My prius is behaving weird from the last few days.... First abs, (!), and parking brake lights poped and today check engine and triangle of doom showed up too.... Please guide as my dealership is suggesting change of some abs motor to resolve issue which is going to cost me 1000$.
you will need a prius trouble code reader to track down the problem(s). how many miles on her? have you tested the 12 volt battery?
It sounds like the brake actuator pump has failed. There is an extended warranty available in the US for that part. I hope you can get similar service where you live. Replacing that pump looks difficult, as is bleeding the hydraulic system, so it's probably best left to the dealer. If you can get the diagnostic codes from your dealer and post them here, we wouldn't be guessing.
I'd add that, so far, the only reason it "sounds like the brake actuator pump has failed" is because that's what the dealer's reported to have said. There's nothing else yet in this post to draw that (or any) conclusion, and yes, the trouble codes would be the first and most helpful information to add. -Chap
Yes it sounds like it could be the brake actuator issue Brake Actuator Assem - Warranty Enhancement | PriusChat Not sure if that impacted 2009 model year (Gen2 in USA had 2009 as last model year)
