2024 TOYOTA PRIUS PRIME — Problems, Recalls & Safety Data

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. Other Toyota and Lexus vehicles sold in the U.S. are either equipped with a different electric rear door lock system or do not have an electric rear door lock system and do not have the condition described in this report. Unknown. Toyota is unable to provide an estimate of the percentage of vehicles to actually contain the defect. Whether water enters the door opener switch and causes a short circuit that could lead to a door switch activation depends on various conditions, as described further below. However, as the NHTSA manufacturer portal requires an integer value be entered, Toyota has entered the value “1” in response to this question in the portal. For the purpose of this report, “1” means “unknown”.

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.

The contact owns a 2024 Toyota Prius Prime. The contact stated while driving 65 MPH, the windshield washer and wipers failed to function as intended. The contact drove the vehicle to the shoulder of the road and physically removed mud from the front windshield. The contact stated that an oversized truck hauling mud splashed the vehicle and mud landed on the front windshield. The contact stated that the windshield washer volume and speed was insufficient to clear the windshield. The contact stated that because of the low windshield washer sprayer speed and volume of the washer fluid, the contact feared for his safety. The vehicle was taken to the dealer; however, the failure was not duplicated. The contact was informed that the vehicle operated as designed. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 3,500.
