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.

2015 Cadillac Escalade

Cadillac has been an interesting story in the auto industry over the past several years. Its comeback bid may be well over a decade old, but it's only recently that the Wreath and Crest has transformed from the auto industry's retirement home into its hot new thing. Today's Cadillac is a powerful marque working to instill passionate design, sound driving dynamics and cutting-edge technology into each model it builds, with vehicles like the ATS and redesigned CTS leading the charge.
Now, its latest model has arrived. This fourth-generation Escalade is among the most important new Cadillacs since the division's renaissance kicked into high gear. It's the brand's de facto flagship, and the first vehicle many young people think of when hearing the name "Cadillac." In the past, the Escalade was the chosen vehicle of the rich, flashy and famous. It's suffered over the past few years, though, particularly as new and more luxurious competitors have come to the fore.
With this latest redesign, General Motors is aiming to retake the spotlight as purveyors of the market's premier luxury SUV. To find out if it's been successful, I ventured down to the South Carolina Lowcountry to test the all-new 2015 Escalade.

2015 Cadillac Escalade

I have never liked traveling to Monterey, CA. The picturesque coastal city is about 300 miles from my home in Los Angeles, which means cramped and uncomfortable regional aircraft are part of the equation when the turnaround is only one night. Over the years, I have cursed the LA Basin's bumper-to-bumper traffic en route to the airport, argued with TSA personnel over carry-on baggage and waited countless hours for the fog to lift just for the anguish of being packed into a small regional jet for the flight. Of course, the process repeats on the trip home with equal misery.
Yet this time I am not suffering.
Cadillac has dropped its all-new 2015 Escalade in my driveway. Instead of battling city congestion, attempting to reason with misinformed government agents, snacking on a too-small bag of pretzels and physically rubbing shoulders with a dubious stranger for 90-plus minutes within the confines of a bumpy aircraft, I have chosen to forgo air travel and drive myself door-to-door in a fullsize luxury sport utility vehicle.
