Letter from GM on 2014 and up Sierra Vacuum pump failures

[pewterliftedz]

There are already 4 or 5 threads about this topic, I just got mine changed out this week. I just went in and told them the brake pedal feels hard sometimes, and they changed the pump no questions asked.  I am still under factory warranty on my 17'

I would get a stiff pedal when I would first start up the truck, and a audible high pitched sound at the same time.  I think it was my truck warning me about low vacuum.  It was rare though, but I did have a constant tick coming from the engine bay.  The tick is gone now that the pump has been changed.

Got my letter....thanks!  But no thanks...84K miles!  I change my oil every 10K...Vacuum pump should have failed years ago?  Wait maybe it's failing right now?  What do I care?  Not like I will have any Dealer install it charge me 1K and probably F' something else up....Or I will just drive it like I do with every other vehicle for another 30K before I actually do something about it?

I'm not surprised they're not providing a recall, even with a safety function like the brakes. Extended warranties seems to be the way manufacturers go if they can get away with it. I owned a Lexus LS460, their brake actuators would fail. Lexus would not recall them despite it bei a common and dangerous issue. Instead they extended the warranties on them for a few years and a certain mileage threshold. Once you were out of that you were on the hook for the repair yourself. It was a $3,500 dollar repair. Mine was starting to go - out of extended warranty of course - I traded it in and got rid of the headache. Spending $3,500 for a part that isn't a major component like a transmission or engine is too rich for my blood.
