GM files for Z71 Trail Boss trademark

Try as they might to keep their plans a secret, automakers have their hands tipped through a variety of methods – be they through loose lips, spy shots or patent and trademark applications. That's how we know, in this instance, that General Motors is working on (or at least considering) an off-road machine wearing the name Z71 Trail Boss – the name which our compatriots at AutoGuide.com tell us that GM has registered for use on light-duty trucks. Now if that alphanumeric designator sounds familiar, it should. GM has long used it to designate the off-road packages on many of its body-on-frame trucks from Chevy and GMC. These days you can order a Z71 package on the Chevy Colorado, Silverado, Tahoe and Suburban and on the GMC Canyon, Sierra and Yukon. The package typically includes components like a beefed-up suspension bits, high-capacity air cleaner and underbody protection plates. The Trail Boss designator would seem to suggest something further reaching than a suspension package, though. Just what it would entail we don't know; minds immediately start running toward Chevy or GMC going after the Ford F-150 Raptor, but we'll likely be looking at something closer to the Trailhawk packages Jeep offers on the likes of the Renegade and Cherokee.

Recharge Wrap-up: Toyota FCV Rally Car To Compete, Barra bullish on Chevy Volt

The Toyota FCV will compete in the last stage of the 2014 Japanese Rally Championship. The sport-tuned hydrogen-powered car will tackle the 177-mile Shinshiro Rally on November 1 and 2, emitting no greenhouse gases in the process. The rally course will help prove the safety of the vehicle before it goes on sale in Japan in the next several months. The Toyota FCV, rumored to be called "Mirai" in Japan, will begin sales there before April, according to Toyota, and in the summer in the US and Europe. Read more in the press release below. Carsharing is becoming more popular, and more visible, throughout the world, including the US. According to WardsAuto columnist John McElroy, 18 percent of US drivers have used some sort of carsharing service. Additionally, he says 60 percent of Americans are familiar with Zipcar and Uber. Mercedes' Harald Kroeger says promotions like free parking for carshares in Stuttgart are encouraging growth for Daimler's carsharing service, Car2go. Read more at WardsAuto. Ethanol is being help up by rail transport, according to ethanol producer Green Plains. More and more stations are carrying E15 blend gasoline, but grain producers have complained that crude oil is given higher priority by the rail lines shipping it, which rail companies deny. Union Pacific and BNSF Railway say they are stepping up service to make sure that ethanol can be shipped reliably to customers. Read more at Omaha World-Herald. General Motors "has placed a significant bet [on] the electrification of the automobile," says CEO Mary Barra. In a speech to the Detroit Economic Club this week, she spoke about the Chevrolet Volt, and its importance to GM's future. While Barra admits the Volt's success has been "not everything we wanted," it has provided experience, and shows that EVs have "an important role in the future of GM." The new Volt is more refined, stores more energy, has longer range, uses less fuel and is a big investment for Michigan. She announced that the new Volt's electric drive system will be built in Warren, and that all of its major components will be made in Michigan. "Silicon Valley doesn't have a corner on the market for innovation, creativity and drive," says Barra. "These qualities exist here – in this region – as well."

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.
