2016 Ford F-150 - Worried about warranty

2016 F150 26,000 miles. The paint is chipping off all 4 door handle inserts, Body shop says it’s plastic that omits chemicals that release the paint. They are going to remove, sand, repaint BUT They say it will happen every 2-3 years from now on. Ford needs to replace these with aluminum ones like the body. Will the warranty be extended on these.

Sorry, Wrong place to ask. You should ask that of your Ford dealer.
