2012 TOYOTA PRIUS Complaints

I bought a first generation Toyota Prius PHEV in 2012. Apparently a Customer Support Program notice was sent out two years ago which I never received. For the last year or so my Prius has made a hissing sound when I stepped on the brakes unless I push extra hard on the pedal. Didn’t think anything of it until last month several lights went off. I took it to Big O Tires and they added brake fluid and the lights went away. Next month it went off again, I took it back and they suggested taking it to a dealer. I take it to Tustin Toyota they diagnose it as a Brake Booster and Pump problem. My issue is that I never received a mailer or email like I did for previous recalls. I did transfer ownership to my wife a while back, so I don’t know if that DMV administrative change impacted the mailer. It is a safety concern as my wife drives our two kids and the brake had signs but we did not take it in to the dealer until the failure lights lit up 11 months after the expiration. Is there a chance that a Customer Support Program becomes a Recall if NHTSA receives enough complaints?

The brake booster started to make some noise every 5 seconds for about a week and one day when I was driving on the highway, all brake related warnings lights came on my dashboard. I want to brake and the brake did not hold correctly, once I touched it the car actually sped up then, I had to push hard to brake since that time the brake pedal is very hard to push and the car doesn't slow down at it should. I called Toyota many times for the extended warranty they had for this issue, but every time they apologize to me and they say it has expired. Although, I bought the car in March 2022 and the extended warranty expired on February 2022.( as they said). It is not fair that they have an extended warranty for brake booster for 10 years and when I get this same issue outside 10 years by one month, I'm not qualified. This is a safety issue and they are at fault. It should be for life to prevent disaster from happening and save innocent lives. Thank you. I have included some photos

I was driving my 2012 Prius on the highway at around 55 MPH. The Hybrid System Warning came on and the car lost all power and immediately began to coast. I was fortunate not to have been in or caused an accident but cars behind me had to swerve to avoid hitting me. I was able to coast to a middle median lane. After waiting 15-20 minutes, the car never regained power. We were finally able to push it off the road and into a parking lot. It never regained power.

Seven days ago, the hazard lights on our 2012 Prius suddenly would not turn off. By the time we got home, the brake, ABS, and the traction warning lights all came on. Two hours later, the hazard lights stopped blinking but the other lights were still on. We brought the car into the Toyota dealer for service the next morning (8/1/2022) to have the issue checked, notified the service writer of the hazard light being the initial issue. Mechanic cleared the codes and the lights all were off and stayed off after what he said was 2 test drives. We asked him if the mechanic had tested the hazards, to be sure they didn't stay on. He said the mechanic had left and we agreed to leave the car overnight so he could check that again. The service writer gave us a list of other repairs/maintenance we should have done but none of them was the brake booster acuator. We declined the other service and went home. Car drove fine. Yesterday morning, we woke up to see the hazard lights flashing, even though we hadn't egnaged them since the previous Sunday. Our neighbor noted he noticed them flashing at 2 am. We brought the car back to the dealer and when my husband spoke directly with the manager, he (manager) said that they weren't aware of the hazards flashing. That is a lie. I told the service writer when it was brought in and then we discussed it again that afternoon. Manager calls us late yesterday to say that we need to replace the brake booster acuator at the tune of $3400+. The manager told us this morning that Toyota had a recall on it but they weren't notifying people unless the issue occurred. He said there was recall coverage, which Toyota extended, but it expired 7/24/2022. We never received any mail or email notification of a recall and have only had our car serviced at this dealer. Why did they not warn people? We are outraged and livid. How is this kind of greedy chicanery allowed?

ABS system has malfunctioned- brakes lose pressure constantly (makes a barking noise when pressing on them or holding them down), and brakes feel very squishy. Car constantly makes whirring noise of actuator pump trying to function. Mechanic said on inspection that it was the abs actuator and potentially the master cylinder as well. Vehicle is unsafe to drive

Running errands and when I got back to my Toyota prius v many lights were illuminated including my brakes abs tire pressure traction lights were all on. Tool my car to dealer for them to gladly request $5,000 to repair this. Dealership told me "the repairs are going to be a new master cylinder + new brake booster pump + fluids as needed for repairs" . This is a known issue for 2012 to I believe 2014 prius model V. This is a huge safety issue and a manufacture error This should be recalled and covered by Toyota as shouldn't be any fault of my own. On today's world 5k is a crazy amount of money to fix a known issue thay could arise again. Toyota needs to do better to protect their customers. Shame on them.

2012 priusV has intermittent vsc and traction control when cornering left or right at slow speeds, as less than about 20mph, 5-20. This is happening on dry road conditions at unpredictable times. The vehicle may deceleration and have a lungeing behavior with traction and or bracking interrupted momentarily. On accelerating from stop sign turning left or right the vehicle may pause accelerating briefly and pull with the abs brake auto/ intermittently applied.The traction control light may or may not illuminate at the short time interval of these events, but traction control light does not stay illuminated after the event is over. No error code is read from the vehicle with error code reader. These events are very startling and cause sometimes cause the vehicle to speed up or slow down abruptly. These events are happening at low speeds, however with the car surging forward or abruptly slowing on corning and lane changes there is potential issues of keeping the vehicle under proper control at these times. I believe Toyota should correct this problem so that it never occurs. Toyota to Find a solution an implement a recall to update vehicle.

The headlights are not functioning properly as a result of severe discoloration of the lens material. This creates unsafe driving conditions at night since the road is not properly illuminated, especially in areas with inadequate street lighting.

I have the same issue as every other Toyota Prius owner. My car has 177,000 miles and Toyota quoted me $3200.00 to replace ABS system that causes Brake Failure and risk of Crashing. All the ABS lights come on and the car almost loses all braking power.

TCS, ABS, Check Engine, and Warning lights all came on at once. Brake pressure immediately decreased. After the following diagnosis, Toyota said the brakes will continue to worsen and fail completely. Error codes C1249 and C1391 were presented. Toyota dealership diagnosed a leak within the brake pump actuator and said these parts needed replaced: 04009-79147 Brake cylinder kit 04006-22212 Brake pump assembly
