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.

Carpool Deville aims to be the world's fastest hot tub

The world needs crazy inventors with wild dreams. While we might not long for the things that they create, their contraptions certainly make the day a little more enjoyable. Take the Carpool Deville as an example. Nobody (well, almost nobody) is asking for a hot tub fashioned from a 1969 Cadillac that is still drivable. But now that you know that such a beast exists, don't try to tell us you aren't at least intrigued.
The team behind the six-year-long project has a pretty ingenious setup worked out. The Caddy's original 472-cubic-inch (7.7-liter) V8 both provides propulsion and heats the water. The interior is entirely replaced with a watertight, fiberglass tub that includes working jets, and the controls are all done by hand.
As if just building a mobile hot tub isn't enough, the team behind the Carpool Deville plans to take it racing too. Specifically, they intend to go to the Bonneville Salt Flats later this year to make a top speed run while immersed in water at over 100 degrees. They even have a roll cage all set to install to meet the safety requirements there.

Weekly Recap: Car-pedestrian crashes remained elevated in 2014

The death of American Horror Story: Freak Show star Ben Woolf served as a reminder this week that car crashes involving pedestrians remain a problem, and a new study issued on Thursday reinforced that the situation isn't really getting better. The Governors Highway Safety Association found a slight decline, 2.8 percent, in the number of pedestrian deaths in the first six months of 2014. Fatalities dropped from 2,141 to 2,125 compared with the same period in 2013, though the association says it's a statistical wash when factoring in undercounting. Deaths are still 15-percent higher than in 2009. "The number of deaths remains relatively high and is cause for concern," wrote Allan Williams, who compiled the report and is the former chief scientist at the Insurance Institute for Highway Safety. This is the first look at data from last year, and the National Highway Traffic Safety Administration will issue its full-year results later. The GHSA found some progress on the roadways, as 24 states and the District of Columbia reported drops in pedestrian deaths. In some states, the problem isn't even a problem at all: Nebraska and Wyoming reported one fatality apiece, though large population centers in urban areas are where most accidents occur. "This is a clearly a good news, bad news scenario," Jonathan Adkins, GHSA executive director, said in a statement. "While we're encouraged that pedestrian fatalities haven't increased over the past two years, progress has been slow." Other News & Notes Cadillac previews CT6 during Oscars Cadillac previewed its upcoming flagship sedan, the CT6, in commercials that aired Sunday during the Oscars. As expected, the creased sedan carries on Cadillac's recent design language, and the car in the commercial looks like a larger version of the CTS and ATS sedans. The CT6 will be revealed this spring at the New York Auto Show and launch late this year. It will be assembled at General Motors' Detroit-Hamtramck factory on a rear-wheel-drive chassis, and the CT6 is the first car to use Cadillac's revised alpha-numeric naming scheme. The commercials also kicked off Cadillac's "Dare Greatly" campaign, which is the first with its new advertising agency, Publicis Worldwide.
