I had this posted on Troubleshooting..probably should have posted it here instead...Friday update..Dealer is taking it in on Monday...brake wear indicator is now at 36% after only 300 more miles driving..BUT the brakes feel uneven ..occasionally quick boost then next stop major effort required..don't like that... Here was my post: My 6.2 Z71 Silverado has been having ongoing issues with this pathetic entertainment system .. 1st - the infotainment screen , new for 2019 models , has a much thinner and lighter typeface then the 2018 unit..makes it very hard to read secondary information displayed.. The older unit had secondary info in a dark teal color..stood out very well..this one is gray. I showed the difference in an earlier post. The typeface on the controls is also smaller and thinner and lighter. 2nd. My truck showed a service power brake boost on the DIC.. actually eliminated all power assist on the brake system. The dealer receipt showed a few downloads software updates and the message has not shown up again. HOWEVER with only 7000 miles the brake life monitor is showing 44% . The monitor was showing 85 % at 5000 miles when the updates were applied at the dealer. The truck feels like it has minimal boost , then no boost, then it feels like the pedal is being pushed way too far to stop. Something is not right.. Oh and my mileage is 90 % - Interstate 75 between Ft Myers , Fl and Tampa, Fl . 3rd problem . on the entertainment display, when I took her in for service at 5000 miles, the unit said climate control off.... it would recirculate air but no fan speed or coolness.. I was told there was no fix at that time. Its been 5 weeks and it has happened 10 more times..and it is a 95 degree Florida summer. 4th problem, The display says service rear vision camera. there is no back up, no surround, no nothing..this has happened 6 times now..As in all the problems except the brakes, , it appears normal after 30 mins and a restart. My 2018 Colorado had NONE of these issues... My dealer is 30 miles away, My neighbor has a 2019 Denali 6.2 and has had none of these issues..he is at 14,000 miles and his brake monitor is at 86%. His brakes also feel like mine did before the downloads....Like they could actually stop the vehicle. Now it seems that there is a big issue with this whole entertainment computer system. I would rather have a lower HD display and systems that worked than them selling me a 68,000.00 truck that is not ready for market. Judging from the posts on this site, there are many experiencing these problems also.... My Uncle has a 2018 Escalade..6.2 10 speed..he has no issue with the electronis or the display..They had surround view for a few years. He also has 36,000 miles on it and has 58% brake life left. Sorry for rambling, but I was ready to buy a 2019 Camaro 2ss, But no more new system... If they can't fix it then they need to stop selling it. GM must have hired the Boeing Software Engineers.. Take these problems away, and it is a creat truck, powerful, good looks, But ya gotta have the whole thing working at this or any price point... Thanks for viewing my ramble.

I have a high pitched whistling sound when ac is on..turns out it is the left driver upper ac vent...This was on mine ..but I found it...

Mine had all recall and software updates supposedly taken care of last week..6600 miles and screen says....service rear vision system ... which stops all camera assist including all around and front cameras.

I have a strange one ...a whistling sound coming from the drivers side area... I thought Mirror air whistling ..nope..I thought under hood ..nope..I thought Badges on side ..nope...I turned off the ac ..almost a never situation in SW Fl... and the noise stopped..turned ac on and back it came ..turns out it is the upper console drivers ac vent whistles with higher speed... crazy...

Dealer checked code and the response was that GM was aware of the problem and was working on a fix.

I had the brake message and software refresh, but now I have to exert greater effort to slow and stop truck... definitely eliminated the message but now not a good brake feel. 6600 miles..

6600 Miles..mine just turned blue today and my screen still has the occasional climate control off screen... That is 3 electronic bugs ...We should get an extended warranty of 6 months to allow for our troubleshooting GM's bugs!

I also am experiencing a high pitch noise almost a whistling sound...it is not there when I am below 20 mph but shows up afterwards, I can eliminate it by turning up the bose. I put down the windows and it almost sounds like it is a wind noise coming from the drivers side mirror assembly. I may try to tape a few openings to see if it gets reduced....I just read the service info from above...will ask the dealer at 1st visit. Thanks for the info...

I have to make approx 20 stops a day ...My 6.2 shutters each time it restarts, very annoying.
