The official notice
Defect
Volvo Trucks North America (Volvo) is recalling certain model year 2012-2016 VNM trucks manufactured March 21, 2011, to April 30, 2015. Excessive engine crankcase pressures may cause the 90-degree elbow of the vent tube assembly to detach from the crankcase ventilation breather, possibly allowing engine oil to come into contact with hot surfaces.
Safety Risk
If engine oil comes into contact with a hot surface, there could be an increased risk of a fire.
Remedy
Volvo will notify owners, and dealers will secure the ends of the 90-degree elbow. In addition, the electronic control module (ECM) will be reprogrammed with software that can adjust the engine output under misfire conditions to limit crankcase pressures. These repairs will be performed free of charge. The recall began on June 12, 2015. Owners may contact Volvo customer service at 1-800-528-6586. Volvo's number for this recall is RVXX1502.
