Recall 11V524 covers 1,962 Mci 2003, 2007, 2008, 2009, 2010, 2011, 2012 motor coaches for ESC braking intervention. Free control module replacement.
Mci is recalling 1,962 2003, 2007, 2008, 2009, 2010, 2011, 2012 D4000, J4500, E4500, D4505, D4500, D4005, and D4000ISTV motor coaches because the electronic stability control system can misread body roll and road angle, then apply a front outer wheel brake. If the driver reacts slowly during that intervention, the coach can leave its intended line of travel, which raises crash risk; the dealer repair will be free once available.

What's wrong?
The electronic stability control system on the affected Mci 2003, 2007, 2008, 2009, 2010, 2011, and 2012 D4000, J4500, E4500, D4505, D4500, D4005, and D4000ISTV motor coaches is designed to help keep the coach stable when sensors detect a loss of control. It reads vehicle movement, including body roll and wheel behavior, then commands braking at individual wheels when it sees a stability problem.
On these coaches, the Meritor WABCO ESC module can misread body roll and road incline while calculating the coach's slip angle, which is the angle between where the coach points and where it is moving. Under those road and driving conditions, the system can mistake normal movement for oversteer and apply the outer front wheel brake until it believes the coach is stable.
There is no warning sign before failure. The first thing a driver notices can be unexpected braking at one front wheel while the coach is moving through the road and driving conditions that trigger the false ESC response.
Who's affected?
Spans the D4000, J4500, E4500, D4505, D4500, D4005, and D4000ISTV coach lines, all tied to electronic stability control.

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?
During an ESC intervention, a delayed driver response can let the vehicle move away from its intended travel path, increasing crash risk. Drive cautiously until the recall repair is complete, especially if stability control activates. Repair will be free at any franchised Mci dealer once available.
What should I do?
- Check your VIN to confirm your 2003, 2007, 2008, 2009, 2010, 2011, or 2012 Mci D4000, J4500, E4500, D4505, D4500, D4005, or D4000ISTV coach is included in this recall.
- Contact a franchised Mci dealer or Mci customer service to ask about the free ESC control-module replacement.
- Bring the owner letter if you have it. If not, reference recall number 11V524 when you call.
- Ask the dealer to replace the ESC control module, which fixes the stability-control brake intervention that can pull the coach from its intended path.
- Drive cautiously until the repair is complete, especially in road and driving conditions where the ESC system activates.
What happens at the repair
The source remedy says Mci notified owners and began the safety recall on January 4, 2012. At the dealer, an Mci technician replaces the electronic stability control module. That module helps the coach read stability inputs and apply braking commands correctly. The replacement control module is provided free of charge under the recall. If the coach still has an open recall, ask the Mci service desk to confirm parts availability before bringing it in.

Frequently asked questions
What is recall 11V524?
Recall 11V524 covers 1,962 2003, 2007, 2008, 2009, 2010, 2011, 2012 Mci D4000, J4500, E4500, D4505, D4500, D4005, and D4000ISTV motor coaches with Meritor WABCO electronic stability control modules. Mci will replace the control module for free.
What should I do if my 2003, 2007, 2008, 2009, 2010, 2011, 2012 Mci D4000, J4500, E4500, D4505, D4500, D4005, or D4000ISTV is on this recall?
Check your VIN to confirm your specific motor coach is included in recall 11V524. If it is, contact a franchised Mci dealer or Mci customer service at 1-800-241-2947 to arrange the control module replacement. The repair is free.
Does the recall repair cost anything?
No. Federal recall law requires the manufacturer to repair the defect at no cost, and Mci's remedy is a free control module replacement. The safety recall began on January 4, 2012, so owners can contact Mci about completing the repair.
What is the safety risk in recall 11V524?
The safety risk is unintended brake application from the electronic stability control system under certain road and driving conditions. If the driver reacts slowly during that intervention, the motor coach can move away from its intended travel line, increasing crash risk.
What if I bought the Mci motor coach used?
The free recall repair still applies. Recall coverage follows the VIN, not the first owner. Check your VIN to confirm whether your coach is included in recall 11V524, then reference that campaign number when you contact the dealer or Mci customer service.
