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 puts 3 million miles on hydrogen fuel cell test fleet

Have General Motors' hydrogen fuel-cell vehicles emitted enough water vapor over the past six-plus years to equal the steam coming out of Old Faithful? Not exactly, but GM has released a few figures related to the Project Driveway initiative it began in 2007. The numbers are impressive, if not quite of the geyser-spouting variety. In all, the General converted 119 Chevrolet Equinox SUVs to run on hydrogen, and those vehicles have just collectively surpassed the 3 million mile mark. And if you were waiting for us to tell you that the distance equals a half-dozen round trips between the earth and the moon, well, there you go. The better news is that the SUVs have combined to save almost 158,000 gallons worth of gas, and some of the vehicles have more than 120,000 miles on them. More than 5,000 drivers have participated in the project. GM reached that landmark about 10 months after it announced that it was working with Honda to accelerate the development of hydrogen fuel-cell powertrain technology. The two companies estimated last summer that it may have something to sell to the public as soon as 2020. For now, you can check out General Motors' press release below. GM Fuel Cell Fleet Tops 3 Million Miles Chevrolet Equinox fuel cell vehicles driven in real world reach milestone DETROIT – General Motors' fleet of fuel cell vehicles recently passed 3 million miles of hydrogen-powered, real-world driving. Some individual vehicles have accumulated more than 120,000 miles. By GM's estimate, using hydrogen to power these vehicles, the fleet has avoided 157,894 gallons of gasoline consumption. This specially equipped fleet of Chevrolet Equinox Fuel Cell vehicles are part of GM's 119-vehicle Project Driveway program, which launched in 2007. Since then, more than 5,000 drivers have provided feedback on the functionality and drivability of fuel cell technology. "Hydrogen fuel cell technology is an important part of GM's advanced propulsion portfolio and we continue to make substantial progress in furthering this technology," said Charlie Freese, executive director of GM's global fuel cell engineering activities. "These vehicles have operated through seven full winters and a wide range of environmental conditions, proving that fuel cells can meet the demands of real-world drivers." Last year, GM announced two fuel cell-related collaborations.

Recharge Wrap-up: Chevy Volt CarPlay video, Tesla Supercharger importance

A video demonstrates Apple CarPlay on the touch display in the next-generation Chevrolet Volt. The Volt's eight-inch (bigger than an iPad Mini) capacitive display is capable of putting Siri and your iPhone apps and right at your fingertips. It's "the best CarPlay display I've seen," says the user in the video. In case you're not in the market for a new Volt, 9to5Mac offers some of its favorite aftermarket CarPlay screens.

Teslarati's Electric Jen talks about purchasing a Model S, being assured by both Tesla employees and the map of planned Supercharger sites that one would be built along an important route for her. With the construction being pushed back, it made visiting family tricky. "As if owning such a grand car isn't embarrassing enough, asking for a ride to drop off and pick up said car because you can't make it home without charging really made me feel awkward," she says. "You see, one single charging location can mean the world to some people," Jen adds. Read the whole article at Teslarati. Tesla once had considered creating mobile range extender trailers for the Model S. Elon Musk touched upon the abandoned idea during his visit to Paris. While Tesla ultimately dismissed the concept, Nomadic Power has taken the opportunity to hitch their product onto the Tesla brand. "We are delighted, that Tesla Motors' CEO Elon Musk is thinking about a concept like ours for even more extending the range of the Tesla models," says Nomadic Power's CEO Manfred Baumgaertner. He adds, "This confirms our approach to build a long distance mobility provider for all electric vehicles on the market." If you say so, Baumgaertner.

When the batteries have degraded to the point that they're no longer suitable for use on the road, they still have a significant capacity that can be used for other purposes. Still useful for stationary storage, they can be used to support charging sites in order to allow for faster charging. The stationary batteries can charge slowly at the site, but then offer up the juice in a hurry when it's needed for a vehicle. Read more from Renault.
