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.

2020 GMC Sierra Review & Buying Guide | The same but different

For the most part, the 2020 GMC Sierra 1500 and the Chevy Silverado are very close siblings. And with the more modestly equipped Sierra SLE and SLT models, choosing between the equivalent Chevy and GMC largely comes down to styling preference and whether you got a better deal at the GMC dealer. They’re almost identical twins. Almost. Because despite the shared DNA, there are differences in terms of model choice. There's no GMC equivalent to the cheaper Custom Trail Boss, for instance, but there is the high-dollar off-road-oriented AT4 that goes beyond the Chevy LT Trail Boss with more equipment and the availability of GMC's unique MultiPro tailgate and CarbonPro carbon fiber bed. Those are also available on the GMC Sierra Denali, which further differs with an adaptive suspension not offered by Chevrolet that seriously improves the ride comfort and handling composure of GM's full-size trucks. GMC therefore makes a compelling case for itself if you're willing to spend more for your truck, but having said that, the range-topping Sierras also don't go above-and-beyond in the same ways as the ritzy Ram 1500 and Ford F-150 trim levels do to provide a proper luxury truck experience. The new Duramax diesel engine at least stands out, but otherwise the Sierra doesn't offer a lot that others can't match or better (even within the GM family). What's new for 2020? CarbonPro Editions debut for the AT4 and Denali trim levels. These include the CarbonPro composite bed and a Kicker audio system in the MultiPro tailgate. The AT4 versions also gets some unique exterior trim. Mechanically, a 10-speed automatic is now paired with the drivetrain combo of 5.3-liter V8, Dynamic Fuel Management and four-wheel drive. Aiding visibility are newly available trailer tow mirrors, a bed-view camera, and a high-def 360-degree camera system with trailering elements.  What's the interior and in-car technology like? Like its Silverado sibling, the Sierra's cabin is its least compelling and competitive attribute, falling far behind the Ram 1500 and Ford F-150 in terms of quality and design. The dash is drab and frankly ugly in every trim level, but the cabin is particularly damning in the Sierra Denali. Its black vinyl "stitched" onto the black dash and some token strips of wood trim slapped onto the center console and doors just aren't enough to create the sort of high-dollar ambience truck buyers can find elsewhere.

GM considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.
