2009 Pontiac G8Electrical systemLightsVisibility & wipers

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.)

2009 Pontiac G8Body, doors & structure

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.
