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.

Editors' Picks February 2022 | GMC Yukon, CT4-V Blackwing and Lexus NX 450h+

The shortest month of the year spawned a few Editors' Picks choices, and they come from a variety of categories amongst the car world. One comes with a particular caveat, the Lexus NX. Specifically, the new NX that gets our nod is the 450h plug-in hybrid model. We can heartily recommend an NX in this guise for its superb electrified powertrain, but the other versions fail to stir us in the same way. Beyond this, it's some of the latest from GM cleaning up, and they sure are some good ones. In case you missed our previous Editors' Picks posts, here’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in January that earned an EditorsÂ’ Pick. 2022 GMC Yukon Quick take: The Yukon is a big, comfortable and versatile SUV that has a little something for everybody, so long as you can stomach the fuel economy. It's an excellent middle ground between the Tahoe and Escalade. Score: 8.0 What it competes with: Ford Expedition, Jeep Wagoneer and Grand Wagoneer, Lincoln Navigator, Chevrolet Tahoe, Cadillac Escalade Pros: Tons of space, comfy ride, great trim variety, powerful engine options Cons: V8 Fuel economy, infotainment can be laggy, unexciting base interiors From the editors Road Test Editor, Zac Palmer — "GM's full-size SUVs are fantastic this time around, especially if you opt for the magnetic shocks and air suspension. The availability of a diesel engine that vastly improves fuel economy is huge, and the Denali trim is more special than ever with its unique interior design. I personally prefer the Yukon's styling over the Tahoe's, too." In-depth analysis: 2022 GMC Yukon Review | AT4 and Denali make the strongest case   2022 Cadillac CT4-V Blackwing Quick take: Cadillac is at the top of the mountain with its performance sedans, and the CT4-V Blackwing is no exception. One drive in this magnificent creation will have any enthusiast convinced that it's a top-tier sport sedan.

GM lays off 450 at Lansing Grand River Assembly

General Motors will lay off 450 employees at its Lansing Grand River factory, The Detroit News reports, which is 100 more than the company said it'd be letting go last month. Lansing Grand River Assembly currently builds the Cadillac ATS and CTS, both of which have suffered sluggish sales, with the smaller sedan down 20 percent through last month and the larger model down 2.3 percent, The Detroit News reports. "We are adjusting plant production capacity to better align with market demand. Beginning in January 2015, the plant will operate on a single shift," a GM statement read, before explaining that not all the laid off Grand River employees will be jobless. Of the employees that have been laid off to make room for the single work shift, around 200 will transfer to the Lansing Delta Township factory, home of the Lambda-platform crossovers, GM's statement confirmed. The News expects this one-shift arrangement to continue until at least late next year, when the Alpha-platform Chevy Camaro transitions from General Motors' Oshawa, Ontario factory to Lansing. Cadillac President Johan de Nysschen said at last month's LA Auto Show, "It may not necessarily be permanent, a time may come when we've gained momentum and we can reinstate it. But for now, the adjustment to production capacity is in alignment with our plans for 2015."
