Stellantis warned that a supplier shortage could constrain Fiat production at two Italian plants during November and December after affecting the brand’s October volumes and market share.
The shortage involves a component for the N3 GSE engine control unit. Stellantis did not identify the part or its supplier, and gave no estimate of lost production or the decline in Fiat’s October volumes. The company said the constraint also affected Fiat’s results so far in 2026, particularly the Pandina, but provided no year-to-date impact figures.
Stellantis said the effects could persist at Pomigliano d’Arco and Mirafiori during November and December. Reduced output could also prompt temporary suspensions at Italian plants that make engine components. The company did not specify which facilities could be affected or how many workers might be involved.
The Pandina recorded 86,000 registrations in Italy from January through September 2026, up 5% from the same period a year earlier, Stellantis said in an Oct. 21 release. It was the country’s best-selling car during those nine months.
Stellantis said it and Fiat were prioritizing alternative options, with a gradual return to normal operations as their aim. The company did not provide a timetable for that process.
Separately, Reuters reported that Mirafiori began a three-week production halt in mid-October because of a different component shortage. Reuters also reported that unions cited weak demand for the Fiat 500 as a factor in that stoppage.
Stellantis gave no date for another update. It said production effects could continue during November and December.
