“Door lock actuators have failed on 2 of our 4 doors. Gm refuses to cover under warranty. I'm waiting for others to fail now as this is all over the internet with similar failures for the 2009 model year. Dealer wants over $350 per door to fix. It's so bad there's a you tube video on how to fix it yourself. I believe this is a safety issue and should be a recall.”
NHTSA complaint #10563350, filed 2014-02, 60,000 miles“We have had this vehicle for three years. Roughly every 3 months it will have erratic electrical shorts and most commonly the car will not start because the battery is dead. Sometime the shorts happen while we are driving. When this happens the radio/navigation system turns off and on, the dashboard display flashes off and on, the power door locks go up and down. On a few occasions the air conditioning has switched over to heat only while the blower continued as before. …”
