Recall 15V001 affects 147 2013-2015 Mci J4500 motor coaches for brake-hose routing that risks air-pressure loss. Repair will be free once Mci opens it.
Mci is recalling 147 2013-2015 J4500 motor coaches because the steering axle brake hose can rub the front tire or upper control arm. That rubbing can wear through the hose, reduce front brake air pressure, and increase crash risk; the final dealer repair will be free once Mci opens it.

What's wrong?
The steering axle brake hose on the 2013-2015 Mci J4500 is the flexible line that carries braking pressure to the front brake chamber. That chamber applies the brake at the steering axle, so the hose has to stay clear of moving suspension parts and the front tire through turns, bumps, and normal axle movement.
On included J4500 coaches with ZF axles and independent front suspension, the hose routing and clamp position leave the hose too close to the front tire or upper control arm. As the axle and suspension move, the hose rubs against those parts. Repeated rubbing wears the hose surface and opens a path for air leakage during braking.
A driver can notice increased air consumption while braking, or hear air leaking during brake application. In certain conditions, the electronic stability control system, or ESC, also actuates during braking.
Who's affected?
All three model years point to the same brake system component.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
Rubbing can wear a hole in the brake hose, causing front brake chamber air pressure loss. That reduces brake performance and increases crash risk. Treat increased air use, air leakage during braking, or unexpected ESC activation as signs to stop and call the dealer for guidance. Repair will be free at any franchised Mci dealer once Mci opens it.
What should I do?
- Check your VIN to confirm your 2013-2015 Mci J4500 is included in this recall.
- Call Mci customer service at 1-800-241-2947 to ask for the current repair instructions for recall number 15V001.
- Ask a franchised Mci service location about interim brake-hose guidance before the coach is operated.
- Inspect the front steering-axle brake hose routing before trips, and keep the coach out of service if the hose shows rubbing, air loss, or brake-performance changes.
- Bring any owner notice to the service appointment and reference recall number 15V001 when you call.
What happens at the repair
Mci has notified owners, but the final repair is listed as under development. The issue centers on the steering axle brake hose routing and clamping, which can let the hose contact the front tire or upper control arm. Once Mci opens the final repair, an Mci technician will perform the approved repair to correct the brake hose routing or clamping. The final dealer repair will be free once available, with parts and labor covered under the recall.

Frequently asked questions
What is recall 15V001?
Recall 15V001 covers 147 2013-2015 Mci J4500 motor coaches equipped with ZF axles and independent front suspension. The front brake hose routing can let the hose rub the tire or upper control arm, causing air-pressure loss and reduced brake performance.
What should I do if my 2013-2015 Mci J4500 is on this recall?
Check your VIN to confirm your specific coach is included in recall 15V001. If it is, contact a franchised Mci dealer or Mci customer service at 1-800-241-2947 for repair instructions. Reference recall number 15V001 when you call.
Is the recall repair free?
Yes. Federal recall law requires manufacturers to repair safety defects at no cost to the owner. Mci's source filing said the remedy was still under development, so ask the dealer or Mci customer service to confirm the current repair path and covered work.
What is the safety risk?
The risk is reduced front brake performance. If the brake hose rubs long enough to wear through, the front brake chamber can lose air pressure, which increases crash risk. Ask the dealer whether the coach should be inspected before regular service use.
