Remedy
Cummins service centers will inspect the rail threads and fuel lines, and replace the rail as necessary, free of charge. Owner notification letters were mailed on March 7, 2022. Owners may contact Marion's customer service at 1-715-754-5261. Marion's number for this recall is 20E-032.
Chronology of events
- Feb 10, 2021
February 10, 2021 – A field service technician reported to Cummins that eight buses belonging to a single customer had been repaired since December 2020 for leaks at sealing washers in the fuel rail. February 11- March 1, 2021 – Cummins investigated the cause of the leaks with the supplier of the rail and began an investigation of field warranty claims. Cummins conducted an initial Product Safety Hazard Analysis. March 3 – April 12, 2021 – Cummins escalated the issue through its Product Safety Defect Board process, gathered additional data and revised the Product Safety Hazard Analysis. Cummins issued a Technical Service Bulletin (TSB210055) on March 4, 2021 to allow the field to replace rails that have washer leaks with a different rail and their associated fuel lines. (TSB210055 was submitted to NHTSA on April 7, 2021 in accordance with 49 CFR Part 579.5.)
- Apr 13, 2021
April 13, 2021 – Based upon the results of the investigation, Cummins’ Product Defect Safety Board decided to conduct a safety campaign on engines installed in buses, school buses, emergency vehicle and recreational vehicle applications.
