Volvo Warns 12,000 Owners to Immediately Stop Using One-Pedal Driving Due to Brake System Fault

Volvo has issued an urgent warning to nearly 12,000 owners of its vehicles manufactured between 2020 and 2026, instructing them to immediately cease using the one-pedal driving system until a software update fixes a critical brake control issue. This step follows the discovery of a software fault that could cause complete brake failure under certain conditions, posing a serious safety risk to drivers and passengers.

What is One-Pedal Driving and Its Importance?

One-pedal driving is an advanced technology that uses regenerative braking, allowing the driver to control the vehicle’s speed using only the accelerator pedal. When the driver lifts their foot off the pedal, the car automatically slows down, reducing the need to frequently use the brake pedal. This system is common in electric and hybrid vehicles, improving energy efficiency and extending driving range.

Details of the Recall and Discovered Fault

The recall, numbered 25V392000, affects several Volvo models including S60, V60, S90, XC60, XC90, XC40, EX40, EC40, and C40 running software version 3.5.14. The problem lies in the brake control unit, which may completely lose braking function when using one-pedal driving, especially after driving downhill for at least one minute and forty seconds.

Volvo states this fault is rare and occurs only under specific conditions such as prolonged downhill driving, which is uncommon on most roads. However, if it happens, pressing the brake pedal could result in total brake failure—the worst-case scenario for any driver.

Volvo’s Response and Actions Taken

Despite the severity of the issue, Volvo plans to fix it via an over-the-air software update, eliminating the need for owners to visit service centers. Notifications have already been sent to affected owners, with all expected to be informed by August 6, 2025.

Volvo dealers have also been alerted to provide necessary support, and owners are urged to stop using one-pedal driving until the update is installed.

Importance of Regenerative Braking and Impact of the Fault

Regenerative braking is crucial in electric and hybrid vehicles, recovering kinetic energy and converting it to electricity stored in the battery, thereby increasing range and reducing energy consumption. It also offers a smoother and safer driving experience by enabling speed control with a single pedal.

The brake control fault jeopardizes this technology by potentially depriving drivers of the ability to slow down or stop promptly, increasing the risk of serious accidents.

Unclear Details About the Investigation

Volvo has yet to release a detailed report on how the fault was discovered, the steps taken afterward, or the rationale behind the recall decision. The U.S. National Highway Traffic Safety Administration (NHTSA) has also not published its final report, leaving some uncertainty about the incident’s background.

Scope of the Recall and Number Discrepancies

Official documents indicate the affected vehicles range between 11,469 and 14,014 units, a relatively large discrepancy. Authorities are working to clarify this variance, and updated information is expected soon.

What Should Volvo Owners Do?

Owners of affected models should immediately stop using one-pedal driving until the software update is applied. They are advised to monitor official Volvo communications and contact authorized service centers to verify their vehicle’s status and receive the update when available.

This incident highlights the importance of continuous monitoring of advanced driving technologies, especially in electric and hybrid vehicles reliant on complex electronic systems. It also underscores the necessity for manufacturers to respond swiftly and transparently when safety-related faults are detected.

Volvo’s prompt warning and recall, coupled with a convenient software fix, demonstrate its commitment to customer safety and brand reputation.
