2026-03-10, Power Train
On at least 4 occasions when the EV battery becomes depleted while driving at highway speeds and the car is switching to gas, the engine completely loses all power. This has lasted from 10-30 seconds. The dealership said a small battery needed to be replaced, and replaced that, but this recurred within a month of replacement.

There has been at least 4 times that the vehicle was not responsive to acceleration (stalled for a few seconds) then picked back up. Problem has been intermittent. There is no dash indication of an issue. Because concern is intermittent I haven’t taken vehicle in. There is NO CHECK ENGINE light on. My wife experienced it once, I’ve experienced it 3 times. Once going up steep hill, once on a steady incline and the other 2 times at 50 mph on the highway. My layman’s take points to an Inverter issue in the IPM. Intelligent Power Module having a voltage issue that causes vehicle to stall.

Hi, My Prius Prime recently just suffered the loss of heat in the middle of winter. Based on the diagnostic of my local Toyota dealer, it appears one of the metal heater coolant hose had rusted off. This is not just causing a safety issue of having no issue, it is also a risk as the engine can now overheat and suffer permanent damage. Despite being such a serious problem, Toyota doesn't stock the part nor does it know when the new part will come. I am currently owning an asset that can't be safely driven, I would like the NHTSA to review this. Toyota seems to be aware of this issue as they have a TSB out on a similar heater coolant hose. With that said, having no part is not an accept

As I was driving on a local highway going approximately 50 mph, the hood of the vehicle released and hit the windshield with full force. Luckily there was no traffic on the local highway at the time of the incident. I did not release the hood at all, and the dealer reports verbally to me that the hood latch is damaged. The incident could have resulted in my death if it happened on the highway.

My 2018 Toyota Prius Supreme was parked too far away from the curb in front of a house where we were invited, in a residential area in Naperville IL. I entered the car to park it properly. I had my foot on the brakes and pressed the starting button for the engine to turn on. I then put the car on reverse and suddently the car accelerated uncontollably. Went on the grass, hit the neighbor's mailbox and stopped by crashing on a tree. I was in shock but luckily not injured. Other guests were present and witnessed the incident. Police was called in and issued a report. The car was declared by Progressive Insurance Co as a total loss.
