Manufacturer Midwest Fire Equipment & Repair Company
Components ELECTRICAL SYSTEM, POWER TRAIN
Potential Number of Units Affected 19
Midwest Fire Equipment & Repair Company (Midwest Fire) is recalling certain 2022-2023 All-Poly Series Tanker-Pumper fire trucks, equipped with a split-shaft transmission and a Class 1 Es-Key multiplex system. A software error may cause a shift from road gear to pump gear, resulting in a loss of drive power.
Midwest Fire will provide a USB and instructions to reprogram the multiplex system software, free of charge. Owner notification letters are expected to be mailed on October 15, 2023. Owners may contact Midwest’s customer service at 1-800-344-2059.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
On April 4, 2023, customer took possession of their All-Poly Series Tanker-Pumper at which time they proceeded to drive the vehicle home. During their trip, they lost drive to the rear axle on several different occasions at which point they would pull over and shift from pump gear to road gear in order to reengage the rear axle. Once the department reached their destination, we worked with the local service center to troubleshoot the issue. After several months of trial and error, it was concluded there was intermittent power supplied to the pump shift multiplex system which allowed the air pressure for the pump shift to slowly decrease during travel. Programming was adjusted to supply constant power to the system which in turn supplied constant air to the pump shift, not allowing the truck to come out of road gear. At that time, we identified a total of 19 trucks that were programmed incorrectly & came to the conclusion a recall would be necessary.
