GM files for Z71 Trail Boss trademark

Try as they might to keep their plans a secret, automakers have their hands tipped through a variety of methods – be they through loose lips, spy shots or patent and trademark applications. That's how we know, in this instance, that General Motors is working on (or at least considering) an off-road machine wearing the name Z71 Trail Boss – the name which our compatriots at AutoGuide.com tell us that GM has registered for use on light-duty trucks. Now if that alphanumeric designator sounds familiar, it should. GM has long used it to designate the off-road packages on many of its body-on-frame trucks from Chevy and GMC. These days you can order a Z71 package on the Chevy Colorado, Silverado, Tahoe and Suburban and on the GMC Canyon, Sierra and Yukon. The package typically includes components like a beefed-up suspension bits, high-capacity air cleaner and underbody protection plates. The Trail Boss designator would seem to suggest something further reaching than a suspension package, though. Just what it would entail we don't know; minds immediately start running toward Chevy or GMC going after the Ford F-150 Raptor, but we'll likely be looking at something closer to the Trailhawk packages Jeep offers on the likes of the Renegade and Cherokee.

GM recalling 54k Cadillac SRX, HD pickup models

There are more recalls to report General Motors, but these latest actions pertain to newer examples of the Cadillac SRX, Chevrolet Silverado HD and GMC Sierra HD. With so much scrutiny on the company's recall strategy, GM is under increasing pressure to call in defective models more quickly, and it appears to be doing so here.
Here in the US, the automaker is recalling 50,571 Cadillac SRX crossovers from the 2013 model year fitted with the 3.6-liter V6 because the transmission control module programming can cause a three- or four-second lag in acceleration at low speeds. The explanation filed with the National Highway Traffic Safety Administration states, "if the following sequence occurs within two seconds: during an upshift from first to second gear (8-10 mph), the driver then brakes the vehicle to less than 5 mph, and then accelerates again," the delay can occur. According to Automotive News, the recall effects 56,400 vehicles worldwide, and the company is not aware of any crashes caused by the problem. The fix consists of a transmission control module (TCM) reflash.
In a separate recall, GM is repairing 51 Chevrolet Silverado HD and GMC Sierra HD pickups from the 2015 model year in the US. In vehicles with diesel engines and dual fuel tanks, the nuts that connect the fuel pipe to each side of the transfer pump between the tanks may be improperly torqued, which could cause a fuel leak. Obviously, this could be a fire hazard. The remedy is simply tightening the hardware. According to GM spokesperson Alan Adler, there have been no fires actually caused by the potential leak. "Only 21 of the trucks are in customer possession and they can be fixed anytime because there are no parts involved. The others are being fixed at dealerships," Adler said in an email to Autoblog.

GMC Canyon next generation previewed with off-road AT4X trim

GMC is preparing to give the Canyon, its smallest and most affordable pickup, a complete makeover. While we won't see the truck for a few months, the company released a preview image to give us an idea of what to expect and confirmed the lineup will include an AT4X model. Although the teaser keeps most of the sheetmetal hidden, the truck appears to receive a more chiseled hood and concave door skins that should make it look less slab-sided. The fenders are eye-catching as well: They're more punched-out that the current-generation model's. Keep in mind that we're looking at the AT4X trim, which will be positioned as the off-road champion of the range and should consequently get a brawnier-looking design. Other off-road goodies include big Goodyear Wrangler tires wrapped around 17-inch beadlock-capable wheels, plastic wheel arch flares, and rock rails. GMC is keeping additional details under wraps, but we're guessing suspension tweaks are part of the package as well. After all, the current-generation AT4 benefits from a one-inch suspension lift and skid plates, among other upgrades. This isn't the first time we've seen or heard of the Canyon AT4X. Our spy photographers caught a camouflaged prototype that looks taller and considerably more rugged than the AT4 in July 2021, and the Canyon AT4 OVRLANDX concept introduced in August 2021 seemingly previewed some of the features that will trickle down to the production model, including the rock rails and wheel arches. GMC will unveil the next-generation Canyon this summer, and we expect to hear more about it in the coming weeks. And, if a new Canyon is around the corner, that likely means that the next Chevrolet Colorado isn't far behind. Both will compete directly against the new Ford Ranger, which has only been unveiled for overseas markets as of writing and which will spawn a range-topping, V6-powered Raptor. Another competitor the duo will need to fend off is the Nissan Frontier, which got its first update since the 2005 model year for 2022. Already offered on the 2022 Sierra, the outdoorsy AT4X trim will spread across the GMC range in the coming years. Nothing is official yet, but earlier spy shots strongly suggest that the Sierra Heavy Duty will be treated to the AT4X treatment in the not-too-distant future.
