Review of parts returned through the Warranty Parts Center has shown a number of antenna base replacements due to the antenna mast breaking at the mounting stud.
Antenna masts that are loose or not installed properly may be damaged when the vehicle goes through an automatic car wash. Antenna masts damaged due to improper installation or because they are loose are not covered under the terms of the vehicle warranty.
