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.

Recharge Wrap-up: Tesla sells Model S 85 and 70D in Malaysia, Chevy Spark EV built using clean energy

Tesla will send Model S 70D and Model S 85 EVs to Malaysia for leasing to government-linked companies. Only those companies will have access to the models as a two-year lease, which will be imported and leased by Malaysian Green Technology Corporation. The plan is part of an initiative by the Ministry of Energy, Green Technology and Water to allow government officials and other influential people to get to know the electric vehicles and the benefits that come along with them. Most of the 120 vehicles available will be the 70D model, and the lessee companies will have the option to purchase the cars at the end of the two years. Read more from Paul Tan's Automotive News.

Silverado HD, Touareg V10 TDI face off in diesel tug-of-war

A couple weeks ago, we watched a Chevrolet Silverado get dominated by a Dodge Ram Heavy Duty in a fullsize pickup tug-of-war, but in that truck's defense, Chevy's Vortec gas engine was no match for the torquey Cummins turbo diesel. For our next round of vehicular tug-of-war, a Duramax-powered Silverado HD takes on Volkswagen Touareg V10 TDI.
Now, on paper, putting the Duramax V8's 365 horsepower and 660 pound-feet of torque up against the V10's 310 hp and 553 lb-ft looks like an easy win for the Bowtie, but unfortunately, this battle has a similar result as the Dodge versus Chevy video, with the Silverado smoking its tires trying to move forward as it gets pulled backwards. Put another way: YouTube 2, Chevy Silverado 0.
It just goes to show, though, that big tires, bolt-on fender flares and goofy smoke stacks don't improve your towing abilities. Besides, what did the Silverado driver expect when the Touareg V10 TDI has towed a Boeing 747 in the past?
