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.

Timely hole-in-one wins high schooler a Cadillac or $50,000

If it happens at all, many golfers knock in hole-in-ones in the quiet of a mediocre local course while three friends sit in their carts drinking Coors Lights. After dreaming of the moment for years, lucky golfers barely have time to process the tremendous achievement before it's followed up with a double bogey on the next hole. That wasn't the case for high schooler Jack Kyger, who drilled an ace during a golf outing, and in turn, won a Cadillac or $50,000. Kyger, a junior at Harper Creek High School in Battle Creek, Mich., says he wasn't even considering a hole-in-one when he stepped up to the tee on the fourth hole at the Battle Creek Country Club. A secondary prize, a TV, would be awarded to the golfer who came closest to the pin, so Kyger was simply trying to get it close to the cup. In front of his dad and Harper Creek Superintendent Rob Ridgeway, he stuck the shot just past the hole, and with some backspin, it rolled into the pin. It's the first time somebody has hit the bullseye at the Gene Lewis Hughes, Sr. Memorial Golf Outing, which has raised more than $150,000 for the Bronson Battle Creek Cancer Care Center throughout the years. By hitting a hole-in-one, Kyger won a $50,000 decision: take home a Cadillac or a big bag of $50,000 in cash. As a student preparing to go to college, it's not an easy choice. "I haven't made up my mind," Kyger said in a USA Today article. "But the way I think about it, no 17-year-old needs a brand new Cadillac to drive around in. I have a truck that gets me places. So, if I take the cash, I would probably put most of it away for college, but keep a little back to have a bit of fun, you know." Smart kid. We did notice a peculiarity about the prize. In the attached photo, the Cadillac at the event appears to be a Cadillac ATS-V. Those familiar with Cadillac's performance vehicles know that an ATS-V starts at significantly more than $50,000 - $68,790 to be exact. So we're not sure why they're calling it a $50,000 Cadillac, unless it's a lightly used vehicle or the Cadillac in question is in fact a different car entirely. No matter the price, it sounds like Kyger is going to take the cash. If he sticks to practicing his golf game, maybe he can earn some more money for college, too.

2014 Cadillac CTS Vsport [w/video]

Bridging The Gap With Power And Poise
As you read these words, West Coast Editor Michael Harley is preparing to drive the brand-new 2014 Cadillac CTS along the gorgeous, sun-drenched roads of Southern California. And while I'll wait for Harley's full report before I put words in his mouth, I'm willing to bet he enjoys the hell out of Cadillac's new CTS. In fact, I'm sure of it.
I say this with confidence because, about a month ago, I spent the better part of a day flogging the new CTS Vsport around the 2.9-mile Milford Road Course - a challenging circuit laid out in the infield of an oval test track at GM's proving grounds in southeast Michigan. The MRC was built about a decade ago after Bob Lutz was lured out of retirement to work closely with GM's product development team, and thus, this circuit is known informally as the "Lutz Ring." The main objective of the MRC was to have an in-house facility for engineers to fine-tune vehicle dynamics, without having to constantly schlep cars over to Germany's infamous Nürburgring. (Of course, they still do.)
