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.

Fewer than 1 in 3 Chevy dealers earn right to initially sell C7 Corvette

Looking to make the launch of the 2014 Corvette Stingray as efficient as possible, Chevrolet will be limiting the numbers of its dealers that can sell the all-new coupe and convertible. According to Automotive News, sales of the C7 Corvette will initially be limited to less than a third of Chevy's total dealership network when the 'Vette goes on sale this summer.
Only 900 dealers out of more than 3,000 locations nationwide will be allowed to sell the new Corvette at first, and the reason for this is so that there are no shortages at dealers that can actually get the cars sold. The article says that the 900 dealerships chosen represented 80 percent of total Corvette sales in 2012.
Some of the requirements dealers had to make to get initial allocation of Stingray sales include having sold at least four Corvettes in 2012 and having a Corvette Stingray specialist who will be required to have gone through a training session costing more than $2,000 per attendee. Once demand for the 2014 Corvette Stingray begins to subside - approximately six to nine months after it goes on sale - then allocation could open up to more dealers, but the report indicates this could happen following the 2014 model year.

Cadillac Celestiq, Lyriq, Hummer, other future GM electric cars: Here's everything we saw at ‘EV Day’

WARREN, Mich. — Today, General Motors held an “EV Day” event at its Warren, Michigan, campus to present its new “Ultium” battery technology, modular electric vehicle architecture and soon-to-come electric vehicles. Unfortunately, we were forbidden from bringing cameras into the event, so while we canÂ’t show you what we saw, we can tell you more about it. While we saw the previously teased Cadillac EV (which we now know to be called the Lyriq) and the GMC Hummer pickup teased during the Super Bowl, there were a number of other future cars at the event, which GM President Mark Reuss assured us are all real vehicles in the works. The biggest surprise came at the end of the event, though, in the Cadillac Celestiq electric sedan, which Reuss described as a future flagship that would be hand-built “very locally.” It had been hiding under a dark sheet all morning, with the front and rear illuminated Cadillac emblems shining from underneath. When the wraps came off, we saw a long, white, four-seat fastback sedan. The 23-inch wheels were pushed out to the very corners of the car, giving it what appeared to be a very long wheelbase. The model on the stage had no side mirrors or visible door handles. The grille mirrored that of the Lyriq crossover next to it, with integrated lighting in lieu of the usual mesh or slats youÂ’d see in an internal combustion car. The entire roof, all the way until it tapered to the tail of the vehicle, was tinted glass. In back, vertical tail lighting ran down the C-pillar before turning rearward across the top of the trunk. Inside, everything below the beltline of the windows — essentially all but the headrests and top portion of the steering wheel, was hidden from view. Behind the Celestiq, a large digital display showed a rendering of its interior. The dash consists of a pillar-to-pillar curved LED display serving as both instrument panel and infotainment system. Protruding forward between the front seats was another touchscreen that appeared to house some more controls, with open area, probably for storage, below it. The rear seats had the same sort of touchscreen between them. Built into the back of the front seats were a pair of rear-seat entertainment screens, much like we saw in the Lyriq. The door panels blended wood, metal and animated lighting to give character and a sense of opulence. GM interior design manager Tristan Murphy was on hand to tell us a bit more about the Celestiq.
