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.

2017 GMC Acadia loses 700 pounds, gains everywhere else

Ladies and gentlemen, welcome to Acadia. The 2017 version of the three-row GMC crossover has all kinds of newness. The 2017 Acadia has lost 700 pounds compared to its predecessor thanks to high-strength steels allowing redesigned parts, and the fact that it overall, the vehicle is actually smaller. Length is reduced by 7.2 inches on a wheelbase diminished by 6.4 inches, it is 3.5 inches narrower and sits 3.9 inches lower. The 2016 Acadia was 4,656 pounds, the 2017 is 3,956 pounds. GMC says it will still swallow people, but not as many: the eight-passenger option didn't make the transition, potential three-row trims permitting five-, six-, and seven-passenger configurations. While you lose space, you gain convenience with a split-folding second row featuring tilt-and-slide for both sections. The third-row seats fold flat into the cargo floor, and if the second row is folded as well, cargo capacity improves over the 2016 Acadia, 79 cubic feet compared to 70 cu-ft. A new 2.5-liter four-cylinder brings a second engine option to the spec sheet, returning an estimated 22 city miles per gallon and 28 highway mpg with the help of stop/start tech on front-wheel-drive trims. The new 3.6-liter V6 gets around 310 horsepower, a power bump of about 19 hp, and an estimated 25 highway mpg in front-wheel-drive guise. Towing capacity for that V6 goes down, though, from 5,200 on the current Acadia to an estimated 4,000 pounds. The optional Tow Vision Trailering system will make that pulling easier. Both engines are hooked to a six-speed automatic. Now we can get to its looks. Trademarks like the square, flared wheel arches, dark D-pillars, and wraparound rear side windows made the transition, everything else is new. While weight has gone down, safety's gone way up with internal changes like the splayed chassis members to confront the small-offset test. New active safety upgrades run from from three kinds of automatic braking systems to surround vision cameras, automatic high beam control, a safety alert seat, and a following distance indicator. Buyers can choose from a front-wheel drive, all-wheel drive, or All Terrain model, each with its own electronic drive selector modes. The Normal, Sport, and Trailer/Tow modes are common to the trio. The FWD gets a Snow mode, the AWD adds adaptive 4x4 and Off Road modes; on the AWD, the 2x4 mode disconnects the rear axle from the drivetrain.

A spotter's guide to Super Bowl LIV car commercials

Set to kick off on Fox at 6:30 ET on Sunday, February 2, from Hard Rock Stadium in Miami, Florida, the big game will feature the Kansas City Chiefs and the San Francisco 49ers. Throughout Super Bowl LIV, viewers will see about 50 commercials, each of which costs as much as $5.6 million per 30 seconds, according to AdWeek. Originally, there were more than 77 ad slots, so several companies could be paying well more than $10 million for a single, longer commercial. Numerous car companies have already announced their commercials, or their intentions to show commercials, during the game. Here's a roundup of the ones we know about so far. During the game on Sunday, we'll be livestreaming and adding links to the new commercials as they become available, so check back with us for that post.  Audi: E-Tron Sportback Maisie Williams has experience wearing many faces, and in Audi's Super Bowl commercial, she does her best Elsa impression. In the spot, titled "Let It Go," Williams faces the rigorous task of getting through L.A. traffic, but she's alleviated by the comfort of the Audi E-Tron Sportback electric crossover. The commercial is meant to signal the company leaving its gas past behind and moving forward to a sustainable future.  Genesis: GV80 Genesis makes its Super Bowl debut with a commercial that will show its all-new SUV, the GV80, to viewers around the world (many of which will be seeing the vehicle for the first time). The ad features Chrissy Teigen and John Legend as the purveyors of "new luxury," while "old luxury" is left for the birds. GMC: Hummer General Motors is bringing back the Hummer nameplate as a premium electric GMC truck. GM says it will have 1,000 horsepower and will be capable of going zero to 60 mph in three seconds. GM brought in NBA legend and Hummer fanboy LeBron James for the debut commercial. Hyundai: Sonata Hyundai is known for bringing in the big-time celebrities for its commercials, and 2020 is no different. A new advertisement called "Smaht Pahk" features John Krasinski, Chris Evans, and Rachel Dratch, all three of whom are from the Boston area. The trio gets into full character as they discuss the new high-tech parking feature on the redesigned 2020 Hyundai Sonata, and David Ortiz makes a cameo at the end. Even when New England isn't in the Super Bowl, New England is in the Super Bowl.
