It reprograms the hydronic system to add more pressure and make up the difference at low speeds. Never had an issue with my brakes until they got ahold of it. How long after the flash did your pump go out? Do you think there’s any connection between the 2? 

I can't seem to find when the vacuum pump was replaced but found that the flash was done in Oct of 2019 as part of a nationwide recall. Before that, no brake problems. It seems like it was within a year I had to have the vacuum pump replaced. Are they related? Most likely. But did the flash cause the issue? I doubt it. There was a problem that GM was aware of which resulted in the mandated recall. IMHO  GM cheaped out and just tried to "fix" the problem by doing it the least expensive way they could with the software flash.

I have a 2017 1500 LT, similar issue (just the infotainment system). I saw a YouTube video about tightening a wire connection behind the glove box. That fixed the issue for about 30 days. I am now looking at a replacement aftermarket system. It is very frustrating when using GPS and the map just randomly moves 100 miles in any direction while at a stop light.

2018 Silverado owner here.   My screen will change the view and my

MPH reading will go into song names on its own.  Also it my phones plugged in and this is happening (not daily yet) it will mute my call I’m on off and on every 2-3 seconds.  Also my AC is not blowing any cool air.   Just out door air.

Same issue here. Very frustrating. Hate just throwing money at it. Seems to come and go and I considered an aftermarket unit but I was hoping there was a definitive fix.

    • It took me a minute, but I got it.😆
    • I have A 2020 1500 5.3 8 speed. LTZ. Transmission problems since 60,000 miles. Started when I go to store in morning to get my morning coffee before work leave truck running get back in put it in drive/ rev no movement step on gas a little slams into gear. Put in neutral step on gas little shake then put in gear and gose.  Shut truck off start .. ok now at stop light stop truck after a few seconds feel a little kick if that doesn’t happen stuck in 3/4 gear shut truck off wait few seconds and start usually ok again. If you down shift manually ok as long as you get into 1st before stop. If not it kicks . I WANT A NEW TRANSMISSION. Now I want a new truck it just hit 80,000 IDK IF ILL BUY CHEVY CAUSE THEY STILL HAVE THE PROBLEM AND REFUSE TO RECALL . Oh I’ve changed the fluid and filter 3 times now. And yes used mobile 1 not ac/delco cause it’s not meeting the requirements that mobile is did use ac/delco filter 
    • Of course refrain from political debate but I myself have very dismal hope for what is all going on up here every where we turn so I nodded my head when I saw this joke.     
    • I'm looking at carpal tunnel surgery on my left hand and lumbar fusion. 
    • While waiting for parts I have been working on installing the AC compressor, new accumulator, and orifice tube. Also changed out the high side ball valve (original). The orifice tube that was in there wasn't too bad. Slightly dirty, a little bit of junk, but not blocked. Glad I changed it out.   The accumulator, which should have been a 5 minute job, may have just burned $50. Put some PAG in it, wrote the date and mileage on the side, fresh o-rings and gooey'd up the threads and rings with Nylog. Got everything connected and snugged and was going to vacuum down the system, and....   My manifold gauge won't fit on the port. It's not an R12 service port. It LOOKS like an R134 service port but the diameter is a hair too large. There's a sticker on the accumulator that says it's designed to be used with R12 and R134a systems only. So it's not R1234yf. Even if I reduced the diameter slightly with a file, the shoulder on the port is too large so the quick-connect valve won't lock on. I'm stumped. It's going back, and 50/50 on if they'll give me a refund.   Also, I did a fuel pressure test.... Key on, the gauge spikes to about 60psi and quickly bleeds off, like 2psi per second. The fuel isn't going into the plenum, no smell, starts fine, so I'm guessing there's a bad check valve in the pump and the fuel is just draining back into the tank. oh, hell. But, it shouldn't be a problem, pump primes just fine and the truck starts right up. It just means I can't really ever use fuel pressure to verify a leak at the injector or intake.
