2017 Toyota Prius Prime

The contact owns a 2017 Toyota Prius Prime. The contact stated that while driving at an undisclosed speed, the vehicle stalled. Several unknown warning lights were illuminated. The contact stated that while attempting to start the vehicle, the vehicle started. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The contact used a portable diagnostic machine to diagnosed the vehicle; however, no fault codes displayed. The contact stated that the failure had not reoccurred. The contact referenced an unknown recall; however, the VIN was not associated with a recall related to the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,000.

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.

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.
