2009 Toyota Prius

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

Cooling system

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.

Breaking system failure do to ASB Actuator, breaks are locking and vehicle is engine braking.

When I am coming to a stop or need to put on my brakes my car will accelerate at a jump ahead pace As if to take off instead of slowing down and stopping. Regardless whether I’m turning a corner or I’m continuing straight when I have to Put on the brakes it speeds up instead.

In the 2009 Toyota Series II vehicle there are two parts for the brake actuator pump assembly which has been cycling about every 20 seconds for the past six months or more. There is an intermittent tone when depressing the brake pedal before starting the car (engine off). The Brake dash warning light is on continuously. Occasional loss of brake power in reverse causing the driver to re-apply the brakes to stop unwanted motion of the vehicle.

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.

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.

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

Apparently a known issue with the HID lights coming on or off intermittently.

The front lights and break lights sometimes turn off while I am driving. Both of the lights or one of them.
