Recalls, owner-reported complaints, investigations and safety data
Our database contains no NHTSA owner-reported complaints for the 2024 Mci D4500. 5 manufacturer communications are on file.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.
ENGINE
This bulletin introduces an optional product improvement to the A/C compressor drive system for coaches equipped with a Cummins X12. The improved pulley system is available for customers who wish to reduce noise and vibration characteristics and may be installed at the customer’s discretion.
ELECTRICAL SYSTEM
This TSIB provides information to provide a software update. Some coaches using MCC HVAC Eco-Tempo ECU # 07-10-009 software T35-1581 / V1.04 may be experiencing random fault codes due to MCC software errors.
STEERING; SUSPENSION
This TSIB is to inform customers the recommended steering axle cleaning/greasing instructions to prevent damage on axle components due to displacement of grease from the bearings, lubrication reduction and accelerate wear for coaches with independent front suspension.
STEERING
MCI noticed that some customers operating in severe duty environments were experiencing the exterior U-Joints of the lower steering shaft binding due to corrosion. Because of this, MCI has developed a new re-greaseable U-Joint service kit (NF PN: 6505981) to replace the existing greased for life U-Joint on lower steering shafts. Rework instruction and preventive maintenance guide are provided below. Following this procedure and preventive maintenance will increase the life of MCI lower steering shafts.
This TSIB is to remind MCI coach operators that when servicing the HVAC belts, idler pulleys or the lower mount of the idler pulley bracket, ensure that the lower mount is adjusted so it is not contacting the bumper support beam nor the bumper itself.
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
