Aston Martin Valkyrie: brakes overheat on track and risk catching fire

Aston Martin is recalling its rarest 2024 Valkyrie hypercars in the United States. NHTSA campaign 26V359 covers just seven cars, but the issue is no minor inconvenience: under hard track use, the brakes can overheat to the point of catching fire.

The recall targets Valkyries fitted with the track suspension. Under certain conditions, a seal inside one of the master brake cylinders deforms, and fluid in the diagonal brake circuit no longer returns to the reservoir after the pedal is released. Pressure remains, the pads stay pressed against the discs, and temperatures climb. If the discs are already hot and the driver keeps attacking the track, the resin in the carbon rear brake-cooling ducting can reach its ignition point.

The scenario doesn’t resemble an ordinary street fault. Aston Martin notes that the conditions arise only on track: high lateral g-force, slides or drifts, ESP intervention, aggressive throttle work, and sharp braking at the moment the circuit is already pressurised. On public roads such slip angles and speeds simply aren’t reachable.

The root cause runs deeper than one component. The original master cylinder design wasn’t engineered to handle ESP and the adjustable traction control operating simultaneously in that mode. The supplier is listed as Alcon Components, and the new cylinders will use a different piston and seal. The fix takes up to five hours, is free of charge, and owner notifications go out in June, with the full repair expected in November 2026.

The rarest recall isn’t always the quietest: seven cars were enough to expose a problem at speeds where ordinary cars simply don’t go.
