Defect. Motor Coach Industries (MCI) is recalling certain 102DL3, 102D3, MC12PTV, E4500, D4000, 102D3ISTV, D4500, J4500, D4000ISTV, D4005, D4505, and J3500 transit buses. Please refer to MCI's recall report for specific model year information. The front door lower curb view glazing material is incorrect. As such, these vehicles fail to conform to Federal Motor Vehicle Safety Standard (FMVSS) number 205, "Glazing Materials."

Risk. The incorrect window glazing material may reduce the driver's visibility, increasing the risk of a crash.

Remedy. MCI will replace the glass, free of charge. Owner notification letters were mailed February 4, 2026. Owners may contact MCI customer service at 1-800-241-2947. MCI's number for this recall is 22-005.

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.

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.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
