Recall 14V085 affects 96 2011-2012 Mci D4000 motorcoaches for frozen intake-manifold condensation that interferes with sensor operation. Free ECM calibration at authorized Cummins facilities.
Mci is recalling 96 2011-2012 D4000 motorcoaches with certain Cummins Westport ISL G engines because condensation in the intake manifold can freeze in cold weather and interfere with the intake manifold pressure sensor. Sensor trouble can bring elevated exhaust temperatures or flames from the exhaust pipe, raising the risk of fire or burn injury, and the dealer repair will be free once available.

What's wrong?
The intake manifold on 2011-2012 Mci D4000 motorcoaches routes air into the engine so fuel and air can be managed correctly. The intake manifold pressure sensor reads pressure inside that manifold and sends that information to the engine controls. The engine depends on that reading to manage operation in cold and normal conditions.
On affected D4000 motorcoaches equipped with the Cummins Westport ISL G engine, condensation can collect in the intake manifold. In cold weather, that moisture can freeze. Ice in the manifold can interfere with the pressure sensor, so the sensor no longer reads the intake pressure correctly or sends the engine controls the information they need.
There is no warning sign before failure. Because the problem happens inside the intake manifold and sensor area, the driver is not given a clear external cue before the pressure reading is affected.
Who's affected?
Covers the D4000 coach across the 2011 and 2012 model years, with the same engine component listed for both years.
| 2012 Mci D4000 | Engine |
|---|---|
| 2011 Mci D4000 | Engine |
| Units affected | 96 |
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?
Improper sensor operation can raise exhaust temperatures or send flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to someone standing nearby. Keep people clear of the exhaust area and arrange the ECM calibration as soon as service can take the vehicle. Repair will be free at any franchised Mci dealer once available.
What should I do?
- Check your VIN to confirm your 2011-2012 Mci D4000 is included in this recall.
- Contact Mci customer service at 1-847-285-2090 and reference recall number 14V085.
- Ask for the free ECM calibration path through an authorized Cummins service facility.
- Bring the recall notice if you have it, plus the vehicle information the service facility requests.
- Keep people away from the exhaust outlet until the ECM calibration is complete.
What happens at the repair
At an authorized Cummins service facility, the repair named in the filing is a new engine control module calibration for the Cummins Westport ISL G engine. The calibration is meant to address cold weather condensation that freezes in the intake manifold and interferes with the intake manifold pressure sensor. The dealer repair will be free once available, with the calibration uploaded at no charge under the recall. Mci also lists Mci and Cummins customer contacts for owners who need help identifying the authorized service path.

Frequently asked questions
What is recall 14V085?
Recall 14V085 covers 96 2011-2012 Mci D4000 motorcoaches with certain Cummins Westport ISL G engines. In cold weather, frozen condensation in the intake manifold can interfere with the intake manifold pressure sensor. Authorized Cummins service facilities will upload a new ECM calibration for free.
What should I do if my 2011-2012 Mci D4000 is on this recall?
Check your VIN to confirm your specific motorcoach is included in recall 14V085. If it is, contact Mci at 1-847-285-2090 or an authorized Cummins service facility to schedule the ECM calibration update. Reference recall number 14V085 when you call.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost. For recall 14V085, authorized Cummins service facilities will upload the new ECM calibration free of charge.
What is the safety risk?
The safety risk is excessive exhaust heat or flames from the exhaust pipe. That raises the risk of a vehicle fire or burn injury to a person near the exhaust pipe. The repair path is the free ECM calibration update through an authorized Cummins service facility.
What if I bought this Mci D4000 used?
The free recall repair still applies. Recall coverage follows the vehicle, not the first owner. Check your VIN to confirm whether your specific 2011-2012 Mci D4000 is included, then reference recall number 14V085 when you contact Mci or the service facility.
