Well-known Stellantis executive Tim Kuniskis is returning to the automaker effective immediately, CNBC has learned.

Troubled automaker Stellantis has decided that its Ram brand needs its own executive, so it is bringing back an executive who retired this year when CEO Carlos Tavares was still running the company.

Tim Kuniskis, former head of Dodge and Ram, is returning to Stellantis to lead the Ram Trucks brand, effective immediately, according to sources. His return follows the unexpected resignation of Stellantis CEO Carlos Tavares last week amid struggles in the North American market.
