Former F1 World Champion Nico Rosberg has cast doubt over whether Ferrari have got on top of the reliability concerns that have plagued them so far in the 2022 season.
After 12 races, both Charles Leclerc and Carlos Sainz have suffered two mechanical retirements this season, with Leclerc notably suffering costly component failures while leading races in Spain and Azerbaijan.
Sainz’s most recent DNF was a spectacular engine failure at the Austrian Grand Prix, resulting in him having to start 19th at the French Grand Prix after exceeding his permitted usage of several components.
Ferrari customer teams Haas and Alfa Romeo have also been struck with reliability issues related to their power units, prompting Rosberg to question whether Ferrari could iron out these problems in a hurry.
"I'm sure they've learned from what happened in Austria," Rosberg told Sky F1.
“But with an engine, it's often not so easy to bring a quick fix, and I've heard that within Ferrari, it's not easy to bring in this quick fix, so they're trying to manage the situation carefully, but there are some headaches remaining there.
"As we've seen for the whole year, this reliability concern has been the biggest problem for their championship fight.
"[It remains] to be seen if they manage to get it under control or not."

Ferrari failures affecting title hopes
Following Leclerc's spin into retirement while leading last weekend's French Grand Prix, the Monegasque is now 63 points behind championship leader Max Verstappen, who benefitted from Leclerc's DNF at Paul Ricard to take his seventh win of the season.
In the Constructors' Championship, Ferrari are 82 points behind leaders Red Bull, and only 44 ahead of third-placed Mercedes, who have remained within striking distance of Ferrari thanks largely to their superior reliability.
