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 XT4 crossover reveals its lighting

The upcoming Cadillac XT4 compact crossover has once again been spotted, this time with less camouflage and an update to its lighting. Specifically, the little crossover is sporting production lighting front and rear, and it's sure to make the luxury SUV one of the boldest-looking Cadillacs. Part of the reason for this comes from the taillights. As we suspected from the last set of spy shots, the XT4 will have highly distinctive lights that run the full height of the C-pillar. Though it's a similar design to that of the Escalade, it's made more interesting by the significant forward rake of the rear pillar. Not only that, but that pillar is quite thick, too. The look is actually reminiscent of the old CTS wagon. Moving around the side, the reduced camouflage reveals that the doors and quarter panels are fairly conservative and lacking in many creases or bulges. We can make out the edges of what will likely be black plastic fender flares and rocker panel cladding. Finally reaching the front, we see that the headlights are similar to those of many current Cadillacs, including the recently refreshed XTS sedan. The main part of the lamp starts high up and is slightly horizontal like the Escala concept, but they extend over the fenders and a strip of LEDs descends down the front. A previous report noted the XT4 will be built in Kansas on the Chevy Malibu platform. That means it will be a front-drive-based vehicle likely offering both front- and all-wheel-drive. Under the hood will probably be at least one turbocharged four-cylinder engine, with a second, more powerful upgrade option a possibility. We expect to see the fully revealed model to show up by the end of 2018.

Cadillac scraps three-row CUV plans

Crossovers are one of the hottest automotive segments on the planet. Apparently, the idea of mixing the practicality of a station wagon with the looks of an SUV appeals to people whether they are in Cleveland or Shanghai because nearly every automaker is jumping into the market. So it was no surprise when early rumors suggested Cadillac was planning two, new CUVs to fit above and below the SRX. But things might have changed since then.
New rumblings indicate Caddy is taking a different route. Instead of two crossovers, only the compact is on the way, and the larger, three-row CUV on the Lambda platform to sit between the SRX and Escalade may be a goner. According to Ward's Auto, General Motors thinks that the other three-row, Lambda vehicles like the Buick Enclave and GMC Acadia compete too closely with the proposed Cadillac. The decision comes fairly close to the 2017 intended production date.
As far back as 2010, this Lambda-platform based CUV was considered highly likely for production. However, Cadillac Senior Vice President Bob Ferguson was somewhat cooler about it when he discussed the new crossover briefly last year. He said the model could use the Escalade name, despite its unibody chassis, but no decision had been made yet to actually produce it.
