After two visits and several hours they said the passenger side seatbelt retractor was fixed. Its early locking issue was resolved. Except it was not only NOT fixed, but now the seatbelt is totally locked in the retracted position. So, of course, the warning bell will not stop if someone sits in the passenger seat. So back again to have them redo the repair. They have now lost a customer for ever!
Okay, here's the final chapter, hopefully the seatbelt story. Apparently, the replacement parts sent by Fiat to the dealer were faulty. Scottsdale Fiat finally removed a functional seatbelt retractor from another vehicle and put it in my car. So far so good. Thank you Fiat of Scottsdale. Special thanks to Ozzie in sales, and Bill in service.
