Eight problems related to brake abs warning light have been reported for the 2011 Toyota Prius. The most recently reported issues are listed below.
Brake/trac/abs lights on and will not turn off when parked or in motion. The lights came on the next day after parking overnight. Hybrid battery not recharging from braking. Car makes a whirring sound every 2-3 seconds, seems to be coming from the braking system. Feels unsafe to drive since braking distance feels longer. Car has about 197,000 miles.
Brake, traction control, tire pressure, abs lights all come on while driving. Took to shop. Claims it's the brake booster/ actuator problem. Customer support program.
My car spontaneously started showing the abs system warning light, the "brake" light, and the electronic stability control indicator light without warning while parked. As soon as this happened and I put it in motion, the car began responding poorly to braking, with increased pressure and lack of responsiveness. Additionally, the car is receiving barely any battery charge from the brakes (a small amount compared to the normally full charge), and a whirring noise can be heard about every 3 seconds ( the same whirring noise that occurs when the car is starting up, which I think may be related to the battery). This issue happened while the car was at rest, and affects the car while in motion and at rest. The car feels unsafe to drive due to unpredictability with the brakes and their effectiveness. I believe this issue may be associated with the brake actuator.
Abs lights on ,tracks warning lights on and vsc lights on . Its a serious problem. Toyota should fix it . Toyota should own its problem.
My car only had 120k miles and the break boostor and actuator breaks down while we were on the road. My wife drives the car with my 3-childrens. She was almost hit the other car on highway because the breaks system stops working at normal mode. The dash board shows all kinds of break, traction control, and abs lights . This is a life threatning issue and toyot needs to replace this part with no charge becasue it has a manufacturing defects and thousands of Prius owner has the same issu.
The traction control, abs light and warning light all came which I believe all to be a safety issue.
I was driving at about 35 mph and all of a sudden my brakes stopped working. The brake , abs and traction lights came on all at once. I somehow made it home but I could have easily crashed. I had my 9 year old in the back seat and he also got very scared. Now I cannot drive my car and the brakes feel as they as stuck and very hard. I took my car to a reputable mechanic and he told me it is giving him code c1391. This is the same problem that the 2010 Prius had under the recall. My Prius is 2011 and not under the recall. I feel that the 2011 should be under recall because many thousands of lives are in danger now.
Traction control and abs warning lights came on. Cruise control stopped working. Took it to Toyota who said codes indicated failure of master cylinder. Cost of repair $3,400. I think they have a defective part problem.
