POWER TRAIN:AUTOMATIC TRANSMISSION:PARK/NEUTRAL START INTERLOCK SWITCH

Daimler Trucks North America, LLC (DTNA) is recalling certain model year 2017 Freightliner Custom Chassis (FCCC) S2 bus chassis manufactured November 25, 2015, through April 27, 2016. The brake transmission shift interlock feature may be inoperable making it possible to shift into a drive gear without first pressing the brake pedal.

Risk: This condition can result in the vehicle moving unintentionally or rolling away, increasing the risk of injury or 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.
