Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.

GMC Canyon AT4X rumored to get more extreme AEV Edition

When GMC debuted the new 2023 Canyon pickup in August, the midsize lineup gained the hardcore AT4X off-road trim the brand has been spreading throughout its wares. The new top-of-the-line model is GMC's version of the Chevrolet Colorado ZR2 and features the same off-road goodies, like the Multimatic DSSV suspension, unique front fascia, more skid plates, front and rear locking differentials, and a Baja drive mode turning the 33-inch tires. The Edition 1 launch model adds to the production goods by bolting on a front safari bar with a 30-inch light bar, a Comeup winch, an upgraded front skid plate, reconfigurable bed rails, front and rear underbody cameras, and special badging. The Canyon AT4X Edition 1 was gone almost immediately, because of course. However, Muscle Cars & Trucks reports that something just as special could be coming for buyers in the form of a Canyon AT4X AEV Edition. American Expeditionary Vehicles already breathed all over the last-gen Chevrolet Colorado and the current Chevy Silverado, looks like GM not only intends to keep the relationship going but expand it. MCT credits a source for news that the AEV-worked Canyon will get a snorkel and 35-inch tires. Chevrolet offered a snorkel as an aftermarket piece for the Colorado ZR2 Bison, and AEV sold a ZR2 Bison version with a snorkel attached. The new report claims GMC will make the elephant trunk a factory option, fitted to the driver's side this time instead of the passenger's side because of the new engine. The 35-inch tires would be a huge add-on, giving the Canyon the same kind of footprint as the Jeep Wrangler Rubicon Xtreme Recon and a couple of Ford Bronco trims. The additional two inches over the 33-inch tires on the AT4X make a big difference when the trail gets dicey. MCT says the AEV will get the same bumper as the Edition 1, which means a reduced approach angle in return for an integrated winch. The standard AT4X bumper permits a 36.9-degree approach angle, the winch-equipped Edition 1 drops that to 32.8 degrees. It's not clear which winch would hide behind that bumper, though. GMC factory fit is the Comeup Seal Slim 9.5rs rated at 9,500 pounds. AEV offers a Warn 9.5 XP-S with the same weight rating for its Colorado ZR2 Bison.  Speaking of which, since the Colorado arguably started all this, Chevy fans can expect their midsizer to acquire the same bundle as the Canyon AT4X AEV.

AEV-upgraded GMC Canyon AT4X, Chevy Colorado ZR2 appear in spy photos

As with the previous generation, it appears the 2023 Chevy Colorado ZR2 will be getting a special AEV version. Not only that, but its twin, the GMC Canyon AT4X will get one, too. And as these spy photos show, they'll have some additional off-road accessories included, as well as bigger tires. We'll start with the GMC Canyon. The first example of the truck without any camouflage is not quite fully upgraded like the camouflage vehicles. But it has one part not seen on the others: the AEV snorkel. 2023 Chevy Colorado ZR2 AEV Bison prototype View 13 Photos The two appear to be riding on larger Goodyear Wrangler Terrain MT tires. These look like 35-inch examples -- 2 inches larger than the biggest tires available on the ZR2 and AT4X. They're also mounted on beadlock capable wheels. Besides the bigger tires, both trucks also feature a new bed-mounted spare tire. It's a full-size spare, and unlike past bed-mounts, this one places the tire flush against the cab. The benefit of moving the spare to the bed is departure angle. And while this position looks a little less like how trophy trucks carry their spares, it should provide better cargo space. Rear visibility probably isn't great, though. Generalizing based on what we know about the current ZR2 Bison, the new AEV trucks will probably get unique grilles, steel bumpers, fender flares, a suspension lift and possibly even axle ratio changes. Additional options such as a winch could be offered, too. We expect the trucks will be revealed within the next year, since the base trucks have already been shown, and these are just upgraded versions of those trucks.
