Kamui Kobayashi has been cleared by the race stewards of wrongdoing after the Japanese driver hit Felipe Massa at the first turn in the Australian Grand Prix.
Kobayashi hit the back of Massa's Williams but a brake problem meant that the driver was a passenger in a collision which forced both drivers out of the race.
'A serious technical failure completely outside the control of the driver', caused the accident, according to the stewards.
"That isn’t how I wanted my first race back to go, and I’m sorry for the team and for Felipe that both our races ended early," he said.
"I had a really good start but then into turn one I made contact with Felipe.
"From the initial data it looked like I had a brake system issue which obviously meant I couldn’t do much about the contact and when we got the car back and looked at the information in much more detail it was clear that was the problem.
"After the race I went to the Stewards and they went through the data from the car and confirmed this was the case. We’ll have a close look at what caused that problem and make sure we fix it."
