GM under investigation for faulty brake vacuum pumps

[sk]

Mine was replaced under warranty (but I had to argue with the dealer since they said they couldn't recreate the issue).  I attached a copy of the PI but there may be a newer version of it by now.  There are 5 or 6 things they are supposed to replace and yes the bill is almost $1000 if you have to pay out of pocket.

I had it happen 3 or 4 times before the repair.  I now have almost 10,000 miles on after this repair and it has not happened since (fingers crossed).

Interesting gm says the stretchy belt is not reusable but it does not look like they replaced dave07

my truck is doing this now. If you pump the brake 3 or 4 times by the 4th time it doesn't have any breaking power. Im out of warranty and if they don't fix it for free I guess ill just have to get into an accident. I can already feel my neck and back hurting....

Bring it in. There is Tech Bulletin for this, and they WILL fix it...Trust me.

I had this problem 2 days ago. I was going into a Valet in a restaurant when my brakes went stiff on a 2017 GMC 1500 Sierra. Almost hit the lady in front of me.

I recently wrote off my 2015 silverado. 0 percent liable but should i be questioning if my brakes were good? I recently came across this thread. Went through the thbread  and the sympton's described was a few occurrences thats happened to me while owning the vehicle no longer than 8 months. 

 

Thanks.

This is where we are at. Looks like you should fall into the mileage range for getting it fixed

So if you fall within time and mileage for special coverage, is this a guarantee free warranty or does it only apply to those who report problems.

In other words, is GM replacing these Vacuum Pumps just as a precaution knowing they are bad?

I’m sure you bring it in when/if it F’s up &  they would have to diagnose it then repair it. Otherwise it would just be a recall if they were going to fix every one of them. Basically extending the 3/36 warranty on the vacuum pump only since like most things it doesn’t fall under power train.

my 2014 is getting repaired right now. Almost $900 parts and labor.
