I've had the brakes replaced because I thought they were an issue I was having with my ABS. But my car will randomly lock its brakes as I'm driving, no matter what speed. I'm scared to drive it. It also almost loses all power after breaking but then speeds up on its own making it almost impossible to slow down or brake.
Speedometer and rms needles do not function.
THE FIRST THING TO GO WRONG WAS THE POWER WINDOWS DON'T WORK PROPERLY IN THE WINTER, NOW THE AIR CONDITIONER ONLY BLOWS COLD AIR INTERMITTENTLY, AND THE MOST RECENT PROBLEM IS THE HEADLIGHTS WON'T WORK AT ALL, I CALLED THE LOCAL SERVICE CENTER AND THEY SAID THAT THE ELECTRICAL RECALLS WERE VIN SPECIFIC, EVEN THO I HAD THE CORRECT MAKE MODEL AND YEAR MY VIN DID NOT QUALIFY FOR THE RECALL! I'M VERY UPSET THAT THEY CAN BE VIN SPECIFIC BUT I'M HAVING ALL THE ISSUES ON THE RECALLS!! I CAN NO LONGER DRIVE MY VEHICLE IF IT IS RAINING, FOGGY, OR DARK BECAUSE I HAVE NO HEADLIGHTS!!! I ALSO LOST CONTROL OF MY CAR IN THE RAIN AND THINK IT HAS TO DO WITH THE STABILITRAK, THE LIGHT HAS BEEN ON FOR A WHILE, LUCKILY I STOPPED MY CAR BEFORE I CRASHED INTO ANYTHING
WHILE DRIVING THE WHEEL JERKED TO LEFT. I CROSSING LAKE BRIDGE..I WONDER WHAT WAS THAT. THEN IT WAS LIKE I HAD 2 FLAT TIRES ON FRONT.. I SLOWED DOWN. JUST TO GET ACROSS BRIDGE TO PULL OVER.. IT STARTED DRIVING NORMAL. SO IT WASN'T TIRES. THEN STARTED AGAIN. SO GOT IT BACK HOME. THINKING IT TI RODS SWAY BAR, ETC. GOT ALL NEW FRONT END PARTS. NOW STEERING WHEEL JUSTS SPINS. NOW TOLD RACK AND PINION. MY CAR BEEN SITTING FOR 2 MONTHS TRYING FIGURE OUT WHAT COULD BE ISSUE.
I HAVE HAD MY SUV SINCE 2011 HAVE HAD NO PROBLEMS WITH IT UNTIL ABOUT FEB. 25,2019. I HAD MY BRAKES REPLACED FTONT AND BACK ALONG WITH THE ROTORS. A WEEK AFTER THAT I WAS DRIVING ON THE HIGHWAY COME UP TO A RED LIGHT WAS SLOWING DOWN AND WHEN I GOT TO 10 MPH IT STARTED TO PAULSATE AND WASN'T FOR SURE IF I WAS GOING TO STOP COMPLETELY. I FINALLY DID. I TOOK IT BACK TO MY MECHANIC HE CHECKED THE ABS TO SEE IF THE WHEELS WERE SPINNING AT THE SAME SPEED AND THEY WERE. WHEN I GO DOWN MY DRIVEWAY WHICK IS A HILL I'M NOT FOR SURE IF IT'S GOING TO FULLY STOP OR GO ON OUT IN THE ROAD, WE ARE ON A BLIND CURVE AND IT'S RATHER SCARING. ALSO I HAVE A PROBLEM WITH THE STABLILITY AND TRACK LIGHT COMING ON AND STAYING ON, I JUST RESTART MY SUV AGAIN FOR IT TO GO OFF. IT'S BOTH OF THE LIGHTS ON THE TRACK AND STABLITITY. MY DRIVER SIDE SEAT BELT IS FRILLY ON ONE SIDE AND GETTING THINNER.
TRUCK FAILED TO ACCELERATOR PEDAL DEPRESSED, ACTIVATING STABITRAK CONTROL.. HAD TO ACCELERATE THE PEDAL SEVERAL TIMES BEFORE THE TRUCK ACCELERATE ANS REACTED..HAD TO TAKE OFF STABILTRAK TO DRIVE THE TRUCK. CHANGED CHANGED HUBS AND SEVERAL SENSORS. GETTING NO CODES..TOOK IT TO SEVERAL SERVICE STATIONS INCLUDING THE CHEVY DEALERS AND GOT NO ANSWERS BUT TO WANT TO CHARGE ME FOR REPAIRS NOT NEEDED..I LOVE MY TRUCK DON'T WANT TO GET RID OF IT.
ELECTRICAL WIRING DOES NOT WORK CAUSING OTHER FUNCTIONS OF THE CAR TO NOT WORK.
THE DRIVER SIDE DOOR ELECTRICAL PANEL MALFUNCTIONS AND THE DOOR DOES NOT OPEN AND THE WINDOW DOES NOT GO DOWN AND THE WINDOW LOCK UNLOCKS AFTER BEING LOCKED. THE RACK AND PINION HAD TO BE REPLACED TWICE. THE CAR TURNED OFF WHILE DRIVING. THE LIGHT IN THE BACK WILL NOT WORK NO MATTER HOW MANY TIMES THE BULB AND RACK HAS BEEN REPLACED.
TAKATA RECALL THE STABILLTRAK LIGHT COME ON ALL THE TIME 2-3 TIME A DAY. I HAVE REPLACE THE WHEEL SENSOR, STEERING WHEEL SENSOR, NEW CABLE GOING TO THE WHEELS. EVER DAY IT COME ON AND WHEN I WAS GOING DOWN THE HIGH WAY AT 60-65 MILES THE LIGHT WILL COME ON. IT WILL STAY ON TILL YOU TURN THE SWITCH OFF.
VEHICLE SWAYS FROM SIDE TO SIDE WHEN SLOWING DOWN AND BRAKING
WAS DRIVING AT NIGHT AND ANOTHER VECHILE BESIDE ME TOLD ME I HAD NO LIGHTS.THE LOW BEAMS AREN'T WORKING,THE HIGH BEAMS ARE FINE.I WAS IN MOTION AT THE TIME.BUT STOPPED AT A RED LIGHT.I WAS ON A CITY STREET,GOING STRAIGHT.
THIS ISSUE OCCURRED ABOUT 6-7 TIMES THROUGHOUT MY 15 MILE TRIP. MY TRAVEL WAS ON A HIGHWAY AND SPEEDS WERE BETWEEN 55-68 M.P.H. AT THE ONSET OF EACH OCCURRENCE. I WOULD HIT A BUMP IN THE ROAD (NOT A MAJOR ONE ' JUST A BUMP) AND THEN THE 'STABILITRAK ACTIVE' LIGHT WOULD BE ILLUMINATED IN THE DASH CONTINUOUSLY BLINKING LIKE IT'S STUCK. THEN: -THE TRUCK WOULD BECOME SLUGGISH DROPPING SPEED AND KNOCKING OFF THE CRUISE CONTROL -YOU CAN'T ACCELERATE -THE STEERING LOCKS UP SORT OF CAUSING IT TO FEEL LIKE THE TRUCK IS OUT OF CONTROL, THIS OCCURRING AT HIGHWAY SPEEDS -THE AMOUNT OF POWER USED BY STABILITRAK WAS IMMENSE ' THE HEADLIGHTS BEGAN TO DIM THE LONGER IT WAS STUCK IN THIS STATE -IF YOU TRY BRAKING DURING THESE SPELLS IT HAS THE ANTI-LOCK ACTIVE SO YOU'RE JUST GRINDING AWAY LIKE YOU'RE IN A SKID BUT NOT STOPPING (AND THIS IS ON DRY PAVEMENT!) -- THIS OCCURRED ONE TIME WHILE I WAS ON AN EXIT RAMP AND AND I WAS UNABLE TO SLOW THANKFULLY I HAD TAKEN THE RAMP A LITTLE SLOWER TO BEGIN WITH OR I COULD HAVE BEEN IN MAJOR TROUBLE IN THE CURVE THEN SUDDENLY AS QUICK AS IT ALL STARTED IT RELEASES ' THE LIGHT SHUTS OFF AND ALL RETURNS TO NORMAL.
THERE IS TIME THE KEY WILL KEEP TURN ENGINE OVER EVEN WHEN YOU LET GO OF KEY , #2 HEADLAMP AND DAYTIME DRIVING LITE SOMETIMES WON'T WON'T WORK PROPERLY. AND THE LAST THING IS MY DRIVER SIDE MASTER DOESN'T WORK PROPERLY WHEN IT RAIN.
THE IGNITION WILL NOT TURN OFF UNLESS THE BRIGHT LIGHTS ARE ON. AT TIMES, IT WILL START AUTOMATICALLY EVEN WHEN THE IGNITION SWITCH IS TURNED OFF. SOMETIMES THE IGNITION WILL NOT TURN ON OR OFF AT ALL. FUEL SYSTEM IS FAULTY. CONSISTENTLY PROBLEMS HAVE CAUSED THE FUEL PUMP TO GO OUT REPEATEDLY, AND THE FUEL GAUGE TO STOP WORKING. MOTOR IN THE DRIVERS SEAT STOPPED WORKING AFTER MONTHS OF PROBLEMS. THE RADIO HAS STOPPED WORKING. WE'VE REPLACED THE FUSE, AND HAVE BEEN TOLD ITS AN ELECTRICAL PROBLEM.
TL* THE CONTACT OWNS A 2007 CHEVROLET TRAILBLAZER. THE CONTACT STATED WHILE DRIVING APPROXIMATELY 40 MPH, THE ENTIRE INSTRUMENT PANEL ILLUMINATED AND THE VEHICLE SUDDENDLY ACCELERATED. THE CONTACT MENTIONED THAT THE FAILURE RECURRED SEVERAL TIMES. THE VEHICLE WAS TAKEN TO THE DEALER WHO REPAIRED THE VEHICLE HOWEVER, THE REPLACEMENT PARTS WERE UNKNOWN. THE REPAIR FAILED TO REMEDY THE ISSUE. THE MANUFACTURER WAS NOT MADE AWARE OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 75,000.
ON JULY 18TH GOLDSBORO CHEVROLET IN NC WE WERE TOLD COULD NOT SEAL THAT LEAK, BECAUSE IT WAS TO FAR GONE. SO HE HAD TO ORDER PART FOR IT, WE SET A DATE TO BRING BACK TRUCK ON JULY 23 2013. THEN WE WAS TOLD THEY WAS GOING TO USE A SEALANT KIT THAT HE WAS THINKING WE NEED WHOLE PART BUT THEN HE CHANGE HIS MIND THAT IT WAS NOT NEEDED. WE ARE CONFUSE ABOUT IT, BECAUSE THE CIRCUIT BOARD HAS A MIND OF IT ON. SO WE DO NOT WANT PATCH WORK WE WANT A NEW UNIT, CAN SOMEONE PLEASE RESPOND BACK TO ME TELLING US OUR RIGHTS, AND WHAT TO DO . *TR
THE FUEL GAUGE ON MY 2007 CHEVY TRAILBLAZER BEGAN FLUCTUATING FROM PROPER FUEL LEVEL READING TO EMPTY AT AROUND 74,000 MILES. AFTER FEW WEEKS OF THIS, THE FUEL GAUGE NOW CONSISTENTLY READS EMPTY AFTER DRIVING 115 - 120 MILES ON A FULL TANK, WHICH INDICATES A FAILURE OF THE FUEL SENSING UNIT. I AM DRIVING THE VEHICLE BASED ON THE TRIP ODOMETER AND I HAVE RUN OUT OF GAS TWICE SINCE THIS IS NOT A RELIABLE WAY TO ESTIMATE THE AMOUNT OF FUEL IN THE TANK. BOTH TIMES I WAS ON MY WAY TO WORK A ON HEAVILY TRAVELED BRIDGE WITH NO SHOULDER. THIS IS A HUGE SAFETY HAZARD!!! ALSO AT AROUND 75,000 MILES THE DRIVER SIDE DOOR LOCK STOPPED WORKING AND THE ELECTRONIC STABILITY CONTROL OFF LIGHT AND ELECTRONIC STABILITY CONTROL MAINTENANCE LIGHT PERIODICALLY TURN ON. *JS
FUEL GAUGE STARTED FLUCTUATING BETWEEN FULL AND EMPTY, NOW IT JUST STAYS ON EMPTY. 09-09-2011 WITH CAR IN PARK THE IDLE SOMETIMES GOES UP TO 2100 RPMS THEN WILL GO AS LOW AS 600 RPMS, RECENTLY AS OF 09-16-2011 I HAVE BEEN NOTICING A FLUCTUATION IN SPEED ON ITS OWN OR WITHOUT MY ASSISTANCE. *TR
TL* THE CONTACT OWNS A 2007 CHEVROLET TRAILBLAZER. THE CONTACT STATED THAT THE DRIVER WAS TRAVELING AT AN UNKNOWN SPEED WHEN THE VEHICLE ABNORMALLY ACCELERATED AND CRASHED INTO A CONCRETE WALL. THERE WERE FOUR OCCUPANTS IN THE VEHICLE, ALL OF WHICH WERE KILLED. A POLICE REPORT WAS FILED. THE BLACK BOX WAS INVESTIGATED AND THE INVESTIGATING OFFICER DETERMINED THAT VEHICLE ACCELERATED BUT THE DRIVER DID NOT APPLY THE BRAKES DURING THE FAILURE. THE CONTACT STATED THAT THERE WERE BLACK TIRE MARKS AT THE SCENE OF THE CRASH, INDICATING THAT THE BRAKES WERE DEPRESSED. THE CONTACT DISCOVERED NUMEROUS COMPLAINTS ONLINE REGARDING THE SAME ACCELERATION FAILURE FOR THE YEAR, MAKE AND MODEL VEHICLE. THE CONTACT STATED THAT HE DID NOT BELIEVE THAT THE DRIVER WOULD HAVE DRIVEN AND CRASHED INTO A CONCRETE WALL WITHOUT THERE BEING A VEHICLE MALFUNCTION. THE FAILURE MILEAGE WAS 65,000.
THIS VEHICLE HAS HAD A NUMBER OF ELECTRICAL AND /OR COMPUTER PROBLEMS. THE FIRST SET OF TIRES ON THE VEHICLE WERE WORN OUT BECAUSE THE COMPUTER WOULD SAY THEY HAD LOW PRESSURE, SO WE WOULD FILL THEM AND CHECK THEM WITH THE ONBOARD TIRE PRESSURE, OTHERWISE IT WOULD CONTINUE TO SAY THE TIRES WERE LOW. THE GAS GAUGE GOES FROM FULL TO EMPTY AND BACK AT LEAST 10 TIMES A DAY, THEY SAY AT THE SERVICE DEPT IT'S THE FUEL SENDING SWITCH. SERVICE STABILITRAC WARNING COMES ON AT VARIOUS TIMES. I THINK ALL WARNINGS (LIGHTS AND THROUGH THE COMPUTER SCREEN) HAVE COME ON AT LEAST ONE TIME, SOME WE HAD TO STOP THE CAR AND LOOK UP WHAT THE LIGHT WAS IN THE BOOK. NOW THE IGNITION SWITCH HAS SOMETHING WRONG, THE STEERING WHEEL WILL NOT LOCK WHEN THE CAR IS SHUT OFF AND THE KEY IS REMOVED. THEN THE CAR WON'T START UNLESS YOU WORK THE KEY AND THE SWITCH. TODAY IT STARTED AND THEN QUIT WHEN YOU LET GO OF THE KEY AND IT GOES TO THE RUN POSITION. WHEN YOU TURN THE KEY ON, THERE IS WEIRD NOISE LIKE ELECTRICAL SHORT OR SOMETHING. THERE HAVE BEEN PROBLEMS WITH WINDOW SWITCHES AND REGULATORS.
I PURCHASED A BRAND NEW CHEVROLET TRAILBLAZER AT THE END OF 2007. SINCE THEN, I HAVE HAD MULTIPLE SERVICE ISSUES WITH THE CAR, MOST NOTABLY A FAULTY FRONT AXLE THAT HAD TO BE REPLACED. IN JANUARY 2009, MY SERVICE 4WD LIGHT CAME ON AND I COULD NOT PUT MY CAR INTO 4WD. I IMMEDIATELY TOOK MY CAR TO THE DEALERSHIP, WHO COULD NOT FIND A PROBLEM AND RETURNED MY CAR TO ME. A WEEK LATER, I WAS DRIVING MY CAR IN THE SNOW IN 4WD, GETTING READY TO ENTER THE HIGHWAY, WHEN THE CAR STALLED AND THE SERVICE 4WD LIGHT CAME ON AGAIN. I RETURNED TO THE DEALERSHIP, WHO KEPT MY CAR FOR 3 DAYS AND AGAIN COULD NOT FIND THE PROBLEM. THEY RETURNED MY CAR TO ME AND SAID "YOU PROBABLY GOT SNOW IN YOUR MUFFLER". I DROVE MY CAR IN 4WD PERIODICALLY FOR THE NEXT 19 MONTHS TRUSTING THAT MY CAR WAS SAFE. WHEN THE SAME PROBLEM HAPPENED AGAIN AT THE END OF NOV 2010, I TOOK MY CAR TO A DIFFERENT DEALERSHIP WHO TOLD ME I HAD A BAD FRONT AXLE AND 5 BAD GEARS THAT WERE BINDING, AND THAT I COULD NOT DRIVE MY CAR IN 4WD UNTIL THIS WAS REPAIRED. I HAVE ALSO HAD TO HAVE AN O2 SENSOR REPLACED, SEVERAL BODY SYSTEM REPAIRS, AND YESTERDAY MY SERVICE STABILITRACK LIGHT CAME ON AND STAYED ON UNTIL I RESTARTED THE CAR. I HAVE ASKED CHEVY TO BUY BACK MY CAR, AS IT IS CLEAR I HAVE A POORLY MANUFACTURED AND UNSAFE VEHICLE, AND THEY HAVE ONLY OFFERED TO COVER MY BODY SYSTEMS PARTS UNDER WARRANTY. I FEEL UNSAFE IN MY CAR AND I DON' T KNOW WHERE TO TURN FOR HELP. *TR
DRIVING 40 MPH IN CITY TRAFFIC, APPROACHING STOPPED TRAFFIC. BRAKES START TO LOCK UP. WHILE COMPLETELY STOPPED THE BRAKES ARE LOCKED, THE PEDAL WILL NOT COMPRESS. WHEN APPLY GAS, THE CAR DOES NOT GO FORWARD. I HAD TO PUT THE CAR IN PARK, TURN OFF THE CAR, AND THEN START IT AND PUT BACK INTO DRIVE FOR IT TO WORK. *TR
2WD 2007 TRAILBLAZER SUPER SPORT GOES WIDE OPEN THROTTLE AFTER START UP AND SELECTING REVERSE. THIS IS WITH FOOT ON BRAKE TO SHIFT AND NO THROTTLE APPLIED OR TOUCHED SINCE START UP. VEHICLE WAS IN A PARKING LOT. ENGINE WENT FULL THROTTLE AND SMOKED REAR WHEELS JUST AFTER SELECTING REVERSE. THIS DRAGGED THE FRONT WHEELS BACKWARDS A SHORT DISTANCE WITH THE FRONT BRAKES LOCKED UP. SHIFTING TO NEUTRAL HAD THE ENGINE GO OVER THE 6500 RPM REDLINE IGNORING ALL PCM PROGRAMMED REV LIMITERS. (REV LIMITERS: 4000 RPM IN NEUTRAL AND 6500 RPM IN GEAR.) DEALER FOUND DTC U1017 LOSS OF SERIAL COMMUNICATIONS FOR CLASS 2 DEVICES. I KNOW OF 4 OTHER 2007 TRAILBLAZER SUPER SPORT THAT HAVE RANDOMLY GONE WIDE OPEN THROTTLE. THIS IS AN ADDITIONAL PROBLEM SINCE COMPLAINT NUMBER : 10269455 THROTTLE HANG UP - NOT ALWAYS RETURNING TO IDLE POWER. *TR
FILLED MY TANK AND DROVE AWAY THE MORNING OF THE INCIDENT. WHILE DRIVING LATER THAT DAY MY FUEL GAUGE STARTED GOING DOWN WHILE DRIVING. IT WENT TO EMPTY THE LOW GAS INDICATOR LIGHT CAME ON AND IT STAYED THAT WAY FOR A FEW MINUTES BEFORE RETURNING TO FULL. THIS ONLY HAPPENED 1X SO FAR RECENTLY. I'VE ALSO HAD PROBLEM WITH ALL THE GAUGES GOING OUT WHILE DRIVING. SPEEDOMETER/FUEL/ ELECTRICAL/TACH ETC. HAD TO TURN OFF THE VEHICLE AND RESTART TO RESET THESE FUNCTIONS IN THE PAST. 2-3X AN HAD ONSTAR RUN DIAGNOSTICS. THE ELECTRIC STABILITY CONTROL HAS ALSO BEEN COMING ON/OFF INTERMITTENTLY QUITE FREQUENTLY AT STARTUP AND AT OTHER TIMES WHILE DRIVING. I'VE SEEN SIMILAR COMPLAINTS ON CHAT BOARDS BUT FEW HAVE TAKE THE STEPS TO DOCUMENT THEM BEYOND THE POSTINGS. THERE ARE MANY SIMILAR COMPLAINTS ON THE WEB. THANK YOU *TR
CHECK ENGINE LIGHTSTARTED COMING ON, THEN THE STABIL-TRAX AND THE ENGINE DECELERATION LIGHT STARTED COMING ON. WHEN THIS STARTED, THE ENGINE WOULD SHUT DOWN EVERY TIME THE LIGHTS CAME ON.AT FIRST IT WAS AT INTERVALS OF 40 TO 140 MILES. WHENEVER THE ENGINE FIRST STARTED THIS, YOU COULD SHUT THE IGNITION OFF FOR 1-2 MIN. , THEN THE VEHICLE COULD BE STARTED AND DRIVEN UNTIL THE LIGHTS CAME ON. DOTSON CHEVROLET, IN BIG SONNE GAP, VA. ( WHERE WE BOUGHT VEHICLE), HAS HAD THE VEHICLE OFF AND ON FOR 6 WEEKS. THEY HAVE CHANGED THE SENDING UNIT IN THE FUEL TANK, AND THE PCM MODULE ON THE ENGINE SO FAR. AS OF TODAY, 10-19-09 THE VEHICLE IS NOW SHUTTING DOWN AT 8-10 MILES. THEY SAY THEY ARE STILL CHECKING , BUT NOW THEY ARE THINKING THE PROBLEM MAY BE IN THE WIRING. SO FAR, WE HAVE LUCKILY BEEN DRIVING IN LIGHT TRAFFIC, WHERE WE WERE ABLE TO GET OUT TRAFFIC TO THE SIDE OF THE ROAD, WITHOUT ANY PROBLEM. IF THIS PROBLEM OCCURS ON THE INTERSTATE OF IN HEAVY TRAFFIC , IT COULD CAUSE A SERIOUS ACCIDENT. THE DEALER SAYS THE HAVE BEEN IN CONTACT WITH GM ABOUT THE PROBLEM. I WOULD HAVE THOUGHT THAT GM WOULD HAVE TECH PEOPLE, OF ENGINEERS THAT WOULD KNOW WHY THE CODES AND LIGHTS DON'T CORRESPOND WHEN THIS OCCURS, OR WOULD HAVE SOME IDEA WHAT MIGHT CAUSE SUCH A PROBLEM. *TR
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
