While driving on the highway, ABS, "Brake"/E-Brake, Traction Control Lights lit up all at the same time out of the blue. No prior engine lights/codes before this incident. During that trip, brakes felt more difficult to press, loss all brake regeneration for the hybrid battery but was still about to brake for that entire 100 miles trip. As of now, the car is still able to brake but it looks like it's just primarily using the mechanical brakes all the time now. It still has that different brake feel compared to when before all those engine lights went on. Regenerative braking is no longer working. Brought the car to the shop at was given the error codes C1391 and C2315.

I was driving and suddenly the car started beeping and the brake, e-brake, abs, and traction control lights came on. As soon as I found an opportunity I tried to brake but the car would not stop and the brake pedal became really hard. I had swerve to avoid hitting cars in front of me. It was the scariest moment of my life. I shifted the car from D to B to use the engine braking. I finally was able to slow down enough to turn right on a side Street and pushed on the brake pedal with all my strength and it finally came to a stop. I was lucky I didn't have a collision or strike a pedestrian, that I also drive defensively and leave enough space in front of me, and that I was on a surface street and not on a freeway which I frequently use because if I was I would have surely crashed. This is NOT right. Brakes should NOT suddenly fail! Under any circumstances. It was confirmed by a mechanic that it's the BRAKE BOOSTER AND BRAKE BOOSTER PUMP ASSEMBLIES had failed and had the following codes C1252, C1253, and C1256 were found. The same issue and codes reported in tsb pol18-03.

Took vehicle for state inspection on 2/13/2024, failed inspection because of brake warning lights. Slip indicator, Electronically controlled brake warning light, Brake warning light, Anti-lock brake system, and Low tire pressure lights are all on. I have looked into it, and it seems the brake actuator/booster used to be under warranty, however since this is a 2013 in 2024 with almost 210k miles on it, it no longer qualifies for the original recall.

ABS Brake Warning Light On-stays on-this just happened within last 2 weeks. Not sure on safety measures but unsure if I keep driving it the brakes will just give out. The problem has been confirmed and seen by Tire Max but no diagnostic tests were ran. The just saw the light was on. No one has inspected the vehicle component by the manufacturer, police, or insurance company. No warning lamps prior to the problem but the ABC Warning light stays on while cranked and it first appeared about 2 weeks ago. I do want to add that a similiar recall or warranty had been put out by Toyota on Sept 4th 2020-(T-SB-0089-20) for 2012-2014 Prius V & C stating: "Some 2012-2014 model year Prius V hybrid vehicles may exhibit a condition where the brake, ABS, and/or TRAC warning lights are on and/or a Check VSC message displays. Diagnostic Trouble Codes (DTCS) C1391, C1252, C1256, C1253 may be stored. This condition may be caused by a small internal brake fluid leak inside the brake booster assembly with master cylinder. The warranty was for Prius V or C but my Prius(no V or C) has been affected with the same issue but Toyota will not honor this warranty or recall due to the problem not showing as specific to my vin#. So I am reporting this problem so it can be submitted that there is a similar problem with my Prius as well as the Prius V or C so others could submit their problem as well. I cannot afford to fix this myself. I need Toyota to back up their cars.

Brake system failure. Traction control light, brake light, abs light, and brake system warning light all lit up on dash. The regenerative braking is no longer working or charging battery. Obvious loss of stopping power. Does not feel safe to drive at all. Toyota wants $3,000-$4,000 for the repair. Toyota should be held liable for these failures causing crashes and potential fatalities. This should already be a recall.

Check hybrid system. Stop the vehicle in a safe place. About 90,000 miles 2013 Prius bought brand new and regular all dealer maintenance completed. Lost power on the road and very slow pickup. Not drivable and very unsafe car. Thanks.

We have been experiencing on multiple occasions car while driving will slow down, hybrid safety warning light on dashboard will turn on and tell us we have to go to a safe area and turn off car. The car will automatically shut down like a golf cart feeling. We have had near incidents were we have almost crashed. The car now will not go past 35 miles. We brought the car to a Toyota Dealership because we noticed their was a software update recall. When we left the car repeated the warning again about 5 minutes leaving the dealership. The dealership has not helped us and refuses to fix car. We mentioned to them that there have been many complaints regarding the same issue.

I was loving my Prius until yesterday June 9, 2021 when I took it to Toyota of Riverhead, NY to have my Hazard lights checked because they would not shut off. I was told that the technician found ABS actuator shorting out causing the hazards to not go off. The replacement would be $2664. I had the fuse removed because it was causing my battery to die with the hazard lights being on. I was also advised by Tonianne Rempel (service advisor) that Toyota was familiar with this problem with 2013 Prius. I have a problem with Toyota knowing that there is a problem with the hazards for this is potentially dangerous for it makes your battery die and leaving the owner stranded. This should have been a recall. I had removed the fuse so now I have no hazards or directionals leaving me to use hand signals. Which is extremely dangerous for other drivers do not look for driver using hand signals. This embarrassing for Toyota drivers seeing that somebody driving a Toyota is using hand signals because the directionals don-??t function. Toyota should have done a recall knowing that this hazardous situation exists. I am asking Toyota to pay for this repair. I do not have $2664 to repair this hazardous situation that should have been addressed by Toyota and leaving me in a very dangerous situation without hazards or directionals.

I keep getting a P0136 bank 1 sensor 2 error code. Took it to several mechanics and they switched the 02 censor (downstream). Also shows that bank 1 sensor 2 has 0% voltage. Unplugged the downstream 02 sensor and got a reading but no reading when plugged in. Checked wiring harness to ECM and everything was fine. Both mechanics have determined that the issue is with the ECM. My vehicle has roughly about 70K miles on it. My car will not pass smog until this is fixed. Mechanic is recommending reflashing ECM or replacing it. P0136 comes up as pending and will stay permanent on the second drive cycle. Check engine light stays on.

The car gave a triangle of death and looked it up if any recalls had been made that could possible cause this issue and there was 1 that called for an update to the system which I had done and they had told me if it didn't take they would have to do the invertor which was apart of the recall. A week after the system update the same issue arose and they refused to replace the invertor which drained the hybrid battery and ruined it also. This effects the driving ability and causes the car to shut down the lights to not work. It can stale at any given time and will not have power to continue

I am having problems with rodents getting into my car. I fear that they are chewing on electrical wiring and there is possible distraction to the driver. When I was driving (car was moving) a mouse crawled up on my shoulder. These problems appear to be a problem with this model Toyota and could cause a distraction to the driver and a driving issue with wiring.

We have had multiple low beam bulb failures. Usually it starts with 1 the burns out the other within a week or two. In the last year we have replaced both bulbs 3 times. The last time was February 24th last night on March 11th we received a warning ticket for a headlight out. I went to replace the bulb again and it was good, after removing it I reinstalled and it worked. Shut the car off and came back out and it wouldn't come on again without disconnecting the harness and plugging it back in. There is noticeable discoloration on both headlight plugs.

My car has stopped running with all warning lights and hybrid system failure warning three times now. First time I was driving when lights came on but got to parking lot where it died. I was able to restart car after a couple of hours, still all warning lights and hybrid warning showing but was able to get it to dealership. Second time I was driving on small road and was able to get car to side of road. Again it started after a couple hours with all warnings lit and I was able to drive to dealership were it also died again but they started it later by resetting codes. Third time it stopped in driveway and I was unable to start it. Had it towed to dealership. First time. 12V battery was replaced and software update performed. Second two times ira Toyota dealership has sent me back out on the road to wait and see if it happens again.

While driving our 2013 Prius on a 5 five-lane highway 2-10-20, our Prius goes into limp home mode all the sudden and slows the car down significantly while driving at highway speed. This occurred at the same time as I was passing a car to exit the highway, also with another car close at the rear clearly intending to get ahead of me after I had passed the other car. I unexpectedly realized that I had no acceleration and that the all the dash lights had come on. I was very fortunately to be able to maneuver across the driving lanes to the highway exit without being hit as my speed go down. The situation was extremely hazardous. Took the car to the Toyota dealership the next day on 2-11-20 and the tech discovered the car went into the limp home mode because of a catastrophe inverter failure. We did receive the updated software from the recall in 2014, yet the inverter still failed. The inverter was repaired by the Toyota dealership 100% under warranty.
