Formula 1 investigates software bug causing Bahrain GP start chaos in Malaysia
Formula 1 officials announced a full investigation into a software glitch that disrupted the start of the Bahrain Grand Prix at the Sepang circuit on Sunday, October 5, 2026.
Investigation launched after power loss
The FIA confirmed it will conduct a full review of the software-related power loss that affected multiple cars during the formation lap. Several drivers experienced dramatic slowing or complete stops while heavy rain delayed the scheduled start by forty minutes.
Technical causes identified for glitch
An unprecedented combination of low engine speed, wet-weather energy management settings, and track configuration contributed to the cars losing power. The governing body stated that neither the FIA nor teams detected this issue during prior testing or laps to the grid.
Software update distributed mid-race
The FIA Technical Department removed energy limit constraints in affected sectors through an updated software release sent to all competitors. This change allowed teams to make necessary adjustments to their Power Units before the race resumed after the delay.
