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.

Sucks it took 11 trucks to get to this point, but at least they thoroughly examined them and came up with a solution.  Kudos GM.

It's certainly a step in the right direction.
How many reports will it take to address the (e.g.g.) flaking coating on the frames?

Maybe it's taken care of on the new model. The hope dies last.

 

so long

I’m happy to see GM responding to the issue.

 

Unfortunately, the ZR-2’s reputation has taken a bit of a beating as a result of the issue.

 

It’s amazing how much 11 instances of a problem, among thousands of trucks sold can get people talking. Base on how people were talking, I assumed there would have been more instances that were simply not being reported through the media.

I hope they don't use "lack of data" to burn owners who had the overly sensitive airbags deploy.

At least they handled it better than the ignition switch fiasco.

Wonder if they will extend the re-calibration to the Sierra/Silverados as well? I had mine deploy off roading on my 2015 Sierra....

Right now, the recall is only on ZR2 trucks, not other Colorado and Canyon trucks.  It's been well documented that the issue has occurred on non ZR2 trucks as well. 

 

Could you describe what was happening when the bags went off in your Sierra?  How fast were you driving?  Were there any significant angles involved?  Or was the truck simply jostling slightly going over some bumps?

GM took the truck and repaired it so the manufacture knows everything. It had 800 miles on it. They fixed everything but basically said don't off road it like that. :/ But it was on a slight sideways slope, and was bumpy, Speed was maybe 10-15 mph? it was 3 years ago. A same year Ram and my older Avalanche with side bags had no issue with the same run. Imho the rollover sensor was too sensitive, but far as I know no changes have been made.

I think this is why side by side ATVs now exist.  You used to be able to take a pickup truck off road, without worrying about it imploding, and self inflicting thousands of dollars of damage.  These days, so much on road safety tech and sensor driven traction management systems are being packed into trucks, taking them off road seems to make less and less sense.

I agree, the older trucks lack of safety features were better for offroading...I have 2 seat RZR I can put in the bed to offroad and beat up. It sucks when you break your daily driver haha.

      I have a set of 2019 Chevy Colorado rims that are 18x8.5 and 6x120 and they come with tpms already installed. These will fit any 15-19 Colorado and the tpms just need to be programmed to the vehicle. MSRP on these rims and sensors are $2310.08 before tax and core charge (which is $50 per rim). I'm looking for $1600 obo they do not come with tires or center caps. Message me if you have any questions. I have more pictures of the back of the rims showing they are genuine GM rims but they are to large of a file to upload.

      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.

      Chevrolet announced a new list today for Colorado ZR2 race components. The list consists of 15 off-road racing parts ranging from the ZR2's special Multimatic DSSV shocks ($4,187.50) to jounce shock systems ($1,231.35 front and $1,543.75 rear). The parts are presently all suspension-related. Chevy has not included any engine upgrade parts.
       
      These parts were developed by Chevrolet Performance in conjunction with Multimatic and Hall Racing. Chad Hall drove over 10,000 miles in two race series using beta versions of these components to wring out any bugs and to ensure a perfect final product for Colorado owners.  “Off-road racing is a brutal test of a vehicle, and especially its suspension components,” said Mark Dickens, executive director of Chevrolet Performance Variants, Parts and Accessories and Motorsports. “Over two years, Chad mercilessly pushed these ZR2 parts to the limit for the ultimate in development and validation. After seeing the success of the Colorado ZR2, customers have been hounding Chad for help building their own ‘Hall Racing ZR2,’” Dickens continued. “For the first time, you can buy the same Chevy Performance Parts that raced and won in the desert. All you need to add is the required safety equipment to build a pre-runner for scouting the Baja 1000 or a full-blown race truck capable of competing in the race itself.”

      Chevy says that these racing versions of the similar parts already on every ZR2 focus on desert running while preserving low-speed off-road performance. For example, the parts can add an additional 1-inch suspension lift and a 1.5-inch Body Lift on top of the ZR2’s factory ride height and up to 15 percent more suspension travel for extreme high-speed off-roading. AThe racing Multimatic DSSV dampers are engineered to go beyond the already formidable bandwidth of ZR2’s stock DSSVs. The available Multimatic Front Long Travel DSSV Shocks provide customers with a 15 percent increase in overall front suspension travel, while the Multimatic long travel rear shocks increase rear suspension travel by as much as 10 percent.
       
      “These parts can be purchased individually to suit each customer’s needs, or as a complete package,” said Dickens. “This gives customers the flexibility to build their truck up over time, purchase only the parts they need for their particular interest, or buy the complete set to build their own ‘Hall Racing’ ZR2.”  Jump to the new online list here.
