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.

Looking back at the Citation IV concept that likely shaped the GM EV1

Those who forget history are condemned to repeat it. We're not sure how that applies to the GM EV1, but we'd still like to share something from Autoline Daily, an online automotive new show with our friend John McElroy. He's been covering the business for decades now and recently found something interesting: pictures of the 1984 Chevrolet Citation IV concept, seen above. Displayed half a decade before the first electric concept that would become the EV1 (inset), McElroy says it's now clear that the elegant, aerodynamic EV1 took a lot of styling cues from the Citation IV, which was developed in part thanks to GM's new-at-the-time Aerodynamics Laboratory. We agree with him that the spats over the rear wheels, the flush glass, and the covered headlights all bear a certain kind of similarity between the two cars. That the colors almost match is a nice coincidence. The Impact (the concept version of the EV1) looked "frumpier," McElroy says, because it wasn't as long as the Citation.

2016 Chevy SS gets new face, clears throat

Chevy is tweaking the SS once again for the 2016 model year. While the changes might be minor, muscle sedan enthusiasts shouldn't need any more excuse to love the Bowtie brand's performance sedan. The 2016 Chevy SS benefits from revised front-end styling that incorporates new vertical ducts designed to direct airflow over the front wheel wells. It also gets new LED lighting and new functional hood vents to make it look even more aggressive than the current model. Although the 6.2-liter V8 carries over unchanged from the existing version – churning out 415 horsepower and an equal amount of torque – a new dual-mode exhaust promises to be both quieter at lower speeds and angrier-sounding at higher revs. And of course you can still get it with a six-speed manual or automatic transmission. In any event, it should also look the business with its new 19-inch alloys as well. Related Video: 2016 Chevrolet SS Designed for Performance DETROIT – Building on the performance-oriented updates made to the Chevrolet SS last year, the 2016 model features several exterior enhancements that reinforce its presence on the road. A revised front fascia features new, vertical ducts at the outer edges to direct airflow over the front wheel openings to improve aerodynamic efficiency. The fascia also incorporates new LED signature lighting, while new, functional hood vents and new-design 19-inch cast-aluminum wheels contribute to a stronger appearance for the rear-drive sports sedan. "The 2016 SS design changes more fully express the true driving character of the sedan while further enhancing the car's overall performance," said Todd Christensen, Chevrolet Performance Car marketing manager. What hasn't changed is the SS's unique blend of performance, comfort and spaciousness. It features a 6.2L V-8 engine under the hood and turns out an SAE-certified 415 horsepower (310 kW) and 415 lb-ft of torque (563 Nm), and offers a six-speed manual transmission or a paddle-shift six-speed automatic transmission. A new, dual-mode exhaust system for 2016 complements the V-8 engine with quieter performance at low engine speeds and a more muscular engine note at wide-open throttle.
