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.

Consumer Reports loves the 2014 Cadillac CTS

Our first drive of the 2014 Cadillac CTS was just published today... we really liked the Vsport version. And Consumer Reports has some even stronger words of praise for the all-new luxury sedan. We already knew that Cadillac had stepped up its game with the third-gen CTS, but CR bluntly states that the sedan drives better than its German luxury counterparts.
While CR shows plenty of love for the new CTS, the outlet still takes issue with some of the in-car technology including the CUE infotainment system - no surprise there. The testers' offer all manner of positive comments where the impressive handling capabilities of the sedan are concerned, with lots of drifting around CR's private test facility in evidence to bear them out. Scroll down to watch the CTS get put through its paces.

Cadillac could 'flourish' in Australia, says marketing chief

Cadillac might have its best product mix in recent history, and GM's luxury brand is looking to expand. In fact, it might even be making a trip Down Under, at least according to the company's global marketing chief.
Uwe Ellinghaus spoke with Australian site Car Advice at the Geneva Motor Show and said the brand could be quite successful there. "[The] goodwill that the Cadillac brand has is such a good starting base that once we get proper volume commitment and a dealer network behind it we can easily flourish," he said, though he warned that the plans are still in their earliest stages and years away. First, Cadillac will expand in markets with the highest possible sales, like China and Russia.
Ellinghaus said that the most likely models for Oz would be the SRX, Escalade and CTS; the latter would probably act as a replacement for the Holden Commodore. GM's Australian arm is ending local production in 2017, and there have been many rumors about what is happening to the big sedan. However, Ellinghaus admits exporting cars from the US to Australia is going to mean higher prices. In addition to the expense, Cadillac doesn't currently build any right-hand-drive models. It would likely take until the end of the decade before the Aussie models could be ready.
