    2019 Sierra 6.2 AT4
  1. Real world city MPG?

    6.2 400 mile - without trying to conserve fuel.
  2. Best tonneau and why?

    You may want to look at the Fold-A-Cover G4 elite. It has the best locking latch system I've seen on a folding cover, and you can't open it with a coat hanger or Slim Jim like the Undercover or Bak.
  3. Speed governer on 19's?

    The shutoff is based on the speed ratings of the original tires. My AT4 with the Q rated LT275/65R18 Duratracs shuts off at 98 mph.
  4. Since no auxiliary/replacement tanks are ever likely to be available, I was thinking about going this route....http://titanfueltanks.com/titan-sidekick-15-gal-portable-liquid-tank-5040015
  5. Mine makes a whirring noise that sounds a lot like the servo motors on a robotic arm. To tell if the sound is the parking brake, stand outside the vehicle by the rear wheels while someone engages and disengages the parking brake. You'll hear the the parking brake motors on the rear axle. Since my driveway is sloped, the brake motors will engage automatically when I park.
  6. No software update I know of will fix that. It looks like either a connection issue (cable or board) or a bad display. I see similar issues when cables get pinched too.
  7. Here are 2 from the T1 Exhaust thread in 2019 Silverado & Sierra Mods
  8. When they do get it working just ask them to give you a free month. it's the least they could do. I'm beginning to think that OnStar is not up to speed with the new Infotainment systems. It took them a week to solve my issues with live traffic. On a side note - Iv'e had my truck since October and my insurance company (AAA) still can't verify my VIN number. Which is funny because the state already issued plates and the VIN is in their system.
  9. Costco's Annual Auto Sales Event Underway

    FYI - you don't have to go thru Costco to to use the promotion. I didn't know about the promotion when I bought my truck but the dealer did. They took my card and entered the info for me. The next day I received and email with the authorization number and a link to the survey. 4 weeks later I received the cash card.
  10. Unfortunately, you are correct! No $3.99 Navtraffic for the 2019 upper trim levels. For real-time traffic you need Connected Navigation, which is only available with the $39.99 GMC Unlimited Access plan. Since it's a new Infotainment system, the OnStar reps seem to be unaware that Navtraffic is unavailable on the new systems. it took an hour on the phone with OnStar to get the unlimited access plan added back into to my system and another 16 hours before it was fully integrated.
  11. Yes, been there done that. When I open my account there is no Navtraffic or Travel link option available like I had with my previous truck. XM claims that my radio is not capable of using the plans.
  12. Just got back from the dealer and they were absolutely no help. Dealer says that I should be able to get Navtraffic through XM, and it's XM who does the upgrade not them. So now, it's back to OnStar. Does anyone with a 2019 have XM Navtraffic? or is the only choice for live traffic the $40.00 a month Onstar package? I know I could just use Android auto, but most of the time I just need to hop in the truck jump on the freeway, and it would be nice to see the traffic conditions before i got on the onramp. On Edit: I have both an Onstar account and a SiriusXM account for the truck.
  13. Hopefully someone has dealt with this on their 2019 already. I received the attached notification on my Nav screen. I pressed the advisor button and asked OnStar what was needed to maintain real-time traffic. OnStar said it was only available from Sirius XM. To which I replied, “it wasn’t available when I signed up for XM radio” (I had it on my previous truck). The advisor checked and said Navtraffic was only available from XM and transferred me to the XM rep. Who said that my radio isn’t set up for their Navtraffic and that I needed to go to the dealer and have it programmed for Navtraffic? I replied, “Then how come I have traffic displayed on my screen right now?” the XM rep didn’t know and couldn’t help. 3 days later and traffic data no longer shows up on my Nav map. Which to me means it’s handled through OnStar and is only available with their unlimited access plan for $40.00 a month. I currently have the Safety and Security plan. I guess my question is – does any still have real-time traffic after their free month expired? and if so, which company are you getting it from?
  14. T1 Exhaust

    Appreciate the update! Just placed an order and it'll be here in a week.
