    2012 Prius.

    My brake booster failed and was replaced under warranty extension at 7 years (11/2019) and 133k miles.

    I just reached 200k last week and the accumulator/ booster is demonstrating all the signs of failure again!

    Anyone experience this? I’ve searched, but cannot find anything. I’m shocked and disappointed the Toyota warranty replacement died after 5 years and 67k miles.

    As a frame of reference to my rising anger, I just put a new head gasket in it last April and a new battery in 2021.

    Considering this car has 200k miles and is 13 years old, parts will fail and more parts are going to fail.

    Not a lifetime keeper like many others have been in past . You don't do this anymore especially after 2010 cars aren't made for this planned obsolescence

    Have you gone back to where you had the booster accumulator brake parts on the firewall replaced and ask them something? I'd be curious to know what they have to say about it I mean those parts are only what four years old now or something 2019 on 5 years old whatever certainly not Toyota's normal interval for parts to last generally not in my life anyway this is new stuff for the pre-planned obsolescence stage 2010 and forward this is all new to me. I quickly got out of two generation 3s as fast as possible once I realized kind of what was happening but it's happening across the board to everybody so you're either going old or you're picking up someone else's problems whatever dealer or whatever car manufacturer you use look at Kia and Hyundai other GDI engines used in other vehicles the EcoBoost etc everybody has got these serious problems trying to ring out the last 1/10 of a mile to a gallon of fuel they let everything go and the only prize that's in the eyesight is miles per gallon longevity and lasting of the vehicle is completely out the window I mean look at the insides of these cars they're made to go around the block a few times and the kids car seat in the back a few times and then they look like you should never get in them again might be something growing in there

    I put every mile on this car and maintained it by the manual.

    The original brake parts were replaced by Toyota as part of the ZJB warranty enhancement around 67k ago.

    I am staggered that a Toyota part (subject to a huge campaign) is failing this quickly.

    You're too kind, thinking they actually have a plan. I think they're just not testing enough, letting their customers do that, the hard way, with the brake booster, low-tension piston rings and the EGR.

    But I thought he said it was done at the dealer part of the campaign and of course when he left with the car I'm assuming 67,000 mi of no lights on I would hope the old part wouldn't do that after it had come in and the lights were on and oh boy what a mess.

    i don't mean the old part as in, they took it out and put it back in, or repaired it in some way.

    i mean they might have had parts in stock before whatever updates toyota did to fix them, and put one of those in by mistake

    Allegedly they used part number 04006-22147 and 04008-11347. It was part of the ZJB003 campaign.


    It worked for 67,000 miles and then it is malfunctioning again.

    I thought they would have improved the design or manufacture of the parts in some capacity?

    I have been replacing parts on this thing knowing that of the trifecta of major problems that one was done.

    If your second brake booster has not coded yet I would get a brake booster flush and see how long it lasts.

    I would be more worried about a second head gasket.

    Not sure where the idea started that 13 year old gen3 hybrids can be made reliable by simply replacing parts or cleaning egrs. It's more complex than defective parts; it's flawed engineering that was redesigned successfully in gen4.

    It’s been reliable except for the brake booster(s), hybrid battery, and the head gasket. . . . . . .
