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.

NHTSA could add 1M cars to GM recall

The Detroit Free Press is reporting that the National Highway Traffic Safety Administration may expand a recall campaign for faulty brake lamps. The agency is currently looking into complaints that certain 2004-2011 Chevrolet Malibu models as well as some 2007-2009 Saturn Aura sedans may have brake lights that do not illuminate when the driver presses the pedal. Alternatively, the lamps may also illuminate without input from the driver. General Motors recalled 8,000 Pontiac G6 models from the 2005 model year for the same problem, and NHTSA is currently investigating whether to add 550,000 more G6 models built between 2005 and 2009 to the list for the same issue.
In addition, investigators are currently examining 97 complaints from Malibu and Aura owners with the same trouble. If NHTSA adds those models to the recall campaign, more than one million units could be covered. GM, meanwhile, says there have been no accidents or injuries as a result of the problem.

Junkyard Gem: 1980 Chevrolet LUV Mikado

During the 1970s and into the 1980s, each member of the Detroit Big Three imported Japanese small pickups and sold them with Ford (Mazda Proceed), Dodge/Plymouth (Mitsubishi Forte), or Chevrolet (Isuzu Faster) badges here. Ford developed the Ranger and killed the Courier for 1983 (though Americans could still buy the Mazda-badged version all the way through 1993), while The General axed the LUV after the S-10 debuted in the 1982 model year. Isuzu sold the same truck as the P'up through 1987, though, and we might as well follow up our recent P'up Junkyard Gem with its LUV predecessor. LUV stood for Light Utility Vehicle, and I've managed to spot a handful in the boneyards over the years. This one now resides in a yard in northeastern Colorado. The Mikado trim package included striped seat upholstery and a sporty steering wheel, plus these cool dash badges. As far as I can tell, no LUV Mikado advertising featured any Gilbert and Sullivan tunes. This one is fairly rusty for Front Range Colorado, and it has endured a bed swap from some other small truck. The engine is the 75-horse Isuzu 1.8-liter. Members of this engine family went into everything from Chevy Chevettes to Isuzu Troopers in the United States. Very unusually for a small pickup during the Malaise Era, this one has a luxurious automatic transmission. Acceleration must have been a leisurely affair in this truck. Air conditioning? Unheard of! Someone stuck every one of their lunchtime apple stickers on the driver's door. After 41 years of work, this truck is done. Come on strong in a LUV of your own!
