Three problems related to abs brake fail have been reported for the 2006 Toyota Prius. The most recently reported issues are listed below.
Abs actuator failure. There was a recall that was good until 2017 and 150k miles. My vehicle has 192k miles. I was backing out of my driveway and the three abs ligths came on and my brakes failed. I scanned the computer using an obd and it indicated failure.
My vehicle has a defective abs actuator, a part previously under recall by the manufacturer-Toyota. (2006 Toyota Prius abs part, actuator complete assembly, id 44510-47050) warning lights: master warning abs brake system: codes: p0571, c1256, c1391. This defective braking component makes my vehicle extremely unsafe to drive along with thousands of other Toyota vehicles on the road today. This abs actuator can fail at any time and at any speed. Toyota previously launched an extended warranty campaign for this same part on a percentage of vehicles, but purposefully excluded thousands of vulnerable drivers from getting necessary repairs. Toyota has refused to replace this part in thousands of unsafe vehicles even while they acknowledge it was manufactured with known defects. This part is worth nearly the trade-in amount of my vehicle. Toyota is deliberately keeping unsafe vehicles on the road, with a known issue.
The abs actuator is failing to prime causing the anti-lock brakes to slip and the brakes not to engage. This has happened multiple times while both stationary and driving. I see that Toyota had extended warranty related to this issue however that expired 12/31/2017. My issue started in January of 2018. I have attached a copy of the warranty enhancement for reference.
