Aston Martin recalls Valkyrie hypercar due to brake system fire risk

Aston Martin has announced a recall of its Aston Martin Valkyrie hypercar. Vehicles equipped with track suspension may have a seal defect in one of the master brake cylinders. This was reported by Motor1, according to UNN.

Details

The recall affects only seven units of the 2024 model year Valkyrie. If the seal deforms, it can cause a number of problems. Primarily, brake fluid will not return to the reservoir after the brake pedal is released. In such a case, pressure in the braking system will not be relieved.

If enough fluid accumulates, the brakes may begin to make constant contact with the brake disc. Provided the discs are already heated and the car is being operated in an aggressive mode, they could become hot enough to cause the resin in the carbon fiber rear brake cooling duct to ignite.

Fortunately, the problem can only occur under very specific conditions that are virtually impossible to replicate on public roads.

According to the manufacturer, the malfunction can only occur under very specific conditions while driving on a race track: when the car is in a high-speed slide or drift, and the ESP system actively intervenes in the braking process. In this case, due to the simultaneous action of the driver and the electronics, excess pressure can build up in the braking system, leading to brake drag. No warning about the problem will appear, but the driver should feel it through the brake pedal.

Why this is unlikely to happen on the road

The problem is related to the original design of the Valkyrie's braking system. Aston Martin did not initially plan to equip it with ESP or an adjustable traction control system, so the system was not designed for simultaneous brake fluid management via the pedal and electronic systems.

The company first learned of the potential issue in November 2022 and immediately began working with supplier Alcon to determine the causes of the malfunction.

The root cause was identified in February 2025, after which the development of a solution began. Just a month later, the new part was ready.

Installation of the updated component began in September 2025, and in early 2026, a special Aston Martin committee analyzed the data and recommended a recall. At the end of May, the company decided to voluntarily announce a service campaign for safety reasons.

Owners of the affected vehicles will be invited to contact dealerships, where technicians will replace the master brake cylinder with a new modification compatible with ESP and the traction control system. The repair will take up to five hours.

According to the publication, although it took Aston Martin nearly four years to identify the cause of the malfunction, the average driver is unlikely to encounter it due to the extremely specific set of conditions. At the same time, for a car like the Valkyrie, such a scenario is possible, so the company's decision to fix the problem on all seven cars seems entirely justified.
