What owners wrote

A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

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.
