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 Heavy Duty teased, and you better believe there's a huge grille

Chevrolet has shown us a few photos of its redesigned Silverado Heavy Duty, and today we score our first teaser of the GMC Sierra version of this truck. The most controversial feature of the Silverado HD has to be its massive grille, and the Sierra appears to be no different. Just from this photo of the face, we can already tell it's going to be as bold, some might say gaudy, as the Chevy. We'll have to wait awhile to see it all, though, as GM says the Sierra HD will be making its debut in the second half of 2019. It's no Supra teaser campaign, but this one is already starting out pretty early for a work pickup truck. As far as features and technical details go, mum is the word for now. However, we can assume the Sierra will be nearly identical with the Silverado HD powertrain-wise. We know two engines will be offered on that truck, one being a gasoline V8 and the other a Duramax turbodiesel V8 — the former will be mated to a six-speed automatic, while the latter gets the 10-speed auto. Even though it isn't out yet, the torque figure is already less than the Ram and Ford heavy duty trucks at 910 pound-feet from the diesel. The Ram Heavy Duty just revealed at the Detroit Auto Show scores a whopping 1,000 pound-feet of twist in the torque department. We'll know more about the Sierra HD when the Silverado HD presumably gets revealed with full details at the 2019 Chicago Auto Show at the beginning of February. One thing's for sure: If you want chrome and lots of it, you're gonna get it with the 2020 GMC Sierra HD. 2020 Chevy Silverado HD View 5 Photos Related video: This content is hosted by a third party.

2022 GMC Sierra Preview | GM's 'premium truck' is actually now premium

Pros: Quiet and torque-rich Duramax diesel; big touchscreen on most trims; great trailering tech; versatile MultiPro tailgate Cons: Worse ride than most rivals; AT4X priced like a Raptor but doesn't go like a Raptor The 2022 GMC Sierra 1500 is GM’s upmarket half-ton pickup, with a supposed emphasis placed on interior quality and materials rather than bare-bones durability. Supposedly, at least. In reality, the most recent generation hardly lived up to that promise as it showed few upgrades over its Chevy Silverado sibling, which itself possessed a ho-hum, not-really-trying interior clearly overshadowed by Ram and Ford that at least match it in most other respects. It was particularly noticeable when comparing top trim levels. GMC's supposedly premium entry, and especially the Denali, just didn't cut it. That changes in a huge way for 2022. First, thereÂ’s not just one new and massively improved interior, there are two. The SLE, Elevation and SLT once again share their interior design with the Silverado, but that includes a more visually appealing design, better materials, smarter storage and a significant technology upgrade thanks to the standard 13.4-inch touchscreen running the user-friendly Android Automotive OS. The AT4 and Denali trim levels, including the new AT4X and Denali Ultimate, step things up even further with a different dash design and upgraded interior materials. The Ultimate definitely lives up to its name with a characterful and, yes, premium vibe that stands tall against the best of Ford and Ram. Other welcome updates include the option of Super Cruise on top trim levels and a massively more powerful base turbo four-cylinder engine (it produces more torque than the 5.3-liter V8!). Effectively, the 2022 GMC Sierra is now the truck it shouldÂ’ve been since the beginning of this current generation and definitely worth a look – especially if youÂ’re in the market for a premium truck. Now, a bit of housekeeping. While the massively updated model shown here is officially the 2022 GMC Sierra, thereÂ’s a chance you could come across something called the "2022 Sierra Limited.” That was just last year's truck with the 2022 model year stapled to it. There are many reasons for this, but suffice it to say, if you see a Â’22 Sierra Denali with the ugly robot-face dashboard (below right), youÂ’re looking at a Limited. Also, the availability of Super Cruise and other features have been hampered by supply shortages.
