I HAVE SAME PROBLEM AS OTHERS. HAVE BEEN ABLE TO START CAR SOMETIMES BY PUTTING IT IN NEUTRAL. SEVERAL YEARS AGO I LEFT THE CAR WITH OUR SON TO SEE IF HE COULD FIGURE OUT THE PROBLEM BECAUSE MY WIFE QUIT DRIVING THE CAR AFTER BEING STRANDED A FEW TIMES. WHEN USING BLINKERS THE HIGH BEAM WOULD COME ON. IT HAS A ROARING SOUND LIKE A WHEEL BEARING GOING OUT.THE KEY FOB DOESN'T WORK. I'VE BEEN TOLD THE BCM BODY CONTROL MODULE COULD BE CAUSING PROBLEMS. HAD ESTIMATE OF $500 TO REPLACE AND PROGRAM NEW BCM.. WE HAVE TOWED CAR HOME AFTER GOING TO STORE. I USED TO DRIVE OTR SO WE GOT A SECOND VEHICLE TO DRIVE. AFTER READING OTHER POSTS ON THIS CAR 4/4/2021 I DON'T THINK I WANT TO PUT MORE MONEY INTO IT. ESPECIALLY WHEN I'VE READ GM TECHS CAN'T FIX THE PROBLEMS.. ONCE THE VACUUM LINE TO BRAKE BOOSTER CAME OFF WHEN MY WIFE WAS GOING DOWN HILL. I PUT THE LINE BACK ON, IT HASN'T DONE THAT AGAIN. WE HAVE NOT DRIVEN THE CAR OUT OF TOWN FOR FEAR OF IT BREAKING DOWN. AND SHOPS NOT BEING ABLE TO TELL US WHAT IS WRONG WITH IT.. I TIED A CABLE ON TRUNK RELEASE SO I CAN OPEN TRUNK. . WE DID LOVE THE CAR WHEN IT WAS RUNNING. HAS 193,000K AT THIS TIME. HAS STALLED/QUIT ON CITY STREETS. AND WE QUIT DRIVING IT ON HIGHWAY.

I HAVE A SECONDARY AIR ISSUE THAT WE CAN'T SEEM TO GET FIXED, EVEN WITH ALL THE PARTS WE HAVE REPLACED. ALSO AT NIGHT EVERY TIME I USE MY BLINKER THE HIGH BEAMS COME ON AND WON'T TURN OFF. THE ISSUE IS WHEN IM DRIVING AT NIGHT IT SEEMS TO HAPPEN WHEN MY BLINKER CLICKS BACK INTO PLACE.

MY LOW BEAM HEAD LIGHTS ARE BEGINNING TO FAIL. MY DRIVER SIDE HEADLIGHT NO LONGER TURNS ON AND I BELIEVE IT BE THE FAILURE OF THE HOOD LAMP DRIVER MODULE. AFTER REPLACING ALL BULBS AND CHECKING ALL FUSES. I HAVE CONCLUDED IT IS THIS RELAY THAT IS CAUSING MY DAYTIME RUNNING LIGHTS TO FAIL. THERE IS DOCUMENTATION THAT THIS IS A KNOWN FAILURE BUT MY CAR IS NOT SHOWING UP ON THE RECALL LIST.

ELECTRICAL SYSTEM

WHEN I START MY CAR, IT WILL STALL OUT, NOT TURN OVER OR IT WILL IDLE FOR A FEW SECONDS, THEN IMMEDIATELY SHUT OFF. I MEAN SHUT THE WHOLE CAR DOWN SO NOTHING ELECTRICAL CAN WORK AT WHICH POINT MY KEY WILL BE STUCK IN THE IGNITION AND I CANNOT GET IT OUT. I AM ABLE TO RESTART THE CAR NORMALLY, HOWEVER THE STEERING WHEEL VIBRATES ALONG WITH THE BODY OF MY CAR WHILE IN MOTION AND WHILE PARKED. WHILE MAKING A LEFT TURN THROUGH A FOUR WAY INTERSECTION, I LOST CONTROL OF MY POWER STEERING AND THE WHEEL WAS STUCK AT FIRST AND THEN SWUNG ALL THE WAY BACK WHICH SPUN MY CAR AROUND. THIS CAR HAS HAD 1 OWNER BEFORE ME AND I HAVE KEPT UP WITH ALL OF MY OIL CHANGES AND TUNE UPS. IN SEPTEMBER OF 2018, I HAD A SIMILAR ISSUE WITH THE VIBRATING AND WAS TOLD THAT A CYLINDER WAS MISFIRING AND THAT I NEEDED A TUNE UP. I SPENT $587 ON THESE REPAIRS. MY VEHICLE WAS AT 98,890 MILES. IT IS MAY 2019 ABOUT 9 MONTHS LATER MY VEHICLE IS AT 108,630 MILES AND I AM HAVING THE SAME AND ADDITIONAL ISSUES NOT EVEN 10,000 MILES MORE. I HAVE DOCUMENTATION FROM THE MECHANIC FROM MY CYLINDER REPAIRS THAT I HAVE REQUESTED TO BE FAXED OVER TO ME.

THE TURN SIGNAL STALK THAT IS ON THE LEFT OF THE STEERING WHEEL IS DEFECTIVE. WHEN THE VEHICLE IS IN MOTION ON A STREET OR HIGHWAY THE BRIGHTS WILL ILLUMINATE RANDOMLY BLINDING OTHER DRIVERS. ADDITIONALLY, WHEN MAKING A TURN AND USING THE TURN SIGNAL THE BRIGHTS WILL ALSO TURN ON WHEN THE BLINKER TURNS OFF BLINDING INCOMING DRIVERS. THIS HAPPENS EVERY DAY AND ON EVERY TRIP. THERE HAS BEEN LOTS OF RESEARCH COMPLETED AND THERE ARE SEVERAL OTHER OWNERS OF GRAND PRIXS THAT EXPERIENCE THIS SAME PROBLEM. THE FOLLOWING IS A LINK TO YOUTUBE WHERE A DRIVER EXPLAINS HIS ISSUE AND HOW TO REPLACE THE TURN SIGNAL STALK. HTTPS://YOUTU.BE/AFANEQ-P6Y8 ATTACHED IS THE EXACT PIECE THAT NEEDS TO BE REPLACED. I'D BE WILLING TO SUBMIT A VIDEO OF THE DANGER THIS CAUSES IF REQUESTED. THANK YOU.

THE PROBLEM STARTED WITH "STARTING DISABLED DUE TO THEFT SYSTEM". UPON FURTHER INVESTIGATION I GOT BODY CODES B3055 AND B2960. UPON FURTHER INVESTIGATION I FOUND ONLINE THIS TO BE A REAL PROBLEM FOR A LOT OF PEOPLE DUE TO THE PK3 SENSOR IN THE IGNITION. THE PROBLEM HAPPENED WHEN THE BATTERY HAD DIED. I JUMPED STARTED THE CAR AS PER THE MANUAL INSTRUCTS, DROVE INTO TOWN "1 MILE FROM HOME" LEFT IT RUNNING THE 20 MIN I WAS THERE COME HOME AND PARKED IT. NEXT MORNING IT WOULDN'T START AND THE INFO SCREEN SAID STARTING DISABLED DUE TO THE FT MODE. EVERYTHING OINT TO A FAULTY IGNITION AND PK3 SENSOR IN IGNITION SWITCH NOT ALLOWING IT TO READ THE ECM.

WHILE DRIVING, ESPECIALLY WHEN THE TEMP IS UNDER 40 DEGREES. I RANDOMLY GET ERROR WITH TRACTION CONTROL OFF AND REDUCED ENGINE POWER. I HAVE TROUBLE ACCELERATING AND KEEPING SPEED. WHICH HAS BEEN VERY DANGEROUS TO GET TO A SAFE SPOT ON THE EXPRESSWAY TO PULL OFF, WHEN MY SPEED SUDDENLY CHANGES. THIS HAS BEEN HAPPENING FOR THE LAST 3 YEARS DURING THE COLD MONTHS AND I HAVE GOT ITEMS CLEANED AND SENSORS CHANGED TO NO END.

BEGINNING APPROXIMATELY THE END OF MARCH, WHILE DRIVING AT NIGHT, BOTH OF MY LOW BEAM HEADLIGHTS HAVE GONE OUT AT THE SAME TIME. THEY CAME RIGHT BACK ON AT THAT TIME SO I THOUGHT I HIT A SWITCH. SOMETIME IN MAY IT HAPPENED AGAIN, BUT THE LIGHTS WOULD NOT GO BACK ON SO I USED MY HI BEAMS. THE LOW BEAMS WORKED FINE IN THE MORNING. THIS HAS HAPPENED ABOUT 3 MORE TIMES SINCE THEN AND IS BECOMING MORE FREQUENT. LAST NIGHT ON JULY 23, IT HAPPENED AGAIN ON A DARK, CURVY ROAD AND I ALMOST RAN OFF THE ROAD. THIS MORNING, THEY WORK FINE AGAIN. I CALLED THE DEALER AND THEY SAID THERE WAS NO RECALL ON THIS. I AM SURPRISED AS THIS IS A SERIOUS SAFETY ISSUE. I NEED TO GET IT REPAIRED, BUT SINCE IT IS AN INTERMITTENT PROBLEM, I SUSPECT THE DEALER WILL NOT BE ABLE TO FIND THE ROOT CAUSE OR FIX THE PROBLEM.

THE TRANSMISSION SHIFTER IS NOT TRANSMITTING AN ELECTRICAL SIGNAL TO ALLOW THE IGNITION KEY TO TURN TO THE OFF POSITION AND WILL ONLY TURN AS FAR AS THE ACC (ACCESSORY) POSITION SO THAT THE BATTERY CONTINUES TO DRAIN AND DIE LEAVING ME STRANDED IN THE NIGHT AND ON THE ROAD AND IN DANGER OFTEN. A LOCKSMITH SAID CONTINUING TO TURN AND PULL ON THE KEY TRYING TO REMOVE IT MYSELF COULD RESULT IN SERIOUS NECK AND HEAD INJURY IF THE AIRBAG WHERE TO DEPLOY WHILE I AM TRYING TO GET THE KEY UNSTUCK. I TOOK TO CHEVROLET DEALER AND HE SAID HE WOULD NEED A RECALL CODE/NUMBER TO ACCEPT MY VEHICLE FOR REPAIR WITH THIS ISSUE.
