Kevin Magnussen apologised to Haas immediately after the Canadian Grand Prix for the radio messages which prompted team boss Guenther Steiner to step in and tell him to stop.
In the closing stages of the race Magnussen, who was running two laps behind the leaders, said over radio: "This is the worst experience I have ever had, in any race car, ever."
The Danish driver had started from the pit-lane after Haas was forced into an overnight rebuild of his car following a heavy crash in qualifying. Race engineer Gary Gannon was quick to remind Magnussen of this, before Steiner stepped in to tell him to stop complaining.
