Force India is still unsure of the cause of the suspension problem that led to Sergio Perez's crash during Formula 1 practice at the Hungaroring, as the investigation continues into the night.
Perez suffered a failure in the right-rear suspension on the run out of Turn 11, which pitched him into the barrier on the inside of the track.
He then rebounded and rolled after the right-front wheel folded under the front of the car and pitched him into the air as a result of damage suffered in the impact.
Force India parked the other car of Nico Hulkenberg for the rest of the first session and also opted to sit out second practice.
It is still examining the failure before confirming its return to the track tomorrow.
"We are still trying to find out," said Perez an hour after the end of practice.
"We can see on the video that the rear suspension kind of bent out, so we are still analysing with the factory to make sure that we can run for the next days.
"When I look back into Turn 9, I had a little bit of a snap but I think it was just because of the overheating of the tyres and a lack of grip and they [the team] can't see anything in the loads there.
"We can see from the video that there is some strange movement on the upper [part] of the suspension but we haven't confirmed what has happened and are still working to see what the real issue is."
Perez, who suffered no injuries in the accident and will be fit to return to action this weekend, has no concerns about car safety if the team does give the green light to continue running.
"They are working on that solution," he said. "My trust is 100 per cent in the team.
"If they decide that we run, then we are ready."
Perez added that F1 should investigate the fact that the car rolled as a result of the deranged wheel folding under the car.
This is partly a consequence of wheel-tether technology designed to prevent the wheel running free, which Perez stresses is something that F1 is right to ensure does not happen.
"What happened to me is something we can learn from," he said.
"We should definitely analyse my accident and see if there is something we can improve, but you don't want to have [loose] wheels going around the track."
