The Haas Formula 1 team has traced Romain Grosjean's front wing failure in the Spanish Grand Prix back to a manufacturing error, Autosport has learned.

Grosjean, who struggled with the balance throughout the weekend at Barcelona, was running 12th when the front wing broke.

It came after two different front wing failures in pre-season testing and Bahrain, and it is understood the latest one was a different problem again.

Following investigations, it has emerged there was a problem at manufacturing level, rather than a design flaw.

Speaking post-race on Sunday, Grosjean called on his team to improve the quality of the front wing and said the team would speak to the department involved.

"We're going to have a word with who's doing it because we've seen the problem and understood why it broke and we need better quality," he said.

"It's all a learning process, we are still new.

"Yes we've had a few problems with the front wing so we're going to work on that and I'm sure it's going to be fine soon.

"We forget a bit that it's only our fifth race."

Grosjean failed to finish a race for the first time this season after reporting he had no more brakes.

The Frenchman, who scored points in three of the opening four races, made a good start and was racing the McLarens for the lower points positions before his race unravelled.

"Before the race I wasn't very optimistic and then after the start and following the McLaren that was faster I had a very good move on [Nico] Hulkenberg," he said.

"So I thought 'actually things aren't looking too bad' and then things went wrong.

"I lost the radio, lost the front wing, lost the brakes.

"Because we've been struggling with the car balance and the hotter the track the harder it is.

"Over a long stint when the tyres are going and the balance is out it's very difficult to manage it."
