MY 2013 TOYOTA PRIUS OCCASIONALLY EXPERIENCES DELAYS IN ACCELERATION AND ABNORMAL HYBRID FUNCTION. THE DEALERSHIP SAYS THEY CAN'T DO ANYTHING BECAUSE THERE ARE NO LIGHTS ON THE DASHBOARD. CORPORATE TOYOTA DOESN'T SEEM TO CARE. I ASKED IF I HAD TO GET INTO AN ACCIDENT BEFORE THIS BECAME AN ISSUE. AN EXTRA SECOND OF UNEXPECTED INABILITY TO MOVE MY CAR CAN BE VERY DANGEROUS IN MY OPINION. SO WHEN I PULL OUT OF A PARKING LOT ONTO A STREET WITH MY FOOT ON THE GAS PEDAL THERE WILL SOMETIMES AN ADDITIONAL SECOND OR SO BEFORE THE CAR STARTED TO MOVES AND AT A SLOWER THAN NORMAL PACE. I KNOW PRIUSES DON'T MOVE FAST BUT IT IS SILLY SLOW.

THIS VEHICLE ATTEMPTS TO GO 8 MPH WITH THE ACCELERATOR PEDAL NOT DEPRESSED AT ALL. IT DOES THIS ANY TIME THE CAR IS "ON", EVEN IF IT IS IN REVERSE. THE BRAKE MUST BE APPLIED TO STOP THE CAR. EVEN WHEN THE BRAKE IS PRESSED, THE COMPUTER WILL APPLY POWER TO THE WHEELS, WHICH RESULTS IN THE BRAKE HAVING TO FIGHT AGAINST THE MOTORS. SOMETIMES THE CAR CAN LURCH SLIGHTLY, AND ONCE IT HIT A CURB UNEXPECTEDLY CAUSING DAMAGE TO FRONT PLASTIC PARTS. IF YOU ARE STOPPED AT A RED LITE, YOU MUST APPLY THE BRAKE OTHERWISE IT WILL CRASH INTO THE CAR IN FRONT OF YOU ON ITS OWN. THIS BEHAVIOR IS DANGEROUS AND VERY ANNOYING. ONE MECHANIC I SPOKE TO AT THE DEALER SAID THIS IS NORMAL. IT SEEMS SENSELESS AND SHOULD NOT BE NORMAL. I ASK TOYOTA TO FIX THE MINOR DAMAGE TO MY CAR AND FIX THIS PROBLEM.

2013 PRIUS C TWO, BOUGHT BRAND NEW WITH 15 MILES ON IT 5 WEEKS AGO. A FEW TIMES WHEN DRIVING, I NOTICED THE BRAKES SEEMED WEAK, LIKE THEY WEREN'T STOPPING THE CAR VERY WELL EVEN AT LOW SPEEDS. MY DRIVING IS MOSTLY IN TOWN ON RESIDENTIAL STREETS, SO I'M RARELY GOING OVER 35 MPH. EVEN SO, I'D HAVE TO REALLY MASH THE PEDAL ALL THE WAY TO THE FLOOR TO GET THE CAR TO COME TO A COMPLETE STOP, OTHERWISE IT WOULD KEEP MOVING FORWARD. SEVERAL TIMES I ENDED UP ABOUT 5-10 FEET PAST THE LINE, STICKING THE FRONT BUMPER INTO CROSS TRAFFIC. LUCKILY NO ONE HIT ME. I CHALKED IT UP TO THE QUIRKS OF A DIFFERENT CAR THAN THE ONE I WAS USED TO, AND FIGURED IF IT KEPT HAPPENING I'D TAKE IT TO THE DEALERSHIP. ON MONDAY, MY WIFE WAS STOPPED AT A RED LIGHT. THE LIGHT TURNED GREEN AND THE CAR IN FRONT OF HER STARTED TO MOVE FORWARD. AFTER A FEW HUNDRED FEET, HE SUDDENLY SLAMMED ON HIS BRAKES. SHE SAID HER BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR, AND THE PRIUS DIDN'T SLOW DOWN AT ALL. SHE HIT HIM GOING ABOUT 25 MPH AND TOTALED THE PRIUS. SHE'S AN EXCELLENT DRIVER AND I'VE BEEN WITH HER BEFORE WHEN SHE'S HAD TO PANIC-STOP. SHE'S NEVER DRIVEN A CAR WITHOUT ABS, SO SHE IS USED TO PUSHING THE PEDAL HARD AND KEEPING HER FOOT ON IT. SHE WOULDN'T EVEN KNOW HOW TO "PUMP" THE PEDAL. SHE SWEARS THE PEDAL JUST WENT ALL THE WAY TO THE FLOOR AND THE CAR DIDN'T SLOW DOWN AT ALL. THANKFULLY, SHE'S OKAY AND NO ONE WAS INJURED. *TR

20V369000 · Hybrid Propulsion System: Inverter

Jun 24, 2020

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2013-2015 Prius and 2014-2017 Prius V vehicles not included in recall 18V-684. 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.

Consequence & remedy

Consequence: An unexpected hybrid power system shut down may increase the risk of a crash.

Remedy: Toyota will notify owners, and dealers will perform a software update for the hybrid system. If the vehicle has experienced an inverter failure with certain hybrid system faults related to this condition, the inverter assembly will be repaired or replaced, prior to software update. All repairs will be performed free of charge. This recall began July 24, 2020. Owners may contact Toyota customer service at 1-888-270-9371. Toyota's number for this recall is 20TB10 / 20TA10.

18V684000 · Hybrid Propulsion System

Oct 4, 2018

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.

Consequence & remedy

Consequence: If the hybrid system shuts down unexpectedly, it can increase the risk of a crash.

Remedy: Toyota will notify owners, and dealers will update the software for the motor/generator control electronic control unit (ECU) and the hybrid control ECU as necessary, free of charge.

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.

DP22005 · Pedestrian Alert Sounds

Opened Jan 27, 2023 · Closed Aug 7, 2023

Status: closed (inferred from source dates) · Electrical System:propulsion System

NHTSA 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 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. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

DP19004 · Brake Actuator Valve Wear

Opened Sep 30, 2019 · Closed Jan 21, 2021

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.
