Maserati is recalling the 2018 Ghibli and Quattroporte, sedans very loosely based on the Chrysler 300C platform and architecture, because of a possible fuel leak. Dealers will install a new fuel line kit at no cost to customers, starting roughly February 9, 2018. The recall number is 363 within Maserati and 17V834000 for the NHTSA.

The problem originated with a supplier, not Maserati itself. At any point in the fuel line assembly, dirt on the plastic fuel line portion could cause leaks — at this point, likely minor seepage, which could worsen over time. The entire line appears to be at risk. There may also be a problem with excess peeling of the plastic fuel line end at the quick connectors.

The leaks might be spotted by the car’s environmental protection systems — the evaporation leak detection system could detect a problem, and light the Check Engine light.

The issue affects V8 cars and all-wheel-drive V6 cars; it should take around two and a quarter hours on V6 cars and around an hour and 45 minutes on V8s.

The defect was positively identified on December 14, 2017, and does not affect cars made after that day.  Maserati acted extremely quickly in this case: after two incidents from internal tests, they opened an investigation. One day later, the root cause was found, and two days after that, the supplier found the process issue and identified the problematic parts.
