2007 Toyota Prius brake problems

SERVICE BRAKES

The brake actuator failed. When the car was diagnosed by the Toyota dealership, they identified the problem as an internal leak within the brake actuator. Luckily, nobody has been hurt attempting to drive the car, but it is still being driven to get it from home to the repair shop so anything is possible. The first symptom I could link to this was in 2023, when the car would not accelerate via the gas pedal after the brakes were pressed during cruise control. Turning off the car and turning it back on fixed the problem. Afterwards, the red brake symbol was turned on. From that point on, the brake light would only shine sometimes. leading me to believe there must not have been something wrong with the car, since nothing else happened after that. 2024 is when the red brake light and ABS symbol both lit up. The only information that I could find in the manual was to take the Prius to the Toyota dealership. I could not find details on the problem. I continued to drive the car regardless because there seemed to be no problem. After letting the car sit for a few months in 2025, I began driving it again, and it was fine. A month later, I turned on my car and was met with a loud beep that did not end. This was my final sign to take it to get repaired. The car has exceeded 200,000 miles. This fix is $3,205.40 at the dealership. My 2007 Toyota Prius is valued between $2k to $4k. The repair would cost more than simply buying another Prius.

Check engine light came on with codes C 1256 & C 1300. Primary issue is Brake actuator failure. Toyota is ignoring this known and repeated issue and it may lead to a dangerous/ deadly situation if brakes go out while driving.

There is a known, (by Toyota), issue with the ABS brake actuator in many Prius generations including the 2nd generation Prius that I own. My mechanic said it would cost @$3000 to fix. This as I said is and has been a known issue with these cars that affects the ABS braking and puts myself, my family and any one on the road near me in danger. Toyota was quietly replacing these under an unadvertised, extended warranty program. Mine is out of this so called warranty period but if this was a known issue and was corrected at no cost due to the fact Toyota knew there was an issue why was there never a recall on the affected models all with this same problem? I feel that this dangerous problem should be corrected by Toyota at no cost to the owners of their dangerous affected vehicles.

Brake Actuator system (ABS) needs to be replaced with only 133K miles on my 2007 prius. I heard a sound and had a Toyota service center check for any issues. They told me it was the ABS system that needed to be replaced at a cost of $5K. The repair costs are greater than the car value. Toyota knows about this year, make, and model issue. I contacted Toyota Corporate about this this week and learned there was an extended warranty for this specific issue on my car. They refuse to honor the extended ABS system warranty even though I'm under 150K miles per the warranty. They told me a letter was sent to me about replacing it at no cost in 2017. I never received the letter nor did the Toyota service center I used at the time tell me about the issue. Additional Info: I am not driving the car since the dash lights have come on - red triangle, check engine, VSC and (!) symbol - with a circle inside the (). Noise checked at Toyota dealer service center and confirmed it's the brake actuator system No inspection by the manufacturer, police, insurance rep, or others The sound came first when pressing the brake pedal and then the lights came on after taking to the service center

Due to water infiltration from a poorly manufactured hatchback, water is able to get inside the "Supply Assy, Brake Control Power" module in the trunk of the second generation Prius. This part ultimately shorts out and fails causing a loss of regenerative braking and a "brake warning light". Toyota seems to be aware of the problem as a replacement module is now sold in a "water proof sheet" (see attached). Toyota has also moved this module to a different location (away from the rear wall of the Prius) in other hybrid vehicles (such as in the Camry where it has been moved forward). I wonder if the hybrid batteries in the Prius also fail due to water infiltration in the rear sections of these cars.

Toyota has admitted that their BRAKE ACTUATOR assembly on their 2007 Prius FAILS and they will fix it for no charge BUT ONLY IF YOU COMPLAIN. The brake actuator on my 2007 Prius is now failing and the braking system has become UNRELIABLE and UNSAFE. Toyota should replace my failing brake actuator with a new unit for no cost because this is a SAFETY ISSUE. I refuse to pay $3000 out of my own pocket to repair an item which has a long history of FAILING.

SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP:ABS WARNING LIGHT

The contact owns a 2007 Toyota Prius. The contact stated that while driving the speed was unknown due to the instrument cluster being inoperable. On another occasion while driving approximately 45 MPH, the brake pedal was depressed but failed to operate properly; however, on that occasion the instrument cluster was operating as designed. The vehicle stability control, ABS, and brake light warning lights were illuminated. The vehicle was taken to an independent mechanic and diagnosed with an actuator and brake booster failure. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 203,202.

Brake Actuator Re. Vin: [XXX] On 4/13/21 my Toyota Prius '07 was diagnosed by Toyota of Hollywood of a bad abs actuator that needs to be replaced. The fact of the matter is that about 28 months before that on 2/14/19 the Actuator assembly was replaced by Toyota of North Miami after being diagnosed first by Toyota of Hollywood. The reason I choose to do the job in north Miami is because it was less costly. My question is how can a genuine Toyota part fail in just 28 months.? Many Prius owners have been experiencing this safety issue since 2018. The warranty enhancement program ended before the fact in 2017. And there seem to be a misprint because how can the Secondary Coverage end on the same date as the Primary Coverage? (2017) When you use the date of first use of a 2007 Prius. Toyota needs to do another Recall for this safety problem. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

MY CAR HAS ONLY 65,000 MILES ON IT AND THE ABS ACTUATOR HAS FAILED. BEFORE GETTING IT REPAIRED, THERE WERE MANY INSTANCES WHEN THE BRAKING POWER WAS SIGNIFICANTLY REDUCED. THIS IS CLEARLY A SAFETY ISSUE THAT TOYOTA IS AWARE OF, BUT NOT WILLING TO REPAIR. I AM SHOCKED THAT THERE HAS BEEN NO RECALL.

ABS ACTUATOR FAILURE AT ONLY 64,000 MILES. POTENTIAL FOR COMPLETE BREAK FAILURE IF NOT IMMEDIATELY ADDRESSED. TOYOTA IS AWARE OF THE ISSUE AS THERE IS A TSB, BUT THEY ARE CHARGING THOUSANDS OF DOLLARS FOR A REPAIR FOR A SAFETY CRITICAL ITEM THAT IS DUE TO A MANUFACTURING DEFECT. THIS SHOULD BE COVERED UNDER A RECALL.

STARTED GETTING BRAKE ACTUATOR FAILURE NOISES IN MY 2007 PRIUS BACK IN MARCH 2020 AND TOOK IT TO THE WEST COAST TOYOTA DEALERSHIP IN LONG BEACH, CA. THEY DIDN'T FIND ANYTHING WRONG WITH THE ABS SYSTEM EVEN THOUGH THE GRINDING NOISE I NOW KNOW IS COMMONLY ASSOCIATED WITH THE PROBLEM WAS GOING OFF. THE OTHER DAY THE ABS LIGHT WARNING CAME ON AS WELL AS THE EMERGENCY BRAKE LIGHT. I PULLED OVER ON WASHINGTON BLVD AND ARLINGTON IN LOS ANGELES AND WHEN I STARTED THE CAR AGAIN AND STARTED TO MOVE FORWARD I HAD NO CONTROL OF THE BRAKES AND TURNED THE CAR OFF IMMEDIATELY. FROM WHAT I'VE READ THIS IS EXTREMELY COMMON! TOYOTA EXTENDED THE WARRANTY'S ON MANY OF THEIR VEHICLES TO 10 YEARS BUT THERE WERE NO RECALLS SO IF THIS PART MALFUNCTIONS A DAY AFTER THE WARRANTY THEN YOU ARE OUT OF LUCK. THE BRAKE SYSTEM IS JUST ABOUT THE MOST DANGEROUS PART TO FAIL. I CAN'T IMAGINE WHAT WOULD HAVE HAPPENED IF THE SAME THING HAPPENED AT A HIGHER SPEED.

I WAS DRIVING DOWN THE HIGHWAY AT ABOUT 70 MPH WHEN THE BREAK LIGHT, ABS LIGHT, AND TIRE LIGHT ALL CAME ON ACCOMPANIED BY A HIGH PITCH BEEPING. AS I ATTEMPTED TO PULL OVER THE BREAKS WERE ALMOST COMPLETELY UNRESPONSIVE. WHEN I CONTACTED TOYOTA ABOUT THE ISSUE THEY LET ME KNOW IT WAS A PROBLEM THEY WERE AWARE OF THE ISSUE BUT DIDN'T BELIEVE THAT HAVING YOUR BREAKS GO OUT WAS GROUNDS FOR A RECALL. I WAS ALMOST INVOLVED IN A HIGH SPEED CRASH WITHOUT THE ABILITY TO STOP BECAUSE OF THIS.

WHILE DRIVING AROUND A CORNER ON CITY STREETS, BRAKING SUDDENLY BECAME VERY DIFFICULT, AND CAUSED THE VEHICLE TO SKID WHEN BRAKES WERE APPLIED. A HIGH-PITCHED ELECTRONIC SQUEAL CAME FROM THE DASHBOARD, AND THE BRAKE SYSTEM LIGHT, ABS LIGHT, VSC LIGHT, AND MASTER WARNING LIGHT ALL TURNED ON. THESE ARE ALL LISTED AS SYMPTOMS OF A FAILED BRAKE ACTUATOR. AFTER CONTACTING A LICENSED TOYOTA DEALERSHIP, I WAS DIRECTED TO THE TOYOTA CUSTOMER CARE DEPARTMENT. AFTER BEING ESCALATED TO A SUPERVISOR, I WAS INFORMED THAT TOYOTA IS AWARE OF THIS PROBLEM, BUT THAT THE WARRANTY EXTENSION THEY USED TO COVER IT EXPIRED IN 2017, AND THEY REFUSED TO COVER THE COST OF REPLACEMENT (~$3000). I BELIEVE THIS ISSUE SHOULD BE CAUSE FOR A SAFETY RECALL, AS IT HAPPENED SUDDENLY AND WITHOUT WARNING WHILE THE VEHICLE WAS IN MOTION. IT WAS PURE LUCK THAT THIS DIDN'T RESULT IN A CRASH.

I WAS DRIVING MY CAR ON THE HIGHWAY AND SUDDENLY MY BRAKE WARNING LIGHT, ABS WARNING LIGHT, AND OTHER LIGHTS CAME ON AS WELL AS A CONSTANT BEEPING NOISE. THE BRAKES ALMOST STOPPED WORKING COMPLETELY; IT ONLY WORKED ABOUT 10%. MY FOOT WAS ALL THE WAY DOWN ON THE BRAKE PEDAL, BUT THE CAR WAS STILL MOVING. I WAS ABLE TO PULL OVER, BUT THIS ISSUE LEFT ME IN A COMPROMISING POSITION FOR MY SAFETY AND COULD EASILY HAVE BEEN INVOLVED IN A SERIOUS ACCIDENT FROM IT. THE WARNING LIGHTS GO AWAY AFTER TURNING OFF THE CAR, BUT THEN THEY COME BACK ON RANDOMLY. BASED ON WHAT I'VE READ ONLINE ON SIMILAR ISSUES, I BELIEVE THIS IS AN ISSUE WITH THE BRAKE ACTUATOR.
