Seven problems related to car stall have been reported for the 2012 Toyota Prius. The most recently reported issues are listed below.
On 09/19/2019 key west Toyota completed the tires change of my vehicle as I requested. In addition, key west Toyota performed "107649 j0v recall j0v01b 0. 70 update to the power management ecu with new software" as showing on the invoice. The following day, on Friday 09/20/2019, while I was driving the vehicle lost power and stalled in the middle of the traffic, putting my life and safety at risk and my heath and general well-being. I sent back the vehicle to key west Toyota, and since then the issue is unresolved, and I am not even able to reach anyone on the phone or through the email I sent from key west Toyota website "contact us".
Tl the contact owns a 2012 Toyota Prius. While driving at unknown speeds, the vehicle stalled and all the indicators illuminated on the instrument panel. The vehicle was towed to della Toyota (32 della dr, plattsburgh, NY 12901), but a diagnosis was not provided. The vehicle was not repaired. The manufacturer was not notified of the failure. The VIN was not included in NHTSA campaign number: 18v684000 (hybrid propulsion system). The approximate failure mileage was 91,000.
When I brake the car shakes a noticeable type of shake and starts to make a weird stalling noise.
Car stalled on highway. Was just merging onto highway, the car stalled and died. Was able to very, very slowly pull off to the side of the road . This was a few months after the software update for the inverter. Could have been a catastrophic accident!!! got towed to a Toyota dealer. They replaced the inverter and parts with an updated one and software too. There was no charge to me. However, I believe the 2012 inverter was inferior and all these models should be updated with new inverters. This is an accident waiting to happen!.

After Toyota power management software recall installed "power management upgrade" software in my car I immediately experienced serious problems with my ignition /start of hybrid/gasoline engine. After pressing ignition, I had to wait 15 to 20 minutes and press start button on/off repeatedly until the gasoline engine ignite but hybrid failed to start. It is not normal because a Prius hybrid engine starts first not the gasoline engine. Toyota has disabled some important functions in its power management recall software update that affects the hybrid engine performance and failure to start. I drive my Prius 3-4 times a month and I did not have any problem before the recall software upgrade because Prius owners manual clearly says that the battery with be disconnected by battery saving function when your car is parked for long time, several days, weeks. In fact, when your car is parked for just days, Toyota power management software (recall) is draining the car battery and reconfiguring the relays to power up the gasoline engine. Toyota owners manual clearly states that when you are parked, "power management software disconnects the auxiliary battery from the hybrid system. " however, after the recall, not only auxiliary battery is not disconnected but there are lots of "activity" in hybrid engine that drains the batteries. I called the Toyota service and they now say you have to keep the car on a charger all the time when parked for several days. Of course , it is a huge safety problem to keep the car on a charger all the time when parked for days because the battery is housed in the cabin and the ventilation does not exist unless you park your car outdoors. At the same time Toyota recommends keeping the car on a charger , it also warns of explosion caused by charging the batteries in a garage.
At least 2 or 3 times a week, when shifting the car into drive when the car is stopped, the car goes into reverse instead. The first few times I thought I had made a rushed error, so I started watching quite carefully. You can even be backing up and then brake and shift the car specifically into drive and it stays in reverse. It might take 3 or 4 attempts to get it into drive. I have realized this must be why they installed the beeping in the system to alert you that the car is in reverse, it must be a more pervasive problem than simply in my car. I always visually confirm my motions now, and 2 or 3 times a week I will enter the car and put it in drive and it goes into reverse instead. This is an accident waiting to happen.
