Chief Wolff certainly hasn't piled any blame at Hamilton for his early crash in Austin, claiming that the car was to blame for the disastrous showing.
Speaking to Sky Sports in the aftermath, he said: "100% car. I think he was not even pushing at that stage.
"We’ve seen it [in qualifying] with George [Russell], and that was maybe over pushing it, but still abruptly losing it, putting it in the wall.
"Today, such a situation, there was wind and there was a little bit of dirty air.
"We definitely have an issue. I don’t know whether it was yesterday the same as today. Definitely Lewis Hamilton doesn’t lose the car like this.”
Hamilton currently sits sixth in the drivers standings after two race wins and four podium finishes this year.
While Mercedes find themselves fourth in the constructors standings.
