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.
My dashboard brake, tire pressure, vsc and AB’s light came on while driving
Failed brake actuator. Toyota knows about the issue and refuses to honor any reasonable repair. Braking at any speed the car ferociously pulls to the left, throwing you into another lane or on coming traffic.
The engine light went on while driving on the highway. We immediately pulled over and had the vehicle towed to the nearest dealership. The dealership informed us that both the Brake Actuator (Toyota part TO44500-47141) and water pump (Toyota par TOG9020-47031) had failed. The car was no longer save to drive.
Car Mechanics say I need a new ABS actuator/pump costing about $4,400 at dealership and over $2500 at garages. Most quoting about $3500.00. It is a known fact that this is common on Pruises, which I am now learning. I feel Toyota should be reimbursing their consumer for this unexpected charge. My car has only about 60000 miles on the car. RIght now I have to park the car until I come up with the money. So have no invoice to attach until I do the repair.

ABs Light came on high pitched sound and brakes suddenly stopped working while driving making very unsafe driving conditions. i recently purchased this car as my second, 2nd generation prius but the abs recall was evidently not performed when it was recalled and extended. this puts me upside down in a loan because i have found the repairs will be $1000-$2000 and now I can not afford to drive it. the car is at my home and available for inspection upon request. i felt very unsafe last night and the abs light recently came on and was intermittently making the high pitch sound which was continuous last evening when i was driving when the brakes stopped functioning
Losing all breaking from abs dealership says $3000 to replace abs brake actuator module. I have been hearing from other second generation owners this is a common problem and it vecomes unsafe when you lose brake functioning in traffic additionally it was an extended warranty twice with no milage limitations but wondering why itvwasntvrecalled. Now I fear driving because u safe yet I am unable to afford to make the repair because I am unable to worker as delivery driver is my employment to generate income needed for repair.

The brake actuator is failing. This has been causing not only lower mpg, but uneven braking and sometime failed braking for the past several months. I have contacted Toyota and they said that the voluntary recall expired. I explained to them that the car was serviced at Toyota and was never given notice and that this is a danger to myself and my children. There are not only of hundred of documented incidents regarding the brake actuator failing, but there is also a new class action lawsuit against Toyota for the same issue with the newer generation Priuses.
Brakes or not working fully brake peddle is hard to press 2009 toyota prius YouTube says it is the brake actuator
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 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.
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.
I WAS DRIVING WHEN THE ABS, BRAKE SYSTEM, AND PARKING BRAKE LIGHT TURNED ON. THE BRAKES BECAME VERY MUSHY, I WAS TRYING TO STOP, AND I COULD HEAR THE BRAKE ACTUATOR MOTOR BUZZING AND MAKING A GROANING NOISE.
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.
MY CAR'S BRAKE ACTUATOR FAILED WHILE I WAS ON HIGHWAY. GLADLY NOTHING DANGEROUS HAPPENED BUT I AM CONCERNED OTHERS WILL FACE THE SIMILAR SITUATION WITH WORST SCENARIO. TOYOTA TOLD ME THE WARRANTY EXPIRED AND QUOTED ME $2600. PLEASE ASK TOYOTA TO EXTEND THE WARRANTY.
