I don't try to hypermile my 4.3L V6, and we have a lot of hills around where I live. My highway best so far is 25MPG averaging 70mph, but I've never been able to duplicate that. My combined average is between 18-19 with winter fuel, cold mornings and pre-conditioning. Combined average 20-21 in the summer. I'm a little disappointed as I figured the little V6 would do better, but maybe it's working harder. I find the DIC is pretty accurate, usually about 0.2 mpg optimistic.
The only quirk I've encountered was I had to "reset" the infotainment system by pulling the fuse. Other than that it's been reliable. The only major annoyance is the transmission (6sp) banging and clunking under light throttle and coasting.
I haven't owned many recent iterations of GM's full size truck, but have had plenty of their cars over the years, and they all suffered from buggy software, specifically transmission programming and Infotainment systems. Of all the issues, these have been common on all GM vehicles I've owned for the past 10 years. Frustrating that GM can't seem to figure these out. Although it sounds like they've got the transmission programming worked out with the 10-speed Mechanically, however, I have had no major issues with any of them. They may not have been the most refined, or the quietest running, or the most fuel efficient, but they weren't the most expensive either, and always started when I turned the key. Now if only GM could fix their software bugs...
If you succeed in removing the resonators, let me know how it sounds with just the Super 10. I'd also like to give my little V6 a little more growl. I don't expect a V8 sound, but I haven't heard anything yet that doesn't sound like a buzz bomb at higher RPM.
Just posted about this in another thread. My 2019 Custom has 4700 miles, this just happened to me last week. Shutting off/restarting the truck didn't work, turning Auto headlamps off & on didn't work, the only thing that worked was reseating fuse F41. I have an oil change coming up and I'll ask about software updates, although I don't think there are any available yet.
Amen to that! Also annoying are the drops on the camera lens when it rains, makes it almost impossible to see anything via the RV camera. Plus not being able to reduce the display brightness at night when the camera is active.
Well, the Infotainment 1 fuse pull procedure works like a charm. I just hope it doesn't happen very often as I don't want to wear out or break the trim piece or plastic clips by removing/replacing the fuse panel cover multiple times. Really wish GM's programmers would get their act together and fix old bugs before introducing new ones.
Well, today I lost all phone connectivity again, but this time the screen went blank. The volume control still works but I cannot use any other functions. The backup camera displays when I put it in reverse, but nothing else does. If I shut the truck off and open the door, the display will appear for a split second then fade out. The "reboot" procedure doesn't restore it to normal, so I'm going to try the fuse pull method. You would think after all these years they could fix their stupid bugs, but apparently it's not a big enough problem for them to put much effort into it.
Really just a rant, as I figure there's no fix for this... I have experience with the buggy center stack/infotainment system in my 2014 Volt. Today I experienced my first bug with my 2019 Silverado Custom with the base IOR system. I had the iPhone plugged in, using nav via Car Play. Suddenly the system decided to drop both the Car Play and the Bluetooth connections, Car Play closes and the icon turns grey, and I couldn't reconnect the phone to the system at all. Neither USB nor Bluetooth worked. Whenever the system would crash on the Volt, if it didn't reboot itself (which it would sometimes do while driving), I would have to "reboot the car" by parking, shutting the car off, getting out, locking the doors, unlocking the doors, getting back in and starting it back up, after which everything would work again. Lo and behold, I did this with the truck, and everything started working again. Nice to know the same old GM software bugs are alive and well in 2019... Is there a way to do the truck version of Ctrl-Alt-Del without having to perform the Chinese fire drill?
Black is the sharpest color for a Silverado Custom. I looked at other colors and none looked as sharp as black. Black is beautiful. When it's clean... But trucks aren't supposed to be clean (at least that's what I keep telling myself?). After the first couple of months I don't mind anymore when it gets dirty. It makes me think it's being used the way it's supposed to be used. I just wash it once a week whether it needs it or not (and it always needs it). My next truck will be a higher trim model, and will NOT be black.
Maybe GM can save us from ourselves by adding the power-lift option to the MPT and adding a proximity sensor that will detect any obstruction, such as a hitch, and halt the tailgate from opening any further? Modern vehicles have all kinds of nanny doodads to protect us from our inattentiveness, so something like this shouldn't be difficult. Sure beats removing the hitch. I do agree that providing the ability to lock the load stop in the extended position would be a no-brainer. That omission was just ridiculous.
I just got used to keeping it on me holstered. If I'm going where I know I cannot carry (like work) I usually leave it home, otherwise lock it in a secured under-seat vault, but if I'm carrying it stays on my person even in the vehicle.
^^ Ditto this. Also, what does the dealer need in order to program the unit? I ran across an issue with the Trailering Hookup Assist app where GM wouldn't provide the unlock code for the dealer to install it, because my truck didn't originally come with the option (which was the whole point of having the dealer install it!). I don't want to spend hundreds of $ just to hit a brick wall when it comes to programming.
