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…

This is a 2024 Toyota Prius prime lease in February 2024. I went to our trusted local car shop for our annual inspection, and was told that we need to replace all four tires and we’re just passed 24,000 miles on our odometer. We are two seniors living in New York State and we only drive on paved roads. We believe this is a failure both of Toyota and Toyota for choosing these tires on this particular model. We were told we need to spend over $1000 to replace tires on a car we do not own. Toyota…

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…

There is an unexplained loss of 12V power from the 12V battery, and the car will not start. This was reported to the local Toyota dealership on 12/5/25.

They said the 12V battery was fully charged when they inspected it and there was no parasitic drain on the the battery. They inspected the battery again on 12/30/25 during a routine scheduled service and the 12V battery was good. We have since experienced the…
