Volvo Recalls Nearly 2,500 Trucks Due to Steering System Defect

Volvo Trucks North America is initiating a recall affecting approximately 2,487 of its New VN model trucks, encompassing both 2025 and 2026 model years. According to information submitted to the National Highway Traffic Safety Administration (NHTSA), a defect in the dynamic steering system’s oversteer guidance feature could lead to unintended steering corrections, potentially causing a loss of vehicle control and increasing the risk of a crash.

The issue stems from a software parameter, identified as P1HF9, within the dynamic steering system. This parameter is designed to correct for driver oversteer inputs, but in certain circumstances, it may continue to make adjustments in the opposite direction. These oscillations can create a situation where the driver requires intervention to maintain control of the vehicle. Volvo Trucks North America has determined that insufficient validation of all vehicle variations contributed to this defect. Currently, there are no reported warnings associated with this specific issue, and no accidents or injuries have been reported in connection with the defect.

The recall specifically targets 1,487 units of the 2025 Volvo New VN and 1,000 units of the 2026 Volvo New VN. These vehicles are equipped with the dynamic steering and oversteer guidance system. The identified problem could pose a safety risk, as an ongoing, uncommanded steering correction could lead to a loss of vehicle control without prompt driver intervention, potentially resulting in a crash. The component manufacturer for this system is Volvo Trucks LLC, based in Greensboro, North Carolina.

Volvo Trucks North America has outlined a remedy program to address the defect. The oversteer guidance feature, or Parameter P1HF9, will be disabled to eliminate the safety risk. This correction will primarily be carried out through an over-the-air (OTA) software update for vehicles capable of receiving it. For trucks that cannot be updated remotely or are otherwise inaccessible, dealerships will perform the necessary software correction. The remedy component, in essence, is the recalled component with the oversteer guidance feature deactivated.

Production at Volvo’s factories has been impacted by this issue. A stop shipment order was implemented on August 5, 2025, meaning affected vehicles will not be released until the oversteer guidance has been removed. Future production orders will also be built with this feature already deactivated.

Dealers are scheduled to be notified of the recall by August 15, 2025, and owners will receive notification by October 5, 2025. VINs of affected vehicles will be searchable starting August 15, 2025, allowing owners to determine if their truck is part of this recall. The company is utilizing a general reimbursement plan for any expenses incurred related to this recall. The recall is being implemented in phases, with owner notifications scheduled to commence in October.
