“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.

“WHILE DRIVING THE VEHICLE THE FRONT SUSPENSION SHAKES AND CLUNKS WHILE DRIVING AT ANY SPEED. BOTH BALL JOINS HAVE TEARS IN THE RUBBER BOOTS WHICH I'M SURE CAUSES WATER AND ROAD DEBRE TO ENTER BALL JOINT AND CORRODE. THIS IS A HUGE SAFETY CONCERN FOR ME AND WHEN A BALL JOINT LETS GO IT CAN BE FATAL SENDING THE CAR IN ANY UNCHOSEN DIRECTION. PLEASE NOTE THIS IS HAPPENING TO EVERY SINGLE PONTIAC G8 OWNER I'VE COME ACROSS. THIS IS LIFE THREATENING, BALL JOINT LETS GO ON THE HIGHWAY AND THE CAR WILL GO INTO A ROLL. THANK YOU FOR YOUR TIME AND CONSIDERATION”

“LEFT FRONT WHEEL BEARING ASS'Y HAS BEEN REPLACED TWICE BECAUSE OF MOAN/ROARING NOISE THAT INCREASES AND DECREASES AS SPEED INCREASES AND DECREASES. NOISE BECOMES NOTICEABLY LOUDER AS YOU MAKE A RIGHT HAND TURN - WHICH CAUSES THE LEFT FRONT WHEEL TO HAVE AN INCREASE IN WEIGHT BEARING. ORIGINAL REPLACED @ 78,042 MILES. FIRST REPLACEMENT BECOME SO NOISY THAT IT WAS REPLACED @ 79,264 MILES. NOISE WAS LESSENED, BUT WAS STILL NOTICEABLE. NOW, THE SECOND REPLACEMENT IS SO NOISY DRIVING IT STRAIGHT DOWN THE HIGHWAY THAT I AM AFRAID TO DRIVE IT @ 90,000 MILES. *TR”
