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.

Chevy Express 1500, GMC Savana 1500 get the axe

Fans of truck-based, light-duty vans can officially pour one out for the Chevrolet Express 1500 and GMC Savana 1500, as General Motors has officially put its long-serving big/little rigs out to pasture. Things aren't quite as sad as they sound, though. The heavier-duty 2500 and 3500 vans will soldier on, in order to duke it out with the largest members of Ram ProMaster, Ford Transit and Mercedes-Benz Sprinter families.
The move does seem to make a lot of sense. According to GM, customers only purchase the 1500-spec Chevrolet 23 percent of the time, while the GMC captures a mere 7 percent of the Savana family's sales. With numbers like that, it's no shock that GM thinks it can shift some of its buyers into its van family's more capable variants. "We knew we could move a lot of our 1500 customers into 2500-series territory," said GM's Joe Langhauser, the product manager for the company's full-size vans.
It's not just simple sales figures dictating the move, though. The 1500 line is taking up some valuable factory space that will be better spent on an eagerly anticipated new product.

2015 GMC Yukon erupts into flames during Anaheim test drive [w/video]

A 2015 GMC Yukon burst into flames while on a test drive in Anaheim, CA on Sunday after smoke filled the cabin. Residents of the neighborhood where the driver abandoned the redesigned Yukon reported hearing a series of small explosions (likely the tires, based on the video), according to a report from KTLA and The Los Angeles Times.
No one was injured in the incident, which The Times reports occurred after a possible oil or fluid leak. As you can see in the image above, the Yukon was engulfed in flames, although the Anaheim Fire Department was able to put out the blaze in about 15 minutes.
"We're very lucky that no one got hurt, and it was in an area that... was safe," Lt. Tim Schmidt of the Anaheim Police Department told KTLA reporters. "If there was any place that was going to be safe, it would be this area. It's very open. It worked out for us."
