Symptoms Prius Plug-in owners report
- Electric range down from a short commute to a couple of miles.
- The car dropping out of EV mode almost immediately after a full charge.
- Charging stopping early, or the charge indicator behaving inconsistently.
- A hybrid or EV system warning light.
- The car still driving normally as a hybrid while the plug-in side does nothing.
Which capacity to order
The original capacity restores the car to how it left the factory. The higher-capacity option adds electric range, which is worth the difference if you charge at both ends of a short commute and less so if you mostly drive it as an ordinary hybrid.
