VEHICLE SPEED CONTROL,ENGINE — Filed 03/15/2026

In the 2017 Prius Prime when the car switches from Electric power to gas the car frequently fails to allow you to accelerate. It is like you are stuck in neutral on the freeway, taking your foot off of the acceleration pedal and pushing it down doesn't always fix the issue. The accelerator foot pedal can be completely down to the floorboard as you are losing speed. The safety issue is that you are losing speed, and on the freeway and the car doesn't recover losing some control. I have taken the car to the Toyota delearship and when taken in that say it is a software update, but this continues to happen. There is no real notification when this will occur as the battery milage switchover is often misreported by the car.

ELECTRICAL SYSTEM,UNKNOWN OR OTHER — Filed 12/05/2025

I have a 2017 Toyota Prius Prime advanced. It has the large infotaiment screen that is where I have to access many items. Often, seemingly randomly, the screen shuts down and reboots itself. During the time it is rebooting I do not have any access to the controls. It gives no warning when it is going to reboot. I have seen other Toyota recalls for a similar problem on the RAV4 vehicles and I wonder if it is related.

During hot temperatures and after coming to a full stop, the car stalls/hesitates significantly (5-6seconds) when pushing the gas pedal. The car eventually proceeds but the issue reoccurs. It can only be intermittently reproduced and no codes are shown on the car dashboard. Mechanics are unable to identify the source of the issue so it cannot be resolved.

Toyota has a very well known issue with head gasket failures right around 140k miles that they refuse to address. This is my second Prius and my second failure right at 140k miles. They refuse to acknowledge it, but the advisors in the service department say that's their "bread and butter." They repair bad head gaskets on priuses for $5k all day long. Toyota needs to do right by their clients.

Background Toyota has received reports of paint peeling on certain vehicles with the original factory-applied Blizzard Pearl or Super White paint colors. These reports indicate that vehicles with these specific paint colors, applied during the vehicle manufacturing process, may experience paint peeling on exterior metal body panels. Although the original factory paint is covered by Toyota’s New Vehicle Limited Warranty for 3 years or 36,000 miles (whichever comes first), we at Toyota care about the customers’ ownership experience. Toyota is providing coverage for repairs related to the condition described above. The following information is provided to inform you and your staff of the program notification schedule and your degree of involvement. Customer Support Program Coverage Details This Customer Support Program provides coverage for involved vehicles with the original factory Blizzard Pearl or Super White paint. The covered condition may occur when sunlight over time degrades the adhesion between the factory-applied paint primer coat layer and the base metal electrodeposition layer causing the paint to peel from the metal body panel. If the condition is verified, the specific panel affected will be repainted. · The Primary Coverage will be offered until December 11, 2022, regardless of mileage. · After the Primary Coverage, the Secondary Coverage is applicable for 10 years from the date of first use, regardless of mileage. My vehicle is a 2017 Toyota Prius prime with Blizzard pearl 070 paint and I am experiencing terrible paint chipping. My hood, roof, and A Pilars are starting to rust. When I tried speaking to Toyota dealerships and corporate about this issue they refused to help and said there's nothing they can do because my vin doesn't match the recall. The fact that this same paint code is showing such wear despite my vehicle being newer that the recalled vehicles should automatically make me a candidate for a paint replacement on the damaged areas.
