Owner report 11530344 · 2023-07-04 (July 4, 2023)
I entered a large, strip mall parking area and was driving at the vastly reduced speed one would use in such a situation. My intention was to park my car to enter a store in the mall.

As I entered a parking space (moving at the speed one would drive to do so; essentially INCREDIBLY slowly; moving forward into the space at almost 0 MPH and already applying the brake). Suddenly and with no warning, the car violently lurched forward at a vastly increased speed. I…

Owner report 11442218 · 2021-12-01 (December 1, 2021)
Certain 2018+ and all later Toyota Prius C modes have a 12V battery for which there is currently no OEM or aftermarket replacement. The battery has a form factor (shape and size) that is exclusive to these vehicles and not used in any other car sold in North America. Vehicles with failed batteries (like mine) cannot be operated. Toyota should retrofit these cars to accommodate the battery used in early (pre-2017) model cars which is electrically identical and available as an aftermarket replacement item.
