The defect
Motor Coach Industries (MCI) is recalling certain 2019-2022 D4000 ISTV, D4500, 2021 D4000, D4520, 2020-2021 D4505, D4005, 2020-2022 D45CRTLE, and 2019-2021 J4500 vehicles equipped with certain Cummins X12 diesel engines. The fuel tubes between the fuel rail and the injectors for cylinders four, five, and six may fatigue and crack, which can result in a high pressure fuel leak.
The risk
A high pressure fuel leak in the presence of an ignition source can increase the risk of a fire.
The remedy
On engines with 75 miles or less, Cummins dealers will install vibration isolators to the fuel tubes. Engines with more than 75 miles will receive new fuel tubes with vibration isolators. Repairs will be performed free of charge. Owner notification letters were mailed March 11, 2022. Owners may contact MCI customer service at 1-800-241-2947. MCI's number for this recall is R21-028.
