GM recalling 22K Silverado and Sierra trucks for seat issue

General Motors will recall 21,721 of its new 2014 Chevrolet Silverado and GMC Sierra pickups over front seats that could move if the vehicle is hit from behind. Affected vehicles all feature manual adjustments for the two front seats, according to a report from Automotive News.
Of the nearly 22,000 vehicles covered under the action, the overwhelming majority - 18,972 -- were sold in the United States. A further 2,575 were sold in Canada, while 103 were shipped south of the border to Mexico. Finally, another 71 were sold outside North America altogether. As of right now, there are no reports of injuries due to the defect.
Naturally, Chevy and GMC dealers will make the repairs free of charge, although it's not clear as of this writing if GM will be notifying owners or just addressing the issue at the truck's first service.

Redesigned 2021 GMC Yukon gets a diesel, AT4 model, Denali-exclusive interior

GMC's most robust family hauler is getting a complete redesign for the 2021 model year, including a new, off-road centric AT4 model, an upscale interior exclusive to its luxurious Denali model, an available air suspension, and, last but not least, a diesel engine.  With Americans obsessing over trucks, it's no surprise that GMC is going hard with its AT4s-for-everybody strategy; the Yukon is no exception. This will be the first model year for the new trim on GMC's largest SUV. This off-road model gets all the goodies you'll need to veer off the beaten path with confidence, including an extra 2.0 inches of ground clearance with the adaptive suspension option (more below), a two-speed transfer case, standard Goodyear all-terrain tires, an off-road mode for GMC's "Traction Select" drive mode system, hill descent control, and some extra underbody skid plates. Since GMC is a premium brand, even the AT4 gets some luxury appointments, such as a heated steering wheel, heated and ventilated front seats, and heated outboard second-row seats. The interior is also adorned in black leather with tan accents and "AT4" embroidery in the seat backs.  Speaking of premium, GMC will introduce an air-ride adaptive suspension with an off-road ground clearance mode as a late-availability option for several Yukon models, and this feature will be included on the Denali trim.  The Yukon and Yukon XL are GMC's variants of Chevrolet's full-sized SUVs, the Tahoe and Suburban. Their fundamental body-on-frame architecture is also shared with GM's half-ton pickup trucks, and thanks to that common engineering, they can also share powertrains. That's normally just a trivial side note when it comes to a new GM SUV announcement, but this time around, it's a bit more meaningful thanks to the introduction of a new light-duty, inline-six diesel in GM's truck lineup last year.  Yep, that means that for 2021, like the Tahoe and Suburban, the Yukon is getting a diesel option. The 3.0-liter Duramax makes the same 277 horsepower and 460 pound-feet of torque as it does in GM's trucks.  GMC's standard engine is still the 5.3-liter V8 that makes 355 hp and 383 lb-ft of torque. The 6.2-liter V8 is also an option like before, producing 420 hp and 460 lb-ft of torque. All engines come with a 10-speed automatic and a choice of rear- and four-wheel drive.

GM follows U.S. trademark for AT4X with application in Mexico

Looks like GM is preparing to return the GMC Sierra 1500 All Terrain X to the marketplace, but with a new name. GM Authority found a trademark application filed in May this year in Mexico for the AT4X moniker. This comes three years after GM filed an application with the U.S. Patent and Trademark Office for the same alphanumeric in February 2016. When GMC introduced the all-new 2019 Sierra, it changed the previous All Terrain trim name to AT4, as seen on the Sierra AT4 we called "offroad overkill." The patent filings lend credence to the idea that the previous All Terrain X trim will soon be introduced by a Sierra 1500 AT4X model.  The erstwhile All Terrain X, introduced for the 2016 model year, took the former All Terrain further into the frame of serious-looking off-roader. On top of the Z71 suspension with a two-inch lift, Rancho monotube shocks, and a locking rear differential, the X added a sport bar for offroad lights, side steps, more dirt-friendly 18-inch wheels in 265/65 mud-terrains instead of 20-inchers on 275/65 all-terrains, a performance exhaust, and a lot more black and body-colored trim. At launch, we said it was "no Raptor threat," and even though GMC launched a 2500HD version in 2017 (pictured), it likely never worried the Ram Power Wagon. We wouldn't expect the equation to change with a possible AT4X, which is a shame, since hardcore OEM offroaders are becoming bro dozers for the mature, moneyed set.
