ABS AND TRACTION CONTROL LIGHTS ARE ILLUMINATED. SOMETIMES WHILE BRAKING, A WEIRD HYDRAULIC SOUND IS HEARD AND THE BRAKES DONT WANT TO STOP THE CAR. THE PEDAL WONT GO DOWN FURTHER UNLESS SOMETIMES YOU FORCE IT AND LOCK UP THE TIRES AND BRAKES. NO CODES ARE SHOWING FOR THE ABS OR TRACTION CONTROL. BEEN HAPPENING SPORADICALLY FOR A YEAR.
ON FEBRUARY 8, 2019, MY MOTHER WAS PULLING INTO A MAINTENANCE GARAGE TO GET AN OIL CHANGE. UPON PULLING INTO THE GARAGE, SHE WAS UNABLE TO STOP AND HER VEHICLE LUNGED FORWARD. AS A RESULT, HE VEHICLE HIT AN EMPLOYEE, WENT THROUGH THE MAINTENANCE GARAGE DOOR, THROUGH THE PARKING LOT, ACROSS A FOUR LANE STREET, AND EVENTUALLY STOPPED IN A FIELD ACROSS THE STREET FROM THE OIL CHANGE VENUE. THIS IS AN APPROXIMATE DISTANCE OF 300 FEET. UPON FURTHER REVIEW BY MY MECHANIC, IT WAS DISCOVERED THE ABS SYSTEM WAS MALFUNCTIONING CAUSING THE BRAKE PEDAL TO DROP IN THE CAR, AND THE CAR NOT TO STOP. THE WIRING HARNESS ALSO WAS CRACKED RESULTING IN A CUT TO THE ABS WIRE, CAUSING THE ABS MALFUNCTION RESULTING IN THE CAR TO NOT STOP, AND THE ELECTRICAL MALFUNCTION WHICH CAUSED THE CAR TO SPEED FORWARD. GENERAL MOTORS WAS NOTIFIED, BUT DENIED RESPONSIBILITY OF THIS CLAIM.
DRIVING DOWN MY FAMILIAR ROAD OF DUTCH HILLS OFF OF DR. 50. I TURNED MY WHEEL AT 27MPH. SLID OFF TOWARD THE EDGE OF THE ROAD. FISHTAILED, MAINTAINED COMPOSURE. THEN , BEGAN A FISHTAIL TO A 180-360 INTO A CONCRETED STEEL BEAMED MAILBOX. KNOCKING OUT MY DRIVERS LIGHT ASSEMBLY, FRONT FENDER, BUMPER, DISABLING THEHOODOF MY CAR, TILTING MY RADIATOR. NOTHING OFTHENIGHT SHOULD OF SKINNY TIRES,NOR MADEMEFAIL TO MAINTAIN MY VEHICLE.
SERVICE THEFT SYSTEM TRIPS ALMOST EVERY CYCLE OF DRIVING THE CAR HAS LEFT ME AND MY FAMILY STRANDED COUPLE OF TIMES AND DOESN'T LEAVE ANY CODES. GETS UP TO ABOUT 20-30 MPH AND DIES RIGHT AWAY KILLING THE CAR. PULL OVER CYCLE THE CAR A FEW TIMES AND SOMETIMES IT'LL WORK FINE AFTER THAT FEW A FEW MILES AND AND THEN DOES IT AGAIN. HAZARDOUS TO NOT ONLY ME AND MY FAMILY BUT ALSO TO OTHER PEOPLE ON THE ROADS WHEN IT DOES HAPPEN!

SYSTEM FAILURE APPEARS ON DASHBOARD LIGHTS FLICKER UNABLE TO CONTROL CAR ON HIGHWAY..NOW HOME AND NOW WILL NOT EVEN START A SAFETY HAZARD
WHILE DRIVING IN TOWN, MAKING A LEGAL U-TURN AT A SAFE SPEED, THE POWER STEERING FAILED MID-TURN AND THE CAR WAS VERY HARD TO CONTROL AND THE STEERING WHEEL JERKED VIOLENTLY. IT IS UNKNOWN WHAT CAUSED THE FAILURE, HOWEVER THERE IS A RECALL ON MY VEHICLE CONCERNING CATASTROPHIC STEERING FAILURE. THIS STEERING FAILURE WAS CAUSED BY FAULTY MANUFACTURING/ EQUIPMENT BY GM.
WHEN DRIVING HOME FROM WORK, I WAS IN THE CENTER LANE OF THE HIGHWAY, WHEN THERE WAS A LOSS OF POWER IN MY 04 GRAND PRIX, THE DISPLAY SHOWED "LOSS OF POWER TO THE ENGINE" THERE WERE TRUCKS ON EITHER SIDE, LUCKILY I WAS ABLE TO GET TO THE SIDE OF THE ROAD BY DODGING THE VEHICLES COMING UP BEHIND ME. I CALLED MY MECHANIC AND EXPLAIN THE CONDITION, HE KNEW EXACTLY WHAT WAS WRONG BECAUSE HE SAID HE FIXES THEM ALL THE TIME. THE SPEED SENSOR IN THE ACCELERATOR PEDAL LOSSES CONNECTION WITH THE THROTTLE BODY AND LOSS OF POWER IS THE RESULT. IF THIS SAME PROBLEM OCCURRED ON A TOYOTA THEY WOULD HAVE RECALLED THE VEHICLES AND FIXED THE PROBLEM. I GUESS GM HAS ENOUGH PROBLEMS OR MAYBE NOT ENOUGH PEOPLE HAVE DIED TO MAKE THIS A GM SAFETY PRIORITY.
WHILE DRIVING APPROXIMATELY 30 MILES PER HOUR, STEERING WHEEL BECAME TIGHT THEN LOCKED WHILE IN MOTION. I BRAKED IMMEDIATELY FOUGHT WHEEL TO PARK ON SIDE OF STREET, SAME TIME "CHARGING SYSTEM FAILURE" NOTIFICATION CAME ON. I PLUGGED DIAGNOSTIC READER NO CODES COME UP. CHECKED SERPENTINE BELT, VISUAL CHECK UNDERHOOD, NOTHING OUT OF PLACE. OIL CHANGE, TUNE UP AND MINOR WORK DONE RECENTLY HOWEVER, THIS ISSUE WAS SUDDEN AND CANNOT BE DETECTED. AFRAID FOR MY LIFE AS I REGULARLY TAKE HIGHWAY FOR TRAVEL. RECALLED FOR CODE 14574 LAST WEEK, WOULD REALLY APPRECIATE IF LOCAL MECHANIC"SIMMONS-ROCKWELL BIG FLATS N.Y. IS SCHEDULED TO REPAIR CODE 14574 TUESDAY DEC.29, AT 930AM WOULD APPRECIATE IF SAME MECHANIC COULD BE COMPENSATED TO DIAGNOSE PROBLEM. SAID MECHANIC DID REPAIR KEY CODE FOR OTHER RECALL AND ONLY GM DEALER IN TOWN.
THE COMPUTER SYSTEM ALL LAST YEAR HAD THE WRONG DATES COMPARED TO THE DAY OF WEEK IT WAS. WHEN I AM DRIVING SOMETIMES AND I COME TO A STOP MY CAR SLIDES ESPECIALLY IN RAIN AND SNOW. MY ABS LIGHT COMES UP ALMOST ALWAYS WHEN I'M DRIVING
I FIRST NOTICED THAT WHEN TURNING THERE WAS A GRINDING NOISE. I TOOK IT TO A SHOP AND WAS TOLD THE FRONT PASSENGER CONTROL ARM NEEDED REPLACED. I RECENTLY TOOK MY CAR TO THE DEALERSHIP FOR THE IGNITION SWITCH RECALL AND FOUND OUT THAT THE SPEED HARNESS NEEDS REPLACED AND THAT IS WHAT'S CAUSING THE LIGHT FOR ABS/TC TO BE SERVICED. I HAVE RESEARCHED BOTH OF THESE ISSUES WITH THIS SPECIFIC VEHICLE AND IT APPEARS TO BE A WIDESPREAD ISSUE. WHAT CONSTITUTES A RECALL?
MY TRAC CONTROL, AND ABS LIGHTS CAME ON RANDOMLY, THE CAR WON'T GO OVER 65, IT BARLEY STOPS AT TIMES, THE BRAKE PEDAL GOES TO THE FLOOR AT TIMES, MY WHEELS ALWAYS SPIN IN THE RAIN, AND MOST EMPORIA TOY IT'S MY EVERY DAY DRIVER I HAVE MY 3 YEAR OLD IN, SO PLEASE GET BACK TO ME ASAP, ALL THE WHEEL HUBS WHERE REPLACED AND THE CODES STILL DIDN'T CLEAR SO I KNOW IT'S A COMP ISSUE SO HELP ME THE BEST YOU CAN. -[XXX].

MANY PONTIAC GRAND PRIX OWNERS ARE HAVING PROBLEMS WITH THE FOLLOWING SENSORS. TRACTION CONTROL/STS/ABS LIGHTS COME ON INTERMITTENTLY OR STAY ON. AFTER DOING SOME RESEARCH THIS SEEMS TO BE A COMMON PROBLEM AND SERVICE DEALERS HAVE ACKNOWLEDGE THAT THIS IS A PROBLEM. HOW SAFE IS IT FOR OUR FAMILIES AND OURSELVES TO BE DRIVING CARS THAT DO THIS. *TR
I WAS STOPPED AT A LIGHT AND WHEN THE LIGHT TURNED GREEN I VEHICLE ACCELERATED AND THE PEDAL STUCK, AND I HIT THE BRAKES AND IT WON'T BUDGE. WHEN I WAS ACCELERATING I WAS ONLY TRYING TO GO ABOUT 45 MPH ,AND AT THE TIME WHEN THE PEDAL BEGAN TO STICK I WAS GOING 25-30 MPH, AND THEN AFTER THE PEDAL STUCK I WAS ACCELERATED AT OVER 70 MPH BY THE TIME I PULLED OVER. I STEPPED ON THE BRAKES AND IT SLOWED DOWN TO ABOUT 15 MPH. IT WAS STILL TRYING TO ACCELERATE , SO I PUT IT IN PARK AND CAR WAS STILL TRYING TO ACCELERATE..........RPM WAS AT 4, AND I WAS SITTING STILL, AND FOOT WASN'T ON THE BRAKE, ALMOST HIT SOMEONE. THIS WAS THE 3RD TIME THIS HAPPENED , BUT THIS TIME I ACTUALLY ALMOST GOT INTO A CAR ACCIDENT. CHECKED ON RECALLS , AND THEY SAID THAT THIS CAR WAS NOT LISTED AS BEING IN THE ACCELERATOR PEDAL"RECALL. I TOOK THE CAR TO A REPAIR SHOP , AND THEY STATED THAT IT NEEDED A NEW PEDAL. I STILL BELIEVE IT SHOULD BE UNDER THE ACCELERATOR PEDAL RECALL.*AK

CRUISE CONTROL FAILS TO ENGAGE OR EXHIBITS A DELAYED ENGAGEMENT. SETTING CRUISE CONTROL ON ONE SPEED AND SOMETIMES ENGAGES ON A SPEED 5MPH LOWER OR FAILS TO ENGAGE AT ALL.*AK
POSITION OF THE CRUISE CONTROL LEVER MAKES IT EASY TO ACCIDENTALLY DISENGAGE. WHEN USING THE DECEL FEATURE TO REDUCE SPEED BY 1 MPH, CAN UNKNOWINGLY MOVE THE LEVEL REARWARD SLIGHTLY, CAUSING CRUISE TO DISENGAGE.*AK
WHILE TURNING THE STEERING WHEEL THE DRIVER UNKNOWINGLY ENGAGED THE CRUISE CONTROL. THE CONSUMER CONTACTED THE DEALER WHO INDICATED THAT IS HOW THE VEHICLE IS DESIGNED. PLEASE PROVIDE ANY ADDITIONAL INFORMATION. *NM
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.
