In the document (ZD8), although my VIN does not appear, I have unfortunately encountered the SAME EXACT problem. My Jeep first exhibited this issue back in 2022, and I managed to repair it at that time without being aware of the existing recall. As it stands, my vehicle is now at the dealership again, plagued by the SAME recurring issue.

My vehicle is experiencing a strong fuel smell and visible fuel leak, and a technician confirmed the failure of the fuel line. However, my VIN does not currently show as included in the recall, and I have been told the repair is not covered under warranty. Given that my Jeep has the same engine, same part number, and identical symptoms described in the official recall - I'm requesting one of the following: That the dealer be allowed to inspect the fuel line's date code and replace it under Recall Y10 if it falls within the affected range, or That Jeep/Stellantis cover the cost of the repair as a goodwill safety-related assistance, since the …
