Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2010-2014 Toyota Prius and 2012-2014 Toyota Prius V vehicles. Excessive voltage in the Intelligent Power Module (IPM) within the inverter may cause the hybrid system to shut down, causing the vehicle to stall while being driven.
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2012-2014 Prius V vehicles manufactured August 22, 2011, to June 30, 2014. A component within the hybrid inverter assembly may overheat, causing the hybrid system to reduce output power allowing the vehicle to only drive a short distance. In some circumstances, the hybrid system may shut down causing the vehicle to stop while being driven.
Genera Corporation (Genera) is recalling certain aftermarket replacement tail lights, model 11-6468-00 (driver-side), and model 11-6467-00 (passenger-side), sold for use on 2012-2013 Toyota Prius V vehicles. The brake light and tail light circuits are switched causing the brake lights to be illuminated continuously until the brake pedal is pressed, when the brake lights will go out.
Southeast Toyota Distributors, LLC (SET) is recalling certain models interspersed through model years 2009 through 2013 as follows: model year 2009-2012 Tacoma, 4Runner, Camry, Camry Hybrid, Prius, and RAV4; model year 2009-2010 Avalon, FJ Cruiser, and Highlander Hybrid; model year 2010-2013 model year Corolla, Sienna and Tundra; model year 2009-2013 Highlander and Venza; model year 2012 Prius V; and model year 2010-2012 Sequoia. During modification by SET to include accessories such as leather seat covers, seat heaters or headrest DVD systems, these vehicles may not have had the passenger seat occupant sensing system calibration tested. Without passing the calibration test, the occupant sensing system may not operate as designed.
The contact owns a 2012 Toyota Prius. The contact stated that while driving 65 MPH and depressing the brake pedal there was a buzzing sound coming from the vehicle and the brake warning light illuminated. The contact stated that after inspecting the vehicle, the brake fluid level was very low. The vehicle was taken to a service center where it was diagnosed and DTC: C1391; was retrieved. The contact was informed that a leak in the brake accumulator had caused the brake master cylinder and hydraulic power brake accumulator to fail and needed to be replaced. The vehicle was scheduled to be repaired by the service center. The manufacturer was made aware of the failure via telephone. The contact stated that the manufacturer was aware of the failure and offered an extended warranty to cover the repair. However, the part needed to be replaced. The failure mileage was approximately 81,239.

The contact owns a 2012 Toyota Prius V. The contact stated that while driving 65 MPH, brake fluid was leaking from the vehicle. While driving over 45 MPH, the brake pedal became firm, requiring the driver to exert extra force while depressing the brake pedal; the brakes failed to respond as intended. Additionally, a burning and toxic odor was present during the failure. Multiple warning lights illuminated on the instrument cluster, including the ABS system, parking brake, brake malfunction, and electronic stability warning lights. In addition, the automotive brake system, brake pump, and pressure warning messages were displayed. The vehicle was taken to a local dealer, where it was diagnosed with a failed brake booster assembly after inspection. The dealer determined that the brake booster assembly needed to be replaced. The contact associated the failure with Customer Support Program: 20TE07. The contact was referred to the NHTSA Hotline by a lawyer, and the contact had found a class action lawsuit related to the failure. The failure mileage was approximately 187,000.

2012 Toyota Prius v with 89,662 miles. Multiple brake warning lights illuminated, and the vehicle stored diagnostic trouble code C1391, “Abnormal Leak in Accumulator.” The brake booster/accumulator pump is also cycling about every 13 seconds, even when the brake pedal is not being applied. The vehicle and components are available for inspection. My safety concern is that this involves a critical braking-system component. When the warning lights are on, regenerative braking is disabled, and braking behavior changes. I am concerned that continued deterioration could reduce braking performance or result in loss of brake assist. The issue has not yet been formally diagnosed by a Toyota dealer. I scanned the vehicle with a diagnostic scan tool, which currently shows C1391. I also contacted my independent repair shop, which recommended that Toyota diagnose the vehicle because this code is associated with the brake booster/booster pump failure previously addressed by Toyota Customer Support Program 20TE07. The vehicle has not yet been inspected by Toyota, police, insurance, or another manufacturer representative. A Toyota corporate case has been opened and escalated. There were no known brake warning lights before this incident. The problem first became apparent when multiple brake warning lights illuminated. Afterward, I noticed the brake booster pump cycling unusually often. Toyota previously identified C1391 as a qualifying code under 20TE07 for certain 2012–2014 Prius v brake booster/booster pump failures. My vehicle is outside the time-based coverage period despite relatively low mileage. I am reporting this because I am concerned this safety-related failure may continue occurring in similarly aged vehicles.

Brake actuator assembly failure on a vehicle with 99,818 miles. Whirring sound when braking followed by lighting of several brake alert lights on dash including PCS and ABS and others. The whirring noise has occured for several weeks, but the light indicators happened on 6/28/26. Toyota has an acknowledged Customer Support Program (20TE07) for this exact failure on this exact and Toyota declined to cover the repair. This vehicle is 14 years old but has well under 150k miles and Toyota will not honor claim though they clearly are aware of the safety hazard.
