Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Purchased Pontiac 2008 G5 coupe brand new in 2008. In 2011 I was informed by a coworker that I was driving into work with my brake lights on all the way. He also mentioned that when it looked like I tried to apply the brakes I would have no brake lights on at all. It seemed that my brake lights worked in reverse. This was an intermittent electronic problem that was hard for the dealership to replicate. Eventually, they replaced the brake light switch. However, no one ever stopped to mention to me that my Pontiac G5 2008 was still having the problem. …”

“Under normal driving conditions front rotors warped at 17,000 miles and fixed under warranty after showing service manager vehicle warranty book. Rotors warped again at 24,000 miles and fixed again after discussion with service manager. Rotors were turned in both cases by dealer. Rotors are warping again , at 30,000 miles, for the third time and dealer refuses to address rotor warping causes but blames driver rather than rotor material. Driver has had no issues with brake pads which leads to rotors warping to excessive heat do to possible rotor material defects.”

“Approaching a busy intersection, my Pontiac G5's brakes failed to work. I could tell the hydraulics systems was working as I could hear metal on metal but it did nothing to slow down the vehicle. The vehicle's cdr showed the vehicle accelerating at full throttle although I know my foot was on the brake pedal as evidenced by the metal on metal sound. Plus a witness saw smoke coming from my vehicle. I was able to turn prior to going through the intersection and aimed for a fire hydrant to try to slow down. …”
