The FIA completed its investigation into the software failures that caused widespread power unit problems during the Malaysia Grand Prix formation laps. Multiple cars experienced complete power loss when a software bug prevented electrical energy redeployment at very low speeds behind the safety car, forcing a race delay of over 90 minutes.
The review identified that cars running on low engine RPM in sectors with 250kW power reduction experienced power loss beyond the original intent that could not be recovered. The emergency solution involved lifting restrictions in affected minisectors where the problem occurred, allowing the race to proceed after teams installed updated software.
The same temporary configuration established for Malaysia will be reinstated for Singapore if similar weather conditions are expected. A more permanent update to the wet-weather software will be released ahead of the United States Grand Prix on October 25, providing a two-stage solution to prevent future incidents.
The FIA dismissed suggestions that the software had not been tested prior to deployment, noting it was validated during Free Practice 1 sessions at the Belgian and Dutch Grands Prix. However, the specific low-speed conditions encountered behind the safety car in wet weather had not been replicated during testing, prompting enhanced validation processes for the future.
