Nico Hulkenberg has escaped punishment following hs collision with Daniel Ricciardo in the United States Grand Prix after Force India proved he had suffered a mechanical failure into the hairpin.

Hulkenberg was attempting to wrest fifth from Ricciardo on lap 36 when he slid wide into him, breaking his suspension and putting him out of the race. Though Ricciardo continued, the clash was placed under investigation by the stewards.

However, the team would be able to prove that Hulkenberg was contending with a front-wing issue prior to the clash, with it proceeding to break just as he was passing the Red Bull driver.

"No further action is warranted due to a mechanical failure on the car in the braking zone at turn 12," read an FIA statement. "The front wing became visibly dislodged at the braking zone affecting the stability of the car and the ability of the driver to effectively brake for the corner, resulting in collision with car three."

Hulkenberg has now failed to finish three of the last four races.
