SPEEDOMETER WOULDN'T WORK ALL THE TIME - NORMALLY IT WORKS WHEN I FIRST START DRIVING BUT WHEN THE VEHICLE WARMS UP, IT STOPS WORKING ALL TOGETHER. I THINK IT'S A SAFETY ISSUE IF YOU DO NOT KNOW HOW FAST YOU ARE GOING. THE CRUISE CONTROL ALSO DOESN'T WORK ONCE IN A WHILE. MOST OF THE TIME IT DOES, BUT OCCASIONALLY I CAN'T GET IT TO GO ON AT ALL. *TR
