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 developing stretched ATS-L just for China

To luxury automakers, long-wheelbase sedans are to China that crossovers and SUVs are to the US, so it isn't all that surprising any more when the latest sedan gets an extra couple of inches between the wheels to improve rear-seat comfort. According to Car News China, the next sedan to get the stretch will be the Cadillac ATS, which will increase the wheelbase by 10 centimeters (about four inches) to become the ATS-L.
Designed to go up against rivals like the BMW 335Li and the added-length Mercedes C-Class, the ATS-L will reportedly be built locally in China with an engine list that will grow as well. Currently, only the 2.0-liter turbo engine is offered in the ATS in China, but the ATS-L will get the full spectrum of ATS engines including the base 2.5-liter and the peppier 3.6-liter V6. This isn't the first time Cadillac has offered a China-specific stretched sedan either as the SLS dates back to 2006.

These are the top luxury cars bought by people entering the segment for the first time

Let's say you just got a big promotion at work or the kids are moving out of the house, and you finally have some extra money. You decide to blow it all at once and treat yourself by upgrading your ride. Naturally, you look to a luxury automaker. What do you choose?
Models like the Audi A3 and Mercedes-Benz CLA-Class may be tailor-made to introduce buyers to the premium segment, but a new study finds that they don't garner the highest rates of non-luxury customer conquests. It turns out that a Volvo leads among folks moving up to a premium brand, and it isn't even one that's made anymore, at that.
A recent study by Polk and IHS Automotive looked at what models had the highest rates of buyers upgrading from a non-luxury segment. The information comes from its new vehicle registration data through April 2014. All ten top models boasted conquest rates of over 50 percent, but the Volvo C70 led the field with 68.01 percent of its customers coming from non-premium brands.
