I currently have my wife's Malibu that has been nothing but problems. It has blown a motor at 93k miles due to timing chain failure and was 2 months past the 5 year power train warranty. Put in a Jasper's motor and 8k miles later the same thing happened and it was replaced by Jasper. The current issue we are having is the code P1174. The light goes away once you fill up the tank but once you get to 3/4 of the tank the light comes back on and has done this for 3 fill ups. We have put a bottle of redline fuel injector cleaner with no luck. Car runs and drives fine with no issues but we are thinking might have something to do with the fuel tank since it keeps going on and off.
