April 3 (Reuters) - Chrysler-parent Stellantis ( STLA )

said on Thursday it is idling a plant in Warren,

Michigan, for several weeks due to a shortage of engines.

It said the issue is unrelated to new U.S. auto tariffs.

The automaker said it is allocating all available engines to

support production of the Ram 1500 at the Sterling Heights

Assembly Plant in Michigan. The Warren plant will halt

production on April 14 and is expected to resume normal

production in early May, the company said.
