FCA US LLC, formerly Chrysler Group LLC, said on Sunday it was recalling a small number of new Chrysler sport utility vehicles that may have been equipped with improperly heat-treated suspension components.

FCA said it had advised around 65 U.S. owners of new Grand Cherokee and Dodge Durango SUVs to stop driving their vehicles, and that around 7,690 additional vehicles were also subject to recall, but most of those were not yet in service.

The company said the problem could lead to component breakage, rear-end instability and/or reduced braking power.
