2007 Chevy Silverado LTZ Window Trim Corrosion

Asked by Apr 08, 2008 at 08:09 PM about the 2007 Chevrolet Silverado 1500 LT2 Crew Cab 4WD

Question type: Maintenance & Repair

I have a 2007 Silverado LTZ with streaks from corrosion running down the rear doors.  It is coming from beneath the window sill trim.  The corrosion is from aluminum and not steel.  The dealer said that it could be cleaned with Mother's or MaGuire's cleaner wax.  My question is this, has anyone else had this problem?  Did you or your dealer find a permanant solution?  I've owned Chevy trucks all my life and never had this occur before. I would appreciate any feedback that's out there.

something is not right, dealer might not want to do warranty work (they get paid less and it a large process to get there money back) try another dealer, and see what they say, they might have to replace the trim, but yes a good wash/wax will take care of that. of the 8 06-08 Gm900 on the fleet we dont have that issue and they are white. but I would try another dealer
