The contact owns a 2009 GMC Sierra 1500. The contact started the ignition and heard a loud knocking noise on the outside of the vehicle. The failure began one week after the vehicle was purchased. In addition, the brakes would shake and vibrate when they were engaged. The engine consumed an excessive amount of oil. The air bag sensor also caused the air bag warning light indicator to illuminate. The vehicle was taken to an authorized dealer where the engine and air bag sensors were replaced. The engine failure continued to occur after the engine was replaced. The contact stated that the vehicle was taken to the dealer fifteen times. The manufacturer was notified of the failures and only offered her a free oil change for one year. The vehicle was not repaired. The failure mileage was approximately 1,000.
I stated my truck to warm it up when I got in and started to drive I had no power steering or power brakes. I revved the motor a little and I could hear the power steering pump make a noise and it started working. I took it to the dealer who said they could not find anything wrong.
