2006 Pontiac Grand Prix GT 4dr Sedan (3.8L 6cyl S/C 4A)
I recently bought a gp gt and i love the way it looks, but i've been having problems with everything from tires to gas, wheelbearings just everything. I only have 8000 miles on my car the best gas mileage i've gotten is 400 miles to the tank that's bad, i got better with my 90 model pathfinder. i work for a gm dealership and none of the techs can find out what the deal is.
