2012 TOYOTA PRIUS Complaints

I have a 2012 Prius V with just under 65k miles. This morning I woke up to go to work, drove about 5 minutes down the road when suddenly the ABS, PCS, brake and traction control lights illuminated. My brakes felt much more stiff, the car took longer to brake, and I had to depress the brake pedal down much further than normal to get any braking response at all. I quickly scheduled an appointment to bring my vehicle to my local Toyota dealership for inspection. I was told by the service department that it will cost me $4.5K to replace the ABS actuator pump (47070-12020) and brake booster & master cylinder (47050-47110) because the system malfunctioned/failed. I was in shock! I quickly ask if Toyota had an open recall for the ABS brake malfunction/failure issue and was told no. That answer did not sit well with me because this is a serious problem. Plus, this should not happen to a vehicle with under 65K miles. I've owned several Toyota vehicles in the past and I’ve never had anything like this happen to me. Today, I searched “2012 Prius ABS Brake Issue” online, and found multiple stories similar to mine on blogs, posting, etc... about the Toyota Prius ABS brake problem. I even heard that Toyota had a program in place to address this issue but it expired in 2019. Vehicle owners had to fight to bring the issue to Toyota's attention in order to get their vehicle repaired before the end of the program. Can you tell me why the NHTSA haven't forced Toyota to issue a mandatory recall to address this serious and know safety issue? Toyota knows about this issue and should be held accountable to fix the problem. I don’t want anyone to lose their life due to this known issue. Please help force Toyota to keep the road safe for all of us. Thanks, [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

The front and driver side air bags did not deploy (although the passenger side air bag did deploy). Initial impact came from behind, toward the passenger side, causing the vehicle to turn fully sideways, where the vehicle was then t-boned on the driver's side. The lack of driver side air bag deployment resulted in a lot of glass making it into the left side of the driver's head.

I mention this to toyota in January and they said the light sometime just come on .I don,t know what the mileage should have anything to do about a recall

I took my vehicle in to the Toyota dealership last month because of a brake related noise that was concerning and a loss of brake sensitivity. The diagnostic showed that the brake booster was showing signs that is would fail soon. I was informed that there was a warranty program (ZJB) for it but the warranty required that a specific error code must be present (C1391), regardless of the obvious symptoms. They were unwilling to honor the no cost replacement even though everything but the error code was present. Fast forward to just under a month after the warranty period expired (16 APR 2022 was the expiration date, today is 13 MAY 2022) and the vehicles brakes nearly fail and the error code, which was required for the warranty replacement is now present. Toyota is unwilling to assist me in the slightest with the cost regardless of the inspection prior to expiration of the warranty showing that is was approaching failure and the error code showing shortly after expiration of the warranty. I never received a notice that there was even a warranty for the part in the first place, I was only informed when it took it in the first time, before the warranty expired.

The vehicle was traveling on the interstate at cruising speeds around 70 MPH when the braking system suddenly lost nearly all function. The dashboard began displaying multiple brake system warnings. There was no warning about potential failure. It was sudden and started when the brake pedal was not engaged. Some braking power remained, but it required full activation of the pedal. The vehicle was then driven very slowly to the next exit and later towed to the Toyota dealership for repair and inspection. The dealer has confirmed that this is the same error described in Toyota's Customer Support Program ZJB. Two adult passengers and one infant inside the vehicle and all other vehicles in the vicinity were at risk of suffering a high-speed crash.

ABS dashboard light and loss of brake efficiency originally occurred on 2/23/22 and it has stayed lit every time vehicle is driven since then - and brake efficiency is affected since then. The ability to brake on demand is of paramount safety concern to the driver and passengers of our vehicle and also to those around our vehicle. The vehicle is available for inspection upon request. The vehicle was confirmed to have the same issue called out in the Toyota Customer Support Program (CSP) (https://static.nhtsa.gov/odi/tsbs/2020/MC-10181800-9999.pdf): replace Brake Booster and Brake Booster Pump Assemblies. The vehicle had some of the same DTC codes mentioned in the CSP and a few more. I have a photo from 2/24/22 proving ABS lights came on. This falls within the CSP by date (10 year from being put in service for this vehicle would be on 3/2/22) and just 3k over by miles. We are a loyal Toyota household - this is one of 3 Toyota vehicles we have owned (two Prius and Sienna) - and are in the market for an EV, and are excited about Toyota's new entry BZ4X in EV market. Toyota looking other way is an insult to brand loyalty and also violates the "spirit" of such CSPs (as opposed to Recalls, where I would have gotten this repair done timely before this failure happened). Also, equivalent CSP for a different Prius model (Prius C) (announced in May 2021 - 8 months after Prius V program was announced in Sep 2020) allows for the same Brake Booster and Brake Booster Pump Assembly issue to be covered up to Nov 30, 2022 and unlimited miles. How does it make sense that a 2012 Prius C owner experiencing the exact same problem on the exact same components on the exact same date would be covered while a 2012 Prius V owner would be denied the benefit? I would like NHTSA to work with Toyota to extend the CSP program officially to cover more vehicle owners like us and not live them stranded. That is not we expect from a company that prides in quality workmanship, customer-centricity.

The contact owns a 2012 Toyota Prius. The contact stated that after starting the vehicle, the vehicle lost brakes and power steering functionality. The traction control, ABS, and braking system warning lights were illuminated. The vehicle was towed to the local dealer and was diagnosed with brake booster failure. The vehicle remained at the dealer and was not yet repaired. The manufacturer was notified of the failure. The contact related the failure to NHTSA Campaign Number: 13V235000 (Service Brakes). The approximate failure mileage was 80,000.

Faulty brake and ECU assembly failure. A safety issue when driving. Was told by mechanic NOT to drive car as it could suddenly stop. Took car in 9/11/15 for software update for motor generator ECU and power management ECU as recall letter suggested. This is apparently common and needs to be corrected without cost to driver.

The front windshield wiper no longer performs on high but does perform on the lower settings. We experienced very heavy rain yesterday for the first time in a while and needed the high setting to adequately visualize the road and vehicles. It once switched to high the wipers were inoperable and had to be reduced in speed to even function. This is a significant safety concern as it drastically compromises your visibility in heavy rain conditions, such as those we experienced. Yes it is available for inspection upon request.

Brakes started making leaking sound when stopped at lights. Went to get diagnosed and was told I needed to have brake booster (toyota PN 47050-47180) and related pump assembly (Toyota PN 47070-47060) replaced. The specific cause note given by the technician: "FOUND BRAKE PUMP AND BOOSTER ASSEMBLY TO BE LEAKING INTERNALLY CAUSING PUMP TO ACUATE MORE THAN NORMAL WHICH WILL CAUSE THESE NOISES" Found out researching online that this is a common issue with the brake booster/master cylinder assembly affecting multiple models and model years of Toyota vehicles and a pending class-action lawsuit in Texas for it. Was told there was no recall but there was an extended service option. I was not made aware of this extended service option which they indicate in the program notes would be mailed to vehicle owners, and was told when the issue was diagnosed that my vehicle does not qualify for it.
