Defect. 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.

Defect. Toyota is recalling certain model year 2004-2009 Prius vehicles manufactured August 6, 2003, through March 30, 2009 and FCHV-adv vehicles manufactured December 12, 2008, through September 13, 2011. During manufacturing, a scratch may have occurred inside of the electrically driven water pump at the coil wire. The coil wire may corrode at the scratched portion.
Risk. The corroded coil wire may break and the water pump could stop. The corroded coil wire could cause a short circuit between coil wires and a possible open fuse, creating a stall-like condition of the hybrid system while the vehicle is being driven. This may increase the risk of a vehicle crash.
Remedy. Toyota will notify its owners, and dealers will replace the electric water pump, free of charge. The recall began on January 17, 2013. Owners may contact their Toyota dealer or the Toyota Customer Experience Center at 1-800-331-4331.

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

Fuel/Propulsion System
Filed Jul 18, 2022NC
Our 2009 Toyota Prius is known as a Gen 2 Prius (model years 2004 -2009). All Gen 2 Priuses has a bladder inside their fuel tank. Over time, these bladders are known to deteriorate. In our case, the fuel tank capacity is shrinking and fuel can be difficult to add to the tank (pumps click off repeatedly and occasionally, fuel splashes back out of the tank). Additionally, the fuel gauge reports unreliable statuses and drops or adds multiple "bars" at a time yet fuel, when added, and tank status as reported by the gauge, are inconsistent with one another. Thus, we, the drivers, don't know how much fuel is in the tank and may consider carrying a full gas can to avoid being stranded along the roadside. We believe Toyota knew about this Gen 2 defect at the time we purchased our 2009 Prius, which was in March, 2009. In fact, the new Gen 3 Priuses, starting with the 2010 model year, had already had their fuel systems redesigned and factories were probably being retooled when we purchased our vehicle. Thus, they knowing sold us a vehicle with a known product defect. Now, with the bladder deteriorating, the local Toyota dealership wants to replace our fuel tank/system at a cost of almost $2,000. The replacement tank will be of an identical design as the one they sold me in 2009. So they want me to pay an additional two grand for a tank that has been known to be defective for the past 13 years. This is unbelievable!

Over the years the rubber handle which needs to be pressed in in order to open the trunk has disintegrated. Now it’s at the point where the assembly under the rubber handle is exposed. It is getting harder and harder to open. I need to be able to get into the truck to get to my spare tire and road hazard equipment. I can’t get a picture s8nce it’s too close to the body and covered by the overhanging trunk lid. It’s about $500 to fix. But I rarely use that handle, so it certainly was never abused.

I was exiting the highway and had no brakes, the pedal felt hard but wouldn’t slow the vehicle at all. In a panic I attempted to pump the brakes and by the grace of God was able to finally stop before plunging into something. The lights came on on the dash with a triangle and exclamation mark and a horrible continuous beeping noise started. I looked up the problem and found out this is a known problem with the Prius and there was even an extended warranty that ended in 2017 for the cause of the problem which is the brake actuator. Toyota quotes the repair at 2500-3000. So if it goes out after 2017 the cost is on you. This repair is necessary due to the huge safety concern!! Lives at risk because Toyota refuses to accept responsibility.

The brake actuator is failing in my 2009 Prius Touring. This is confirmed by the dealership. Brakes work intermittently when reversing and are slowly becoming non-responsive during normal driving. This creates an unsafe situation for me and my son as drivers, as well as others on the road. The brake light and ABS light is on in the car. Toyota needs to cover this repair regardless of the year of the vehicle. Service code given by the dealership is C1391.

I went to park in a parallel space when all of a sudden my ABS, (!), VSC light come on with the loss of brake power and a loud beeping noise. With this sudden loss of brakes in the middle of driving, I could have harmed myself and others in any cars around me because I also lost steering capability. This is a problem that there was an extended warranty for, but there should be a recall. My car is a 2009 and was only covered before the pandemic and now it is 2021 and I have no recourse, but to try and fork over $3500.00 for which I don't have. I am a second owner and this is a very common problem amongst Prius owners. I didn't have any other symptoms that I could point out prior to this situation. I have had my hybrid battery, engine, ecu and most recently a stolen catalytic converter replaced. This ABS actuator problem needs to be addressed for another 5 years with a free repair. I would hate to have hit some other car and had my car smash into a wall, another car, pedestrian, pole or any other object based on it's ability not to stop.

My 2017 Prius is having headlight failure. I was told by my neighbor that my headlight was out. I bought a new one and went to replace it but they were both working. Thought it was a defective bulb so waited to replace it. I check both headlights when I come to a stop behind a car so I can check the reflection of the headlights. Sometimes they are both on sometimes only one is on, Occasionally both are OUT. What I have noticed is when I turn on the car, immediately the headlights are bright,(not high beam) and immediately go dim. This acts like a bad contact or high resistance somewhere in the circuit. The headlights going on and off seems to be a circuit breaker of some kind. Fortunately I don't drive much at night, however I am having to drive more at night and the possibly of the headlights both failing is TERRIFYING. I started to research the problem and it seams I am not the only person having the problem. The internet is full of other people having the same problem. It seems that nothing is being done about it. I am hoping that Toyota is NOT deciding to just let the people kill themselves because it will be nearly impossible to prove that the headlights were out at the time of the accident so they will not have to pay a lawsuit and not have to fix a recall problems. I am 74 years old and been an auto mechanic all my life so I know about automobiles and wiring. I doubt that anything will be done, and wonder how many people have been killed because no one will dig deep en

My 2009 Toyota Prius abruptly lost power while driving. The electrical system turned off and the vehicle stalled while going 50 mph on a 2-lane parkway. While I was able to put my hazard lights on and steer the vehicle, I had no other control and was at a high risk of a crash. There's no emergency lane and few areas wide enough to pull over on the parkway. I was forced to coast the vehicle until I could pull off the parkway onto a patch of grass off the busy road. There were no warnings, messages, or other symptoms of the problems prior to failure. I had plenty of gasoline in the tank, so it wasn't due to a lack of fuel. The car would not start after pulling over and I had to get towed. After researching the issue, it sounds very similar to the safety recall involving certain 2013-2015 Model Year Prius and 2014 – 2017 Model Year Prius v in the United States, the press release for which was published on June 24 2020: https://tinyurl.com/4mrnz9nr Furthermore, the Los Angeles Times wrote an article on April 23 2018 about a similar issue, referring to a recall in 2014 which was intended to fix overheating problems in the 2010-204 Prius inverter. Those recall documents suggest that Toyota has been tracking this issue with the inverter since 2011. https://tinyurl.com/afwvt2sc A sudden power loss is generally considered a serious safety defect.

IN DECEMBER OF 2018, I PULLED MY CAR UP TO A REDBOX STATION TO RETURN A MOVIE. I PUSHED THE PARK BUTTON ON MY 2009 TOYOTA PRIUS AND GOT OUT OF MY CAR TO PUT THE MOVIE INTO THE SLOT. THE CAR APPARENTLY WAS NOT IN PARK AND CONTINUED TO MOVE FORWARD (I TRIED TO CATCH IT, BUT WAS UNSUCCESSFUL, AND HURT MYSELF IN DOING SO) UNTIL IT SLAMMED INTO A PARKED CAR IN THE SAME PARKING LOT. MY INSURANCE LISTED IT AS AN AT-FAULT ACCIDENT AND FIXED MY CAR AND THE ONE THAT MY VEHICLE HAD HIT. (I TOLD THE ADJUSTER I KNEW THAT I HAD PUT THE CAR IN PARK) I ALSO HAD A 700.00 DEDUCTIBLE TO PAY FOR FIXING MY DAMAGED CAR. AS TIME WENT BY, THIS STARTED HAPPENING MORE AND MORE FREQUENTLY. I WOULD PUSH THE BUTTON FOR MY CAR TO GO INTO PARK MODE AND IT WOULD NOT GO INTO PARK. I WOULD HAVE TO PUT THE CAR INTO ANOTHER GEAR AND THEN IT WOULD GO INTO PARK. OTHER WEIRD THINGS WITH THE CAR WERE HAPPENING AS WELL. SOMETIMES THE CAR WOULD NOT TURN OFF AND MORE AND MORE WHEN I WOULD START THE CAR, THE DASHBOARD WOULD BE COMPLETELY BLACK. I MENTIONED TO MY MECHANIC THAT THIS WAS HAPPENING, HOWEVER, I COULD NOT MAKE IT HAPPEN WHENEVER I TOOK IT TO HIM. I DID MANAGE TO GET IT ON VIDEO THOUGH THAT IT WAS HAPPENING. I JUST RECENTLY LEARNED FROM MY MECHANIC THAT THIS HAS BEEN A SAFETY ISSUE WITH THIS CAR AND THAT IT'S A BAD COMBINATION METER. HE ALSO INFORMED ME THAT TOYOTA ONLY ALLOWED FOR 9 YEARS FROM THE DATE THE CAR WAS MANUFACTURED FOR THIS PROBLEM TO BE FIXED. HOW COME I DID NOT RECEIVE ANY NOTIFICATION THAT THI

I PURCHASED A 2009 TOYOTA PRIUS WITH 109,000 MILES, I HAVE ONLY BEEN DRIVING IT TWO MONTHS AND THE BRAKE ACTUATOR IS GOING BAD! TOYOTA HAD A RECALL AND PROVIDED A FREE OF CHARGE FIX BUT ONLY UP UNTIL 2017 I BELIEVE. THEY SHOULD PAY FOR ANY FAULTY ACTUATORS UNDER 150,000 MILES ON THE VEHICLE BECAUSE THAT IS THE MILEAGE THEY WARRANTY THEIR HYBRID BATTERIES FOR. DRIVING MY VEHICLE I COULD STOP AND ALMOST GOT INTO AN ACCIDENT BECAUSE OF THIS FAILING SYSTEM! I COULD HAVE BEEN KILLED. I WAS DRIVING IN THE CITY AND LOST ALL POWER IN MY BRAKES.

MY 2009 PRIUS WITH 96425 MILES AS OF 10/29/20 HAS THE COMMON PROBLEM KNOWN AS FAILURE OF THE BRAKE ACTUATOR ASSEMBLY. I HAVE THE BRAKE, ABS, AND VSC WARNING LIGHTS INDICATING FAILURE OF THE BRAKE ACTUATOR ASSEMBLY. MY MILEAGE IS REDUCED BY 25%, AND THE BRAKE ROTORS ARE VERY HOT AFTER DRIVING THE VEHICLE. TOYOTA ISSUED A ZG1 WARRANTY ENHANCEMENT PROGRAM TO COVER THE COST FOR REPLACEMENT OF FAULTY BRAKE ACTUATOR ASSEMBLIES, BUT MY VEHICLE IS BEYOND THE LIMITS OF THE ZG1 PROGRAM. SINCE THIS IS A KNOWN PROBLEM, IT IS MY OPINION THAT TOYOTA IS RESPONSIBLE TO CORRECT THE SITUATION. TOYOTA WILL NOT ASSIST ME IN RESOLVING THIS DANGEROUS SITUATION, AND THIS IS WHY I AM BRINGING THIS MATTER TO YOUR ATTENTION. IT IS AN EXPENSIVE REPAIR, THIS IS A KNOWN PROBLEM WITH THE BRAKE ACTUATOR ASSEMBLY, AND POTENTIALLY COULD RESULT IN SERIOUS (EVEN FATAL) SITUATIONS.

WE HAVE A 2009 PRIUS WHICH STALLED ON THE FREEWAY AS MY HUSBAND WAS DRIVING IT YESTERDAY (10/16/2020). LUCKILY, EVEN THOUGH IT WAS A BUSY AUSTIN FREEWAY, MY HUSBAND WAS ABLE TO MANEUVER IT TO THE SHOULDER AND CALL AAA TO TOW THE CAR TO THE SERVICE STATION. ON INSPECTION, WE WERE TOLD THAT THE REASON FOR THE STALL WAS THE FAILURE OF THE INVERTER DRIVE PUMP ALONG WITH THE 12V BATTERY ON BOARD. THIS CAR WAS PART OF THE RECALL FOR THE INVERTER DRIVE PUMP AND THAT WAS REPLACED BY AN AUTHORIZED TOYOTA SERVICE CENTER IN 2013 FOR A SIMILAR ISSUE. ON THE OCT 16TH, 2020, THERE WERE NO WARNING LIGHTS - NO ENGINE CHECK LIGHT AND NOT EVEN THE 'MAINTENANCE REQUIRED' LIGHT - THE CAR TURNED ON JUST FINE, MY HUSBAND WAS ABLE TO DRIVE IT 5 MILES TO THE FREEWAY, GET ON THE FREEWAY AT 60 MPH AND DRIVE A FEW MILES ON IT BEFORE LOSING ALL POWER IN THE CAR. THE SERVICE TECH INFORMS US THAT THE INVERTER PUMP CAN BREAK DOWN DUE TO JUST REGULAR DRIVING - BUT THERE WAS ZERO INDICATION THAT THIS UNIT, WHICH APPARENTLY IS CRUCIAL TO THE CAR WHILE BEING DRIVEN, WAS IN ANY DANGER OF IMMINENT FAILURE. I DO NOT KNOW IF THIS PART IS EXAMINED OR SERVICED AS PART OF REGULAR MAINTENANCE, BUT NO WARNINGS WERE RAISED WHEN THIS CAR WAS LAST SERVICED, AT AN AUTHORIZED TOYOTA SERVICE STATION IN DEC OF 2019.

THE BACK LATCH OF MY GRANDDAUGHTERS 09 TOYOTA PRIUS HAS DEGRADED ("MELTED" ALMOST). IT NO LONGER FUNCTIONS PROPERLY, AND WE ARE UNABLE TO OPEN THE BACK HATCH DOOR EASILY. SOMETIMES IT REQUIRES CONSIDERABLE EFFORT AND PERSEVERANCE TO GET IT OPEN. I AM CONCERNED THAT IN THE CASE OF AN EMERGENCY, SHE WILL NOT BE ABLE TO GET THE DOOR OPEN. THIS IS A MAJOR CAUSE FOR CONCERN AND IT IS A SERIOUS SAFETY HAZARD. IT IS NECESSARY TO GET TO THE SPARE TIRE, MAYBE EVEN GET OUT OF THE TRUNK IN CASE OF A FIRE OR OTHER REASON. IT IS A BLACK, GOOEY MESS. SHE FIRST NOTICED IT A COUPLE OF YEARS AGO, BUT I JUST FOUND OUT ABOUT IT AND I AM OBVIOUSLY CONCERNED ABOUT HER SAFETY.

DRIVING VEHICLE ON A CITY STREET IN DRIVE GEAR AND IT SLIPPED OUT OF DRIVE INTO NEUTRAL WITHOUT WARNING. TRIED TO PUT IT BACK IN DRIVE (AS I WAS ON THE ROAD) BUT EVERY TIME I SWITCHED GEARS BACK TO DRIVE AND RELEASED THE GEAR SHIFTER IT WOULD IMMEDIATELY POP BACK INTO NEUTRAL. I PARKED & TURNED THE CAR OFF, WAITED AND THEN TURNED IT BACK ON AGAIN. IT SEEMED TO BE OKAY SO I GOT ON THE FREEWAY HOME AND AFTER I MERGED INTO TRAFFIC THE SAME PROBLEM HAPPENED (BUT WHILE I WAS DRIVING AT A MUCH FASTER SPEED). I HAD TO HOLD THE GEAR SHIFT DOWN IN DRIVE THE ENTIRE RIDE HOME (WITH MY ONE YEAR OLD IN THE CAR). I GOT HOME AND AFTER I PARKED AND LET THE CAR SIT I WENT BACK OUT AND TRIED THE CAR AGAIN AND IT HAPPENED AGAIN. I CHECKED AND THE SAME PROBLEM HAPPENED IN REVERSE (IT WON'T STAY IN REVERSE, IT JUST POPS BACK INTO NEUTRAL).

UPON STARTING THE VEHICLE IT MAKES A HIGH-PITCHED BEEP, FOLLOWED BY A BUZZING SOUND THAT REPEATS EVERY FIVE TO EIGHT SECONDS. THE DASHBOARD DISPLAYS THE TPS, ABS, VSC, AND BRAKE LIGHTS. WHEN PUTTING THE VEHICLE IN DRIVE, THE HIGH-PITCH SOUND RETURNS FOR ONE TO TWO MINUTES. DURING THAT TIME THE BRAKE PEDAL BECOMES IMPOSSIBLE TO DEPRESS. IF THE ENGAGED, THE VEHICLE DOES NOT STOP UNTIL THE BRAKE PRESSURE RETURNS. ONCE THE SOUND STOPS, THE BRAKE PRESSURE RETURNS TO NORMAL. DIAGNOSIS FROM TOYOTA SHOWS: CODE C1256 = ACCUMULATOR LOW PRESSURE. CODE C1391 ABNORMAL LEAK OF ACCUMULATOR PRESSURE. ESTIMATE FOR REPAIRS = $2,811.72. AT PRESENT THE VEHICLE IS UNSAFE TO OPERATE AS TOYOTA ADVISED, IN THE VEHICLE'S CURRENT CONDITION THE BRAKE SYSTEM COULD FAIL AT ANY TIME.

Reading this record
2 deaths reported in complaints filed with NHTSA.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
Most recent recall on file: Jan 16, 2013. Source: NHTSA Office of Defects Investigation.
