Felipe Massa reckons it was an issue with his power unit that put him out of Sunday's Canadian Grand Prix.
The Williams driver was hoping for a strong showing in Montreal as he looked to continue his run of points-scoring finishes.
It was not be.
He retired from the grand prix on lap 37, parking his FW38 in the Williams garage.
"We had a mechanical issue, which was a shame to have," he said.
"I think it was something to do with the power unit.
"The temperatures started to go really high which was not normal because I was not behind anybody.
"They are analysing to see."
The Brazilian lamented the lost points as he reckons Williams could have finished with both cars inside the top ten.
He added: "It was a race where we could have scored points with both cars, but not for me."
