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.

Battery Show 2015: Genovation GXE Corvette EV designed for the 'Ring

The Genovation GXE all-electric Corvette has broken cover. At the Battery Show 2015 in Novi, MI, this week, the converted C6 Z06 Corvette that we first heard about back in August was tucked into a booth along the back wall. Don't let the demure location fool you. This is a muscle-y electric vehicle, ready to roar into the limited-run, expensive EV game. The Genovation GXE Corvette can go from 0-60 miles per hour in three seconds and has a top speed of 200 mph. The powertrain was designed and built in the US, and offers over 700 horsepower and over 600 pound-feet or torque. With a near 50/50 weight distribution, this is "a real driver's car," Genovation CEO Andrew Saul told AutoblogGreen. Saul said that the GXE was designed to do two hard laps at Nurburgring thanks to a 44-kWh battery pack uses the same sort of cylindrical 18650 cells that you can find in a Tesla. That translates to about 40-50 miles of fast, on-road driving, Saul said, or 150 miles on the New York City test cycle. That particular test, "simulates low speed urban driving with frequent stops," according to DieselNet. The car also has a 6-kW charger and a six-speed manual transmission and the adjustable regenerative braking levels can be controlled by paddles on the steering wheel. Of course, none of those performance figures have been proven yet because the GXE hasn't had a chance to hit the road. Saul said that it will take another three-to-four weeks to finish the build and then, finally, there will be a few weeks of road testing. This will include a quarter-mile run on a track as well as a trip to Nevada to do a several-mile top speed test. If all of that sounds like something you're interested in, then get ready to open your wallet wide and wait. Saul said that buying one will set you back $330,000 (just $290,000 if you bring your own C6 Z06). Genovation also won't be making all that many. Saul said he expects to put the GXE into limited production of under 200 units, starting off at maybe five or 10 a year.
