Just got my CSP-ZJB mailing - brake booster malfunction

I just received to the letter too for my 2011. My letter says unlimited miles until Aug 31, 2021. After that its 10 yrs from first use or 150,000 miles, which ever comes first.

 

how much would the reimbursement be?

 

definitely. doesn't seem right, you should be reimbursed for a new one

 

It should be for the amount you paid in total for the repair.

Anyways, mine failed 4 years ago and it cost $3300. I sent Toyota all my neccesary documents via usps Priority Mail. Tracking says they delivered it on June 19. Just waiting now. AND SURPRISE!!! My 2nd Brake Booster just failed 1 hr ago before typing this. I hope the Prius prime does t have this problem because I've been shopping for one for the past 2 months already and the 2020s just arrived.

Edit: I'm gonna keep driving it without the brakebooster until they send me a check. Then if they do send me the check I'm going to bring the car to the dealer for them to see if they will fix it a 2nd time. Battery is also dead so I have all kinds of lights on my dash. Just waiting for a Prius prime axle AMD I'm trading in this junk for 1k.

 

ah well, if it isn't the brake booster, it will be something else. toyota aren't what they used to be

 

Does anyone know if it covers the “Prius V” as well? The letter lists the “Prius PHV” but not the Prius V even thought the V is mechanically the same etc.

 

Think it's time to flush my brake fluid again.

 

How often does it honk/bark, mine does it on every spirited non conservative braking, worried if this a failure waiting to happen or just a new noise have to live with it, unfortunately Toyota won't replace it as there is no error codes.

 

I flush my brakes as part of preventative maintenance. So many here think "Prius" DOT 3 fluid is lifetime...it is not...as might be evidenced by said failures. But that's just me...I turn a wrench for a living, so what do I know.

 

FWIW, the dealership changed our brake fluid sometime in 2013, I did again, in the fall of 2016, and will likely be doing again this fall.

And I've hear the "honk" when coming to a stop, with moderate braking. I actually had an appointment set up, to have them test drive. The car seemed to get wind of it somehow, stopped making the noise. So I cancelled, for now.

Bottom line: there is something inherently defective in some of the brake boosters, some fail, and frequent changes of brake fluid, while a good idea, is not a panacea for the brake booster problem.

 

Panacea? Maybe not, but you and I both know what preventative maintenance is. With all the "brake problems" Prii have had...it's just common sense.

 

i don't do any spirited braking. i wonder if that's part of it

 

That would then make it an NTSB thing if that's the case...but I doubt spirited braking is the cause. I've had two Prii now and I drive normal...in the city no less...without a brake issue yet. Who knows.

 

Anyone, would be interesting to know whose had this 'honk' issue the longest,

 

oh man, that issue goes way back in gen 2, with no ill effects in most cases

H᠎i, welcome to PriusChat, where a lot of people come looking for accurate information about their Prius cars.

The 'campaign ZJB' document linked above applies only to 3rd generation Prius liftback and Prius Plug-in (PHV) cars, not to the v or the c. The end dates vary by model year:



So it's already over for 2010s (unless anybody's got one that hasn't rolled 150k by now).

For 2011s through 15s, it is still in force through August 2021 and then to your tenth year or 150k miles, whichever comes first.

It is a replacement conditioned on specific failures ("certain internal malfunctions of the brake booster and brake booster pump assemblies"). It is good to remember that in the 3rd generation Prius, those are two different assemblies:



There is a list of trouble codes that may mean the covered failure has occurred. They are codes that can also be set for other reasons. Sometimes a few simple steps of diagnosis will reveal that something else has caused the codes you have, and that replacement of one or even both these assemblies would not be the necessary solution.
