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.

Europeans ask Chevy to bring Volt back to Europe

A group of French fans is asking for a jolt of support from General Motors to get the 2016 Chevrolet Volt across the pond. The Association Amperistes et Amis des Vehicules Rechargeables is running a Change.org petition that currently has 383 signatures out of a goal of 500. While the attempt is admirable, it's probably going to take a lot more than several hundred people for the model to make a return to the continent after the poor showing of the Opel Ampera – first-gen Volt's European cousin. The group's major argument for bringing a version of the second-gen Volt to Europe is that consumers need "an intermediate choice between expensive or range-limited pure electric cars and plug-in hybrids with a miserable electric range." Furthermore, such a vehicle would prod the competition to produce similarly efficient electrified models. They also lavish praise on the abilities of the Ampera for its long EV driving range. The supporters aren't entirely kind to GM in the petition, though, and claim the company excluded the original car from marketing efforts there. The Ampera actually enjoyed a strong European launch with more orders than initially expected and briefly topped the best-sellers list among EVs there. It was even named 2012 European Car of the Year. Those halcyon days didn't last long, and by 2014 sales fell off to a trickle. The waning reception caused GM's decision not to introduce a version of the new 2016 Volt there or in Australia. Related Video:

Read This: Auto Extremist advocates for Corvette as brand with multiple models [w/poll]

The 2014 Chevrolet Corvette really grinds Peter De Lorenzo's gears. Or, more accurately, the self-anointed Auto Extremist has an issue with what he sees as mismanagement of the legendary sports car by General Motors executives. In a new editorial on his website, De Lorenzo argues it's time to split Corvette off from Chevrolet to create an all-new brand, complete with a model range with at least three new takes on the sports car. Capable of fully leveraging the successes of the Corvette Racing program and brandishing the full might of GM's technical prowess, the Corvette brand would theoretically give Porsche something to sweat over.
Sure, that sounds like a party, but given GM's troubled track record when it comes to launching (let alone managing) brands, we say that's slippery slope that could just as easily end with the whole Corvette franchise in the scrap bin. Either way, the notion is certainly an interesting one. Head over to Auto Extremist to take in the full editorial, and then let us know what you think in Comments. Should GM split off its most storied nameplate?
