Technical service bulletins and other communications the manufacturer sent dealers about this vehicle. Ask a dealer for the full document by its number.

• 11005258This document is an aid to dealers in the repair of a floor truss support.
• 10235513FCA US has decided that certain vehicles fail to conform to Federal Motor Vehicle Safety Standard (FMVSS) No. 106 - Brake hoses. Constriction requirement states, "Except for that part of an end fitting which does not contain hose, every inside diameter of any section of a hydraulic brake hose assembly shall be not less than 64 percent of the nominal inside diameter of the brake hose." Brake hoses that have an out of specification orifice diameter have an inside diameter that is less than the 64 percent requirement.
• 10228206The awning while deployed, may not retract in a wind event, due to the wind sensor potentially having the power bypassed and shut off.
• 10206639Per DTNA recall FL888 21V369 and 21V370; The tie rod clamp may be loose due to the supplied lock nuts being over-crimped. This can cause thread galling of the bolt and nut during installation. When galling occurs, it is possible that assembly torque may be achieved but the clamp is still loose. The tie rod clamp being loose could lead to the threaded tie rod ends becoming loose and eventual steering loss if the rod end pulls out of the tie rod, or the tube is broken due to vibration of the loose joint, creating the risk of crash.
• 10199445The flanged wheel lug nuts on your vehicle may have been over-torqued during service to an incorrect torque specification in the Service & Owner's manuals. A yielded wheel stud may eventually break, which could lead to a wheel separating from the vehicle during operation. A wheel separating from the vehicle could cause a vehicle crash without prior warning and/or the wheel/tire could pose a risk to other vehicles or pedestrians.
• 10199340Per FCAs Recall 21V439, the engine calibration software may not warn of low oil volume.
• 10198106The transmission control module software in your vehicle may cause the transmission to slip or will not go into gear at all. In addition, the Malfunction Indicator Lamp (MIL) may illuminate on the cluster.
• 10197004The retaining washer and bolt that connect the brake pedal to the bearing block may come loose and detach. This could cause the brake lights to stay illuminated, even when the brake pedal is not pressed.
• 10193872It was discovered that the manufacturing plant did not cut a stress relief line in the upper deck Driver Side and in on certain models, Passenger Side under the slide room(s). The upper deck in the Impression Fifth-Wheel needs to flex, without the "stress relief cut" the sidewall filon may crack under the slide room(s).
• 10191040The add on component separates the tail light signal from an actual brake signal so the customers no longer need to mess with their brake controller when towing as the Freightliner M2 Chassis applies brake signal to the four-way flashers, which in turn will activate the brakes of a towed item, such as a trailer. In some states, it is required to activate the vehicle four-way flashers on certain Grades.
• 10190569Relocation of the Mobileye Fuse.
