My brakes has always had a weak feel and it would lose stopping power when braking on a bumpy road. Its almost like, the brakes releases when you hit a bump. There are currently two recalls for the 2010 Prius but for some reason, my VIN number is not included in it. Is there any way we can get the dealer to perform the recall? its just a software computer update, but I have a feeling they will not do it since my VIN is not included in the recall. Even though I experience the symptoms of the 2 brake recalls for the 2010 Prius. Thank you.

I was driving down the highway, I hit the gas pedal to accelerate faster through a light that had just changed from green. As soon as I did that my car lost power and a bunch of emergency lights came on, I immediately got on the shoulder. No one was behind me otherwise I would've been in a wreck. I turned the car off and on again and the emergency lights were still there. I was able to drive up to about 10 miles an hour a few blocks to a parking lot. I had the car towed to the Toyota dealership and they told me it was my inverter that over heated and needed to be replaced.

While the vehicle was in motion, the engine started shaking, the steering and brakes locked up and the engine ceased up as the car shut off. Got error code P3190 for poor engine power, and then a day later everything was normal. This is the 2nd time this has happened while driving, the first time was in a 2002 Prius.

After changed all the 12V battery and 201V battery pack brand new. All the fluid; oil, cooling water, transmission also been changed new, even clean out the exhaust CO2 deposit in the pipe, basically the engine been clean out like new. The problems now is not start or put into ready mode. Due to the inverter and icu U1 circuit board now sending the signal to the dash board. Dash board only show flashing engine light, push button show amber not green. I heard Toyota is recal the software on the inverter, this is not going to help, due to reprogram the key and the imobolizer cause the infor on the dash to shut down, the obdii cant even read or function. Now my 2010 hybrid is dead. I don't know what to do. Please help.

Recall notice eoe was performed on my 2010 Prius to correct an invertor problem. A software update was performed. According to my dealer at capistrano Toyota as well as other dealers this was just a bandaid and not a true fix. The owner of capistrano Toyota as well as other Toyota dealers have written to Toyota that the invertor needs to be replaced. The dealer H, S had many cars come back after the software fix and had to have the invertor changed. If the invertor fails while driving, the car can possibly just stop running or slow down to 15 miles. This will be very dangerous and possibly deadly.

My vehicle abruptly slowed down on Illinois highway 94 South bound at 33 exit at 2:00pm August 10. Fortunately I was in right lane, which had a slight slope that allowed me to drive my car to the service lane. Afterwards, I tried to start my car without any success. I called my car insurance agent on 2:11pm to tow my car to my mechanic. Their diagnosis was a problem with the inverter/converter. My vehicle was towed again to the Toyota dealer because this problem was in recall.

My Prius was recalled to limit current in the main power inverter as they are failing. These inverters are still failing even after the software modification. Toyota extended the warranty on the inverter as they know it could fail. I don't want to be stranded before they will address the problem!

My brakes recently stopped working as they normally do (you had to press extremely hard on the pedal to get it to stop) and several lights came on the dashboard. Prior to this the car was making a very strange noise when you start to push on the brakes. Not like a typical squeaky brake sound. I took it to Toyota and they gave me a quote for $3,700 stating that I needed a new brake cylinder assembly. I discovered a recall for 2010 Prius for the exact diagnostic code and they said my Prius was not covered by the recall. When you "reboot" the computer on the Prius, the lights and brake problem go away. This appears to be a significant problem with the 2010 Prius from what I have read on-line and Toyota is not acknowledging it. It's also a very costly repair that seems to be easily fixed when you reboot the computer on the car. What is going on" how many people are paying Toyota for this fix that appears to be a wide problem with the vehicle that should not be happening"

While driving our 2010 Toyota Prius II on the interstate we began noticing a burning smell. Then, the ABS light illuminated on the dashboard. We pulled onto an off ramp and as we slowed the vehicle down smoke began coming from under the hood. We drove very slowly down the road and the smoke became more prevalent. We turned on a side street and my husband put the vehicle in park, got out, walked to the front, and noticed that the passenger front head lamp was melted and there was a flame. We quickly got our family out of the car (2 kids in carseats in the back). We moved away from the vehicle and the flames become larger and larger. We called 911 and the hood was engulfed in flames by the time the firefighters arrived. They were able to put the fire out quickly, so it did not spread into the front cabin or rear of the vehicle. We had not had any recent work done and the vehicle was fully operational until the time of the fire. We had not been experiencing any problems prior to this incident.

The other day my brake light, traction, and ABS light came on. Took it to the mechanic and they said it's code C1391 - abnormal leak in the accumilator, electrical issue, and I must go to the dealer. I've seen others complain about this. Shouldn't this be a recall?

The vehicle was having issue with the steering locked up when turning with motion about 20+mph. The hybrid system is not as advertised the 50mpg in any way as it only gets average about 35mpg. The vehicle has 87000 miles and the old symptoms from second generation followed suit with it. The dash went totally off when weather is cold and suddenly turned back on when it gets warm. I had driven a few miles without the dash on and it was a bad experience since I cannot figure out the speed or what is going on. The steering is the major issue as we dare not to drive the car and the technicians from the dealer said nothing wrong with the vehicle but third party technicians recommend to take to Toyota for recall.U turns are the worse that locked the steering and the car almost come to a stop with beeping alarms.

I had a sudden loss of power with a popping sound. The failure nearly caused an accident because I was turning into a traffic lane. This left me stalled in that lane of traffic. The failure turned out to be the inverter over heating was caused by the cooling pump in the inverter failing, which caused the inverter to overheat. This was not covered by warranty and was a very expensive repair. I chose not to have the dealer repair it at their extreme prices. I paid the dealer to diagnose the problem. Then I had greentec in olathe ks. Repair the system at 1/2 the cost that the dealer wanted

While driving on the highway, the instrument panel cluster on our 2010 Prius went out and we were without a functioning speedometer or gas gauge for the remainder of the drive. This problem has happened to many other 2010 Prius vehicles and Toyota refuses to warranty this extremely costly repair, which causes many drivers to use their vehicles without a speedometer for extended periods of time.

Our Prius has been losing power. It has 68K miles and we are the original owners. Driving at hwy speeds we noticed we have to push hard down on the gas just to get the car to maintain highway speeds. Hills are even worse. We are also still waiting on the parts to fix our headlights. Over the years I have changed the low beam bulbs at least 6 times! when are the parts coming?

We were driving on the highway at about 70 miles per hour when the reading lights and dashboard flashed on and then off in a matter of about 5 seconds. The dash showed a triangle indicator light with an exclamation point. The dash also seemed to reset and showed the display as is the car had just been turned on. This incident happened twice within a 4 hour period. Once on the highway and once on a back road going about 40 mph. The car did not stop either time, but it is still concerning.
