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 introduces Canyon Nightfall Edition for the steathly and stylish

It may be just now arriving at dealers, but the 2015 GMC Canyon has just received its very first special edition trim, although the stealthy Nightfall Edition is, in the greater scheme of aesthetic upgrades, pretty basic. GMC has blacked out the truck's grille and side steps, added a spray-in bedliner as standard, fitted new 18-inch "Dark Argent" wheels with black inserts, a polished exhaust tip, remote start and automatic climate control. Naturally, the Nightfall Edition is only available with Onyx Black paint. Customers interested in the blacked-out pickup will need to choose between two-wheel drive and four-wheel drive, although they'll be freed the burden of picking a trim level or body style, as the Nightfall is limited to the mid-grade SLE with the four-door crew cab arrangement. "The new Canyon Nightfall Edition expands the Canyon lineup and gives style-conscious customers another choice," GMC's vice president of sales and marketing, Duncan Aldred, said in a statement. "Importantly, customers get the great looks of the Canyon Nightfall Edition and its unique content at a greater value than ordering the features separately." GMC has not released any information about the price of the Nightfall Edition, or when it will arrive in dealerships. Scroll down for the full press release announcing the newest member of the Canyon family.

Watch the 2022 GMC Hummer EV launch using its Watts to Freedom mode

It’s nearly the July Fourth weekend, and GM is celebrating Independence Day a little earlier than most. The celebration comes in the form of a GMC Hummer EV demonstrating Watts to Freedom, or WTF, mode for us on video. You can watch it at the top of this post, but the idea is rather simple. ItÂ’s just a video of a Hummer development vehicle accelerating as quickly as it can from 0-60 mph and beyond. GMC claims its 1,000-horsepower electric Hummer is capable of hitting the 0-60 mph mark in “approximately 3 seconds,” which is borderline terrifying for how large of a vehicle it is. The super-quick time is possible when using the Watts to Freedom launch control mode, which “channels the propulsion systemÂ’s tremendous power into acceleration bursts.” The truck will still be plenty fast when accelerating normally, but WTF mode is what you should use to unlock its full potential. GMCÂ’s video shows us the graphics it uses in the digital cluster to signal Watts to Freedom is activated, and the whole sequence looks like it leans on U.S. military themes for both design and phrasing. For example, GMC lets you know that Watts to Freedom is ready via an “Armed” message in the cluster.  The 2022 GMC HUMMER EV is a first-of-its kind supertruck develop View 40 Photos Instead of a rumbling exhaust and screeching tires, the Hummer appears to silently launch with all four tires grabbing on and catapulting the truck away. It looks quick as it throws all of the weight rearward into an accelerative squat. And in case you missed it, thatÂ’s a lot of weight — GMC says itÂ’ll tip the scale at 9,046 pounds. GMC has previously said that production will begin in late 2021, and this video continues to confirm that timeframe with a note saying “initial availability Fall 2021.” Do keep in mind that only the sold-out Launch Edition is coming at that time. Other cheaper variants will follow in the years to come. Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
