My invoice says they measured the vacuum pump at 3 where it was supposed to be like 27. If you give them the tsb number and tell them the brakes get hard after repeated slow speed stops that should be all they need.

Was it a quick repair?  Same day, next day?

 

Thanks for the info...

I dropped mine off at 10 and picked it up at end of day. It's probably a 2.5 hour repair. If I did it, it would be 5 hours.

I have a early appointment Wednesday.  Cross my fingers.  
Print out the tsb and bring it with you. They need to check upstream from the vacuum pump to make sure oil didn't get into other brake parts

Sounds like the hard / stiff brake pedal issue caused by the vacuum assist pump is headed closer to a recall. Almost 500 official complaints to NHTSA so far. They are rolling in 1 to 2 complaints a day.

 

Check out this letter to GM

Yep, I just spent $1,700 replacing the pump & brake booster last week. 2 weeks before that, dropped another $1,700 to replace cracked HVAC condenser & compressor. And in January the HMI for the touchscreen sh** the bed for a whopping $1,800. I do have 80k Highway miles on the truck but they’re gentle miles & the interior still looks/smells new. I have an ‘04 Sierra with over 200k on it & only had to replace an instrument cluster. I logged a complaint with NHTSA on the brake issue, so hopefully I’ll get reimbursed for some of that cost soon, but not holding my breath. For $50k, these trucks sure are temperamental.

Well on the bright side, you knocked all the problems out at once. It should be smooth sailing from here. The 100,000 mile 7 year warranty was about $3900 when I bought my truck which seems like a lot but repairs like yours make them worth the calculated gamble.

I was a victim of this defect. I had mine replaced under warranty as it was out of specs.

Did you report it to NHTSA?

I just had mine replaced by the dealer. There is a "special policy" warranty set up for this problem. Mine was paid for by GM even though I have 70k on my 2015 Silverado. Check with your dealer before you repair it. I will go ahead and report mine.

Yours was under the 72K requirement.

Unfortunately after 5-6 years most K2 owners are not.

I  received my letter announcing the special coverage for the "increased brake pedal effort" yesterday.  Has anyone else received this notice? 

 

Coincidentally, on April 19th, I experienced a very severe "hard brake pedal" while going thru a drive-thru.  In ~51,000 miles, this is the 2nd time this problem has occurred.  This last instance was quite memorable.  i am a large guy and had to use a lot of force on the pedal to keep the vehicle from rolling forward while idling in drive.  I honestly don't believe my 120 lb wife could have applied enough force to keep the vehicle stationary.  The April 19th "hard pedal" lasted several minutes thru many brake applications while idling in drive.  With cars ahead and people walking in-front of vehicle in the drive-thru, I wasn't about to troubleshoot and experiment with different engine RPM to see if vacuum could be restored.  Shutting vehicle off and turning back on did not restore the braking.  

 

A quick internet search quickly yielded volumes of info regarding this issue.  I reported the safety problem thru  NHTSA's website on 4/20/19.  Kind of interesting that less then 2 weeks later the special coverage notice is received by mail. 

 

Does anyone know if dealer can identify faulty vacuum pump with so few occurrences of failure over 3.5 years?  I dread being charged for something that very clearly matches the described hard brake pedal condition though would unlikely be able to be duplicated.  My vehicle did not throw a DTC code or "Service brake assist" alert as mentioned in the Notice.  Also, the Notice mentioning "failing to follow recommended oil change intervals" contributing to this issue seems like a "deny service card" and a bit of distraction from a known defect.  My vehicle has been pampered with ~5000mile OCI's since new with the recommended oil.   I do understand how the vacuum pump is lubricated with engine oil.

 

Vehicle is a 2015 Suburban LTZ with ~51,000miles.

    • So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.
    • My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.
    • Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?
    • I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions. 
    • I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
