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.

Chevrolet To Oversee Restoring Sinkhole Corvettes

What Mother Earth devoured, Chevrolet plans to resurrect. The carmaker said Thursday it will oversee restoration of the classic cars swallowed by a huge sinkhole beneath the National Corvette Museum in Kentucky. General Motors Design in Warren, Mich., will manage the painstaking work to repair the eight prize vehicles, the automaker said Thursday. The cars were consumed when the earth opened up early Wednesday beneath a display area when the museum in Bowling Green, Ky., was closed. No injuries were reported. The museum was open Thursday except for the area where the sinkhole occurred. Mark Reuss, GM's head of global product development, said the damaged vehicles rank as "some of the most significant in automotive history." "There can only be one 1-millionth Corvette ever built," he said, referring to one of the damaged cars. "We want to ensure as many of the damaged cars are restored as possible so fans from around the world can enjoy them." Just how the cars will be pulled out of the ground remains to be seen, said museum executive director Wendell Strode. The local fire department estimated the hole is about 40 feet across and 25 to 30 feet deep. The hole opened beneath part of the museum's domed section. "We feel pretty confident that most of the cars can be extracted," Strode said Thursday. "And we hope and believe that with just a little bit of luck, that all eight cars can be extracted and be part of the restoration." Chevrolet spokesman Monte Doran said some of the cars look to be in good shape, while others are buried in rubble. "It will likely be several weeks until we can get the cars out and assessed," he said. The GM Design team has helped restore other historic cars, but the Corvette project looks to be its biggest, he said. "These Corvettes are part of our history, and they want them restored properly," Strode said. "We're thrilled they're doing this." The cars looked like toys as they plunged into the hole, piled in a heap amid dirt and concrete fragments. The museum owns six of the cars while two - a 1993 ZR-1 Spyder and a 2009 ZR1 Blue Devil - are on loan from General Motors. The other cars damaged were a 1962 black Corvette, a 1984 PPG Pace Car, a 1992 White 1 Millionth Corvette, a 1993 Ruby Red 40th Anniversary Corvette, a 2001 Mallett Hammer Z06 Corvette and a 2009 white 1.5 Millionth Corvette. Pictures of the sinkhole showed a collapsed section of floor with multiple cars visible inside the hole.

2016 Chevy Volt will not need premium gas

Buried in the new technical details of the 2016 Chevy Volt released yesterday was a throwaway line about a small but important change that's due to the new 1.5-liter, four-cylinder engine. The first-gen Volt has always required premium gas but the new powerplant will be happy burning plain old regular. The Volt's chief engineer, Andrew Farah, told AutoblogGreen that the change was due to today's Volt owners explaining they were not happy paying for top-shelf petroleum. "The ability to use regular unleaded was based directly on customer feedback," he said. "Since the range extender is an all-new engine, it was optimized to use regular unleaded at the outset. Using regular fuel will not have effect on vehicle acceleration or other performance factors." As Larry Nitz, GM's executive director of vehicle electrification, told AutoblogGreen yesterday, the new engine is more powerful and quieter than the outgoing 1.4-liter engine that's used in the current Volt. Fuel economy and EV range specs for the next-gen Volt are not expected until the full car is revealed at the Detroit Auto Show in January.
