2017 FREIGHTLINER BUSINESS CLASS M2

ENGINE AND ENGINE COOLING:ENGINE:ENGINE CONTROL MODULE (ECU/ECM):SOFTWARE

Daimler Trucks North America, LLC (DTNA) is recalling certain 2015-2020 Freightliner Business Class M2 emergency vehicles equipped with certain Cummins diesel engines. The engine protection and inducement software may cause the engine to shut down unexpectedly.

Risk: An unexpected engine shutdown can delay emergency responders and increase the risk of injury.

POWER TRAIN:AUTOMATIC TRANSMISSION:COOLING UNIT AND LINES

Daimler Trucks North America, LLC (DTNA) is recalling certain 2014-2019 Freightliner Business Class M2 vehicles. The retaining clip that connects the transmission oil cooler line to the in-tank oil cooler may fail, possibly resulting in a transmission fluid leak.

Risk: If a rapid loss of transmission fluid occurs while driving, it could result in a road hazard for other motorists, increasing the risk of a crash.

EXTERIOR LIGHTING

Mickey Truck Bodies, Inc. (Mickey Truck) is recalling certain 2017 Freightliner M2, M2-106, International 4300, and 2018 Peterbilt 220 vehicles equipped with certain model lift gates that contain a license plate kit with part number 298872-01. The light kit does not properly illuminate the license plate, shining rearward, instead of downward as intended.

Risk: The improper lighting may confuse other drivers on the road, increasing the risk of a crash.

EXTERIOR LIGHTING

Daimler Trucks North America LLC (DTNA) is recalling certain 2006-2020 Freightliner Columbia, 2006-2021 Freightliner Business Class M2, 2007-2020 Freightliner Coronado, 2014-2021 Freightliner 122 SD, 2007 Sterling A 9500, 2006 Freightliner Argosy, 2006-2007 Sterling AT9500, 2008-2021 Freightliner Cascadia, 2006-2008 Freightliner Classic, 2006-2011 Freightliner Century Class, 2006-2010 Freightliner FLD, and 2017 Western Star 5700 vehicles. The rear reflective tape may be partially covered by the mudflap hanger bracket, which may reduce the vehicle's visibility to other drivers on the road. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

Risk: The vehicle's rearward visibility may be reduced, increasing the risk of a crash.

ELECTRICAL SYSTEM:WIRING

Daimler Trucks North America, LLC (DTNA) is recalling certain 2017-2021 Freightliner Business Class M2 trucks. The engine harness may contact and chafe at various locations around the air compressor and the frame rail. If the wires are damaged, they may short circuit, possibly causing an engine stall.

Risk: A engine stall may increase the risk of a crash.

STEERING

Daimler Trucks North America LLC (DTNA) is recalling certain 2017-2019 Freightliner 114SD, 122SD, 108SD, Cascadia and Business class M2 trucks, Freightliner Custom Chassis XBS, XCL, XCM, MT45, MT55, S2G, S2RV, XCR and XCS custom chassis and Western Star 4700, 4900 and 5700 trucks equipped with Detroit Axle axles. The affected vehicles may have loose steering and tie rod arm bolts.

Risk: Loose tie rod arm bolts may lead to separation of the tie rod arm, resulting in a loss of vehicle control, increasing the risk of a crash.

SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:DISC:CALIPER

Daimler Trucks North America LLC (DTNA) is recalling certain 2017-2019 Freightliner M2 Business Class, 108SD, 114SD and Cascadia trucks, Western Star 4700, 4900, and 5700 trucks, FCCC S2C 106 Cab, S2G Cab, XBR, XBS, XCL, XCM, XCP, XCR, and XCS chassis equipped with air disc brakes. The brake caliper mounting bolts on these vehicles may be insufficiently tightened, allowing the bolts to loosen.

Risk: If the brake caliper mounting bolts loosen, braking performance may be reduced, increasing the risk of a crash.

SERVICE BRAKES, AIR:DISC:CALIPER

Daimler Trucks North America LLC (DTNA) is recalling certain 2016-2019 Freightliner Business Class M2 trucks built with air disk brakes and spring suspension. The rear disk brake calipers may have been mounted in an incorrect orientation allowing the caliper to contact the suspension, reducing brake effectiveness.

Risk: Reduced braking effectiveness can increase the risk of a crash.

ELECTRICAL SYSTEM:SOFTWARE

Daimler Trucks North America LLC (DTNA) is recalling certain 2016-2017 Freightliner Business Class M2, 108SD, and 114SD trucks. The affected trucks have been modified to be equipped with both left hand and right hand instrument clusters. Due to incompatibilities between the displays, the instrument clusters and/or turn signals may become unresponsive.

Risk: Unresponsive instrument clusters and/or turn signals can increase the risk of a crash.

SERVICE BRAKES, AIR

Daimler Trucks North America (DTNA) is recalling certain 2015-2017 Freightliner M2 Business Class, 108SD, and 114SD vehicles. The affected vehicles might not have a required check valve installed in one of the ports of the spring brake modulation valve. Without the valve, the primary air system is not isolated from the secondary air system.

Risk: A rapid loss of air pressure in the secondary system could cause a similar rapid loss of pressure in the primary system, which may lead to a sudden application of the parking brakes. This could increase the risk of a crash.

TIRES:TREAD/BELT

Daimler Trucks North America LLC (DTNA) is recalling certain model year 2017 Freightliner Cascadia, Business Class M2, and 122SD trucks manufactured January 24, 2016, to October 10, 2016 and equipped with Goodyear G399A LHS 295/75R22.5 Load Range G tires. The tires on the affected vehicles may have cured improperly, possibly resulting in a partial tread separation.

Risk: Partial tread separation can increase the risk of a crash.

SERVICE BRAKES, AIR:DISC:CALIPER

Daimler Trucks North America LLC (DTNA) is recalling certain model year 2010-2017 Freightliner M2 Business Class, 108SD, 114SD, and Columbia trucks manufactured from January 6, 2010, through February 29, 2016, equipped with certain Bendix rear disk brakes and spring suspensions. The rear disk brake caliper may have been installed incorrectly, thus allowing the caliper to contact the suspension.

Risk: Caliper contact with the spring suspension may reduce the braking effectiveness, increasing the risk of a crash.

POWER TRAIN:AXLE HUBS

Daimler Trucks North America LLC (DTNA) is recalling certain model year 2014-2017 Freightliner M2 Business Class, 108 SD, 114 SD, Cascadia, Coronado, Western Star 4700, 4800, and 5700 XE trucks manufactured March 15, 2013, to July 29, 2016 and equipped with Conmet aluminum non-high capacity hubs. These vehicles specify a front axle weight limit that may be greater than that of the hub capacity. As a result, the hub may fail and the wheel may separate from the axle.

Risk: If a wheel separates from the axle, there would be an increased risk of a crash.

SERVICE BRAKES, HYDRAULIC

Daimler Trucks North America, LLC (DTNA) is recalling certain model year 2016-2017 Freightliner Custom Chassis (FCCC) S2 chassis and Freightliner Business Class M2 trucks and non-school buses manufactured March 3, 2015, to September 8, 2016, equipped with ICU3s instrument clusters and hydraulic brakes. In the event of a brake malfunction, these clusters may illuminate the Brake System Malfunction telltale/indicator lamp with the word "PARK" instead of the word "BRAKE". As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 101, "Control and Displays," and number 105, "Hydraulic and Electric Brake Systems."

Risk: If "PARK" illuminates instead of the word "BRAKE," the driver will be unaware of a braking issue or malfunction, increasing the risk of a crash.
