Loved the STS and never had a problem in the 3000 miles I put on it.


Also, Northstars V8s don't have the piston slap issue. That would be the Vortec V8. I've also owned one of those motors and it was trouble free as well. Northstars have the head bolts that strip out, causing head problems. Both suffer from GMs dex-cool lifetime coolant which eats away at seals and causes all kinds of troubles. If people actually changed the fluid at regular intervals there wouldn't be many problems.

You'll find the people that knock these cars the hardest have never owned or driven one. They do have their issues, just as Mercedes and every other brand, but are overall good vehicles.
