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.

Cadillac V-Performance Academy joins free driving school party

Just in case you needed another reason to want one of Cadillac's hottest performers, starting with the 2017 Cadillac CTS-V and ATS-V, the first owner of each vehicle can score a free two-day course at Spring Mountain Motor Resort with the V-Performance Academy. According to Spring Mountain's website, the V-Performance Academy "is designed for drivers of all experience levels and includes dynamic car control exercises, visual skill development, and proper cornering techniques," with "brief" classroom sessions sprinkled in. Driving programs like the V-Performance Academy are all the rage right now. In the last few weeks alone, both Fiat and Ford announced free one-day academies baked right into the price of cars like the 124 Abarth and Focus RS. As with the Ford and Fiat courses, Cadillac is providing the learner cars. But where those other courses call on vehicle owners to shell out for airfare, food, and in Fiat's case, lodging, Cadillac covers tuition – a $2,420 expense for non-owners – along with two nights in one of Spring Mountain's "luxury condominiums" and breakfast and lunch during both driving days. Students are still on the hook for airfare, although Caddy will shuttled attendees from Las Vegas McCarren to the track/resort, some 55 miles away. If you can't shell out for the flight to Las Vegas, a new CTS-V or ATS-V, or simply can't spare two days for a driving school, Cadillac is ramping up for another year of its one-day, traveling V-Performance Lab, which will run at Lime Rock Park in Connecticut and at Circuit of the Americas in Texas.

Cadillac LTS flagship to bow at NY Auto Show

There is widespread agreement across the industry that Cadillac needs a proper, rear-drive flagship sedan that completes legitimately with the Mercedes-Benz S-Class, Audi A8 and BMW 7 Series.
Fortunately, the same view is held within the company, and just such a car - possibly dubbed LTS - is under development. According to a high-level source at Cadillac, the new four-door, which is said to incorporate design cues from the marque's celebrated Elmiraj coupe concept, will debut at the New York Auto Show next April.
If the car needs a cheerleader, surely incoming president Johan de Nysschen is just such a person. De Nysschen doesn't arrive at Cadillac until late in the month, but certainly he will want a proper flagship to do battle with his old foes at Mercedes-Benz and BMW and old friends at Audi and Infiniti.
