2003 Mci D4000 recalls 7
Recall repairs are free. Your dealer fixes them whether or not you bought the car there - check your VIN at nhtsa.gov/recalls to see if yours is done. What to do
- The problem
- Motor Coach Industries (MCI) is recalling certain model year 2000-2012 D, E, G and J series coaches manufactured January 2000 through June 2011 and equipped with Sure Power battery equalizers containing a particular epoxy sealing, aka 'potting', compound. The specific potting compound used in the subject products for insulation was found to be capable of conducting electricity after being exposed to heat.
- The risk
- Once electrically conductive, the material is capable of melting and burning, increasing the risk of a fire.
- The fix
- MCI will notify owners, and Sure Power will replace the equalizers, free of charge. Owners may contact MCI at 1-847-285-2000. This campaign is MCI service bulletin 401.
- The problem
- Mci is recalling certain model year 2000-2009 d4000, model year 2001-2010 d4500 and model year 2005-2007 d4505 coaches equipped with ricon wheelchair lift (wcl) and a cassette-type wcl compartment door. The wheelchair lift may become disengaged from a locked position and slide unrestrained on its rollers in the storage structure, potentially breaking through the cassette door and extending beyond the outside of the door when the coach is in motion, particularly when the coach is making a left turn.
- The risk
- If the coach is in motion, potential injury to persons and/or damage to other vehicles or property could occur.
- The fix
- Mci will provide parts and labor to install free of charge to customers, a ricon designed retrofit kit that includes a spring loaded lock mechanism. The safety recall began on march 31, 2010. Owners may contact mci customer service line at 1-800-241-2947.
- The problem
- Mci is recalling certain model year 2002-2009 d series coaches, equipped with luminator horizon led side destination signs. The connector board can corrode due to an accumulation of moisture under the connector.
- The risk
- A short could occur, possibly causing smoke and fire.
- The fix
- Mci will notify owners and luminator will repair the buses free of charge. Please see luminator's defect report 09e-054. The safety recall began on november 9, 2009. Owners may contact luminator at 1-972-516-3033 or mci customer service at 1-800-241-2947.
- The problem

- The risk
- This could result in the grounding of an unprotected circuit and could lead to a thermal event if not corrected.
- The fix
- Customers are being advised to remove the boost connector and discard it. Customers will be offered a new design boost connector as an alternative at no cost. The recall began on january 2, 2007. Owners may contact mci at 1-800-241-2947.
- The problem
- On certain motor coaches equipped with a slide switch to control the defroster blower speed, there is a speed controller for each of the two defroster fan motors. The speed controller may fail causing the fan motor to operate continuously in the "high" speed mode, and the carrier slide switch may fail to reduce or otherwise control the fan motor speed.
- The risk
- The speed controller may overheat and result in a thermal even, such as smoking or possible fire.
- The fix
- Dealers will replace the defroster speed controller free of charge. The recall began on july 20, 2006. Owners may contact motor coach at 1-800-241-2947.
- The problem
- On certain motor coaches equipped with detroit diesel series 60 engines, the turbocharger compressors can fail.
- The risk
