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.

GM promises to add 20 EVs and fuel-cell cars to lineup, paid for by SUVs

DETROIT — General Motors outlined plans on Monday to add 20 new battery electric and fuel-cell vehicles to its global product lineup by 2023, financed by robust profits from sales of gasoline-fueled trucks and sport utility vehicles in the United States and China. "General Motors believes in an all-electric future," GM global product development chief Mark Reuss said on Monday during a briefing at the company's suburban Detroit technical center. Future generations of GM electric vehicles "will be profitable," Reuss said, but added it was not clear when GM could make all its new vehicle offerings zero-emission electric cars. Regulators in China and some European countries have floated proposals to ban internal combustion engines by 2030 or 2040. "We will continue to make sure our internal combustion engines will get more and more efficient," Reuss said. GM shares were up more than 4 percent in midday New York trading on positive comments from Rod Lache, auto analyst at Deutsche Bank. Automakers, including electric vehicle market leader Tesla, lose money on electric cars because battery costs are still higher than comparable internal combustion engines. The company offered sneak peeks of three EV prototypes: a Buick SUV, a sporty Cadillac wagon and a futuristic pod car wearing a Bolt badge. GM funds its forays into new technology using a river of cash generated by old-technology vehicles popular with its core customer base in the United States heartland. In comparison, Tesla has burned through an estimated $10 billion in cash and has yet to show a full year profit. GM earned more than 90 percent of its $12.5 billion in pretax profits last year in North America, amid robust demand for its lineup of large sport utility vehicles and pickup trucks. The company's profitable operations in China rely on consumer demand for an expanding lineup of gasoline powered SUVs. GM has previously announced plans to make some of its future electric vehicles capable of driving themselves in robot taxi fleets. The company offered sneak peeks of three electric vehicle prototypes: a Buick brand sport utility vehicle, a sporty Cadillac wagon and a futuristic pod car wearing a Bolt badge. GM collaborated with Korean battery maker LG Chem to build the Bolt battery system. Company officials did not say what companies would supply batteries for the larger fleet of vehicles promised by 2023. Fuel-cell vehicles will also play a role in GM's future, the company said.
