2014 MCI J4500

SERVICE BRAKES, AIR

Motor Coach Industries (MCI) is recalling certain model year 2014-2019 J4500 and 2018-2019 J3500 motor coaches. The brake hoses may crack or otherwise fail resulting in an air leak. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."

Risk: A leaking brake hose could cause a delay in the actuation time of the front brake, which would increase vehicle's stopping distance and increase the risk of a crash.

STEERING:HYDRAULIC POWER ASSIST SYSTEM

Motor Coach Industries (MCI) is recalling certain 2001-2015 J4500 and 1997-2013 102EL3/E4500 coaches equipped with a hydraulic rear axle (tag axle) steering system. The axle's alignment and low hydraulic pressure in the steering system may cause the steering system to lock, causing a loss of steering control at highway speeds.

Risk: Loss of steering control may increase the risk of a crash.

SUSPENSION

Motor Coach Industries (MCI) is recalling certain 2014 -2016 J4500 vehicles. The front sway bar on these vehicles may crack at the bushing/clamp locations.

Risk: If the sway bar cracks, it can detach from the vehicle, affecting vehicle handling and increasing the risk of a crash.

SERVICE BRAKES, AIR

Motor Coach Industries (MCI) is recalling certain 2014-2017 J4500 motor coaches equipped with ZF front axles. In the affected vehicles, the front brake hose routing clamps may have been over-tightened, possibly damaging the brake hose wall reinforcement. If the brake hose wall reinforcement is damaged, the brake hose may leak. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."

Risk: If the front brake hoses leak, the distance needed to stop the vehicle may be lengthened, increasing the risk of a crash.

STEERING:LINKAGES:TIE ROD ASSEMBLY

Motor Coach Industries (MCI) is recalling certain model year 2014 J4500 and model year 2015 D4000ISTV, D4005, D4500, and D4505 motor coaches manufactured August 26, 2014, to December 3, 2014. The affected motor coaches have front and steerable tag axles whose tie rod nuts may be improperly torqued.

Risk: If the tie rod nuts are not properly torqued, the tie rod may not be adequately secured, resulting in a loss of vehicle control and increasing the risk of a crash.

SERVICE BRAKES

Motor Coach Industries (MCI) is recalling certain model year 2013-2015 MCI J4500 motor coaches manufactured July 83, 2013, to December 19, 2014 and equipped with ZF axles and independent front suspension. The routing and clamping of the steering axle brake hose to the steering axle brake chamber may allow the brake hose to rub the front tire or contact and rub the upper control arm.

Risk: The rubbing may wear a hole into the brake hose resulting in a loss of air pressure in the front brake chamber, reducing brake performance and increasing the risk of a crash.

POWER TRAIN:AXLE HUBS

Motor Coach Industries (MCI) is recalling certain model year 2014 D4500 vehicles manufactured December 19, 2013, to April 14, 2014, 2013-2014 D4505 vehicles manufactured February 1, 2013, to April 22, 2014, and 2013-2015 J4500 vehicles manufactured November 26, 2013, to May 22, 2015. The affected motorcoaches are equipped with hub carriers that may have areas of porosity which could result in the hub carrier leaking oil or cracking.

Risk: Cracks in the hub may result in hub failure, which could cause a loss of vehicle control, increasing the risk of a crash.

SEAT BELTS:FRONT:ANCHORAGE

Motor Coach Industries (MCI) is recalling certain model year 2009-2014 E4500 and J4500 motorcoaches manufactured October 2008 through October 2013, and equipped with passenger seats with 3-point seat belts. The seat track for the second row passenger seats may be missing a weld at the end of the seat track where it enters the frame structure.

Risk: In the event of a crash, the seat may detach from its floor mounting, increasing the risk of injury to the occupant.
