The parking brake on my 07 pontiac g5 gt has already been repaired under warranty for a plastic piece of the ratchet mechanism in the handle breaking. In order for the parking brake to be reasonably effective on a hill, it must be very firmly applied. With the knowledge of the ratchet already giving out once, I'm wary of leaving my car parked without the transmission in gear to aid the parking brake to avoid a roll-away. The brake continues to be insecure when under nominal tension.
2007 Pontiac G5 brakes complaints

Tl*the contact owns a 2007 pontiac g5. While driving 40-45 MPH, the vehicle lost steering power and there was a knocking sound when turning the wheel. The contact also heard a loud clunking noise coming from the steering wheel occasionally. The brakes also failed and she crashed into a police vehicle. The dealer stated that the steering shaft needed to be replaced, as well as the rotors. After the dealer stated that they had made the repairs, the contact was informed a few days later that the parts for the repair were finally available; however, the repair was supposedly performed already. The failure mileage was 91 and current mileage was 7,188.
When pulling up the parking brake lever to sufficiently hold the car on a grade, the pawl (plastic part) failed, and the lever wasn't held mechanically in the 'on' position. Typically, the parking brake on disc-equipped rear axles of chevrolet cobalt/ pontiac g5 must be very tight to effect any significant hold on a grade. This is the experience of me, and other g5/cobalt drivers -- with increasing frequency. It was repaired for me under warranty, but I don't know if it was either replaced with a similar part, or a redesigned one.
