Good afternoon everyone!!! So I did a search here and didn't find any posts about booster failure on a 2016 v. I did see some posts that had TSB that mentioned some 2015's, but nothing about 2016. I have notice on our 2016 v Trim 5 with 105K miles, that about every 20-30 seconds it sounds like the booster pump is running. This is while moving and/or parked. No lights on the dash, no noticeable braking issues. Also did see a post about TechStream w/cable on eBay for $20 and not sure if it's worth it to maybe "see" what's going on and not have to pay Dealership a diag fee. Anywho.... starting to ramble... Any ideas/help would be appreciated!!! V
Sounds like it's on its way out, with a little time still. Are you thinking to DIY? I wonder if it'd be possible (and worthwhile), to source and install replacement components yourself, then limp it down to dealership for Techstream brake bleed? Or if they'd even be ok with that.
Eventually it will run too long (several minutes) and code. Unless it just fails suddenly which is more common. You still have limited brakes at that point with no power assist and extended stopping distance. But it could stay as is for months or even years, it is a crap shoot. Even if the brake booster was still covered by warranty or a customer support program, Toyota would not help unless it coded first. The support program is still in place for covered cars for 10 years or 150,000 miles. The last update I saw was dated 2020 and covered were 2012-15 v's.
Thank you both for the replies!!!! Yeah I guess I'll keep a listen out to see if it gets worse. Since this is our "daily" I'll probably get the Dealership to do it. I'm sure it's not cheap but don't know. I do have some rapport with a Service Tech at the Dealership so maybe I can take the TSB and see if they can talk to Toyota or something. Cant hurt... Hence my question if there have been reports of this happening on 2016's. V
