Daimler Trucks North America is recalling 3,691 Freightliner trucks and other vehicles to correct defects that could affect their ability to brake, the National Highway Traffic Safety Administration reported Monday.

The manufacturer is recalling 702 Freightliner M2 Business Class, 108SD, 114SD, and Columbia trucks produced between Jan. 6, 2010 and Feb. 29, to fix the rear disk brake caliper.

Poorly installed calipers could come into contact with the vehicle’s spring suspension, creating a crash risk.

“Incorrect caliper orientation resulting in contact with the suspension may reduce brake effectiveness,” the NHTSA said. “Reduced brake effectiveness could lead to a vehicle crash.”

The German auto and truck company also is recalling 2,989 recreational vehicle chassis with a faulty brake activation signal.

When combined with a towing device, the brake activation signal could remain active even when the vehicle chassis service brakes are released. The brakes on a towed device could then remain engaged, increasing the risk of an injury and collision.

“The brakes would drag and possibly overheat potentially resulting in a fire,” the NHTSA said. “Additionally, following drivers may be confused by the motorhome’s actions, increasing the risk of a crash.”

The recall affects 2013-2016 FCC XCS, XCM, XCR, XCL, XCP, XBS, XBR, and XBP trucks built with a heavier, adjustable foot pedal, and manufactured between Jan. 7, 2013 and June 1, 2015.

No crashes or injuries related to either defect have been reported.

Both recalls are expected to begin in early June.
