Update 10/5: See below post. TDLR- I'm sick and won't be able to attend this drive.

We are excited to announce our next Live Post First Drive. On October 6th we will step behind the wheel of the refreshed 2016 GMC Sierra and all new 2016 2.8L Duramax Canyon.

We can't wait to share our experience driving of these exciting new GMC models as it happens. If you've never seen one of our Live Posts, check out what we've done in the past.

In the meantime, we're looking for your suggestions and comments. What do you want to know? What do you want us to check out? Even highly technical questions are welcome as we will have an opportunity to chat with engineers and product managers.

See you all LIVE on October 6th!

MPG loop on the Dmax. I have yet to see any official EPA ratings but I may not have tried looking to hard yet. Oh and how it tows as well. The exhaust brake on the big brother HD was/is the best one on the market so hopefully some HD tech was applied to the twins.


Oh and interior noise level. Cruze diesel is great but was a bit noisy when pushed in the higher revs inside.

I'd like to see a comparison between the 2.8 L and the 3.6 L in the Canyon regarding: emissions; handling; cold weather performance, issues and concerns; anticipated annual cost of ownership over 5 and 8 years; and anything else that you can think of that isn't normally covered in the typical test or review.

I live in northern Alberta, Canada and see the Canyon as my next truck once I mile out my 2010 Sierra. Initially, I was planning on buying the 3.6 L but I am being open minded and want to consider the 2.8 as well. But, I want my decision based on sound knowledge and not live to regret deciding on one over the other.

Thanks in advance for for any and all info.

I saw the specs some where. It said it would tow 7500 lbs properly equipped. so what is "properly equipped" and will that be factory available?

Also, would it be safe for a truck this size to be towing this much weight?

if I were to tow a travel trailer with a high profile, how would it perform?


I currently own a 2008 silverado LT with a 5.3L engine and a standard bed. I tow a 5200 lb 24 foot travel trailer with tandem axles. Personally I would not want to tow a bigger trailer with my current set up and the panel on the truck rates it at 7700lbs. I am set up with all the proper gear, sway control bar, heavy duty Reese platform, load levelers.

Mountain towing. Can it maintain 70mph while towing the mfr maximum towing weight up a 12% incline for 7 miles (I77 going North in to Virginia)? How's it handle coming back down the same? Heat build up while doing so? How does the A/C handle 99 degrees with 95% humidity at the same time? Noise levels per the Cruze comment earlier? 4x4 Low range throttle response off idle, will there be an alternate throttle curve for low speed off road driving?

Clunky drive train?

Slippy gears/converter clutch?


Accelerate up to 30km/h and slow down rapidly. Repeat 3 times. Like in stop and go traffic. How is the trans shifting?


Hover with the gas pedal at a shifting point of the transmission. Is it shifting up or down nicely?

(What I mean is my truck shifts at 35km/h from 3rd to 4th under slow acceleration. When I just barely accelerate the shift is clunky and rocky).


Down shift on an incline. Does the engine rev up and is the converter clutch slipping like you're riding a clutch?


I hope you understand my questions. Sometimes it's hard to explain.



so long

Very curious about throttle response. Does it respond well to rolling into the throttle? Shift quality is also important.


My 2012 5.3 Sierra makes decent power if WOT but has lethargic throttle response and shifts are all over the place. Some are smooth, some are firm but other times I get slow shifts with flare.


Hoping they improved this on the new trucks.


And obviously fuel economy numbers.

How about GM publish a salt-spray test, so that we can gauge whether or not the thing is going to become a rusted out, useless, $40k paperweight in 8 years like their full sized models? I won't be holding my breath on that one ...


A lot of good a diesel is when the body can barely make it past 200k ....

Hi everyone. I'm pretty sick today and won't be making this drive. Thankfully I have a chance to drive these trucks next week. I will update you all on the new schedule.

      I have a 2022 Silverado 1500 four-wheel-drive. The dealer ordered the 2 inch lift kit they offer and I’m waiting for it to come in and have it installed. But I noticed that the kit doesn’t come with upper control arms. Is that going to be a problem?
      (***UPDATE*** )
      so I had the factory lift gm offers installed. When I picked it up, it looked great but as soon as I went to drive it off the lot. I could tell something was wrong it felt completely different. I figured it was just a break in period. But even after a day or two, I was getting crazy bad vibration at low speeds. Took it back. They ended up putting one of the U-bolts on wrong (I have pictures if wanted) they fix that and told me the vibration was gone. I get my keys go to drive away vibrations right back. I turn right back around. this time they have a mechanic ride with me. He clearly hears  an feels a vibration, says somethings wrong so we turned around and he takes it back in. Three hours later they bring my truck back they had to remove the back blocks said there was no taper to them and it was messing up drive line. I got it back and the vibration is still there. (Now annoyed that only the front is lifted and still vibrating). I have them take the whole lift kit off. Put it back to stock. (Now remind you my truck has been down and I’m missing work for 5 days at this point) And after that Whole ordeal, I was done with the truck since I couldn’t have it how I wanted it and decided to trade it in and they made me a good deal on a 2023 5.3 LT.z71
      I know many have gotten this lift installed said it worked out for some reason it did not for me. I’m much happier with the new truck.

      Has anyone found a blanket that fits the lm2 turbo or modified one to fit?
      Amazon has some inexpensive blankets for other turbos I wouldn't be against modifying.

      I have a 2022 trail boss lt that has about 6100 mile on it now. Bought it brand new in may 2022 and it seems like the drivers seat leans to the left towards the door. Almost feels like Im gonna fall out of it and no matter how I adjust it it seems the same. Visually it looks like it sits level and is fine. Is it possible something is broken inside like the frame? I would assume the frame would have to be sturdy. Is there any place that sell a better bottom cushion?

      Hey all,
      I have a 2022 Sierra SLT with passive entry locks on the front handles. Does anyone know if I can easily add passive entry locks to the rear handles? Acquiring the actual handles would not be the issue but I'm wondering if there is a harness (or whatever powers the front passive entry buttons) in the rear door to begin with. I know they come standard on Denali, so was thinking GM might just leave the wiring in the door for different trims but not include the passive handles all around. As I type this, though, I'm sure there's programming that needs to be done but figured it was worth a shot - because why not!
      Any help is appreciated, thanks!

      or sale are my set of custom painted, OEM Sierra Denali LED Tail Lights. I had these painted to go on my truck and unfortunately they took so long I had to go a different direction before I got them back.. I have since moved up to a 3/4 diesel and am hoping these can find an owner who will appreciate the time, effort, and $$$ that went into creating them!
      These OEM LED Tail Lights are selling for $300 - $500 a piece online, and the cost to have these custom painted Mineral Metallic to match the Denali paint + the lens smoked (lightly, not enough to dim them when lit!) was $700 - looking to get $1,000 including shipping. Can cut a better deal if wanting to pick up in person in the Houston, TX area.
      Please reach out for additional pictures, questions, etc. I respond much quicker via text (405) 642-9097
