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.

2020 Cadillac XT6 Review & Buying Guide | Sneaking in through the back

The 2020 Cadillac XT6 is arriving late to the party, literally decades after some of its rivals. It's a new, three-row luxury crossover that serves as a much-needed, more-modern and less ostentatious family hauler than the Escalade (which is getting overhauled next year, by the way). The question about the XT6, then, is it fashionably late? The XT6 is indeed quite handsome and refined -- we thought it looked particularly excellent in one our test car's Red Horizon Tintcoat. There's a classic sophistication to it that evokes Cadillacs of the 1960s rather than the overwrought and borderline-tacky designs of other eras (including recent ones). We think the exterior design will age quite well, especially in light of some competitors. However, we're also not sure it's distinctly a Cadillac. Worse, the interior is drab, unimaginative, and blighted with unremarkable materials. A Volvo XC90 and Lincoln Aviator instantly look and feel more special, while a range-topping Hyundai Palisade isn't as far behind as the price gap would indicate. The driving experience also leaves something to be desired. Besides the ho-hum engine, the XT6 has neither the sharp handling of Cadillac's recent sedans nor the stately ride comfort one also might expect given the brand's past. Overall, the XT6 sneaks in through the back of the party rather than making a grand entrance; an unremarkable effort in a toughly contested segment. What's new for 2020? The XT6 is an all-new model and fills a gap in Cadillac's lineup. What's the XT6's interior and in-car technology like? Answering this question is all about perspective. In a vacuum, the XT6 interior seems nicely put together, its leather is soft and features are in abundance. The range-topping trim's gold carbon fiber trim is particularly interesting. If you sat in one after a Buick Enclave, the step up would be obvious. However, come from a Lincoln Aviator or Volvo XC90, to cite two excellent examples of the breed, and the difference is stark in terms of design and materials quality (there are too many hard plastics throughout). The XT6 quite simply isn't as cool, isn't as luxurious and doesn't seem to justify its price tag. At least features content is strong with six USB ports, wireless charging, Android Auto, Apple CarPlay and satellite radio all included along with a panoramic sunroof and various driver assistance technologies. Other brands nickel-and-dime you with this sort of content.

Consumer Reports explains its disdain for infotainment

One of the perks of reviewing all manner of cars and trucks is that we're exposed to all the different infotainment systems. Whether Cadillac's CUE, Chrysler's UConnect, BMW's iDrive or MyFord Touch, we sample each and every infotainment system on the market.
Not surprisingly, some are better than others. It seems consumers have come to a similar consensus, with Consumer Reports claiming that Ford and Lincoln, Cadillac and Honda offer the worst user infotainment experiences. Not surprisingly, you won't find much argument among the Autoblog staff.
