ELECTRICAL SYSTEM:WIRING

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.

What the ratings mean
NHTSA gives the 2018 Toyota Prius 5 out of 5 stars overall, level with the 5-star median for the 16 comparable 2018 vehicles NHTSA rated in this class.
NHTSA published results for every NCAP test in this program, so the overall star rating rests on a complete set of crash and rollover results.
NHTSA's dynamic test put this vehicle's rollover probability at 10.7% in a single-vehicle crash — the figure behind the rollover star rating, published here because the star alone hides how wide each band is.
