What is wrong
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.
Risk
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.

Hybrid propulsion system: inverterReported November 14, 2012 · 350,662 vehicles affected
What is wrong

Defect investigations

Pedestrian alert soundsOpened January 27, 2023, closed August 7, 2023

the federal safety agency received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at 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, the federal safety agency 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 the federal safety agency 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. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by the federal safety agency regarding the subject matter of the petition.

Intermediate Steering Shaft SeparationOpened February 21, 2013, closed April 8, 2020

The Office of Defects Investigation (ODI) received a January 2013 defect petition requesting that it open an investigation on Model Year (MY) 2004-2009 Toyota Prius vehicles to address a possible manufacturing safety defect related to the steering column intermediate shaft.During the defect petition evaluation, ODI: 1.Reviewed the petition and its enclosures; 2.Reviewed the subject steering system layout; 3.Examined the Petition Vehicle?s history, including its repair history; 4.Reviewed and followed-up potentially related consumer complaints; 5.Assessed Safety Recalls 06V‑188 and 12V‑537; and, 6.Requested and examined complaint, claim, field report, service history, and warranty information from Toyota.ODI's review revealed that the petition vehicle had been recalled (Recall 06V188) to remedy a defect in the system identified in the petition with the remedy taking place prior to the failure that prompted the petition. Circumstances point to incorrect reassembly of the petitioner's vehicle by those who performed the recall remedy.ODI examined the issues raised by this petition to identify any related safety defect trend in the general subject vehicle population.That review identified a low rate of related consumer complaints (twenty-five over a eight year period from a population of over 600,000 vehicles) and no pattern that would identify either a safety defect not already covered by the two existing steering safety recalls by Toyota or a systematic problem with either recall remedy.Based on this evaluation, ODI does not believe that additional investigation will lead to a finding that a defect related to motor vehicle safety exists in the subject vehicles. Therefore, in view of the need to allocate and prioritize the federal safety agency?s limited resources to best accomplish the agency's safety mission, the petition is denied. The denial of this petition does not constitute a finding by the federal safety agency that a safety-related defect does not exist. The agency reserves the right to take further action if warranted by the circumstances.For more information, see the Federal Register notice in the public file for this action select the federal safety agency ID, enter: DP13001)The ODI reports cited above can be reviewed on-line under the following the federal safety agency ID numbers:10407520, 10418710, 10429551, 10473654, 10478195, 10478053, 10437229, 10489425, 10510722, 10639984, 10648277, 10499778, 10712626, 10723196, 10787530, 10808124, 10838803, 11071646, 11098144, 11099507, 11102659, 11160767, 11192607, 11287550, 11287606

Dashboard Warning Lights: ABS, VSC, Parking Brake Light, Triangle with Exclamation Point, Codes: C1256 & C1391, Intermittent Audible Cabin Buzzing indicating critical pressure loss on start-up for about 10 seconds...then stops, not loss so much as anti-braking quick bursts at about 5 mph of stopping v slowly and seamlessly coming to a stop. I contacted Toyota Corporate Case Management; they refused to escalate or remediate the issue due to vehicle mileage, despite being notified of the active brake pressure leak codes and the audible safety alarm.

I own 2 2009 Toyota Prius. Both cars less than 175,000 miles and both have failed ABS modules. The ABS module in this vehicle is also the power brake booster. This failure can cause braking issues such as loss of braking or sudden brake application. Only known fix is replacement of the ABS brake module which requires the Toyota Techstream service computer.

Brake actuator is broken. Toyota knew about this problem and they had a warranty for 10 years or 150k miles. Mine only has 80k miles. The repair is half of what the car is worth. I thought a Toyota with such low miles would be dependable. Toyota knew that people have died from this problem with their car. I need this car to get to work and get my kids to school. It’s older than 10 years so I am just screwed on something they knew was broken. Of course the sales person at the Toyota dealership did not tell us about it when he sold us the car

The brake actuator is failing. It’s making unusual noises when stepping on the brakes. A new additional noise started in the last month which is the pump connected to the brake actuator. The technician told me the brakes are about to fail. Toyota used to cover this issue but stopped a few years ago. It’s a $3,000.00 job at the dealer.
