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.

Lutz dishes dirt on GM in latest Autoline Detroit

Autoline Detroit recently played host to Bob Lutz, and, as is always the case, the former General Motors vice chairman dished out some great commentary. Lutz was promoting his new book Car Guys vs. Bean Counters: The Battle for the Soul of American Business, and talk quickly turned to his role as it related to product development and high-level decision making at GM. While on the topic of brand management, Lutz revealed a few rather interesting tidbits about his former employer:
All Chevrolet vehicles were required to have five-spoke aluminum wheels and a chrome band up front, as part of the Bowtie brand's overall image.

Confident new Cadillac marketing boss ready to take on Tesla, BMW

When there's a former BMW executive heading Cadillac's efforts to boost sales of its only plug-in, it's a pretty safe guess that the marketing emphasis won't be on environmental friendliness and tree-hugging tendencies. The General Motors luxury brand has appointed ex-Bimmer executive Uwe Ellinghaus to be its marketing chief late last year, and the German-born Ellinghaus is now saying that he's targeting potential customers of Tesla Motors, in addition to BMW, for potential growth in sales of the Cadillac ELR extended-range plug-in. Appointed to Cadillac's head of marketing last November, Ellinghaus recently told Advertising Age that GM needs to highlight the Cadillac's looks and performance. He complimented Tesla for putting more emphasis on those attributes in the Model S than on its lack of emissions or lack of refueling costs (but Tesla hasn't shied away from highlighting the EV's savings). Ellinghaus says that trying to gear advertising "for people who are tree-huggers and green-wash an entire brand" won't be successful. You don't say. So far, the ELR hasn't made much of a dent in US car sales. Through May, Cadillac, which spent about $280 million on all of its US marketing last year, sold 293 units, whereas Tesla had been approaching the 11,000-unit figure for the Model S. With that in mind, Cadillac may be working on a sportier version of the ELR, as spy shots of a test vehicle from May revealed larger brakes and wheels.
