Chronology of events

1. Aug 4, 2022

   On 8/4/2022, Cummins contacted Rosenbauer alerting them of a recall impacting 7 engines we purchased for our Rosenbauer chassis. The ESNs were provided and matched up to the VINs that same day and verified on Friday 8/5/2022. The list was sent back to Cummins and Production at Rosenbauer was alerted. The engines were not installed in trucks yet and were located on Monday 8/8/2022 at Rosenbauer Motors (Chassis) Plant in MN. Cummins White Bear Lake was notified and Cummins Corporate shipped replacement ECMs to Cummins WBL. The Cummins tech came to Rosenbauer Motors on 8/10/2022 and successfully replaced the ECMs on all but 1 engine for Rosenbauer chassis. On Monday 8/8/2022, Cummins alerted Rosenbauer of the Commercial chassis that were impacted as well per their report on shipped engines to Daimler Trucks. On Wednesday 8/10/2022, those ESNs and VINs were matched up and 4 more have been added to the population. Because these trucks are assumed to be in Production, they were alerted Thursday 8/11/2022 to locate the chassis. Rosenbauer fully expects more Commercial trucks to be added and will need to file an amendment as information is acquired. However, we have notified Cummins Sioux Falls to replace the ECMs since the trucks are located at our Lyons, SD plant. As of 9/13/22, all trucks were remedied while in Production at Rosenbauer prior to any delivery or shipment to customers.
