1999 Oldsmobile Cutlass GLS 3.1 V6 from North America
$7600 piston slapping gas hog
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 the engine at all temps. It get less than 25MPG. I change the oil every 2000 miles and maintain the car often, and yet it is still going down hill.
This car is a gas hog with no power, and sounds like it's blowing up. GM claims the piston slap is normal; I don't know about that.
Would you buy another car from this manufacturer? No

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.
