Hadjar reports no power at US GP as engineer describes 40% throttle dead zone

Isack Hadjar repeatedly told his engineer he had no power during the United States Grand Prix.

Hadjar questioned why he was on hard tyres. His engineer said the hard tyre was the right choice at that point and told him the team was racing Piastri. As Hadjar continued to report no power, the engineer instructed him to change settings and press the boost button. Hadjar asked whether the team could see the problem; the engineer said they could. Hadjar later reported an error message on his steering wheel.

The engineer then said the hard tyre appeared to have good pace on the McLaren. He went on to explain that the accelerator had a large dead zone and responded only from 40% pedal input. The team could do nothing about it during the race, he said.
