Hi just wondering if anyone would be able to help. My truck makes this rattling noice when being accelerated. When it started it wasn't that bad but has progressively got worse. It's worse when it's cold then goes away for the most part once the engine is warmed up. Sounds like it's coming from the front end. Thank you! 20220307_163644.mp4

Ok, so while I was in a forum for a different truck brand I started a thread for just random talk, and pictures. I just purchased a 2021 SLE 2500 and will get a few pics up as soon as it stopes snowing and I get her clean. Look forward to chatting with the rest of ya T

Thom Cannell Contributing Writer, GM-Trucks.com December 6, 2018 Last month Chevrolet invited us to test the Chevrolet Bison, a ZR2 derivative with distinctive upgrades that add to its already solid off road capabilities. Built off the already-capable Z7R2, American Expedition Vehicles (AEV) provided the collaborative additions that created Bison. It retains the class-exclusive front and rear locking differentials from ZR2, and high-zoot Multimatic DSSV dampers. The design of the Dynamic Suspensions Spool Valve dampers uses hollow cylindrical sleeves instead of familiar discs. These were used first on race cars including Champ cars, LeMans prototypes and F1 They provide superb off road damping, particularly on rough trails where they offer greater passenger comfort. Getting to the grit of it, a pickup is hard-pressed to have the approach angle of a Jeep, and impossible for a production bed to provide a really short departure. Nonetheless, Bison does a very good job of going over rocks. One of the AEV additions is a set of five hot-stamped Boron-steel skid plates to protect the oil pan, fuel tank, transfer case and front and rear locking differentials, which we tested extensively. “As this is the first Chevrolet vehicle we’ve given the AEV treatment to,” said Dave Harriton, founder and president of AEV, “we wanted to do something special with the industry’s first use of hot-stamped Boron steel.” We think he’s referring to the off-road industry, as hot stamped High Strength Steel is the basis for modern crash-worthy chassis. However, those skid plates kept the rocks out of our oil pan. Some of the Bison upgrades are more cosmetic than necessary, like replacing the bowtie grille a free-flowing CHEVROLET front grille, Bison decals on the bedsides and an AEV Bison logo on the tailgate plus an embroidered AEV on the floor liners and front head rests. Branding, eh? Performance-oriented changes include the stamped steel front and rear bumpers. The front bumper allows adding a winch (would you go off roading without a winch??), fog lamps and integrated recovery points. As a truck designed to venture deep into open spaces, Chevy added 31-inch Goodyear Wrangler Duratrac tires mounted on Bison-specific 12x8-inch aluminum wheels. We tested those, too, and they have plenty of grip on rocks, and in loose dirt. Note that the ZR2 cast-iron control arms and Autotrac transfer case are retained, along with the ZR2’s 3.42:1 axle ratio and front/rear tracks wider by 3.5-inches. Compared to a ZR1, Bison is lifted by two-inches. Our test vehicle was powered by the new 2.8-liter Duramax diesel (186 hp., 369 lb.-ft.) mated to a six-speed transmission. It was the crew cab model; with the short bed which including some AEV upgrades. On our highway drive towards an off-road park, we noted that the Bison was extremely quiet, and not just “quiet, for a truck”. No, it was quiet for any kind of vehicle, including a Cadillac. After switching the transfer case into 4WD-high, we bucked our way towards the promised bigger challenges. Along our trail—nothing extreme but way off the beaten path—we again noted there hadn’t been a single squeak, rattle, or buzz. The only odd sounds in the cabin were from the zippers on our camera bags. Bison’s frame is stiff; there’s no tweaking, everything is absolutely tight. There was no way to call out the suspension and its Multimatic spool-valve-type dampers, however the suspension was supple on the rough trail. Another noise-related note, we picked up no rock noise in the wheel wells despite being pushed around by potholes, rocks and dips. We might as well have been on the freeway, from a noise perspective. Our truck had almost every American Expedition accessory available. There were LED fog or trail-search lights on the hood, a ladder rack and a storage bin system mounted below a false bed. We only lacked the Baja-style intake snorkel. The bolted-on roof rack may have added stiffness to the already ultra-stiff box frame, which allowed the suspension do its work. Watching the vehicles ahead of us, we could see how steady the beds were, and how much the suspension was working. For a stock vehicle, there was plenty of travel available. Bison has a solid rear axle and independent front suspension, and there is a divide among off roaders and rock climbers as to whether a solid axle or independent rear suspension is better. Rock climbers seem to prefer solid rear axles. We thought the ZR2-based Bison chassis with a Duramax diesel made off roading almost a no-challenge event. The diesel engine was totally on-point with torque, needing only a light application of brakes for stability when balancing on rocks. Comparatively, those who had the standard V-6 gasser had a harder time of it, using more throttle to obtain torque, then having to feather the throttle and brake to stay on track. If you've never done rock crawling, you must apply power to get up, apply brake to stop, before being guided down in the correct direction. Yeah, it's really hard to see the front wheels through the engine. One of the options Chevy will offer through dealers is a shorter, cut off exhaust tip. We strongly recommend this if you’re going rock crawling. Many of us “modified” the longer exhaust tips when crawling off rocks. After crawling a rock canyon we grouped to head for lunch. Parked on a hill with loose sand and the tranny set in 4WD high, there wasn't enough traction. Locking the rear differential made climbing the hill as simple as stepping on the throttle, in that low traction situation. Having complete control over axles and each wheel made off roading and rock crawling easy, even for beginners. Note that, in our opinion, the Duramax doesn't deliver optimum fuel economy for the Bison. It's good, but not great. Where it shines is in torque availability for off roading. We can see the Bison with Duramax as a perfect combination for off road camping, adventuring, and modest towing. It's quiet. While on our rock crawls, there was never a sound from the chassis, no wracking, graunching, squeaks or rattles other than when we skidded over rock on those Boron steel protectors. It was billet solid. In fact, we'd go so far as to say our Bison was quieter than a standard Silverado and totally ready for any off road adventure. Interested in the Colorado ZR2?

Dears, I bought my 2017 Chevy Colorado Duramax Z71 brand new and I just love it. I was super satisfied with the performance and features of the truck. Due to the nature of my job, I had to move outside the U.S for a long mission to Africa, so I took my truck with me. Here started my nightmare. Just few days of use, I had the famous warning message regarding the quality of gas (DEF). I changed several brands of DEF but no success! I read somewhere that the shelf life of the product is key for the quality of the fluid. Now my truck is kind of locked, I am allowed to drive 6 Miles/h, it means it is not working. The worse thing is that there is no GM, Chevrolet store to assist. I was thinking to delete the whole DEF system if possible since the location where I am based is not regulated by the gas emissions. I will be very grateful if you could assist as I am suffering without my car. Thanks for your help.

Zane Merva Executive Editor / Publisher - GM-Trucks.com October 8th, 2019 Chevrolet is ready to race the 2021 Colorado. Like, really ready to race. This week in fact. The new face for the Colorado mid-size truck will make its public debut October 10th during the 2019 Method Race Wheels Laughlin Desert Classic and will be driven by Hall Racing. Here's a sneak peek at the all new face of the Colorado. Chevrolet also gave us a showing of the production 2021 ZR2 that will debut in one month at the 2019 SEMA Show in Las Vegas. Check back with us in November for our first hand take at the new ZR2 when we visit the SEMA Show. Anyways, let's take a look at the changes. What's new with the 2021 Colorado? First off, the changes so far seem to be cosmetic and packaging only. No new features or changes in specs have been announced yet. However, the exterior has been warmed over to bring it in line with the Silverado's front end, without breaking the bank on a full redesign (which is expected in the 2023-2024 MY time frame). Here's the announced 2021 changes. New front end appearance for ZR2 model. Only Colorado model to have "Flow-through Chevrolet Fascia". WT, LT, and Z71 trim levels will receive updated center bars, lower fascias, and new front skid plates. WT and LT will feature "all-new" gold Chevy bowties while the Z71 trim is adorned with a black bowtie. All models receive embossed 'Chevrolet" tailgates and ditch the traditional bowtie on the rear of the vehicle. A new "Sand Dune Metallic" will be offered on Z71 and ZR2 models only. What do you think about the new face of the Colorado?

Has anybody had this happen to their grill? The plastic looks like it melted, but were the paint is....

I have a very nicely equipped 2017 Chev. Silverado z71 Quad Cab. Only have 6500 miles on it and bought it as a kind of retirement gift for myself. I use it for various things but mostly to go fishin or huntin in and tow my 18 foot Basstracker. The issue I am having is backing my boat back into the garage with it. I live in town on an alley and it is very tight trying to get the proper angle backing into the garage, especially if the neighbor is parked on the other side of the alley. I am wondering how much I might be gaining in maneuverability by trading it in for a smaller truck? Anyone have any experience with this? Thanks for any help.

Recently installed a Blackvue DR590W 2-channel dash cam system into my 2019 Canyon. I used a Powermagic pro to hardwire it to the vehicle, and a Blendmount to attach it. Really like the video quality of these cameras. Check out my install video.

John Goreham Contributing Writer, GM-Trucks.com 5-10-2018 A Colorado ZR2 owner, Joe F., at the Facebook Colorado ZR2 Club has reported a disturbing airbag deployment that occurred during some relatively benign soft-roading. If you’d like to jump directly to the club’s page you can do so here. Joe’s truck was just under a month old when this occurred. He had not modified the truck in any unusual way. He had added a winch and LED lights. Other than that his truck was bone stock. Joe says that just prior to the side curtain airbag deployment, “I was moving up a hill slowly in 4WD LOW with OFFROAD MODE on, passenger side wheel in a rut which had me leaning to the right. It certainly wasn’t leaned over too much. Going maybe 3 mph.” Joe’s image above shows the road that he was on. Joe says the event “…was quite a violent deployment (explosion).” He was not injured, and the truck was able to run after the event. Joe has provided a long version of the events that took place after the improper deployment. He has had difficulties with GM. Neither the dealer nor GM wants to handle fixing the truck, which has an estimated repair cost of $6,500. Since the circular firing squad is only just now being put together, we will hold off on saying GM won’t take responsibility at the end of the debacle. You can read Joe’s full overview of the situation to date at the link above for all the gory details on his struggles to get help. If Joe posts a final outcome story we will update this post, or add another. This sad story leaves us wondering if any other GM-Trucks.com members have ever had an airbag deploy during off-roading. YouTube does have some videos of airbags deploying when they should not, but there are surprisingly few. If something similar has happened to you, or you witnessed it happening, please give us the story.

Installed a set of iBoardAuto running boards on my 2017 Coly. Check out the install and review videos below: INSTALL REVIEW

Please help I have been to the dealer multiple times in the past few weeks for my 2019 Chevy Colorado. They are struggling to fix this issue and no one really knows how to fix it. It keeps saying the SD card for Navigation has been removed when it hasn't been. I have an iPhone X latest update. The bluetooth comes and goes too when the navigation does. Bluetooth for phone calls will work but music won't play and I have even tried my moms older iPhone and it still does the same thing. The dealership has replaced the SD card, the whole front USB port, and the radio system unit. It still did it today and bluetooth music comes and goes like the SD card reader error for navigation. Any one else experiencing anything on any GM cars?? I also have the latest version of the infotainment system and I'm wondering if the update messed is messing it up like some kind of bug.

Just actually stumbled across this page while browsing coloradofans. Jeff from Dallas Texas, 2018 Colorado 4x4 LT, basically Stock as it's my daily. Also have a 2018 Camaro ZL1. I need some help, before I start looking at all of your trucks, mods, other cool stuff.. (copied this from coloradofans.com, also from a few subs on reddit..) Hi all, need some advice- Let me preface this with, I am not trying to get anyone in trouble nor an I trying to throw anyone under the bus. I just want my Colorado fixed. I appreciate anyones feedback as I explain the story. 2018 Colorado LT, 4x4, 30k miles.... About three weeks ago, I had an appointment at my local Chevrolet dealer, which is a very large dealer in the Dallas/Fort-Worth metroplex. The truck has a very weird sounding, only can be described as an intermittent, yet ANNOYING and LOUD squeaking/rubbing sound coming from what sounds like the front of the truck. I showed up to my appointment, and the service advisor and I went for a ride, and he said that he could barely hear the sound, but I was able to hear it as clear as day. He also pointed out that he heard it when we accelerated, and when we braked. Nothing when we were coasting, not using the brakes, etc. He told me that I would have to leave it with him for a few days, or get there early on a Saturday for his guys to take it in. I didn't have the ability to do that at the time, so I told him I would reach back out in about a week or so. Fast forward a week - I was to be traveling so I was going to leave the truck prior to leaving the DFW airport. I ran some errands in the morning, and after getting the truck up to operating temperature, It is not making the sound, at all. Unfortunately I did not have the time to deal with this at the time so I went back to my house, and hopped a ride to the airport. Once I got back, and started my routine I noticed that the noise is still back and I can still hear it as loud as day. I made an appointment for 8:15 AM on last Tuesday. I showed up at 7:30 and they got me checked in. We took it for a ride around the lot, and the service advisor heard the noise. He got me right in. the shuttle took me to work. About three hours later he called me and he said - and please bear with me, I am no mechanic and my terminology may be off - "There was a seal in the transfer casing that was rotted..we fixed it, blah blah..and now it is not making the noise, OH, and you need an oil change. Want that while you're here?". Hopped an uber back to the dealer on my lunch and drove back to the office. Everything seemed fine. I got out of work around 5pm that day and went to the grocery store, sure enough, the noise is still there, and louder than ever. I am getting frustrated at this point. I reviewed the work order only to find out that it mentions nothing about fixing anything, only that the tech could not duplicate the issue I described. At this point, I am very hesitant to go back to that dealership, so I reach out to some other local enthusiasts for a referral, and I make contact with someone who works at a dealership about 30minutes south of where I live. I was to stop by Saturday morning, and ask for his buddy the service advisor. No problem at all. I stopped in right on time, met with the advisor, we took it for a ride around the lot. Sure enough, there it is! The noise on the stop, and on the go! He heard it, I heard it. But he told me that they won't get to it until Monday because the suspension, front end guys, etc, won't be in. I say OK, Whatever it takes. I also say, hey since I am new to town and need my registration switched, can you guys please do a safety inspection? He says yeah no problem. Another $35 uber back to my apartment. Today I get a call. And now, I am being told that the noise I am hearing is the noise of air going into the engine, and it's louder because I have a K&N Blackwing Cold Air Intake system. Which makes absolutely zero sense, since the noise only happens on the stop and go, and it's also a grinding/rubbing/squeaking noise. However, at this point.. I am not arguing. Because I have a short temper and I really don't want to be mean right now. You catch more bees with honey than vinegar. I just picked it up, and it's still making the same noise. The intake is not causing the issue.. and I don't have the stock one as I just moved here. I'm not a mechanic, but that's the stupidest **** I've ever heard. I have had intakes on all of my cars. There's one on my 2018 ZL1 camaro, no noises like that. I had them on my 2016 SS, 2015 C7, etc.. Never had any issues. The only COMMON issue here is that much like in the past like I've dealt with Pontiac back in 2009, the dealership is using any kind of excuse to not have to do any work at all. (Example - in 2010, broken ball joint on my 2009 g8 gt - they blamed it on my roto-fab engine covers hitting the hood, when in fact, it was a MAJOR TSB..) So a couple of things. 1) Where in DFW can I go to get this fixed 2) Should I even bother calling the GM customer care number.. because I am SERIOUSLY SICK OF "NO RENTALS BEING AVAILABLE" and having to pay for an uber. It's going to cost me $36 to get to the dealer tomorrow to pick the truck up. 3) Any other advise. Thanks in advance.

John GorehamContributing Writer, GM-Trucks.com11-8-2018 General Motors made an unusual request today of GM-Trucks.com. Our contact at the Chevy Truck department asked us to report that GM is launching a new campaign to adjust the sensitivity of the airbags in the Chevy Colorado ZR2. This is a refreshing change from the industry standard practice of soft-pedaling recalls and product programs. Here is the unedited information we were asked to convey: As you are aware, there have been reports of Colorado ZR2 owners whose roof-mounted side airbags deployed while off-roading. Upon learning of this issue, Chevrolet took immediate action to understand the root cause and create a solution. Today, we notified Chevrolet dealers of a customer-satisfaction initiative to recalibrate the thresholds for the roof-mounted side airbags for ZR2 owners. The updated calibration is available as of today, and will be installed free of charge the next time the customers takes their ZR2 to a Chevrolet dealer. There have been 11 reports of Colorado ZR2 owners whose roof-mounted side airbags deployed while off-roading. Chevrolet is working to reimburse those ZR2 customers for the cost of repair, provided the event data was available to confirm the incident. We are incredibly proud of the ZR2 and the off-road capability it offers, and are encouraged to see customers are using the truck as intended. If customers have questions, they should contact their local dealer or Chevrolet Customer Assistance at 800-833-2438 GM-Trucks.com readers may recall that in May we covered the news that owners were beginning to report that the airbags in their Colorado trucks were deploying while off-roading (and not in a crash). You can read the prior full report here and see more images. Our reporting leaned heavily on images and reports from GM-Truck.com member Joe F. Since Joe's information was made available, other owners have also reported the same problem. We will do our best to get new information from Joe F. and how he is reimbursed. Our thanks to GM for asking us to be involved in disseminating this important product update program.

John Goreham Contributing Writer, GM-Trucks.com 5-15-2019 The same folks that GM turned to for the specialty equipment on the Colorado ZR2 Bison have created a fantastic tray bed concept of the truck. America Expedition Vehicles (AEV) built the concept for Overland Expo West. The concept truck shows off new high-clearance fender flares that AEV has developed. AEV took the new tray bed concept Bisons on a three-day off-road desert adventure to see how well they new bed would hold up. The post-trip report is that it worked flawlessly. The new fender flares allow for the fitment of 35" wheels without a lift kit. The new tray bed and fender flares are presently in development. AEV hopes to have more information for those interested soon. Follow AEV via its website, or at the company's Facebook page. Images courtesy of AEV and Scott Brady.

Our 2017 2WD Colorado Z71 with 33k miles started making a knocking sound at low speed, worst at around 20mph, sometimes more noticeable than others. First the dealer put it down to normal tire noise, then a few months later when the noise got worse said it was cupped tires and that we needed to replace them. They recommended less aggressive tires as the "stock" all terrain tires always cup and make noise apparently. So, we had a new set of tires put on and the rhythmic thumping was still there, more obvious now that it wasn't masked by tire noise. The noise seemed to come from the front of the car and was noticeable at low speed 10-20mph and would speed and slow with the car. Once you're tuned into it you can hear it/feel it around 40mph too but its more of a vibration. Took it back to the dealer and test drove, they heard the knocking and decided to replace both front hubs under warranty. When we picked the car up they said the noise was gone other than normal truck noises, on the drive home it obviously wasn't. In fact it's worse under some conditions. Now it seems that either the problem is getting worse or we're hearing/feeling things that aren't there. The knocking has become stronger but only sometimes, and at highway speeds it feels like the whole truck is buffeting and vibrating. It also seems to be slipping gears, or shuddering between changes at low revs. Having taken it back tot he dealer they say there's nothing wrong, they can't hear or feel any problems, and to be fair to them the knocking was less noticeable when I drove it with them but the vibration and shudder was there. I did ask to drive a new one so I could feel the difference and perhaps it's just normal but they didn't want to do that. I've now left it with them and asked them to test drive it more and if they're happy there's no problem then I'll pick it up and if it comes back I'll take it somewhere else for an independent test. We're 100% sure on the rhythmic knocking/thumping, especially as it's the same issue before and after the tires and hubs were changed, perhaps this is normal. As for the vibration and buffeting we're less sure, it does seem like it's slipping gears and shuddering but after so much focus listening to the thumping perhaps we're just seeing problems where none exist. Does anyone else have any similar experiences, or are we truly just going a bit nuts?

I ran across this for you Colorado fans. I did not dive into the configurations, but as the title suggests you can run a Colorado up over 50k This is NUTS for a " Mid-Sized " Truck. You can get a discounted Full size Silverado for less than this. Yes its a bigger truck but it is insane that smaller trucks are pushing 50k. Then again, it is NUTS that full size trucks are hitting the 70k mark (2019 High Country and Denali). Anyway, Enjoy! https://www.tfltruck.com/2018/09/2019-chevy-colorado-here-is-how-you-can-configure-it-to-over-50000-configurator/
