The vehicle runs ok and a few minutes later the yellow triangle turns on, as well as the check engine light and the vehicle starts to lose power. After a few more minutes the red steering wheel light comes on along with the "check hybrid system" message and the rest of the lights and the vehicles loses all power and stops. It will normally turn back on but there was one occasion where it didn't and my husband had to push the car to a parking lot. I took the car in on the recall which should cover this but all they did was update the software and blame the issue on a car accident. I don't know if this is true as just purchased the vehicle but it sounds to me that they could have fixed the issue under the recall.

I had just pulled into the garage and was at a complete stop when the car surged forward and slammed into to the back of the garage, I would tip overattempted to stop the car with the brakes and they were not working so I shifted the car to reverse and it speed out of the garage up an embankment into a fence. It. was up on it's side and I was afraid that it would tip over so in an attempt to bring it down level I shifted to drive and it speed off forward it then jumped a row of bushes into the front yard and did a large circle in the front yard missing three large pine trees and hitting a small tree that ended up stopping the car and deployed the air bag.

On 4/24/14 I brought the vehicle into lynch Toyota in manchester, ct in response to a recall to fix a problem which involved losing power when attempting to accelerate. The invoice covering the repair indicated "software update for mg ECU and power management ECU as per campaign eoe". on 9/29/14 I was driving in moderately heavy traffic on I-84 in West hartford, ct when I attempted to accelerate to pass a slow moving vehicle. As I began to pass, the accelerator suddenly failed to work and the engine stopped and would not respond even though I continued to depress the accelerator, although I had no power the steering worked and I was able to glide to the shoulder across the right lane of traffic. I turned off the engine, restarted it and it has functioned normally since. I returned to lynch Toyota on 10/6/14 to have the problem addressed. They examined the vehicle but were unable to determine what was wrong and advised me there was nothing that could be done. I called Toyota customer relations at 800-331-4331 and spoke with an individual who identified himself as "[xxx]". he also advised me that since the dealer could not diagnose the problem that nothing could be done. I asked him if Toyota had received other similar complaints but he said there was no way to cross reference that information. The company's case number of my complaint is 1410062141. I am perplexed by the company's response because it has given me excellent service for the past 20 years. It seems very odd that it would not follow through further if for no other reason than the enormous liability exposure an obviously dangerous problem like this could present.

Driving 45 mph down busy 4 lane street when car just went out of gear from drive to neutral and wouldn't go into gear. Car came to a stop in heavy traffic and I was almost hit by several vehicles. Had to push to side of road. Called dealership and they sent a tow truck. They said they had never heard of this happening before but while I was sitting there waiting for a ride I went online and saw that this has happened to hundreds of people. The others affected by this defect said that heat causes a magnet to detach taking the car from drive to neutral. I am very thankful that this did not happen on the freeway or could have caused fatalities. Toyota has not recalled any vehicles or made notification to owners. This is dangerous and I'm only putting complaint in now since I didn't know how to previously. Found out 2 days after incident that the dealership has had this issue with more than 100 vehicles and that they were not being honest when they said they never saw this before. Toyota needs to get the word out before someone is killed.

The incident occurred when I attempted to accelerate onto a two-lane highway. Because of a slow and sharp U-turn which precedes the short on-ramp, I disabled the eco mode for better acceleration. When I pressed down on the gas, the car immediately emitted a loud sound, became unresponsive and was unable to gain additional speed. Even so, there was no other option but to merge onto the roadway while doing no more than 30 mph. In the meantime, the instrument panel showed a "check hybrid system" message along with several warning lights. I managed to avoid oncoming traffic (from behind) and safely pulled onto the grass. Attempts to restart the vehicle were unsuccessful with the previous message reappearing each time. The car required a tow to the nearest Toyota dealer. I received a call from them the next business day, and they explained the cause to be a defective inverter based on the diagnostic code. Fortunately, the repair will be covered under Toyota's hybrid warranty. It remains to be seen and I am hopeful this repair will fully resolve the issue.

My 2010 Toyota Prius would not start after a brief 45 minute lunch with friends. When I released the parking brake and let off the brake pedal I didn't know the car was stuck in neutral. This error was on the dashboard "malfunction when parking, park in a flat place and apply parking brake securely". when I let off the brake the car rolled back into the middle of the parking lot. I had two coworkers in the car with me; they got out and pushed the car out of the way to a flat location. Car still was disabled. I called Toyota roadside assistance and waited an hour for a tow truck; after about 45-50 minutes of waiting I was hit by a woman that wasn't paying attention; she backed into the side of my disabled car. I was pressing on the horn and she didn't hear. The impact must have freed some stuck component or something because 2 hours later when the tow truck finally came, the car worked again; no warning lights etc. Toyota looked at the car and says there is nothing wrong. I took a photo to document the warning message (plus have 2 witnesses).

I was backing my 2010 Prius out of the garage and the vehicle lunged quickly when I let off the brake. When I pressed the brake to stop, it jerked to a stop. I let off the brake again and it took off. This process of lunging and jerking repeated until I backed all the way out of the driveway and put the car into drive. It scared me. I did some research and a lot of other people have experienced similar issues. In fact, there are 27 pages of people with similar problems at the following link priuschat.com/forums/gen-III-2010-Prius-main-forum/65875-braking-in-reverse-16.html#post995838.
