Volvo Recalls Over 6,000 Trucks Due to Potential Brake Issue

Volvo Trucks North America has issued a recall of certain VNL, VNM and VNX truck models to addess incorrect software for controlling the electronic air dryer that may result in oil and water contaminating the brake system.

The recall affects 6,127 vehicles manufactured from April 11, 2012 through September 30, 2016 with an electronic air dryer. These trucks include VNL and VNM of model years 2013-2017 and the 2017 VNX.

The defect stems from incorrect parameters used to control the cycling of the electronic air dryer. The parameters were set to low at 1/3 of the required volume of air to purge the desiccant. As a result, more condensation may occur and be passed through the air system.

That can allow oil and water to contaminate the brake system, which would affect brake performance over time and in certain conditions, such as cold weather. The repair involves reprogramming the vehicle control module with the correct parameters for the air dryer and may also include replacement of the air dryer filter.

There have been no reports of accidents related to the defect, which was discovered in Oct. 216. After an investigation, Volvo informed the National Highway Traffic Safety Administration that a voluntary safety recall would be conducted to address the issue.

Volvo has already notified dealers of the issue and will mail notifications to owners on or before Feb. 17, 2017. Repair instructions are also tentatively scheduled for release by Feb. 17.
