Freightliner Business Class M2: Brakes
Affects Freightliner Business Class M2 · 2013–2015 — about 218 vehicles.
The hazard
On certain vehicles equipped with an Auto-park brake feature, the parking brake may apply unintentionally when the vehicle experiences a severe road vibration, such as travelling over a highway rumble strip at highways speeds. This severe vibration may cause air to pass through the solenoid valve, resulting in increased air pressure to the control port and potentially causing the dash-mounted park brake valve to pop out, causing an unintended park brake application without brake light illumination. This could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will replace the auto-park solenoid valve and its mounting bracket.
