Porsche is close to fixing the fault that provoked engine fires in the 911 GT3. The automaker says:

“We know the reason and the problem-solving measures. We’re testing them,” Porsche CEO Matthias Mueller was quoted by Bloomberg at a press conference on Friday.

He said Porsche will be more specific once a solution has been found. He added that the carmaker will announce the technical solution “shortly” and will first inform customers.

Porsche recalled all 785 units of the 2014 911 GT3 last month after two vehicles caught fire in Switzerland and Italy following engine failures.
