Software Bug Triggered Bahrain Grand Prix Red Flag

Software bug
A software bug turned the Bahrain Grand Prix formation lap into a start-line mess and forced race control to abandon the launch, send the field back to the pits and reset the race under a red flag. Several cars lost power, crawled or stopped altogether as the glitch affected multiple cars, and the FIA software update that followed took nearly an hour to sort out. Max Verstappen briefly lost acceleration while running at the front, but his problem was fixed after a steering-wheel change. Lewis Hamilton also lost power, then got his Ferrari running again by switching the car off and restarting it. Charles Leclerc and Lando Norris each dealt with low-power failures, too, adding to a scene that kept changing as the field tried to figure out what was happening. Andrea Kimi Antonelli initially looked unaffected, but engineers later realized the issue was reaching multiple cars instead of staying confined to one team. The opening sequence never settled into a normal rhythm, and multiple cars were pulled into the same malfunctioning chain of events before the race could get going.
Race control
Race control chose the red flag once the start unraveled, then reorganized the grid after the field had been sent back to the pits. The move came after several cars had already slowed or stopped during the wet formation lap, and the restart process had to wait until the FIA software update was complete. That left the session in limbo while officials worked through a problem that had affected multiple cars. Verstappen’s brief loss of acceleration was handled with a steering-wheel change. Hamilton’s Ferrari needed an off-and-on restart. Those fixes solved individual problems, but they did not explain the wider collapse that had already forced the stoppage. The incident showed how quickly a software failure can take over a Grand Prix start, because race control had to stop the process entirely before the race could be organized again. Once the update was in place, the field could be reset, but only after a long delay that left the opening sequence of the Bahrain Grand Prix as much about recovery as racing.
Driver reactions
Fernando Alonso questioned the red flag after Hamilton and other drivers ran into power unit software issues during the wet formation lap, and he called the aborted start “a bit weird” because only some cars were affected. Alonso also said Hamilton’s stoppage in the gravel seemed to trigger extra concern from officials. Before the restart, he had been told he could pass slow cars while the field dealt with the problem, a sign of how disjointed the opening moments had become. Nikolas Tombazis, the FIA single-seater director, later said the chaos was caused by a software bug, putting an official label on the problem that had already affected multiple cars. Carlos Sainz took the discussion in another direction, saying the issue was predictable because Formula 1 relies too much on software and race-control intervention. Between the stalled cars, the restart delay and the drivers’ questions, the Bahrain Grand Prix opened with a reminder of how quickly a software problem can disrupt a Grand Prix start.
