A possible exposed wire on the Toyota Prius has prompted the recall of nearly 200,000 of the hybrid cars.

The safety recall involves certain 2016-2018 model year Toyota Prius vehicles in the U.S.

Toyota says that a section of the engine wire harness, connected to the hybrid vehicle Power Control Unit, could contact the cover at this connection and wear over time, causing an electrical short circuit, which can generate heat.

If sufficient heat is generated, there is an increased risk of a vehicle fire.

Dealers will check the engine wire harness assembly to determine the repair action.

If a wire core is exposed, the engine wire harness assembly will be replaced with a new one that includes a protective sleeve.

If a wire core is not exposed, a protective tape will be installed on the engine wire harness assembly. The repair will be performed at no cost to customers.

All known owners will receive a notification by first class mail starting in late September.
