MY POWER STEERING WENT OUT AND WHEN YOU TRY TO GO OVER 40 THE CAR LUNGES FORWARD AND HAS A HARD TIME SHIFTING AND WILL CONTINUE WHILE IN CRUISE CONTROL. I ALREADY HAD WORK DONE ON THE FUEL LINE CAUSE THE LINE WAS CLOGGED AND THE VEHICLE WOULD LUNGE FORWARD CAUSE THE FUEL WASN'T GETTING PUSHED THROUGH. MY POWER STEERING WENT OUT AFTER MY BOYFRIEND PARKED IT. HE ONLY NOTICED IT WHEN HE TRIED DRIVING AWAY AND HE COULDN'T TURN THE WHEEL LIKE USUAL. THE CRUISE CONTROL DOES ITS THING WHILE IN MOTION. ALSO THE HEADLAMPS! THE BRIGHTS STAY ON, YOU HAVE TO HOLD THE DIMMER SWITCH BACK TO GET THE BRIGHTS TO TURN OFF BUT IF YOU LET GO OF THE SWITCH THEY TURN ON AND FLASH PEOPLE. IT ONLY TURNS OFF WHEN TURNING LEFT. THE AC COMPRESSOR BLEW TOO. I HAD BOUGHT THE VEHICLE 3 YEARS AGO DURING THE WINTER SO IT WAS BLOWING COLD AIR, BUT WHEN SUMMER HIT IS WHEN I NOTICED IT WAS ONLY BLOWING AIR FROM OUTSIDE INTO THE CAB. THE HEATER WORKS, BUT THE AC DOESN'T. MY BOYFRIEND WAS DRIVING HOME RECENTLY AND COULDN'T MOVE THE STEERING WHEEL AND ALMOST HAD A HEAD ON COLLISION BECAUSE OF THE POWER STEERING. THE POWER STEERING HAPPENED IN TOWN AT HIS PLACE OF WORK AND HAD TO DRIVE ON THE HIGHWAY TO COME HOME. THE CRUISE HAPPENS ON THE HIGHWAY. THE HEADLAMPS IS A CONSTANT THING, WE PULLED THE FUSE THAT CONTROLS THE BRIGHTS AND THE DIMS WORKED JUST FINE, BUT IT'S HARD TO DRIVE AT NIGHT WITHOUT BRIGHTS.
NHTSA complaint #11398596 — an unverified report by a vehicle owner.
WHEN DRIVING 30 MPH UP TO 70 MPH ALL OF A SUDDEN THE REDUCED RNGINE LIGHT VOMES ON AND THE CAR STARTS DECELERATING TO 5 MPH AND SOMETIMES CUTS OFF CAUSING POWER STEERING TO NOT WORK. THIS STARTED AFTER THE WORKED ON YHE IGNITION RECALL. I ASKED ABOUT IT AND WAS CHARGED $75 FIR THEM TO PUT IT ON THE COMPUTER. THEN WAS TOLD IT WOULD BE OVER $700 FOR THEM TO FIND OUT WHAT'S WRONG. I DON'T HAVE THAT TYPE OF MONEY SO L LET IT SIT UP FOR AWHILE ONLY TO BE YOLD IT COULD POSSIBLY BE THE GAS PEDAL AND WOULDN'T COST THAT MUCH TO REPLACE... I'VE ALMOST HAD TWO ACCIDENTS BEFORE L COULD PULL OVER. IF IT CUTS OFF COMPLETELY IT CRANKS RIGHT BACK UP - SOMETIMES OT WILL TAKE ON OFF BUT OTHER TIMES L HAVE TO SIT AND WAIT BECAUSE IT WON'T ACCELERATE NO FASTER THAN 2 TO 5 MPH, LIKE SOMETHING HAS TO CATCH UP. I HAVEN'T GOTTEN IT FIXED YET BECAUSE L CAN'T AFFORD IT.

NHTSA complaint #11326033 — an unverified report by a vehicle owner.
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.

NHTSA complaint #10893887 — an unverified report by a vehicle owner.
MY TRANSMISSION/ TRANSAXLE HAS BEEN REBUILT 3 TIMES. WHAT I HAVE RESEARCHED AT THIS TIME IS THAT THE BASE MODEL 4T65E TRANSAXLE DOESN'T REALLY DIFFER IN THE HARD PARTS FOR THE 4T65E-HD THATS IN MY PONTIAC GRAND PRIX GXP. BAD JERKING AND SLIPPING FROM TAKE OFF OR ACCELERATING IS MY PROBLEM. JUST THIS YEAR MY CAR COULDN'T ACCELERATE OVER 40MPH BECAUSE OF THIS PROBLEM. ANYONE I TALK TO WHO HAS THE SAME MOTOR COMBINATION OF THE LS4 MOTOR WITH THE 4T65E-HD TRANAXLE HAS BEEN DEALING WITH THE SAME SIMILAR ISSUES. WETHER IT BE THE IMPALA SS 2006-2009, MONTE CARLO SS 2006-2007, BUICK LACROSSE SUPER 2008-2009, OR THE PONTIAC GRAND PRIX GXP 2005-2008. THE FRONT WHEEL DRIVE COMBINATION WITH THE POWER IN THE 303 HP MOTOR IS TOO MUCH FOR THE 4T65E-HP TRANSMISSION. I'VE FOUND A WEBSITE THAT CLAIMS THEY HAVE SOLVED THE FLAWS WITH THIS PROBLEM. THE WEBSITE EXPLAINS IN DETAIL WHAT PARTS THEY USE AND HOW IT CAN SUPPORT THE POWER OF THE LS4 MOTOR. PERSONALLY I FEEL LIKE I SHOULD NOT PAY FOR SOMETHING THAT SHOULD'VE BEEN A RECALL CLOSE TO A DECADE AGO.

NHTSA complaint #10822685 — an unverified report by a vehicle owner.
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.
