The Italian Competition Authority has initiated investigations into four electric vehicle manufacturers over alleged unfair commercial practices related to electric vehicle (EV) information provided to consumers.

The investigation of BYD Industria Italia, Stellantis Europe, Tesla Italy, and Volkswagen Group Italia focus on the transparency of data concerning EV driving range, battery capacity degradation, and the limitations of standard battery warranties.

Authorities suspect that the companies may have breached the Consumer Code by presenting unclear or contradictory information on EV driving range without specifying the factors that affect the actual range.

Furthermore, there is concern that the companies have not been transparent about how normal vehicle use impacts battery capacity over time and the specific terms and limitations of the standard battery warranty, the authority said.

As part of the investigation, officials from the Italian Competition Authority, assisted by the Special Antitrust Unit of the Italian Financial Police (Guardia di Finanza), conducted inspections at the companies’ premises.

Stellantis has responded to the investigation, stating that it is fully cooperating with the authorities, reported Reuters.

The firm was cited by the news agency as saying: “Stellantis... is convinced that it has provided adequate, precise and exhaustive answers to the questions posed by the officials.

“Stellantis places the needs and satisfaction of its customers at the centre of all its activities and believes that the ongoing investigation will confirm this.”

Recently, it was reported that Stellantis was planning to produce dual-clutch transmissions for hybrid vehicles at its Termoli plant in Southern Italy.

The Termoli facility had been earmarked by Stellantis-led battery cell joint venture Automotive Cells Company (ACC), which includes partners TotalEnergies and Mercedes.
