VISIBILITY/WIPER, EXTERIOR LIGHTING, ELECTRICAL SYSTEM
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), my low-beam headlights didn't function at ignition one day. Obviously, lacking headlights is a core safety issue. I learned that the low-beams also use ground point G102. Once again, with the electrical ground restored via a connection elsewhere, the low-beams started working again. Two different service stations were unable to figure out the windshield wiper issue. I only solved it by reading what others wrote on a Pontiac G8 enthusiast message board. On those message board threads, you can see that many people have had these same exact issues with the Pontiac G8--all related to the G102 ground point. Obviously, having the windshield wipers and/or headlights fail suddenly and without warning (neither failure gave any warning in advance) in a situation where the wipers or lights are needed could have catastrophic consequences. Since I'm unaware of any other ground point failing on the Pontiac G8, I am wondering if G102, in particular, needs a recall and a repair, to address this. (I am the original owner. The car has been stored outside, in the Northeast.)

STRUCTURE:BODY
Was leaving for a road trip and the rear passenger door would not latch when closed. We were an hour from home, so I had to use a bungee cord to hold the door closed for the drive back. My son had to sit in the middle seat. That door is rarely used. I have ordered the part and it should be here soon. The drivers door has become difficult to open and close but I am unable to locate the part as it is backordered from GM. I understand the the vehicle is 12 years old but I maintain it very well; it is in great shape and runs well. It's scary to think that these door latches can fail so easily. Other body parts for this vehicle are becoming increasingly difficult to locate.

AIR BAGS, ELECTRICAL SYSTEM
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 replace a faulty air bag system, when this is a common issue with the 2009 Pontiac G8. This needs to be a recall as it is unfair to ask anyone to replace a VITAL and IMPORTANT safety feature of the vehicle. This should not be something Pontiac G8 owners should have to pay for out of pocket, and the Manufacturer needs to realize that this is not a one off issue, but a common issue with owners of the 2009 Pontiac G8. It is the responsibility of the Manufacturer (GM) to fix this issue as it is a basic safety issue. The car would not be legally sold with this issue from the manufacturer, so why is it the owners responsibility to pay for GM (Pontiacs) mistake? Either with $1000.00 or their lives?

WHILE DRIVING CAR ON HIGHWAY IT STARTED SHOWING AIR BAG FAULT WARNING ON THE CENTER CONSOLE SCREEN AND CORRESPONDING LIGHT CAME ON. CONSULTED WITH LOCAL GM DEALERSHIP AND DIAGNOSIS INDICATED NEED TO REPLACE THE "PASSENGER PRESENCE MODULE". THE COST QUOTED BY GM DEALERSHIP IS $855 (TOTAL), FOR PARTS AND LABOR. THIS FAULT DISABLES THE AIR BAG SYSTEM (PASSENGER AIR BAGS FOR SURE, I AM NOT SURE ABOUT DRIVER AIR BAG SYSTEM) THIS IS A SAFETY CRITICAL COMPONENT THAT SHOULD NOT FAIL AS IT DISABLES THE AIR BAG SYSTEM WHICH COULD BE LIFE THREATENING IN AN ACCIDENT. IT IS MY REQUEST TO THE NHTSA THAT THIS AIR BAG FAULT AND PASSENGER PRESENCE MODULE FAILURE SHOULD BE CONSIDERED FOR A RECALL, AS THIS IS A COSTLY REPAIR AND IS NOT A MECHANICAL COMPONENT WHICH WEARS AND TEARS OVER THE LIFE OF THE VEHICLE, ADDITIONALLY IT IS ABSOLUTELY REQUIRED FOR THE SAFETY OF THE VEHICLE OCCUPANTS.

AIR BAGS, ELECTRICAL SYSTEM, STEERING
WAS DRIVING ON BOTH HIGHWAY & NEIGHBORHOOD STREETS AND THE AIR BAG FAULT LIGHT & WARNING TONE CAME ON. AFTER MANY DIAGNOSIS DRIVE TESTS, I LEARNED THAT EVERY TIME MAKING A COMPLETE LEFT U-TURN THE AIRBAG FAULT INDICATOR WOULD DISAPPEAR. HOWEVER ONCE COMPLETING THE FULL LEFT U-TURN, AND DRIVING STRAIGHT CENTER WHEEL POSITION, THE AIRBAG FAULT INDICATOR LIGHT AND WARNING TONES WOULD REOCCUR. WHEN CONTACTING MY ONSTAR MONITORING SERVICE, THEY WERE ABLE TO DO AN OVER THE AIR DIAGNOSTIC FAULT CODE TEST. IT CAME BACK AS FAULT CODE B0012 FOR CLOCKSPRING, DRIVER STEERING WHEEL AIRBAG DEPLOYMENT LOOP FAILURE. WHENEVER THE AIRBAG FAULT INDICATOR IS ACTIVATED ON THIS MODEL, THE ENTIRE AIRBAG DEPLOYMENT SYSTEM IS COMPLETELY DISABLED AND NONFUNCTIONAL IN PREVENTING MAJOR INJURIES WHICH CAN LEAD TO FATALITIES. I CONTACTED THE DEALERSHIP TO INQUIRE OF THE REPLACEMENT CLOCKSPRING PART COST, AND WAS QUOTED IN THE $450.00 RANGE PLUS LABOR TECH INSTALL. IN ADDITION, WAS TOLD THE PART WAS ON BACK ORDER. IT HAS BEEN RECOGNIZED AS A KNOWN DEFECT ON THIS MODEL AND SINCE IS AIRBAG RELATED, SHOULD BE CORRECTED BY THE MANUFACTURER, WHICH IS GENERAL MOTORS. I COULD BE LIKE THOUSANDS OF OTHER OWNERS TO MISINTERPRET THE SEVERITY OF THIS DEFECT, AND BE DRIVING A VEHICLE THAT WILL FAIL TO SAVE MY LIFE IF EVER INVOLVED IN A MAJOR COLLISION. THIS SHOULD NOT GO UNNOTICED & SHOULD BE INVESTIGATED & RESOLVED JUST LIKE THE ONE THAT WAS FOR OTHER MAJOR CAR MANUFACTURERS FOR FAULTY AIRBAG DEPLOYMENT ISSUES. AS TO THIS DATE 06/11/2020 THE ISSUE KEEPS RECURRING ON EVERY DRIVE ON ANY STREET OR HIGHWAY. THANK YOU FOR SERVING YOUR CITIZENS & THE COMMITMENT OF MAKING THE AUTOMOBILE INDUSTRY ACCOUNTABLE FOR SAFETY. *TR

AIR BAG FAULT WARNING ON MY HUD, ALONG WITH THE CORRESPONDING LIGHT, COMES ON WHEN IT GETS COLD OUT. EVERY TIME IT GETS BELOW ABOUT 35 DEGREES THIS LIGHT WILL COME ON AND DISABLE ALL OF MY AIR BAGS.
