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.

GM SUV window switch recall urges owners to park vehicles outside

It's not unusual for there to be a lag between an automaker announcing a recall and the official documentation showing up on the National Highway Traffic Safety Administration website. So it's no surprise that a recent GM campaign took about a month to appear in its official capacity. However, there appears to be some big differences between the two reports with potential safety implications.
In late June, GM announced that it needed to recall 181,984 examples of the Chevrolet Trailblazer, Buick Rainier, GMC Envoy, Isuzu Ascender and Saab 9-7x from the 2005-2007 model years, plus the 2006 Chevy Trailblazer EXT and 2006 GMC Envoy XL. The new documents paint a slightly different picture with 184,611 needing repaired and different model years listed.
The reason for the fix is still the same, though. It's possible for fluid to contact the master power window switch module in the driver's door, which can corrode the part. Eventually this could cause a short circuit, leaving the buttons inoperable and potentially leading to a fire. But the new NHTSA documents add an important note: "A fire could occur even while the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been made."

Where the 2023 GMC Sierra AT4X fits into the hierarchy of off-road trucks

The world of off-road pickups sure seems like it's getting crowded, but the reality is that half-ton trucks were always pretty capable, even with what seemed like fairly basic 4x4 packages. It wasn't until recently that manufacturers really started to carve out different off-road niches for their mainstream pickup offerings. With the introduction of the 2022 GMC Sierra 1500 AT4X (alongside its mechanical twin, the Chevy Silverado ZR2), the crowd has grown even thicker. Even we have trouble keeping up with the increased segmentation of off-road pickup trucks, so we threw together this handy guide to help you understand just where these various packages fit into the broader pickup hierarchy. Let's dive in.  Your basics If we say "Z71" or "FX4" to you, both will probably ring a bell. That's because they've been around a few days short of forever and their respective customers have grown so used to these package codes that OEMs got into the habit of just plastering them on the side of so-equipped truck beds. Anybody who sells a pickup truck offers some sort of basic off-road prep package like this one. Z71 is found on GM vehicles; FX4 is Ford's. Ram just calls it "Off Road Group," but no matter what you call them, they're all pretty similar.  Typical upgrades for this category include some additional ground clearance, a basic all-terrain tire, heavy-duty suspension upgrades and likely either a limited-slip or locking rear differential. These are pretty handy for anything beyond a rutted dirt road. On newer trucks — especially on higher trim levels — you'll probably also get some dedicated off-road drive modes.  Mid-range This is where things start to get interesting. To qualify for this category, a locking rear differential is a must. Most of the names in this segment are well-established too, though some (Nissan Titan Pro-4X, anyone?) may not necessarily be on your radar. The Toyota Tundra TRD Pro checks in here, as does the Ram Rebel, Chevy Silverado Trail Boss and GMC Sierra AT4 (no X!).  Realistically, if there's somewhere you need to go and one of these trucks won't do it, you might want to consider a helicopter. But it's 2021, and our thirst for capability is strong, so of course, there's a way to spend more of your money on this type of thing. Onward! Entry-hardcore Here we are, the home of the new 2022 GMC Sierra AT4X and Chevrolet Silverado ZR2. This is a tiny niche, otherwise occupied only by the Ford F-150 Tremor.
