I was driving my 2012 Prius on the highway at around 55 MPH. The Hybrid System Warning came on and the car lost all power and immediately began to coast. I was fortunate not to have been in or caused an accident but cars behind me had to swerve to avoid hitting me. I was able to coast to a middle median lane. After waiting 15-20 minutes, the car never regained power. We were finally able to push it off the road and into a parking lot. It never regained power.

Hi, I have a 2012 Toyota Prius with around 120k miles that is completely inoperable. A local Toyota dealership is charging $3400 to replace both computers, but the more I research the more apparent it becomes that this is directly linked with past issues that were never fully resolved during previous recall attempts. The following article describes the exact situation my car is in (https://www.latimes.com/local/california/la-fi-prius-overheat-inverter-defect-20190414-story.html). When you combine that with the previous recalls back in 2014 & 2018, this quickly becomes a pattern. That pattern suggests that past software issues (1 & 2 below) were never fully resolved, and/or already caused premature damage to internal/computer components that then fail regardless. I spoke with the California Bureau of Automotive Repair who referred me to nhtsa. The agent I spoke with noted that because the Inverter wasn't actually replaced back in 2014 (Toyota only performed a software update), this part definitely could have been already damaged due to the software issues, which could then cause problems with the computers later on (which is what occurred). --- 1) NHTSA CAMPAIGN ID: 14V053000 - In the affected vehicles, the Intelligent Power Module (IPM) inside the inverter module (a component of the hybrid system) contains transistors that may become damaged from high operating temperatures. 2) NHTSA CAMPAIGN ID: 18V684000 - Excessive voltage in the Intelligent Power Module (IPM) within the inverter may cause the hybrid system to shut down, causing the vehicle to stall while being driven. --- General: - Computers both failed, not currently available for inspection as they are being replaced - If this computer failure happens again later (while on the road - as it has for other consumer), it's very dangerous as the car essentially shuts down on the spot - Dealer is dismissing this due to the car's age - No previous warning lights or messages

Soon after getting a recall software update for the hybrid system, the car displayed hybrid system check message and lost power. Car had to be towed. Created an extremely dangerous situation due to nature of problem while driving on the road and had to pull over right away.

I was driving the 2012 Prius on a downhill parkway at about 40 mph when the warning light check hybrid system came on. Within 10 second, the vehicle totally lost power. It automatically shifted into neutral. There was no back up fail-safe/limp home mode. Fortunately the car was gliding downhill by gravity and eventually was steered into a driveway. Then it refused to go on ready or drive mode. On this Saturday afternoon the car had to be towed home. It had to be towed again to the dealership for service the following week. It took the mechanic two days to make a diagnosis that a fuse on the main drive battery had blown. Another day was spent waiting for the part. The dealership cannot guarantee that this event will not happen again. I contacted Toyota usa. An agent named michael was courteous enough to listened to me and gave me a case number 1604142245. To anyone with common sense, this total lack of an emergency alternative propulsion system for even a cheap car is unacceptable. The dealership cannot even come up with a plausible explanation as to what may have caused the fuse to blow. Was it over heating" was there a short in some internal battery cells" this past week, I noticed that the charging part of the operation no longer can fully charge the battery to the former 11.9 mile range. It only charges up to 9.8 miles. This is a sudden loss of 2 miles of charge. I suspect that some lithium cells have been damaged after the incident. I also suspect that there may be other issues as well such as something wrong with the inverter module related to a recall on other models of Prius during my search for an answer. I need assurance from someone that this vehicle is now safe to drive. Besides the case number from my complaint to Toyota usa, aaa has record of my recent towings on 04/09/16 and on 04/12/16.

I was stopped at a red light on a hill. When the light turned green, I stepped on the gas with no response. The car slid back and I braked. The panel light affirmed that the car was supposed to be in drive. Yet there was no response at all. The car seemed to be in neutral. I put the blinkers on and the cars behind me passed. The panel lights and radio were on along with the blinkers. I turned the ignition off and then turned it on again. It worked without a problem. I called the dealer who stated he had no idea what happened and there was nothing he could check. I have driven the car to various hill tops and stopped. The problem did not repeat itself. Is this car safe to drive" is there a way to evaluate the transmission"

Fuel indicator on the dash showed 3 bars for remaining fuel. Vehicle ran out of fuel despite showing 3 bars. Oftentimes after tank is filled it only illuminates to 1 or 2 under the top bar instead of showing a full tank. There is obviously a problem that the car is not accurately reporting the fuel level.
