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.

The contact owns a 2013 Toyota Prius. The contact stated that after several days of torrential rainfall, the contact noticed there was water in the tire and 12-volt battery compartment. After having a routine oil change at an independent mechanic, while the contact was driving, the vehicle lost power steering functionality. The power steering warning light illuminated after the failure. The driver was able to restart the vehicle and pull over to the side of the road. The contact called Roadside Assistance and was informed that there was a code for the hybrid battery system that needed to be checked. The contact noticed that water might have entered through the rear passenger’s side brake light. The contact removed the water with a sump pump. The vehicle was towed to an independent mechanic who was unable to assist. The vehicle was towed to the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 119,000.

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.

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.

Status: closed (inferred from source dates) · Service Brakes, Hydraulic:power Assist
On September 19, 2019, the Office of Defects Investigation (ODI) received a defect petition from Mr. Roger Hogan requesting that the Agency investigate and recall certain Toyota Prius, Prius PHV, Camry Hybrid and Avalon Hybrid vehicles for a brake actuator valve wear condition covered under Toyota Customer Support Programs ZJB and ZKK (subject CSP?s). In support of his request, the petitioner identified 117 NHTSA complaints allegedly related to the subject CSP condition, including 60 reporting crashes. On September 30, 2019, ODI opened Defect Petition DP19-004 to evaluate the petitioner?s request for an investigation. In August 2020, the petitioner notified the Agency that he was withdrawing his petition. Because the petitioner has withdrawn the petition, we are denying the petition as moot and no further analysis of this petition is necessary.NHTSA is authorized to issue an order requiring notification and remedy of a defect if the Agency?s investigation shows a defect in the design, construction, or performance of a motor vehicle that presents an unreasonable risk to safety. 49 U.S.C. ?? 30102(a)(9), 30118. Because the petitioner has with withdrawn the petition, the petition is denied as moot. This action does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency notes that it is not required to receive a defect petition prior to opening a defect investigation and will take further action if warranted by future circumstances.
