My car accelerated significantly on its own while I was pulling into a parking stall in a private parking lot. It caused my vehicle to jump a curb and accelerate up a dirt divider and push over a bush that was planted in the dirt divider. Depressing my brakes did not Decelerate the car, so I pressed the Park button to eventually stop the vehicle. I-??m not sure what speed it was traveling when it accelerated, but I could smell burning rubber at the end of the incident. I-??m not sure when the smell first occurred.

Total malfunction at highway speeds. Very unsafe, the car completely shut off. This may have resulted in a highway fatality due to collision as the vehicle was in the fast lane. NTSA please do your due diligence and investigate the faulty, defective HYBRID system as I believe the faulty inverter recall is much more larger than the original recall

The breaking lights, skid lights and another light associated with breaks came out and I lost the ABS abilities, the hv battery is not charging while breaking. These lights comes out randomly. Very risky especially while breaking.

The ABS, VSC/traction control, and brake system warning lights all came on at the same time in my 2010 Toyota Prius. I almost lost control of my car's braking ability. Afterwards, the hybrid system does not perform its regenerative braking/recharging any longer. And the cruise control mode doesn't work also. The DTC from the OBD2 port is C1391 - abnormal leak in the brake fluid accumulator. I found out that this issue is widespread among Gen 3 Priuses, but Toyota has not made this officially a recall campaign, but classifies it as a "customer support bulletin." But the issue is dangerous enough that it should be a recall item. I moved homes in fall of 2018, and Toyota says it mailed out a letter about this brake issue and resulting campaign, but I never received the letter. I was totally unaware that this was a safety issue, that Toyota acknowledged it, and that this safety issue with an ongoing "recall" campaign with an expiration date. Toyota denies that this is a recall issue, and will not provide this service. I would like for NHTSA to reopen and investigate this issue, and make Toyota issue a general recall campaign to resolve this dangerous safety problem with the car.

I was driving my 2010 Toyota Prius and my car started beeping when I was driving when I tried to slow down the car was not able to stop the breaking system ABS started displaying and my car started to beep and it won-??t stop beeping. I did take my car to the dealer for a recalled inspection after my car broke down and I was no longer able to drive for my own safety. After I took the car to Downey Toyota for hybrid recall they didn-??t tell me anything but on the document they gave me it did state that the ABS was a problem. Now my car is still not able to be used because of my own safety concerns since the vehicle won-??t break when I put the brake pedal and a none stop beeping sound that won-??t stop at all.

The digital speedometer display has stopped working. I can no longer see my speed or fuel gauge. I was quoted nearly $3,000 at the dealer to repair the vehicle.

- Olean, NY, USA

The dash lights on my 2010 Prius went all dark, lost all information on my dash. No lights on dash, no fuel gauge, no speedometer, nothing. This is very dangerous to suddenly have happened and I don't see a recall from Toyota to address this problem.

Check hybrid system light ignites, slows down vehicle in middle of high speed highway. First incident November of 2020 then several incidents after. Repair shops don't assure problem according to error codes & they recommend possibilities they cannot assure will resolve the problem. Car was taken into local dealership after receiving recall notice for software and airbags prior to November 2020 when the issue began. Software update took a couple of hours. Restart/reboot temporarily allowed driving again. Most recently the system entirely shut down & the car will not start or run. Abandoned car on side of the road and got heat exhaustion from walking the rest of the way home and had vehicle towed. Error lights come on including "check hybrid system" says "shift to P position when starting" and will not allow start.

My car is accelerating while braking. Whenever I try to brake on the road while curbing or stopping at the traffic signals, the car skips/slide forward. It's getting worse on the rainy time though.

- Lincolnwood, IL, USA

Defect within the brake booster pump assembly. If this defect occurs, various warning lamps on the instrument panel made illuminate, I experience increased stopping distance, reduced hydraulic pressure within your brake system, the deactivation of brake assist, and/or the deactivation of vehicle stability control. Toyota has previously issued at least two safety recalls ' D0H and K0L ' designed to prevent similar dangerous occurrences. However, hundreds of thousands of generation III Prius vehicles (2010-2015 model years) were excluded from those safety recalls.

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". the car had over 1/4 tank of gas at the time. I currently use my vehicle for my livelihood doing independent delivery services such as instacart, doordash, postmates etc. Since there is yet to be a remedy for this situation I want to know what my options are to get back the money I've spent or compensation for this vehicle since it is not usable and unable to be fixed by the manufacturer in a timely manner. I can provide documentation in regards to repairs made as well as visits to Toyota in which they were unaware of the issue.

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 judgement was that floor mats may have interfered, though it was the first thing I checked when I regained control of the car.

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.

- South Houston, TX, USA

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.

- Palmdale, CA, USA

- Accokeek, MD, USA

The contact owned a 2010 Toyota Prius. While parking the vehicle, it unexpectedly accelerated and struck another vehicle before crashing into an apartment unit. A police report was not filed and there were no injuries. The air bags did not deploy. The vehicle was towed to an independent mechanic, but the cause of the failure could not be determined. The manufacturer was called and provided the contact with an investigator who removed a box from the vehicle, which would determine if the failure was due to driver error or a safety defect. The manufacturer determined that it was driver error. The vehicle was not repaired. The failure mileage was approximately 53,000.

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. Technicians from the dealership have not been able to find a cause and I have not been able to get past Toyota's customer service department to escalate the issue for more detailed diagnostics. I have attached the timeline of trying to get the car diagnosed and the issue escalated as well as why I don't think user error is a factor.
