The Haas driver has earned a reputation for complaining vociferously on the radio about his car and rivals.
In Austin, Grosjean asked to retire the car in the closing stages due to suffering tyre problems, and was interrupted during one tirade by team boss Gunther Steiner who told the Frenchman to “shutup”.
When asked about it, Grosjean said in Mexico: “I will not comment on anything.
“We solved the problem and everything is now in order.
“I will only say this — if you summarise everything I said over 30 laps in one video, it sounds very sharp.
“So I was a little shocked when I heard it because it was actually quite different.
“At one stage I was afraid for my safety, because one of the tyres was completely worn out and the team didn’t know because the sensor didn’t work,” Grosjean explained.
“But I have since discussed everything with Gunther,” he added.
Grosjean’s team radio messages
Grosjean: “Mate what was that? Seriously. I don’t know if I… I think we should retire the car. I think we should retire the car, no point in going to the end. I can see the whole [censored] left tyre. What are we doing, guys? Seriously.”
Team boss Gunther Steiner: “Shh… Shut up.”
Grosjean: “You’re not paying your life here. The tyre is completely gone. ”
Engineer: “OK dude so we’ll box to retire the car, retire the car. Box now. It’s the last lap anyway, man, but just bring it in easy.”
Grosjean: “I can go the chequered flag if you want, but…”
Engineer: “Yeah we’ll just take the chequer.”
The talk is included in F1’s recent team radio round-up
