Since you mentioned Fiat and Chrysler . . . . Bought a Jeep Renegade a few years ago, the only American SUV built entirely in Italy. After a while the sunroof stopped working. Figgered there might be a hack to fix it so I went online to Google it. Gave up after much searching because all I could find were posts by other guys on various forums asking for the same hack to fix the same problem. Next morning my brain practically shouted at me "You were Googling the wrong search terms!" Went back online and searched "sunroof reset Fiat 500" and BANG there was my answer right on page one.
