Intake gasket replacement, Wheel bearings.
The engine in this car is horrible. It has piston slap until the engine is warmed up. Also has an unknown knock in engine at all temps. It get less than 25MPG. I change the oil every 2000 miles and maintenance the car often, and yet it is still going down hill. This car is a gas hog with no power, and sounds like its blowing up. GM Claims the piston slap is normal, I don't know about that.
Any gas mileage above single digits is really pretty good gas mileage!
"GM Claims the piston slap is normal, I don't know about that."
- Piston slap is not normal. Once more, GM is sticking its head in the sand over one of its many problems. See http://www.pistonslap.com/ for more information about this.
