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 First Drive

We're in the midst of the Second Great CUV War, and the crossovers are winning by a lot. Compact sedans are being hauled around the side of idled factories and unceremoniously shot. FCA, whose be-sweatered CEO is either omnipotent or a troll of the highest order, is organizing a last stand around profit-dense SUVs and trucks on the off chance that gas prices don't rise ever again. It's the tall wagon's finest hour, and GMC is hoping the new Acadia will capture a share of the glory. The old Lambda-platform Acadia was introduced in 2007, leading the full-size, three-row crossover charge that spawned a quartet of semi-indistinct variants, including a Saturn. (Remember Saturn?) These four were truck-like in heft and capabilities, but lighter and better-mannered than their body-on-frame counterparts – and with an unusually stout 5,000-pound towing capacity. The Lambda siblings bombarded established beachheads on the sales territories occupied by minivans and truck-based SUVs. Last year, GMC moved nearly 100,000 Acadias in the US, the best year ever for the model. Now GMC shows up with a deflated Acadia for 2017, 7.2 inches shorter overall, 3.5 inches narrower, and with a 6.4-inch-shorter wheelbase. The company has even carved something like 700 pounds out of its previously portly unibody, mostly due to the size reduction but also through an increase in the percentage of high-strength steel and the use of lighter soundproofing materials. GM's C1XX platform was launched with the Cadillac XT5 earlier this year, and this GMC version is the second to appear. There's even an available four-banger, but more on that in a bit. What remains to be seen is whether the downsized Acadia represents a leaner, meaner fighter or if GMC is sending it into battle hamstrung. Outside, the new Acadia is stealthily innocuous. Gone is some of the lozenge-ness of the outgoing Acadia, but don't fret about it standing out from the crowd. The overall styling falls into lockstep with the Sierra and Canyon. The cut of the rear window, with an upsweep at the trailing edge, emulates the brand's mid-sized truck offering. A chrome mustache cuts across the front fascia below the grille, and there's more brightwork around the front side windows and at the crease below the scallop in the doors. The taillights are more contemporary than before, with an attractive elongated C element comprised of LEDs.
