Thanks I'll check those

I thought the same thing, checked all the fuses in the engine compartment, but none of them were blown. I'm guessing this fuse may be in another location. Hoping someone will chime in and maybe know that information.

I have a 2014 Sierra Denali and my 110v charging port has stopped working. The little green LED never comes on. I first noticed this with my phone charger, it's for a Nexus 6 with the Qualcomm QuickCharge 2.0 technology. I know this outlet is only rated for 150 watts, but this charger is far less than that. I also tried my Macbook pro charger, rated at 95 watts, and the port still won't work. Anyone else run into this problem? I'm thinking I have a major problem with all my power ports, 12v chargers included. The reason being my KDLinks X1 dashcam keeps going to an all white LCD screen while driving. It just started doing this a couple months ago and never did it before. When I try it on my Dad's 2013 Malibu, it never resets to the white LCD screen. So basic trial and error leads me to believe it's something with my Denali's power ports. Just wanted to check in with everyone here on the forum, as I plan on making a service appointment to get this looked at. But as we all know, they'll probably say NOTHING is wrong with anything, as usual. If I could get some feedback here, at least I can guide the EXPERTS in the right direction on how to fix this problem. Thanks so much!

No problem, glad I could help.

Haha, I did the EXACT same thing! Size 15 boots took it to town! Just happened to me a few weeks ago. Same piece, same color too! Here's the part number you need: GM# 23427386 Got mine from GM Parts Center http://www.gmpartscenter.net/oe-gm/23427386 Paid $20.66 shipped Hope this helps, easy to replace. Just move the driver seat all the way up and lift it to the max settings and you'll be good to go.

100% agree! My Denali has NAV and I absolutely hate it! It sucks, plain and simple. The voice recognition software GM uses is a joke! I cannot tell you how many times I tried using it and was cussing up a storm. I stick with Google Maps on my Nexus 6 over bluetooth. It works and Google has the absolute best voice recognition software in the world, IMO

Anyone know the GM Part Number for an OEM windshield for my 2014 Sierra Denali? I unfortunately got a humongous rock chip on the freeway and it's driving me nuts! I got it filled and it still looks bad. Just trying to get a price for it, compared to what my deductible is. Thanks EDIT* I believe I've found the GM Part Number, it's # 23129272 http://www.gmpartscenter.net/gmc/sierra-1500/23129276/2014-year/denali-trim/6-2l-v8-gas-engine/body-cat/glass-windshield-scat/?part_name=windshield Can someone confirm this for me? Find it HARD to believe it's only $254 for a windshield, I was expecting somewhere in the neighborhood of $800-900

Thanks for the info Tim. I haven't gotten an exhaust yet, so your input is appreciated. I was thinking the same thing, based off the clips online, but that's hard to tell unless you hear them both in person. The drone is my big issue. It's nice to know the Corsa sounds better. Did you go with the straight back double exit or the single exit on the passenger side? I was leaning towards the single exit, but I know those chrome tips will get thrashed by road debris and rocks.

How fast do you drive? I took my Denali to San Diego and back, put about a 1K miles on it and averaged 20.6 MPGs the entire trip. I kept the cruise right around 73-74 mph the entire trip. And this did include spurts of L.A. traffic.

Just logged a quick trip yesterday with my Sierra Denali (6.2L), 91 octane, got my best mileage to date:

The thing that confuses me is this whole flapper valve issue. I believe someone mentioned it is for the V4 mode, to prevent drone. Does anyone out there with a 6.2L and non-OEM Borla exhaust notice a major drone issue with V4 mode? I'm still leaning towards the Corsa system, but I really really do not want drone, it would be a major issue for me.

Oh ok, I kinda figured that, I just wish it'd be more precise, like 30-20-10 LOW could mean any of those Damn, I've never towed before, but man is that a low MPG number. That trip had to cost around $800 in fuel

Thanks for the reply. If I could be confident I can get 500 miles out of a tank, I'd rest easier. It just seems the low fuel warning light is coming on too soon. Time will tell.

Question for those with the Denali gauge cluster...... Since ours is a digital gas gauge, are you finding the low fuel warning is coming on prematurely? As shown in my post above, I averaged 20.8 MPG coming back from San Diego and the low fuel light came on when I was approximately 10 miles from my house. I searched through the Denali manual, but didn't see anything stating how much fuel is left when the low fuel warning light comes on. I heard someone mention 2 gallons, which at my MPG level, would mean I had nearly 42 miles of range left. When the light first came on, it did state a range of 56 miles, then gradually went down, until it just stated fuel range "low". How it went from 42 mile range to low is beyond me. What is low supposed to mean? 5 miles? 10 miles? So here I am coasting to my driveway thinking I could run out of gas at any second and long story short, I put gas the next day and it only takes 23.XX gallons So that tells me I had 2 gallons and change in my tank. Here I was thinking I would run out. The reason this is such a big deal to me is because I will be making this roundtrip to San Diego quite often in the near future and it is exactly 458 miles door to door for me (and I HATE HATE HATE to stop on road trips, literally will not stop if I'm by myself). Simple math tells us a 26 gallon tank @ at least 20 MPG (which I averaged to and from) should net me a range of 520 miles. Yet as shown above, my trip meter read 465 miles on the return trip with the low fuel level warning triggering and the range stating just "LOW". So am I to believe I still had a range of 55 miles even when the fuel range stated low? Based on the exact math, that's what the range should have been.

Hello everyone, Just got back from a trip to San Diego, put about 1000 miles on my Sierra Denali with the 6.2L Please keep in mind I live in Commifornia and we have the strictest emissions in probably the world. Please also keep in mind I was 1 of 4 people in the truck with an estimated payload of 1,000-1,200 lbs (4 bodies plus various suitcases, laptops, coolers, etc) Also, this trip occurred in 100* central valley heat for 62% of the miles Truck is 2WD with Standard Box Used 91 octane entire trip Here are my real world MPGs with my 6.2L (truck is basically brand new, picked up in 2nd week of April, this was first road trip): To San Diego: From San Diego: I was extremely pleased with the 6.2L getting over 20 MPGs on a trip like this. When you account for the CA emissions restrictions on my truck, the valley heat, the payload, the L.A. traffic and the Grapevine (mountain range separating NorCal and SoCal)..... to get 20.8 MPGs on my return trip is outstanding IMO. I kept the cruise control on 73 MPH on pretty much the entire trip (when I wasn't in traffic). So count me as very impressed with these new engines from GM. I NEVER came close to these MPGs in my old 2010 GMC Sierra CCSB with the 5.3L
