The Monegasque driver endured a difficult Saturday as he struggled with a mystery problem on his SF-23 that left him getting dumped out in Q1.
Speaking after the session, Leclerc said the issue seemed worse on left-hand corners.
“During the red flag, I was at 70km/h and there was just no warning,” said Leclerc, who ended up qualifying 19th.
“The left-hand corners were really bad with the rear-right, and I thought it was the tyres. So, we went for a new set of tyres. But on the new set, it was exactly the same feeling – right-hand corners were really good, and left-hand corners were completely off.
“We’ll have to check, but I would be very surprised if we don’t find something on the car.”
Parc ferme restrictions on Saturday night meant Ferrari was unable to conduct a deep analysis of Leclerc’s car until this morning.
However, the team has already decided as a precaution to replace the entire rear of Leclerc's car – which includes suspension and gearbox.
