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.

Very first Chevy Camaro found and restored

Restoring an important classic car can lead people down rabbit hole upon rabbit hole of discovered history in a process that's essentially automotive genealogy. Take the recent rejuvenation of the very first Chevrolet Camaro as an example. The owners started with a strong hunch that the vehicle might be something special and spent years researching to figure it all out before the mechanical work even began. Fisher Body kicked off work on the first Camaro on May 17, 1966, and it was delivered to General Motors just a few days later for final assembly. While the model has earned a place as an American performance icon since then, the original was built more to develop the production process and boasted just a 230-cubic-inch (3.8-liter) inline six and 3-speed transmission. After spending its first few months appearing in promotions, a Chevy dealer in Oklahoma got the gold car in December of '66. It was touted on the sales floor there for years, and the first private owner didn't come until 1969. This short documentary goes into astonishingly comprehensive detail about every bit of the first Camaro's history. If you just want to hear the story of the latest owners and their work to get the vehicle restored since 2010, skip about 11 minutes into the video. Or, of course, you could just enjoy the whole thing. News Source: PilotCarRegistry via YouTube, Camaro NewsTip: Chris P.
