What's wrong?
The hub carrier on the 2013-2015 Mci D4505, J4500, and D4500 motorcoaches is part of the drive axle at the wheel end. It supports the wheel hub and keeps the rotating parts aligned while the coach carries load, brakes, and turns. It also helps keep axle oil where it belongs.
On affected coaches, the hub carrier casting has porosity, which means small voids or weak spots formed inside the metal. The weak area is in a high-stress part of the carrier. As the part ages under normal axle load, a crack can start at that porous area, leading to oil leakage or the hub no longer running true.
The warning signs are oil leakage, vibration, or noise when braking. ZF reported that the caliper supports the hub carrier, so there is no spontaneous wheel loss, and the driver notices the damage early enough to stop the vehicle.

What's the safety risk?
A cracked hub can fail, cause loss of vehicle control, and increase crash risk. Oil leakage, vibration, noise while braking, or run-out error are warning signs; treat them as a reason to stop and call the dealer. Repair is free at any franchised Mci dealer.
What should I do?
- Check your VIN to confirm your 2013-2015 Mci D4505, J4500, or D4500 is included in this recall.
- Contact a franchised Mci dealer to schedule the free hub-carrier inspection and replacement that addresses oil leaks, cracks, and hub failure.
- Reference recall number 15V389 and Mci recall SB 425 when you call.
- Bring the recall notice if Mci mailed one, along with service records for any axle-hub work already done.
- Drive cautiously until the repair is complete, and stop using the motorcoach if you see hub oil leakage or hear axle-hub noise.
What happens at the repair
At the dealer, a Mci technician inspects the hub carriers for oil leaks and signs of cracking. If the inspection finds an affected hub carrier, the dealer replaces that hub carrier at no charge under the recall. Parts and labor are covered. Ask the service desk to confirm that the inspection and any hub carrier replacement are both handled under recall SB 425.

Frequently asked questions
What is recall 15V389?
Recall 15V389 covers 232 2013-2015 Mci D4505, J4500, and D4500 motorcoaches with hub carriers that can leak oil or crack. Cracks in the hub can lead to hub failure and loss of vehicle control, increasing crash risk. Mci dealers will inspect and replace affected hub carriers for free.
What should I do if my 2013-2015 Mci D4505, J4500, or D4500 is on this recall?
Check your VIN to confirm your specific motorcoach is included in recall 15V389. If it is, contact a franchised Mci dealer or Mci customer service at 1-800-241-2947 and reference recall SB 425. The dealer inspection and hub carrier replacement are free.
Is the recall repair free?
Yes. Federal recall law requires manufacturers to repair safety defects at no cost, and Mci's remedy says dealers will inspect for hub carrier leaks and replace affected hub carriers free of charge. Parts and labor are covered through a franchised Mci dealer.
What is the safety risk?
The safety risk is hub failure. The recalled hub carriers can leak oil or crack, and cracks in the hub can lead to loss of vehicle control, increasing crash risk. Confirm your VIN, then arrange the free dealer inspection and replacement if your motorcoach is included.
What warning signs should I watch for?
Watch for oil leaks around the axle hub area. Mci's remedy starts with a dealer inspection process to identify hub carrier leaks, then replacement of affected hub carriers. Even if you do not see a leak, use the VIN check because inclusion depends on the specific motorcoach.
