MILAN — Stellantis is facing production disruptions at its Italian plants due to a shortage of an electronic component used in an engine control unit, with the problems potentially continuing through December.

The shortage affected October sales, particularly of the Fiat Pandina minicar, one of the brand’s best-selling models, Stellantis said on Nov. 2.

The automaker said the shortage could lead to further production problems, including temporary shutdowns, in November and December at the Pomigliano plant, where the Pandina is built, and at Mirafiori, which produces the Fiat 500 Hybrid.

The disruption could also affect Italian plants making engine components, including Termoli, where the 1.0-liter, 3-cylinder N3 GSE engine used in both models is assembled.

“Stellantis and Fiat are working with the highest priority to identify alternative solutions and gradually restore normal operations,” the company said.

Mirafiori is already undergoing a three-week production halt that began in mid-October because of a separate component shortage. Unions have also cited weak demand for the Fiat 500 as a factor behind the stoppage.
