Toyota Recalls Prius Vehicles With Shorting Engine Harness

The shorting harness could generate excessive heat, which may result in a fire

September 11, 2018

Toyota Motor Engineering & Manufacturing (Toyota) is recalling 192,347 model year 2016-2018 Toyota Prius vehicles.   A portion of the engine wire harness connected to the hybrid Power Control Unit (PCU), could contact the cover at this connection and wear, causing an electrical short circuit.

What's the problem?

The subject vehicles have an engine wire harness which is connected to the PCU. The wire harness has a cover attached at this connection. Due to assembly variation, a portion of the wire harness could contact the cover. If dust has accumulated on the wire harness or the cover, vibration during vehicle use may cause the insulation on the wires to wear over time and expose the core wire, causing an electrical short circuit and heat generation to occur between the damaged wires. If sufficient heat is generated, there is an increased risk of a vehicle fire.

What happens next?

Dealers will check the engine wire harness assembly. If a wire core is exposed, the engine wire harness assembly will be replaced with a new one, which includes a protective sleeve. If a wire core is not exposed, protective tape will be installed on the engine wire harness assembly.
