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.

2018 GMC Yukon Denali gets a sculpted new grille

More than half of all GMC Yukon and Yukon XL models sold wear top-level Denali trim. That's a profitable scenario for the automaker, so, perhaps above all else, GMC needs its premium Denali series of vehicles to continue to stand out in a line of trucks and SUVs at the dealership lot. Hence, chrome, and lots of it. But for 2018, GMC is blessing the behemoth Yukon Denali with an added dose of class with a new multi-dimensional grille. "The new grille, which is flanked by HID headlamps and LED Signature Lighting, advances the design legacy established with the very first Yukon Denali in 1999," said Matt Noone, director of Global GMC Exterior Design. In addition to a sophisticated new look, the grille adds customizable cooling capabilities to the Denali range. Active shutters open when additional cooling is needed, or close to reduce aerodynamic drag when the engine isn't too warm. Further increasing the efficiency of the big brutish 'ute is a new 10-speed automatic transmission. That's two extra gears over the 2017 Yukon Denali, leading to a numerically lower final drive to help save fuel at highway speeds. Inside, Mastique Ash wood trim differentiates the 2018 model from previous years. A 420-horsepower 6.2-liter V8 engine remains standard for 2018, as do blingy 20-inch wheels with 22 inchers optional.

2022 GMC Hummer EV Drivers' Notes: We can't stop talking about Crab Walk

The 2022 GMC Hummer EV Pickup defies reason and sense in most ways. It’s a pickup that weighs over 9,000 pounds, but will do the 0-60 mph sprint in around 3.0 seconds. That sounds like something to be afraid of, but itÂ’s also something you want to experience. ItÂ’s a feat of engineering to make something so heavy move so quickly, but thatÂ’s what the EV revolution has brought upon us. GMC gets the Hummer up and moving as quickly as it does with three electric motors — one in front and two in the rear — that combine for a nutty 1,000 horsepower and 1,200 pound-feet of torque. All of that power is unleashed in Watts To Freedom (WTF) mode. Your seat starts rumbling; the air suspension lowers you to the ground, and an electrifying soundtrack is played over the speakers to match your throttle applications. Launching this supertruck is an event every single time, but due to its extra-high ride height and off-road chops, sending it down your favorite trail is, too. That is, assuming said trail is wide enough to fit the gargantuan Hummer. Those knobby all-terrain tires keep the Hummer from being even mildly entertaining when you explore the truckÂ’s handling Â… but who cares. Our specific tester is an Edition 1 model, which means it comes fully loaded with every option you can imagine. As such, its price is $110,295. For the amount of performance and capability on display here, that number sounds surprisingly right. ItÂ’s also befitting the HummerÂ’s status as a supertruck, wherein you get everything youÂ’d ever want in one go-anywhere do-anything package. Editor-in-Chief Greg Migliore — The Hummer EV is the biggest rock star vehicle IÂ’ve tested in quite some time. Literally. ItÂ’s huge and attracts a ton of deserved attention. The Hummer design is spot-on, especially the grille, lights and flared fenders. It looks the part. For $110,000, it should also have some substance, and this Edition 1 delivers Super Cruise, Watts to Freedom and CrabWalk, not to mention GMCÂ’s MultiPro tailgate and the removable Sky Panel roof. It feels quick, as you would expect something with 1,000 hp to feel, and itÂ’s shockingly maneuverable. I CrabWalked down my street to show off, navigating around things on the diagonal and amusing the neighbors. Just the regular four-wheel-steering function, which functions similar to those offered by various other cars, allows the Hummer to turn easily and confidently.
