Volvo Recalls Over 12,000 Electric and Hybrid Cars Due to Brake Control Software Glitch Threatening Safety

Volvo Cars has announced a large-scale safety recall affecting more than 12,000 plug-in hybrid (PHEV) and battery electric vehicles (BEV) from model years 2020 through 2026. The recall is due to a software defect in the brake control module that may cause temporary or complete loss of braking capability, posing a significant safety risk to drivers and passengers.

Technical Details of the Problem

The software issue involves the Brake Control Module, specifically a fault in software version 3.5.14. This glitch can cause brake loss during certain driving conditions, particularly when using the “one-pedal drive” mode in electric vehicles or the “B” mode in hybrids.

The problem typically occurs when a driver coasts down a long slope for at least one minute and 30 seconds without pressing either the brake or accelerator pedals. In this scenario, the brake system may lose responsiveness. If the driver then presses the brake pedal after this loss, the brakes may completely fail, greatly increasing the risk of an accident.

Incident That Exposed the Issue

On May 13, 2025, a Volvo XC90 Recharge PHEV owner experienced a serious accident on a narrow mountain road in California while using the “B” driving mode. The driver had recently received a software update at a local dealership just hours before the crash. During descent, the driver lost brake control and had to steer off the road to avoid plunging down a steep cliff.

Dashcam footage and vehicle data logs confirmed that although the brakes were applied, the car continued accelerating uncontrollably. The accident caused severe damage to the vehicle, including a broken front wheel and tire blowouts, and deployed some airbags. Fortunately, no serious injuries were reported.

Volvo’s Recall and Repair Measures

In response to this incident, Volvo issued an official recall for all affected vehicles to receive a free software update for the brake control module. The recall notification began on August 6, 2025, advising owners not to use the “B” or “one-pedal drive” modes until the update is installed.

The recall covers multiple Volvo models, including:

• XC90 PHEV (2020-2025)
  
  

• XC60 PHEV (2022-2025)
  
  

• S60 PHEV (2023-2025)
  
  

• V60 PHEV (2024-2025)
  
  

• S90 PHEV (2025)
  
  

• XC40 BEV, C40 BEV, EC40, and EX40 (2023-2024)
  
  

It also includes some vehicles that had previously received updates for rearview camera issues and may require additional updates to prevent brake-related problems.

Importance of Software Updates and Following Recommendations

Volvo emphasizes the critical importance for all affected vehicle owners to install the new software update either via online download or by visiting an authorized dealer. Ignoring this update could expose drivers to sudden brake failure, which could lead to serious accidents.

The company also advises drivers to avoid using “B” or “one-pedal drive” modes, especially on mountainous or steep roads, until the update is applied.

Customer and Expert Reactions

Some customers who experienced the issue expressed frustration over the delay in identifying the problem, especially after encountering dangerous situations on the road. Others praised Volvo’s swift response and recall, noting the company’s commitment to safety.

Automotive experts point out that this problem highlights the challenges faced by modern vehicles with complex electronic systems that heavily rely on software to manage critical safety functions.

Comparison with Previous Recalls

This is not Volvo’s first recall related to software affecting safety systems. In recent months, the company recalled over 410,000 vehicles due to rearview camera malfunctions that could increase the risk of rear collisions.

The current recall underscores the importance of rigorous software testing before release, especially in electric and hybrid vehicles that depend on advanced control technologies.

Advice for Drivers

• Regularly check for software updates for your vehicle and maintain contact with authorized dealers.
  
  

• Follow manufacturer recommendations regarding driving modes and avoid using “B” or “one-pedal drive” on slopes until updated.
  
  

• Be alert to any changes in brake performance or vehicle response and seek immediate inspection if issues arise.
  
  

• Maintain regular vehicle servicing, especially for electronic and braking systems.
  
  

Volvo’s recall of over 12,000 electric and hybrid vehicles due to a brake control software defect serves as an important reminder for owners of modern cars that rely on advanced technology. The issue, which can cause temporary or total brake loss under specific conditions, has been addressed promptly through a free software update.

Adhering to updates and safety recommendations remains the best way to ensure driver and passenger safety and prevent potential accidents caused by technical faults.
