  1. Appreciate all the great info on the thread. There’s another thread on this with a similar title and people are mentioning a DEF system recall, a program update and one person had to have their exhaust repaired which was causing over usage. Search DEF on 2020 forum for more info. Nate Sent from my iPhone using Tapatalk
  2. Thank you. I was factoring each bar was a half gallon and added up all the bars. Appreciate you pointing it out in the manual. Sent from my iPhone using Tapatalk
  3. I posted a thread on this a few weeks back. I’m getting 300-400 per gallon towing 9k lbs trailer. My sensor misreads all the time. Just filled up and it shows half empty still. About 500 miles into a 2,500 mile trip over the next 5 days. Hoping I don’t end up in throttle mode limping down the highway because this sensor is off. Any way to reset the sensor?

  4. Thanks for the reply, that kind of mileage is in-line with what I expected not towing. I have a 2020 with the L5P mated to the Allison 10 speed. I thought it was 7 gallons too but the manual says 5 gallons for my truck and when it’s down to one bar, I can only add back 4.5 gallons. Have you been able to put more than 5 in yours?

  5. I know our tanks hold 5 gallons of DEF fluid. I seem to burn through a gallon about ever 300-400 miles when towing. Makes sense that it would burn faster while towing. Dealership said I should be getting closer to 1k miles per gallon on DEF. Even when I’m not towing, I’ve not seen anywhere near that number. Anyone else been tracking how many miles per gallon they burn? Towing/not towing? I don’t mind the cost of the DEF, just want to make sure I don’t get caught out in the dessert or mountains on crawl mode. I get pretty remote at times. I carry a couple boxes in the truck for long hauls. It’s also way cheaper if you fill up at truck stops versus buying Blue DEF online or at stores. Sent from my iPhone using Tapatalk
  6. I climb a 6% grade everyday for work and it’s about a 15 mile round trip at 12.5 MPG no load. I have also towed a 9k lbs trailer for about half the 9k miles on my truck. I’m averaging 13 MPG over those 9k miles. If I’m driving with no inclines and on highway without a load, I can get 24 MPG. Mixed highway and city flat surfaces 19 MPG.

  7. Leave your truck in park and navigate to the options menu in your settings. There you can add or delete what shows up when you toggle through. See if it is somehow unchecked now. Sent from my iPhone using Tapatalk
  8. I did not have an issue the first 5k miles on the truck. The last 3k miles this has happened a handful of times. Those miles all came in the last few weeks on a long trip pulling my trailer. Sucked not having my Sirius XM, Spotify or WiFi periodically for the wife and kids. Especially, since I pay a lot extra per month for all that ******. I was wondering if it’s the satellite fin on the roof or if it’s software. To the person that took the fuse in and out, you’ve not had an issue since? How long has it been? Thanks, Nate Sent from my iPhone using Tapatalk
  9. #1 is a software update. #2 they remove the heat shield. Detail on removal below. https://static.nhtsa.gov/odi/tsbs/2020/MC-10172662-9999.pdf Sent from my iPhone using Tapatalk
  10. Just dropped the truck off for its first service at 5k miles and there are two service bulletins. Oddly, neither of them show up in my OnStar monthly report or MyGMC app even though they’re dated as released Feb 2020. I already had a seatbelt issue fixed a few months back as a recall. Here’s the two new ones: 1. Service Update Bulletin (N192285430): Engine Control Module Calibration Error 2. Service Update Bulletin (N192286190): Fuel Leak Due to Accelerated Corrosion Sent from my iPhone using Tapatalk
  11. Yeah. Your truck should have come with the sensors. Mine were under the back seat. It should also be wired up and ready to connect to those sensors. Sent from my iPhone using Tapatalk
  12. I want your garage! My 2020 AT4 HD doesn’t fit on the garage. My 35’ TT sits outside too. Would love to have indoor storage but here in So Cal that’s about $600 a month for the travel trailer. Sent from my iPhone using Tapatalk
  13. Between the strike in Flint and now this for the next few months, I’d be interested to see how many 2020 HDs are produced versus a typical year. Sent from my iPhone using Tapatalk
  14. I’m waiting for a 2-3” kit from BDS and will replace with their fox shocks. Put some 35s or 37s on the truck too. My last truck had fox shocks that were much better than factory. That had a 6” lift. Don’t want to go that big because I’m planning to go from a bumper tow to a 5th wheel. Will see if that takes care of the sound. Sent from my iPhone using Tapatalk
