Ferrari has ordered a stop of sale on the 488 GTB which was released at the end of 2015. The issue with the 488 GTB is determined by Ferrari to be a fuel delivery issue inside of the engine compartment.
Recently there was also recall on the California T which seems to have the same issue of a low-pressure fuel line that feeds to the fuel pump. The fittings coating treatment on the line seems to be inferior and breaks down to extreme heat and potentially causes fuel vapor leak. This part is not made by Ferrari but one of their fuel system vendors.
