2009 PONTIAC G8 Electrical System Problems

7/17/21 (about 94500 miles) - While driving in heavy rain on a congested highway, with my windshield wipers turned on (of course), the wipers suddenly stopped working. This could have easily killed me and my family. The wipers would not turn back on, no matter what I did. At a rest stop that afternoon, and then later during extensive testing, I found that turning the wipers on would never actually make the wipers activate--but it would cause the engine to shut off and caused the car to issue numerous, varying error codes related to numerous vehicle systems (including ABS). Through much difficulty, I was able to find that this was caused by a faulty electrical ground at what's known on the Pontiac G8 as ground point G102. The electrical ground was restored via ground connection elsewhere, and the wipers resumed functioning. Roughly 2 years later (July/August 2023, about 104,000 miles),...

A month ago my passenger air bag light came on indicating there is an issue with the Passenger Air Bag system. This occurs even when there is no one in the passenger seat. This completely disables the airbag system in my car for my passengers and I can no longer reliably transport other passengers for fear of getting into an accident and the air bag not deploying. These parts are not normal mechanical pieces that wear and tear over the course of the cars life, and with a quote from the dealership of almost $1000.00 it is unreasonable for me to pay as this is a HUGE SAFETY ISSUE, not only to passengers but to myself as I am unsure if this will effect the Drivers Air Bag System. I dont think its fair that with the car only being 12 years old that I should have to pay and...

BRAKE LIGHTS WILL ILLUMINATED - WHEN THE BRAKE PADDLE IS PUSHED UP THE BRAKE LIGHTS WILL TURN OFF FOR A SHORT TIME AND THAN ILLUMINATE AGAIN. THIS HAPPENS WHEN THE VEHICLE IS STATIONARY, IN MOTION, ON A CITY STREET AND ON THE HIGHWAY. *TR

OUR 2009 PONTIAC G8 GT WITH 54,000 MILES STARTING HAVING THE AIR BAG FAULT LIGHT SHOW UP DURING STARTUP OF THE VEHICLE. THIS FAULT STAYED ILLUMINATED AT ALL TIMES. I RESEARCHED THIS FAULT ON THE INTERNET, INCLUDING PONTIAC FORUMS, AND FOUND THAT THERE WAS A SIGNIFICANT AMOUNT OF OTHER PONTIAC G8 OWNERS THAT HAVE HAD A SIMILAR FAULT. I ALSO FOUND ON THE INTERNET THAT THERE WAS A LARGE AMOUNT OF GM PRODUCTS THAT HAS THE SAME FAULT. I FOUND THAT THE MAJORITY OF THE FINDINGS ON THE INTERNET STATED THAT THE ISSUE WAS THE PASSENGER PRESENCE MODULE AND/OR SENSOR. ON 4-22-14, WE TOOK OUR G8 TO THE DEALERSHIP FOR ANALYSIS. THE DEALERSHIP FOUND THAT THE FAILURE WAS THE PASSENGER PRESENCE MODULE (PN#92225595) AND PASSENGER PRESENCE SENSOR (PN#92220398). THE AIR BAGS IN THE VEHICLE WILL NOT FUNCTION WITH THIS CURRENT FAULT. THE COST TO REPAIR THE ISSUE QUOTED BY THE...

THE AIR BAG FAULT LIGHT CAME ON IN OUR 2009 PONTIAC G8. THE CAR HAS ONLY 41,000 MILES. WHY WOULD AIR BAG SYSTEM FAIL? IT HAS NO ACCIDENTS AND LOW MILES. TOOK TO DEALER "QUALITY CHEVROLET IN ESCONDIDO CALIFORNIA TO HAVE THE CODES READ AS MY READER WOULD NOT DISPLAY THEM. DEALER SAID THEY WOULD DIAGNOSE IT FOR $115.14. DEALER KEPT IT TWO DAYS AS THEY SAID THEY WERE TOO BUSY WITH GM IGNITION KEY RECALL AND DIDN'T HAVE TIME TO READ THE ERROR CODES. THE SECOND DAY, DEALER SAID "BAD NEWS", YOU WILL NEED TO PAY US AN ADDITIONAL $1,041.00 TO REPLACE THE PASSENGER SEAT PRESENCE MODULE. TOTAL WOULD BE $1,156.14. THEY SAID ALL OF THE AIR BAG SYSTEM WON'T WORK WHILE YOU HAVE THIS ERROR CODE. THIS IS CRAZY. A SAFETY SYSTEM LIKE THIS SHOULD NOT FAIL AND IT SHOULD NOT KILL ALL THE OTHER AIR BAGS. I...

UNABLE TO REMOVE KEY FROM IGNITION. ..UPDATED 07-05-13 *BF

AIR BAG FAULT OCCURRED AND DISPLAYED IN TWO PLACES ON MY DASH WHEN I STARTED MY CAR TO GO TO WORK. I HAD NOT DRIVEN THIS CAR IN A MONTH AND JUST A FEW WEEKS PRIOR TO THE LAST TIME IT WAS DRIVEN I HAD ANOTHER AIRBAG RECALL PERFORMED. TOOK CAR TO THE DEALERSHIP TO FIND OUT THE PASSENGER SENSOR MODULE HAD A SHORT CIRCUIT IN IT. UNKNOWN TO ME ALL THE VEHICLE AIRBAGS WERE DISABLED WITH THIS FAULT PER THE SERVICE TECH. IT SEEMS TERRIBLE UNSAFE TO DISABLE ALL AIRBAGS FOR A PASSENGER SENSING MODULE. IT SHOULD FAIL ACTIVE RATHER THAN FAIL PASSIVE FOR SAFETY. I HAVE ALSO FOUND NUMEROUS REPORTS OF THIS MODULE FAILING NEAR THE TIME OF WARRANTY EXPIRATION NOT NECESSARILY AFTER. THOUGH MINE WAS AFTER BY DATE NOT MILEAGE. *TR

I AM THE 2ND OWNER OF THIS VEHICLE I BOUGHT IT WITH 20,000 MILES AND NOW IT HAS 41,000. THE CAR HAS HAD 5 RECALLS SINCE I HAVE OWNED IT WHICH I UNDERSTAND IS NOT A BAD THING CAUSE THEY ARE FIXING THE PROBLEMS,BUT WHEN THE PROBLEM KEEPS EXISTING AND GM SAYS "ILL GIVE YOU A YEAR FREE MAINTENANCE FOR THE TROUBLE" COME ON, I HAVE 3 KIDS THAT RIDE IN THE CAR,AND PARTS THAT DON'T BELONG ON THE CAR BECAUSE THEY DON'T MAKE THEM ANYMORE, (WIRING HARNESS) THE ENGINE LIGHT KEEPS COMING ON AND NOW I HAVE NO HIGH BEAMS , GM RESPONSE TO THAT WAS "WE WILL PUT NEW BULBS IN FOR YOU TO SEE IF THAT WORKS" HELLO WHEN BOTH LIGHTS GO OUT THE SAME TIME AND THE ENGINE LIGHT COMES ON I MAY NOT BE AN EXPERT BUT I CAN SAY I THINK THERE JUST MIGHT...

VEHICLE WILL SUDDENLY THROW ABS/TRACTION CONTROL/BRAKE SYSTEM/AIRBAGS FAILURE NOTICES; VEHICLE THEN GOES INTO LIMP MODE AND THE TRANSMISSION LOCKS INTO FIRST GEAR. HAS OCCURRED 3 TIMES, DEALERSHIP UNABLE TO DIAGNOSE OR REPAIR. THEY HAVE CLEARED ALL MIL/DTC CODES AND RE-FLASHED ECM 3 TIMES. THE PROBLEM HAS OCCURRED ONCE ON THE INTERSTATE IN HEAVY TRAFFIC AT 70MPH AND TWICE ON CITY STREETS IN RUSH HOUR TRAFFIC, WITH SIGNIFICANT CHANCE FOR ACCIDENT/CRASH. WHEN THE VEHICLE EXHIBITS THIS CONDITION, LOSS OF CONTROL OCCURS, AS ENGINE DELIVERS NO POWER TO TRANSMISSION AND CAR IS LIMITED TO 25MPH MAXIMUM SPEED. *TR
