wacko

I remember similar issue with mine when new. Opened all vents (to far up or down up front restricts flow and to far left or right in rear console vents restricts flow). No issue since adjusting. Current generation System appears to move more air and vent restriction can cause noise for sure.

The only other option to make the NHT perfect is the Brembo Brake set up... I have only had a few emergency stop situations and they are impressive

I have a 2019 6.5’ bed, CC, 6.2, NHT (3.42 rear end). Drove Cincinnati to Charlotte and back: upper 70 mph range always run 93 octane from Walmart/ Sam’s truck is getting close to 20k miles truck seems to finally start getting good mileage after 10k on the odometer. autostarts kill the number as well.

2019 Sierra SLT headlights are nearly perfect and when people “squeeze in front of me” they are even better because they are mounted high enough to hit that side mirror on the offending driver perfectly. fogs are good and do a decent job. taillights on models with LED are a good combination as well. Good intensity but not over the top.

That doesn’t look like a T1 slider though...

The fuse is in the passenger side fuse box. It can be installed for constant power or switched. I have a heated air freshener and it works perfectly switched

I had the problem and it was all directly related to a bad software build. The problem was corrected and have used the remote and app for auto starts and haven’t had a single issue. The problem was corrected.

The rear end ratio is different as well on The Heavy Tow loaner as well. I was scared to get an NHT truck because of the ride but I find it a huge improvement over my 14 All Terrain and both have 20” wheels. The loaded ride is superb and very stable.

The one thing that surprises me most on the T1 interior is how flimsy the dash panel is where the seat heater/cooler buttons are. The K2 buttons mounted area was extremely rigid. The T1 interior panel moves when you push the seat heaters. Other than that the interior is top notch and very user friendly

Hot spot to your phone works for weather app FYI

I had the update done yesterday. After a day of driving and multiple auto-starts with app and fob: All is well (so far). I was in a loaner for a week and it’s nice to be back in my truck. This software build initially appears pretty stable.

The 10-speed is an excellent transmission. A Friend of mine has a platinum Eco-Boost with the 10-speed that we have driven numerous times on a 10 hour trip. When I got my 19 with the 6.2 and the NHT gearing I couldn’t believe the difference and improvement. I believe with the 5.3 it is an even bigger improvement. I have yet to feel a single questionable shift. Only thing I would like is an Eco mode option in the shifting profiles with Sport and tow/haul.

Have a 2020 Sierra SLT 5.3 10-speed loaner and it is a very good combo. Haven’t had any shifting issues

Just got a call from dealer that my truck is FUBAR until the next software is released. They will not give me the truck back because my ABS is currently comprised. I am in a loaner for 2-more weeks. I would advise anyone with appointments to get anything software related done, to wait.

Maybe they are giving you Kilometers? 18,500 Miles is 29,772 Kilometers
