Details
What's wrong: 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.
Why it matters: An electrical short can increase the risk of a fire.
The fix: Toyota will notify owners, and dealers will inspect the engine wire harness assembly and replace it if damage is found. A protective sleeve or protective tape will be included to prevent any future damage. These repairs will be performed free of charge. The recall began October 30, 2018.
