Sepang software glitch delays F1 start by about 50 minutes
A software glitch left cars stuck in idle during Sepang’s planned formation laps, causing a roughly 50-minute interruption to the start procedure for the Bahrain Grand Prix in Malaysia. Bearman and Sergio Pérez described unresponsive throttles, while Oscar Piastri said it would be unfair to assign blame before an explanation.

Software problems at wet Sepang left drivers stuck in idle mode at points during the two planned formation laps, causing a roughly 50-minute interruption to the start procedure for the Bahrain Grand Prix in Malaysia.
Motorsport.com reported that the bug involved very low speeds and the power-unit controller’s wet-weather mode. It said the FIA delivered a software patch for all 11 teams to install during the following red-flag stoppage.
Max Verstappen said he had triggered the issue first. He said he saw eight other cars still crawling after a lap.
Oliver Bearman said his throttle pedal stopped working while the engine idled, and described the experience as scary. Sergio Pérez, a Cadillac driver in one of several affected Ferrari-powered cars, said pressing the accelerator produced no response. He called the incident unacceptable for the sport but said he was sure the sport would learn from it.
The responses included criticism of F1’s technology as well as caution over blame. Fernando Alonso said the series now involved too much technology and felt spectators did not really appreciate it. Oscar Piastri said he was stuck for about a second and found the episode bizarre, but said it would be unfair to assign blame before an explanation.

Sepang software glitch delays F1 start by about 50 minutes
Correction: Clarified that the roughly 50-minute software interruption was separate from the earlier rain delay. The Dutch wording now states that affected cars could not accelerate. Shortened Verstappen’s account. This is an AI-assisted editorial correction based on source review.
