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. If you have information that you'd like suggest be added to this topic, just post below and I'll update this first post with any and all new/updated information.

Those fuel tank sizes (I know, beating the dead horse) are ridiculous. Give us some range, damnit!

      Alright... let me take a deep breath...
      I just bought a 2019 Chevy Silverado Custom Trail Boss.
      I am having an issue with my 2019 Chevy MyLink infotainment system and its integration with my Note 9 since the Android Pie update.
      The issue: When I receive a phone call through Bluetooth OR Android auto, I am able to answer the phone call but... The ringer will NOT stop ringing on my infotainment system. The only way I can talk to the person on the other line is by picking up my phone and disabling it from the infotainment system (this did not happen at all on the previous software version and it was glorious). The ringer will also never turn off even after the phone call is ended. The only way I can turn the ringer off while driving is by turning it down (cannot switch back to radio to continue listening to music, which is very aggravating), so I am sitting in silence for the remainder of my trip... unless... I pull over on the side of the road, shut my vehicle down for 2 minutes to let the computer reset and start it back up. This issue does not occur on my work iPhone either...  I thought that it might be an issue that chevy's infotainment support team could solve... It seems that it is not their issue because it only happens to android Pie software version phones and not any others. I call Samsung... do everything you could think of to troubleshoot this issue (finally factory reset my phone completely only to NOT resolve the issue). Samsung seems to believe that I need to send my phone in for a repair (even though it wasn't happening with the previous software version). Chevy thinks I need to just wait for a new software update for Android Pie... but I hate waiting because it is a very aggravating issue and love my music! Is ANYONE else having these same issues? Is there a solution that anyone can think of? I would like to just revert back to the previous software version and forget about it, but I am not sure of the problems that may cause...

      Curious to know who in this forum has the highest mileage truck. Just took delievery of my new 2018 truck with the 5.3 V8 and 6 speed tranny and wondering how long I should expect it to last? Coming from a Toyota with about 350k kms I have set the bar pretty high haha. Feel free to post the year of your truck with the # of miles and what repairs/replacements you have done to date. Trying to get a little thread going about mileage and what people have been able to get. Since this is a 2014 forum I'm not expecting massive numbers, but I know some of my friends with Rams that have had engines and transmissions break down at 50k-80k kms (moment of silence for Ram owners) Ford seems to be doing a bit better in terms of major issues. If there's already a thread regarding this issue please redirect me to that one

      An exciting but anything-but-confirmed rumor has started to swirl around the GM performance community recently. Here's two completely independent reports I read in the last 24 hours. 
       
      With the sheer number of white collar jobs currently being "resized" at GM, it's no surprise that anyone working on future product development might feel a little salty and inclined to chat about the projects they were working on. Does this mean these products are in development? MAYBE. We see three likely options. 
       
      Option 1- The Rumors Are True: That means the next generation Escalade will get a V-Series variant with the 650-horsepower Supercharged 6.2L LT4.  If that platform was packaged for the Escalade, slapping it into a Silverado and calling it an SS would be child's play and the most likely next move. GM has been criticized for lacking a true performance truck for a long time and this could make up for the absence.
       
      Option 2- The Rumors Were True: But not anymore. In this scenario, the leakers who knew about the projects were let go because the projects were canceled. This is also a likely option. 
       
      Option 3- The Rumors Are Not True: The whole thing was made up and taken out of context by hopeful GM Performance Enthusiasts (myself included). It was wishful thinking anyways...
       
      Stay tuned to find out exactly which option it was. Maybe it's option #4?

      GM-Trucks.com is always trying to stay on the bleeding edge of General Motors vehicles and the aftermarket accessories that owners install on them. That’s why we occasionally purchase long term pickups to better understand the ownership experience of these extremely popular vehicles. Our last truck, a 2011 GMC Sierra All Terrain, continues to serve us well all these years later, but became outdated in 2014 when the K2 generation of trucks was produced. We never had a chance to purchase a 2014-2018 Silverado but had a half dozen close friends who let us work on theirs.  
       

       
      So when GM announced that the 2019 model year Silverado and Sierra would be brand spankin' new, we knew we had to have one. Thus, a year long effort was set into motion during the Winter of 2017-2018. Internally, GM-Trucks.com declared war on the 2019 Silverado. We could cover it, we would own it, we would be THE place for owners of the T1XX generation to call home. To do that, we had to have one ourselves. 
       
      We saw the surprise unveiling, followed trim level news, ordering information, factory startup, placed an order the first day we could, then waited (not so) patiently for it to arrive. In September 2018 we took delivery of our new 2019 Chevrolet Silverado LTZ. Here it is a few seconds after the first time we saw it.
       

       

      What’s the plan?
      We’re going to make our new Silverado work for us and you. Over the next few years we plan on transforming our truck, installing loads of aftermarket parts, and reviewing everything in the process.
       
      Our thought process behind this Project Truck is simple. We originally wanted to buy a Silverado Trail Boss but found that Chevy wouldn’t let us get it with the all new 6.2L V8. That engine and the brand new 10-speed transmission was reserved for those who purchased an LTZ or High Country. With the 6.2L being more important, we acquiesced and ordered a more expensive LTZ instead.  Thus, our mission to replicate the Trail Boss’s off-road stance and beefed up attitude but with a legendary 6.2L engine and a more luxurious take on things was born. We've decided to call it….
       
      Project Trail Beast
       
      More than just a name, Project Trail Beast is a set of core vehicle modification goals that we’d like to accomplish with our 2019 Silverado LTZ. The ultimate goal is to create the truck that Chevy should have made… a Trail Boss with a 6.2L engine.  Thankfully, we’re not bound by factory parts anymore, so we can go a little more hardcore than Chevy would have. 
       

       
      Our goals include:
      Suspension Lift: We’ll take our Silverado and raise it a modest 2-4 inches. More aggressive tires are a requirement and aftermarket rims are being considered to complement the higher stance without sacrificing driveability.  Beefed Up Performance: 420-horsepower stock isn’t bad…. but isn’t nearly enough. We’ll explore adding a supercharger to our 6.2L and work with leading brands to install performance intake and exhaust systems. We’ll also check in on the custom tuning scene and how the 2019 models can be modified on the inside.  Updated Lighting: Even though most of our Silverado has high tech LED lighting, there are still some conventional bulbs. We’ll replacement all with the latest LED tech and add additional illumination around our truck. Expect us to talk about and review industry players such as Sylvania and Baja Lights soon.  Utility Accessories: We'll explore bed covers, floor mats, security products, custom keyed locks, ceramic coatings, and a wide range of other accessories that any truck owner may use or need on their vehicle. From Adams Polishes to Husky Liners, we’ll look at what works and what does not.  GM Official Accessories: GM is upping their game and offering lots of performance and visual accessories right from the dealership. We opened up a parts account and immediately started buying. How do these products perform? Are they worth the price? We'll let you know  

       
      Help Us Out! What Do You Want?
      Do you want a particular product reviewed? Can't decide on a truck safe? Or confused about Ceramic Coatings? Let us know! We’ll do our best to review anything we can on Project Trail Beast. Do you work for a company who has a product you’d like us to look at? We can do that too. 
       

       
      What’s next?
      It's time to get installing. We have a fat pile of accessories we've already started to work on. Each product, each experience, we'll share with you. Stay tuned for more updates on Project Trail Beast.
