  1. Has anyone had a rear compressor issue with a new Yukon XL Denali? My wife and I bought the vehicle at the beginning of October 2018 and within a month the rear compressor began running excessively. We took it into the dealership with bought it from and the service rep heard the noise but was unable to reproduce it later in the day with the technician so they sent us away with the vehicle. The noise became more and more regular so we took it to a dealership near our house and they heard it and acknowledged the problem, this lead them to replacing the rear compressor. The change of the rear compressor didn't do the trick and the excessive running persisted, this is where the frustration really set in. The service technicians were going to run diagnostics and service the vehicle after we brought it in MLK Day. The service department manager interrupted the process and essentially tried to bully my wife into accepting the fact that this is normal behavior for a GMC Denali line vehicle. She left the dealership in tears. I called the service manager in disagreement with 1) his treatment of my wife and 2) disputing the fact this is normal. His response was the discharge the video with a bogus report emphasize the vehicle was in intended working condition. Now the Denali is sitting at another dealership while they try to replicate the issue. It occurs 30-40% of the trips we take in the vehicle and the rear compressor will run anywhere from a few seconds to 20 minutes. Has anyone else had this issue and found a resolution? I'm to the point I'm almost willing to just sell the vehicle back for a loss to be rid of it.
  2. It's never too early to start talking about the process of shopping around for a dealer, pricing, the ordering process, deposits, and production delivery times. Although we're still months away from orders being accepted, this thread is meant to be a place where everyone can check in and share their experiences as they go through the process. I'm also going to document as many important dates in this initial post as I can. I'll attempt to keep everyone up to date on start of production, any ordering limitations, and when the ordering system will go live.

  3. Anyone else with a new 2014 Sierra having an issue with the frame rusting and paint/wax flaking off? I have 3000 kms and it looks horrible. I also own a 2011 Canyon service truck with 105kms and the frame looks like new. So irriating as my Sierra is a beautiful truck aside
  4. I'm interested in a quick read of the room. How does everyone feel about the news that GM is moving in the direction of an battery electric truck? Does the brand it's sold under influence if you'd be interested? Are you ready to buy one now or do you think we should wait it out? Thanks for your opinions!
  5. I recently bought a used 2016 Sierra Denali 5.3L 4x4 in March with 48k miles. Truck has been great until yesterday (now 52k miles) when I ease into the gas it shudders and shakes like crazy until i punch it. The tach is bouncing up and down and it doesn't matter if it's in v8 or v4. It almost feels like it's a misfire but it's weird that it only does it when I'm easing into the throttle or going uphill. The truck has the 8 speed transmission. Has anyone else ran into something like this and would the manufacturer warranty cover the fix for this?
  6. Hey everyone! Welcome to this Tonneau Cover thread. Looking to purchase another Tonneau Cover for my 2018 Sierra 2500HD. I know there are a few sites but wondering where you guys have purchased in the past and where to find the best deals? I've been hearing that http://www.TonneauCovers.com has really good daily deals and generally cheaper prices for covers. Let me know where you guys have found the best luck!
  7. Zane Merva Executive Editor, GM-Trucks.com 3/5/2018 With the debut of GMC's all new and very fancy MultiPro Tailgate last week in Detroit questions have been floated regarding various aspects of the design and how available the tailgate will truly be. So, we reached out to GMC directly and have some answers for you. Here we are in no particular order: Will the MultiPro be available on any trim level other than SLT and Denali? YES. Although only the SLT and Denali trim levels were mentioned last week, we can confirm the MultiPro tailgate will be available on the SLE trim level as well. Can I open the MultiPro with the keyfob? YES. Just the tailgate as a whole, however. There's no option to open the inner section unless you do it with the button on the gate. Will the MultiPro prevent itself from opening into mounted ball hitch? NO. This is the biggest issue we can see with the MultiPro going forward. The inner gate is fully susceptible to damage from a mounted trailer hitch. GMC does mention that a warning sticker will be present to remind owners not to do just this. Owners will have to remember going forward that if they leave a ball hitch mounted, the MultiPro WILL HIT IT. Will GMC offer a manual (cheaper) version of the MultiPro later on? UNDETERMINED. GMC wouldn't answer our questions about a cheaper, manual version of the MultiPro in the future. We think it would be a great idea and GMC punting the question means the option is in play for the future. Will Chevrolet ever get the MultiPro? LIKELY. Although no-one from Chevy is talking, we expect the Silverado to get the MultiPro (or a Chevy-named version) at some point in the near future, perhaps in model year two (2020)
  8. Hi All, new to the forums, I just bought a 2016 GMC Sierra 2500 HD Denali and I’m having a hard time with the 110v power outlet. Ever since I bought the truck it hasn’t worked. I removed the passenger side panel and checked fuse #35 and noticed it was blown. With the truck off and nothing plugged into the outlet I removed the fuse and the second the new 25amp made contact the fuse blew instantly, I tried it again with another 25 amp fuse and same problem. Took to the dealer and they’re wanting to charge me $600 to diagnose the problem as they have to “rip apart my whole dash” to isolate the issue. I looked inside the outlet and nothing is inside that would short it out. Before buying a plug or an inverter I wanted to ask here if there’s anything else I should try? TIA
  9. I’m trying to install new front end parking sensors to my 2016 GMC Sierra like @pgamboa on his YouTube video. Only not sure what todo with the front bumper, I’m trying to save money and not have to buy a new one with the sensor holes since mine current one is in excellent condition. Does anybody know how can I get the layout for the holes for exact placement and size? I figured I can drill them out myself but I’ve already looked everywhere online and can’t find anything on this. My last option would be go find a truck and physically measure them out, can anyone help?
  10. Is anyone else having an issue where the automatic start-stop feature on the vehicle stopped working? I just got the truck about 3 weeks ago (Brand New) and this is the only feature giving me an issue. It worked at first, but after driving it a week, it has not worked since. The only modification I have done on the truck is change out the License Plate light bulbs from halogen to LED. I'm at the dealership right now and they can't figure it out, so they are trying to contact GM regarding this issue. No error codes showing up according to them.
  11. Hi everyone, I've inherited a 1978 GMC Royal Sierra. The truck has 59,000 miles on it and runs well. The body is in decent shape with some rusting near the wheel wells and in the bed. I'm hoping to sell the truck but I'm having a bit of trouble coming up with a fair price, so I figured I'd ask for some help. Given the mileage and pictures how would you price this truck?
  12. Similar to the 18" post, I want to see a thread with a 100% stock setup and what size tires you put on for 20" stock wheels only. This thread is not for leveling kits or aftermarket wheels. Post up some pictures! Let us know what size your tires are and what kind. I'm really only interested in doing very minor trimming if needed. My last truck I just had to zip tie the liner a little further back. Thanks! My current stock AT4
  13. 2016-2018 GMC Sierra Elevation grille that's been professionally painted black. This is a brand new OEM grille. I bought it from a member on here, but also decided to go with a different grille. The grille itself looks fantastic, the only reason for going with another grille is I have seen another truck identical to mine with the same grille, and I want to have something different... $500 shipped. Only asking what I paid for it. Current location: 54016 Thanks!
  14. It's October 2019 and rumors are swirling around a potential General Motors Electric Pickup, code named "Project O" We just covered this news here: https://www.gm-trucks.com/your-first-electric-pickup-may-be-a-hummer/ We've created this forum as a place to discuss these future electric vehicles and the news around their development in the leadup to 2021.

  16. John Goreham Contributing Writer, GM-Trucks.com 9-11-2019 General Motors has announced that NHTSA is mandating a safety recall for the following vehicles: 2014-2018 Chevrolet Silverado and GMC Sierra Pickups (1500 / 2500 / 3500) 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles 2015-2017 Cadillac Escalade NHTSA reports that the amount of vacuum created by the vacuum pump may decrease over time. The group says that as the vacuum level drops, the brake assist decreases, and that this increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash. This new recall covers 3.4 million vehicles. The Problem: The brake pump uses engine oil to lubricate itself. If the pump becomes clogged with engine oil sludge the units ability to create vaccum is diminished over time. As a result, braking force and ability also drops. The issue is usually accompanied by a "Service Brake Assist" warning message in the dash. The Fix: GM will reprogram the computer that controls the secondary brake assist pump. The secondary pump will now activate at lower speeds and different situations quicker to compensate for any lost output from the main pump. Since the pumps are not failing, GM has decided not to replace them. GM's number for this recall is N192268490. In compliance with federal law, GM will notify owners, typically by snail mail. GM says that its dealers will reprogram the Electronic Brake Control Module. However, GM has not yet provided a notification schedule. Owners may contact Chevrolet customer service at 1-800-630-2438, Cadillac customer service at 1-800-458-8006 or GMC customer service at 1-800-462-8782. If you own one of these vehicles and wish to check to see if your vehicle is included (or not) you can do so at this link immediately. As with every safety recall, customers will not be charged by GM for the needed repairs or modifications. NHTSA's public information on this issue indicates that many accidents have been reported to NHTSA including some with injuries. This recall is the result of a NHTSA investigation that lasted nearly a year. In its investigation report, NHTSA noted the following details about the problem:
  17. Looking to lift the front end of my 06 GMC Sierra 1500 2WD to lessen some of the factory rake. I have about a 3.5in difference from the back to front. Looking for about 2-2.5in of lift in the front. Any suggestions on what i can do to get the lift and if you have any product recommendations that would be great. I don't mind paying a little extra for something of good quality. Thanks!
  18. Zane Merva Executive Editor / Publisher, GM-Trucks.com April 26th, 2019 Our friend Tim Esterdahl from Pickup Truck and SUV Talk got an awesome chance to tour the Ft Wayne Assembly Plant. That's one of the two plants that produce the 2019 Chevy Silverado and GMC Sierra. Tim's tour was narrated by GM's Executive Chief Engineer Tim Herrick. Sit back and enjoy this look inside the manufacturing of the all new Silverado and Sierra. And if you like what you see, subscribe to Tim's YouTube Channel.
  19. I have a 2013 GMC Sierra 1500 SLT that I just bought and I am looking to hookup an after market subwoofer and amp but I like the stock dash look so I don't want to replace the stock radio (which would make this process a lot easier). Would I just replace the stock sub and amp and splice into the current wires? Could I keep the stock sub and amp also while connecting new sub and amp? Does the stock radio have RCA connectors in the back that I can connect too? In a perfect world I would be able to add a new sub and amp without replacing the stock sub and amp and still have a high quality sound system without using RCA plugs since I do not think they come on the back of the stock radio.
  20. Hello Everyone, I have been looking at adding a couple of cameras to my 2019 GMC Sierra 2500HD Denali. These trucks can be difficult to pull into parking spaces and lots, especially if they are smaller. I just recently raised the front end about 2-3 inches, this has made parking a even bigger challenge. Yes, when parking I try to back into most of the parking spaces, but sometimes that option isn't available. The system I have been looking at is from Echomaster, this system is listed under GM accessories and is labeled Intellihaul. The multi-camera system comes complete with a interface module, wiring, two (2) cameras that are mounted within a black mirror trim piece that attaches to the bottom of the mirror. The trim level on my Denali comes with trailer towing mirrors that are all chrome, and I really didn't want to substitute the lower black trim pieces in place of the chrome. I have seen one and it didn't look that good, on the all black mirrors they look OK (Just my preference). Echomaster has just recently released a new 3rd brake lamp camera that has three (3) different viewing angles within a single camera, a right 95 degree, a left 95 degree and a rear 90 degree. Then all I would have to do is add the front facing camera. In this arrangment, I would have to utilize a multi-camera module, this module is complete with wiring harness, bracket and OEM interface jumper cable. However, the new released 3rd brake lamp camera only has one (1) video output. I would have to hard wire 3 more input triggers to make this function correctly, the left and right turn signals and reverse triggers. To operate on the OEM radio screen, I would have to depress the "back" button for three (3) seconds until the camera icons appeared on the screen. This would give me the rear cargo area. To view both the blind spot camera views, I would have to cycle the left or right turn signal depending on which camera I want to view. I would also have a front facing camera installed in the grill area, which would assist in parking manuevers. In this setup, I still would have full operation of the OEM backup camera when in reverse. I think this would be a good option and give me what I was looking for. When I talked to the tech assistance at GM this afternoon, he said that the system would be awkward to operate. I would like something that is plug-n-play, a system that I didn't have to rely on to take to dealer to program the radio, BCM or any other related modules. What is everyone doing about adding cameras to your truck, what sytem and options have you looked at and/or are utilizing? Do you like your truck with the camera addition? What are your thoughts? Thanks,
  21. It feels like a dumb question but me and my friend want to turbo my 2002 gmc envoy slt, it's a 4.2l in-line 6 with all stock internals I'm not sure how strong the factory internals are on that engine and we want to know what we should replace if we even have to. I was thinking lower compression pistons, rods and bearings. Anything I'm missing?
  22. Now that owners are taking delivery of the new 2019 Chevy Silverado and GMC Sierra, I thought a quick reference guide to common routine maintenance items would be beneficial to us all.

  23. Anyone have issues with a coolant leak the dealer “can’t find”. I bought my l5p denali duramax about 6 months ago and have put 15k on it in those 6 months. Mostly used for pulling my 43’ fifthwheel. Anyway the issue. At 3k the low coolant light came on and I brought it to the dealer. I was told air had not been properly removed from the cooling system when assembled so they burped it and I was on my way. I was good till 11k miles. At 11k the light came on again and I brought it in. The radiator was replaced, brought it home and started it a couple days later and the coolant light came on. Called the dealer same story burping air out so I topped it off myself. 11k noticed coolant puddle under it and coolant drips on passenger frame rail by front bumper. Brought it in and dealer couldn’t find a leak so I took it home. Two days later the coolant light came on and multiple drips were on the frame. So at this point I have executive GM involved with trying to figure it out. A couple things at this point have me worked up. Not one time was I offered a loaner car not once. After the radiator was replaced they put The plastic skid plate one under the radiator and broke it and left it on. So now I want a loaner when I drop it off. I wait almost a month before they give in and give me one and bring the truck back in. At this point the over flow is almost empty so it’s not leaking very fast. The truck now has 15k on it. I bring it it in and get a loaner car for the first time with 15k on it and the 4th visit in 6 months. Dealer still can not find a leak. I asked them to climb under they truck and look at the frame rail for coolant. He calls back and says it’s dry. So I send my wife to pick the truck up. She drives 15 miles home from the dealer and that’s it. When I got home from work I checked under the truck and it’s dripping coolant. So a couple of things so far, executive GM has done not one thing to help me out. I have done everything myself. They don’t return calls and do not return emails. The last time I brought my truck in the dealer refused to give me any paperwork showing that they actually looked at it they just gave me paperwork from my previous visit. He service advisor keeps telling me it’s burping out air and it’s residual coolant from the radiator replacement 4K miles ago and 2 months ago. I don’t know what to do. I have lost all respect for GM and their product.
  24. After 1 month of owning my new 2019 AT4 without any issues, I had the Nav SD card not installed error. The next day, the nav system went through s long loading process. Since then, with every vehicle startup, I now have a 10-25 second process of the nav system loading before it can be used. Previously, it was always nearly instantaneous. Also, the radio will be randomly self-muted. I brought it to the dealer last week and they did an infotainment system software update claiming to have fixed the problem. Nope, it’s still taking 10-20 seconds to load navigation and the radio was muted this morning. Anyone with 2019 Sierra AT4’s or Denali’s noticing a change in navigation loading, specifically now seeing loading screens where there haven’t been before? Is this just normal Nav function and somehow, for some reason, I just didn’t have it happen or didn’t notice it the first month? Could GMC pushed an OTA update that now cause the Nav to take longer to load?
  25. I installed an aftermarket billet grill on my 2014 GMC Sierra. The horizontal segments of the grill are pretty close together. The truck looks great but now I have wind noise. 20-40 mph I get a humming noise and then higher speeds I get more of a whistling sound of various pitches. Doing some internet hunting, I've seen suggestions of stiffening the horizontal sections by gluing on vertical supports. I've also read about coating the back side of the grill with silicone or some other rubberized-like coating. But I'm not sure how that would fix it. Is it just interrupting the trailing edge of the horizontal members and that stops the noise? Some have suggest adding a mesh behind the grille as well. Anyone have this problem and a sure fire solution (other than getting a new grille!). Thanks!
