All recalls
Electrical system: instrument cluster/panel
- What is wrong
- Motor Coach Industries (MCI) is recalling certain 2018-2026 buses. Please see the complete list of models above. The instrument panel indicator light may not illuminate when the hazard warning lights are on and the master run switch is in the 'Off' position. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
- Risk
- Without the illuminated reminder, the driver may fail to turn off the exterior lights when no longer needed. Hazard warning lights that remain activated unintentionally can confuse other drivers, increasing the risk of a crash.
- Remedy
- MCI will update the software, free of charge. Owner notification letters are expected to be mailed November 24, 2026. Owners may contact MCI customer service at 1‑800‑241‑2947.

Fuel system, diesel: fuel injection system: fuel rail
- What is wrong
- 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.

- Risk
- A high pressure fuel leak in the presence of an ignition source can increase the risk of a fire.
- 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.
