Volvo Trucks North America is recalling 3,175 model year 2014-2015 VAH, VNL and VNM trucks.

According to a National Highway Traffic Safety Administration bulletin, bolts holding the disc brake caliper to the backing plate may not have been tightened to the specified torque. This could cause the disc brake caliper to detach from the backing plate. If that happens, it can affect the brakes to that particular wheel, causing the vehicle to "pull" to the left or right, increasing the risk of a crash.

Volvo will notify owners, and dealers will inspect and tighten the bolts to specification, as necessary, free of charge. The recall began October 10.

Owners may contact Volvo customer service at 1-800-528-6586. Volvo's number for this recall is RVXX1403.

Meantime, a second Volvo Trucks recall involves a far fewer number of trucks. Nearly 50 model year 2015 VNL and VNX trucks equipped with a Volvo D16 engine may suffer from the engine control unit having an incorrect parameter setting in the software, which could lead to the engine stalling and increase the risk of a crash, according to NHTSA

Volvo will notify owners, and dealers will update the engine control unit software, free of charge. The recall is expected to begin in November.

Volvo's number for this recall is RVXX1404.
