2010 TOYOTA PRIUS Complaints

ABS pump booster failed. Hard to stop the vehicle. Almost had an incident. Trouble code C1391.

My ABS, break and anti-skid lights came on while my vehicle was parked. The ABS system shouldn't fail on a car. Many other 2010 Prius owners have reported the same problem. Toyota had break system recalls back in 2010 and 2013. I believe my car may should have been part of the recall, but was overlooked.

I took my vehicle to my mechanic at my independent service center because I experienced shaking/significant vibrating at 60 mph. I had also experienced a loud noise that only lasted about 2 miles. He found that the right rear brake unit, specifically the caliper, had seized. I contacted Toyota of America because there was no brake warning light to alert us of this situation. I received a call back from David from Sloane Toyota in Glenside, PA, who confirmed that the caliper seizing would not cause the brake warning light to appear. He also indicated that the caliper is not something that is routinely checked as part of state inspection, or the regular maintenance schedule. I am deeply concerned that this mechanical failure of the brake unit could have resulted in death(s). I request that Toyota vehicle owners and mechanics be alerted to this, specifically the fact that the brake warning light does not alert a driver of this brake part failure. Further, I request that an inspection of the calipers be included in the routine maintenance schedule and annual state inspection. Thank you for the work that you do to keep us safe!

ABS brake booster failure. Vehicle with approximately 140,000 miles. Previous safety notice expired that covered 10 years or 150,000 miles

The contact owns a 2010 Toyota Prius. The contact stated that while driving at an undisclosed speed, the ABS warning light and two other unknown warning lights illuminated. The contact stated that the brake pedal went to the floorboard while depressed. Additionally, the contact stated that while self-inspecting the vehicle, he became aware that there was no brake fluid in the brake fluid reservoir. The contact stated that when the vehicle was self-inspected for a second time that same day, the brake fluid was full. The vehicle was taken to an independent mechanic, who informed the contact of an unknown recall for the brake booster. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 85,000.

The braking system developed a leak in the accumulator causing the whole braking system to fail and turn the abs light on in the car as it leaked brake fluid into the brake booster from the master cylinder

There was some kickback or resistance when engaging the brake to start the car. When the car turned on, the brake light, ABS light, and traction control light lit up. I took the car to Toyota service, they stated that the brake booster pump was defective and needs replacement. I see that there is not an open recall for this vehicle, however there was a recall #13V235000 that was sent out in 2013 with the exact same issue for 2010 Toyota Prius. We bought the car as a certified Pre Own in 2015, so we did not get this notification. I am trying to figure out why this car does not fall under the recall category? Thank you.

Hybrid system shut down while driving. Cleared at deal ship twice. happened two more time. Dealership claims they were unable to recreate the issue.

Took my car to Toyota dealership to get remedy J0V NHSTA recall ID NO. 18V684 Fixed. Dealership has refused to work on recall and has told me I need to pay out of pocket for repair because my car does not fall into certain codes yet it’s a specific recall that needs to be done on my vehicle

My Prius 2010 has thrown the ABS, Traction, and Brake HUD lights all together. I took it to an Autozone and scanned the code to get the C1391: Abnormal Leak of ACC PRESS error. Many Prius 2010 have this issue, I'm sure I'll need to replace the actuator and/or accumulator and I know that will cost a good bit, i hope Toyota could help us fix it.
