Motor Coach Industries, Inc. (MCI) is recalling certain model year 2011-2012 D4000 motorcoaches manufactured March 2011 through July 2012 and equipped with certain Cummins Westport model ISL G. Condensation in the intake manifold may freeze during cold weather conditions and interfere with the proper operation of the intake manifold pressure sensor.
The improper operation of the sensor could induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to a person near the exhaust pipe.
MCI will notify owners, and authorized Cummins service facilities will upload a new ECM calibration, free of charge. The recallbegan on April 16, 2014. Customers may contact MCI at 1-847-285-2090 or Cummins Inc. at 1-800-343-7357. MCI's number associated with this campaign is 405.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
