2019-2020 Prime brake assist recall

the hits just keep on coming

 

I saw this yesterday. Man, Toyota needs to step it up with it's 3rd party vendors. This is going to cost them.

 

i wonder if the brake components are too complicated to successfully mass produce?

 

Good question. My 2015 hasn't been hit with any recall issues that I am aware of yet. I hope it stays that way.

 

just a bad run maybe

 

Brake booster pumps have been used in diesels for as long as diesels have had power boosted brakes. The pumps and accumilators are also in turbocharged gas engines.

 

From RMISC-19V544-8456.pdf linked on the NHTSA page:

and as to the cause:

 

Maybe a different supplier.

 

welp time to take in my vehicle

 

Hmm, I guess they did give a production date range for the cars. I overlooked it the first time.

 

My ‘20 isn’t part of the recall. You can plug your VIN in on that site above to see if you’re affected.

 

The 4runner has had an electric brake booster since 2003, I think. It is surprisingly reliable even though it seems like it wouldn't be. But if it fails it's really bad (can lose power brakes) and really expensive to replace ($700 used or $2000+ new).

 

My first car didn't even have power brakes to lose. My next two did, but they were vacuum-based and could only give you maybe two or three banked-up brake strokes if the engine stalled and stopped pulling vacuum, and they had no warning beep.

The electric-pumped accumulator in the Prius holds enough fluid under pressure for around thirty uses of the brake with full power assist if the pump stops working ... and for the last ten or fifteen of those, you'll have the infernal beeping to warn you that something's not right.

 

I didn't know that. This is good to know.

 

Never counted them in the turbo Sonic, but had far more powered brake applications without engine power than the one or two in a naturally aspirated car.

 

Trying to set up a new service record data on the DriverSide page, I just noticed there is a safety recall on 2020 Prius Prime. I checked at NHTSA site, but my 2020 Prime LE was not affected. The recall was already out last year 2019-07-24, I wonder how many 2020 models were affected?

 

Completely different operation. Break booster on hybrids can't rely on vacuum from the engine, at least Toyota. By the way those hydroboosters in Ford and dodge diesels are completely crap.
