GREENSBORO, N.C. – Volvo Trucks North America agreed to recall certain model-year 2020-2023 Volvo VNR Electric vehicles due to an issue with their adaptive cruise control systems causing over-aggressive braking which could lead to an out-of-control situation.
The 236 vehicles in the recall population are equipped with the adaptive cruise control “enabled.”
According to the National Highway Traffic Safety Administration Part 573 Safety Recall Report 23V-255 the recalled vehicles could “During an adaptive cruise control braking event under light load conditions, regenerative braking could be aggressive with the potential of locking brakes and alternating anti-skid braking events, skidding the rear axle.”
Should such an event occur, the driver could lose control of the vehicle, which could lead to a vehicle crash. NHTSA also reported there is no warning this might occur.
There have not been any incidents, accidents or injuries associated with this issue.
The cause has been pinned as “Adaptive cruise control was enabled without sufficient systems integration and software tuning,” according to the report.
The remedy includes removing any components which may have been installed on the vehicles which could cause the safety defect. Disabling the adaptive cruise control functionality within the anti-lock braking (ABS) electronic control unit to prevent the adaptive cruise control function on these vehicles.
Dealers were scheduled to be notified as to the recall last week and owners are scheduled to be notified by June 2nd.
