Recently reported VEHICLE SPEED CONTROL problems on 2010 Toyota Prius

As i was driving on a road, about 25 mph, while my foot was on the accelerator pedal the car just decreased it's speed to a stop as i continually pushed my foot on the pedal.

Car worked flawlessly and we maintained it regularly. took it in to address recall of jov update pwr mgmt ecu at dealer. dealer completed recall work. 2 days later engine lite check hybrid system and the ! on and triangle on. the car continued run but now was studdering when was not before the recall work. took it back to the dealer and he said we need a new hybrid battery. we believe the software update they did created a this issue. dealer acting ignorant and saying it needs new battery because of number of miles on car. asked for diagnostic print out from when they did recall work to they new diagnosis and they would not provide. we believe the recall update created a technical problem with our hybrid battery. we also believe that dealer not being honest regarding issues with this recall update and is using it as an opportunity to reduce liability for toyota on failed recall work and to use it as an opportunity to bring in large ticket sales repair ie they quoted us a new hybrid battery for 5,500.

I have been experiencing the safety risks outlined in the following manufacturer recall number: j1v nhtsa recall number: 18v684 i have been dealing with this issue for the past 2 - 3 years and unknowingly may have been spending hundreds of dollars on repairs that may not have needed to be replaced. currently, my car is not running as i experienced a stall (11/09/2018) while exiting the freeway at a high speed with the screen reading "check hybrid system" and the dash lit up with the yellow triangle and exclamation point. i am not able to accelerate during the stall, brakes are working. this has happened to me countless times, almost always on the freeway or exiting and while traveling at a high speed. sometimes the vehicle would start back up after a few minutes of being turned off. this particular time (11/09/2018), i coasted the vehicle to a safe spot and the vehicle engine never turned on again. i towed the vehicle to my residence and then to my mechanic. i am only able to put the vehicle in neutral. the motor will not come on at all and the screen reads "check hybrid system". ...

On two occasions, june 22, 2018 and august 15, 2018 this vehicle suddenly accelerated while using cruise control and traveling at speed on generally flat, straight, 4 lane road in good weather. i have attached documents with summaries of each event and maps showing route and terrain during the events. hard braking slowed but did not stop the vehicle either time. both times, after traveling some distance while braking but continuing to accelerate without my foot on the accelerator, the vehicle made a thunking noise felt through the floor of the car and suddenly stopped accelerating. in the first incident this was after about 2 miles, the second time after about a mile. after each incident i phoned the local dealership and was told that if they could replicate the event they might be able to figure it out. i reported the events to corporate toyota and an investigation was opened. the vehicle was taken to fred anderson toyota of asheville where they spent several days with the car, interacting with toyota, who was asking them to explore and test various things related to the dual pedal fail safe, the computer, snapshots of events on the computer etc. their final ...

Brake actuator has failed. traction control, abs, brake lights illuminated on dash. more effort needed to engage brakes. this affects the regenerative braking as it no longer charges on braking as it was designed. checked toyota website for recalls since this is safety related, and there are none. which is quite disturbing. i've researched prius forums and this seems to be an ongoing problem. toyota issued a recall for the generation 2 model, however this seems to be a problem for generation 3 models as well. the problem did occur when on the highway traveling at 60 mph.

I was driving on the freeway at about 70 mph when the "check hybrid system" light came on and the car lost all power and ability to accelerate. it completely began to descend in speed and within 2 minutes came to a complete shut down. i could have easily been rear ended had i not moved to the side of the freeway as quickly as i did.

I change the brake booster twice and hace the same problem. my brake pedal loss of braking ability or slipping brakes and the warning brake, abs and traction light permanently on, and no cruise control works at all

In the past year i have had 2 occurrences of unintended acceleration. the first in february of 2016. i was exiting a parking ramp up hill and stepping on the accelerator. i was driving straight then turning to the left (90 degree turn). when i took my foot off the accelerator, the car continued to accelerate and i was unable to get it slowed/stopped for about a block even though i was applying heavy brake pressure. the car was revving against the brake pressure. no damage or injuries occurred. i took the car to the dealership where i purchased it (purchase date 8/3/13). they checked the car over and found no apparent cause for the acceleration. i took the car home, and it drove normally until 11/26/16. on that date i was driving very slowly in a flat parking lot, and the car began accelerating without my pushing the gas pedal. i was driving straight and then turning to the right (90 degree. i got the car stopped in a few feet by pressing extremely hard on the brake. my car did not hit anything. ...

I was in a parking structure going approximately 15 mph when i removed my foot from the accelerator to press the brake. before i could get my foot to the brake, the car quickly accelerated. it took at least two attempts at pushing the brake peddle before the car came to a stop. and, to be honest, the guardrail the car hit helped actually stop the vehicle. it was totally unexpected and extremely scary. in hindsight, i should have suspected that there may be a problem when i noticed that sometimes when applying the brakes to come to a stop there would be a feeling of the brakes slipping and the car lurching forward a bit. the dealership had the car towed in to get checked out, and i have been told that they will notify toyota. in the meantime i am concerned about the safety of this car!

On 05/25/2016 at about 9am, while in motion at a rate of speed approx 25 mph on a street during construction (don't know if the bumpy road had anything to do with it), the change oil soon light appeared and seconds later all the lights on the dash came on with the message to check the "check hybrid system" . i tried to stop the vehicle and it kept accelerating. i pressed on the breaks really hard and the traction control light kept flashing on and off like crazy but it barely had any impact. although the vehicle slowed, it did not come to a full stop. i ended up hitting the vehicle in front of me. thank god it was a truck and as able to stop the car from moving further or i could of ended up in the middle of an intersection. after the collision, the car would not stop although the park button was pressed and light was on. i even tried turning off the vehicle and the vehicle stayed on and in drive. i ended up in the hospital and don't know how it eventually got turned off but that was very frightening. i had ...

Brake booster pump assembly vehicle in motion when on highway when loss of breaking and steering took place. vehicle lighted icons appeared on dash along with alarm sound. (abs) (!) (brake) (ss). this unsafe condition could have been avoided if nhtsa would have forced toyota to recall this defective part in 2013 when toyota notified nhtsa of the defective braking system. or toyota mailed notice to customers as stated back in 2013, which prevention could prevent loss of life or harm. or class action. http://www-odi.nhtsa.dot.gov/acms/cs/jaxrs/download/doc/ucm442011/rcmn-13v235-0909.pdf
