Problem 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. Fix 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.

Two numbers, one recall

Every safety recall carries two identifiers. R21-028 is the number MCI assigned in its own system: it is what appears on the owner letter, on the dealer’s service screen and on the repair order. 21V971000 is the number NHTSA filed the same recall under when the manufacturer reported it, and it is the one every federal record, this site included, is keyed on.

The repair is free by federal law for vehicles up to fifteen years old. Whether one particular vehicle is included is settled by its VIN against the manufacturer’s build list, not by its model year.

Check one specific vehicle

Both lookups check a VIN against the manufacturer’s own list and say whether the repair is still outstanding on that vehicle.

Common questions

Is R21-028 the same recall as 21V971000?

Yes. R21-028 is MCI’s own number for it; 21V971000 is NHTSA’s. One recall, two references.

Which vehicles does R21-028 cover?

2019–2022 MCI D4000 and 7 other MCI models, 1,125 vehicles by the manufacturer’s count. A recall covers a build range, so the VIN decides whether one particular vehicle is in it.

Does the R21-028 repair cost anything?

No. The manufacturer must remedy a safety defect at no charge for vehicles up to 15 years old from first sale.
