Anyone have experience with the corrosion warranty on a Pontiac Grand Prix? Ordered mine spring 1998, delivered June 4 1998, Unfortunately have to endure Upstate NY winters but wash underbody whenever possible in winter, always wax several times a year, body looks impeccable but near gas fill cover on back fender noticed four tiny bumps in paint, rust coming through , not on outside yet but will be. The soonest I have ever had any rust thru on a car up here was eight years and that was on a 1973 vehicle. I never garage them in the winter, let the stuff stay frozen on the car.
Taking to local dealer on Wednesday and they will "look" at it.
