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…

Brake actuator malfunctioned and caused me to hit a parked car in my driveway (backing up). Even though i have less than 130k miles on my vehicle, it is a year after the extended warranty i am responsible for paying the $3k repair. The negligence by toyota in handling this recall is terrible and life threatening. There should be a class action suit against toyota for the hundreds of injuries and damages by their…

Failing brake actuator assembly that toyota knew was defective. They extended warranty through 2017, but the issue happens around 200,000 miles. Now that the extended warranty has expired toyota is charging $2300 to replace this known and defective part.

I just found out yesterday after a visit to a toyota dealership service center that the abs brake actuator on my 2009 prius has failed and needs to be replaced. I was quoted at $1750 for the part and $605 for the labor, pre-tax. I did some additional research on this issue and found that there was a warranty enhancement program ' zg1 specifically for this part and issue.…

Abs pump went bad. Also when braking hard, the car will let go of the brakes. Turning on the car and immediately reversing the car brakes will not work until after everything is loaded in the car. Making backing up dangerous.

My abs, traction control, and master brake light came up on the dash. The problem is a failing brake actuator, which is a known issue by toyota. Spoke to toyota a dwas told that i am out of their ten year extended warrenty for this issue and it would be a roughly $2700 repair. Why this brake actuator was never placed as a recall is beyond me as a complete failure is an accident waiting to happen. Toyota refuses to…

Abs actuator. The diaphragm in the brake accumulator fails. This is a known recall. However mine is beyond their extended warranty on the recall of both past ten years and past 175000. Dealer estimate was $2500 to repair. This is an essential safety recall due to the fact that when it completely fails the vehicle loses powered braking leaving only emergency brakes and engine braking mode which are inadequate and not…

The abs and other brake warning lights go on randomly and the brakes become stiff. Took the vehicle to the toyota dealership and they said it is due to the brake actuator assembly. The abs actuator assembly part was part of an extended toyota warranty under notification zg1. However my vehicle just missed the deadline for the warranty by three months. This is a safety issue for toyota as they know this part has a…

My prius now has all those dash lights on: !, abs, vcs. I was driving yesterday, on a city street and the lights came on, and the brakes suddenly did not work-hard to push. For months, when i would drive over rough terrain, i had the loss of braking, accelerating, and the slick road icon would illuminate. The is exactly the same abs module problem affecting 2010 prius, ands needs to be recalled and repairs…

Our prius started making this noise recent... 4 seconds of spinning clicking, then quiet for 5 seconds then repeat. Happens while driving, while parked and i just went out there with my keys in my pocket and opened the door and it started making the noise when the engine starts...so does the rattling and knocking sounds. When i hit on brake, the brake makes very annoying noise.

Prius dashboard lights up with brake light, abs and vsc light. Ran diagnostic codes and took to dealership- said vehicle was part of brake actuator manufacturer malfunction. Dealership would not resolve issue despite acknowledging that it was a manufacture defect. Concerned for my safety because brakes are not working well. Called customer service and they wont do anything.

When braking hard, the brakes lose all pressure, go straight to the floor and warning lights come on. As soon as brakes are released the lights go off and brakes again have pressure again. Toyota extended the warranty on this part, but it is was expired before problems arose.

I was driving my 2009 toyota prius on a very cold day (roughly 10 to 20 degrees f). The red brake warning light was on, along with the abs, vcs and yellow "!" lights. The brakes were extremely soft for about the first 5-10 minutes of operation. I would push the brake pedal as far as it would go (it would not go all the way to the floor) and the brakes would seems to be engaging at about 30%-50% of their normal…

Toyota knows there is a systemic issue with the break actuator assembly in 2004-2009 model year prius vehicles, and have issued a "warranty enhancement program - zg1" to extend the warranty coverage for repairs related to this part. My car is currently experiencing a malfunction in this part, but toyota is unwilling to honor the warranty because there are no warning lights appearing on the dash. The breaks feel like…
