BOTH DRIVER AND PASSENGER SIDE LOW BEAM HEADLIGHTS FAIL FREQUENTLY (EVERY 3-6 MONTHS) MAKING DRIVING IN THE EARLY MORNINGS AND NIGHTTIME VERY DANGEROUS, AS THEY FAIL UNEXPECTEDLY. THE MOST DANGEROUS SITUATION FOR US WITH THE HEADLIGHT FAILURE IS WHEN WE WERE DRIVING AT NIGHT IN THE MOUNTAINS AND BOTH LOW BEAMS FAILED AT THE SAME TIME. THANKFULLY THE HIGH BEAMS WERE FUNCTIONING. THE FACT THAT THERE IS A RECALL FOR 2010 AND 2011 MODELS BUT THE 2012 MODEL PRIUS IS EXCLUDED US VERY CONCERNING CONSIDERING THE ISSUE IS THE SAME ACROSS YEARS.
VSA, AVS, AND BRAKE LIGHTS ON WITH DECREASED RESISTANCE IN PETAL. BRAKES WILL RETURN TO NORMAL WITHOUT WARNING PERIODICALLY WHILE DRIVING. THIS MAKES DRIVING AND STOPPING UNSAFE AND UNPREDICTABLE.

14V053000 · Electrical System:software; Hybrid Propulsion System: Inverter
Feb 12, 2014
Toyota is recalling certain model year 2010 through 2014 Prius vehicles. In the affected vehicles, the Intelligent Power Module (IPM) inside the inverter module (a component of the hybrid system) contains transistors that may become damaged from high operating temperatures. If this occurs, various warning lamps will be illuminated on the instrument panel and the vehicle will have reduced power allowing it to only drive a short distance.
Consequence & remedy
Consequence: The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. The hybrid system could also shut down completely resulting in a vehicle stall, increasing the risk of a crash.
Remedy: Toyota will notify owners and dealers will update the software for both the motor/generator control electronic control unit (ECU) and the hybrid control ECU, free of charge. If an owner experiences a failure of the inverter before the vehicle receives updated software, the dealer will repair or replace the inverter assembly with a new one at no charge. The recall began on March 21, 2014. Owners may contact Toyota at 1-800-331-4331.

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.
Consequence & remedy
Consequence: If the front passenger seat occupant sensing system is out of calibration, the front passenger airbags may not deploy or they may deploy inappropriately for the passenger's size and position. This could increase the risk of personal injury during the event of a vehicle crash necessitating airbag deployment.
Remedy: Southeast Toyota will notify owners, and dealers will test the sensitivity of the occupant detection sensors, and recalibrate them as necessary. The recall began on March 21, 2013. Owners may contact Southeast Toyota at 1-800-301-6859.

The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition.

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.
