FIA Completes Investigation Into F1 Chaos in Malaysia and Announces Measures
The governing body said teams and engine makers will expand validation after cars lost power on the formation lap and the race was delayed.
- On Sunday, October 4, 2026, the Bahrain Grand Prix in Sepang, Malaysia, faced significant delays after a software bug caused several cars to lose power during the formation lap, leaving drivers stranded on track.
- Investigators found the issue stemmed from a 250kW power restriction applied during wet-weather races, which caused the car's electric motors to enter lock-down mode when drivers adopted a cautious approach.
- Drivers criticized the "software bug," prompting the FIA to issue an emergency update to all teams before the race eventually restarted over an hour later than originally scheduled.

- A more permanent software update will follow for the United States Grand Prix, incorporating independent assessments to ensure greater reliability for the complex 2026 power units.
