Although the involved vehicles are within the above production period range, not all vehicles in this range were sold in the U.S. This issue only affects 2023-2026MY Prius and Prius Prime vehicles equipped with electric rear door lock system with a door opener switch manufactured by a specific supplier and during a specific production period.

Since Nov 23, 2024 I have had three occasions where the 12 volt battery for the ICE has depleted leaving me stranded. The only indication of the problem is the car will not start. In my last incident I had to charge the battery (disconnected from the car) but inadvertently closed the hatch. Since the car uses electronic locks the only way to open the hatch is to use the emergency release that is located under the rear deck and must use a screw driver to release. This is inherently dangerous since no practical escape possible in an emergency.
