Next GMC Sierra Denali accidentally leaked on consumer site

Thanks to the quick-to-screen-shot folks at GM Authority, we now have our first look at what is likely the 2014-15 GMC Sierra Denali. GMA reports that the image you see here was temporarily posted on the GMC consumer site, though as you can see now, when you scroll over the "trucks" tab, the image has been removed.
GM Authority states that because the truck in this image wears a blacked-out lower bumper, redesigned grille insert and shiny wheels, this has got to be the upmarket Denali version of the fully redesigned 2014 model year Sierra. The Chevrolet Silverado will be getting a similar treatment, as we've seen in recent spy shots, dubbed the High Country.
Expect the Sierra Denali to ride on large, unique wheels (the one we spied earlier this year was fitted with 21-inch rollers), and feature a huge helping of luxurious interior amenities, as well as premium features like xenon headlamps. An official on-sale date for the Denali has not been released, though it's been reported that the high-grade Sierra, along with its Silverado counterpart, will arrive after the Texas State Fair this summer.

GM alerting truck and sedan owners to a do-over on brake recall

A recall campaign intended to address issues with braking systems on certain 2019 General Motors trucks and sedans may have introduced a new issue, the automaker has acknowledged, and thousands of owners driving repaired vehicles may need to return to their service departments for another update.  The update addresses a fix that was pushed out to owners of more than half a million brand-new GM trucks and sedans that could potentially lose partial braking function, according to the Detroit Free Press. The original software fix helped address situations where the vehicles' anti-lock braking systems would become disabled, which in turn would prevent electronic stability control from activating. Vehicles subject to the recall would often experience software glitches that prevented them from properly communicating the operational state of these systems, meaning drivers would have no idea that their brakes may not behave as expected in an emergency. The 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 were all recalled in the original campaign.  Unfortunately, the early version of this fix appears to have introduced yet another software glitch, indicating that the original fix did not do the trick. Those who have not yet had their cars serviced can rest easy; they will only receive the most up-to-date version of the software fix.  Related video    

Spy photos suggest more rugged GMC Sierra HD AT4X is on the way

Ford has the Super Duty Tremor. Ram has the Power Wagon. GM doesn't yet have a really serious heavy duty pickup off-roader, but these spy shots suggest that may be changing. They show a GMC Sierra HD with plenty of height, chunky tires and a prominent skid plate. We suspect it may be an AT4X trim, to slot above the somewhat trail-oriented AT4 already on sale. Despite the heavy camouflage on each end, we can see right away that this GMC has a new front bumper that's turned up at each end, likely to leave some space for getting tires up to obstacles. There doesn't appear to be the air dam that shows up on all other Sierra HD models, either. Under the front end is a very prominent skid plate. Other interesting aspects include the tires. They appear to be the same model of Goodyear Wranglers used on the Chevy Silverado 1500 ZR2, and not the ones currently in use on the Sierra HD AT4. Also, this extra rugged Sierra features a huge exhaust tip, which seems to confirm the Duramax turbodiesel V8 will be available, probably as an option over the gas V8. This is noteworthy since the Ram Power Wagon is only available with a gas engine. Of course the Ford Super Duty Tremor is available with both gas and diesel engines. The regular Sierra 1500 AT4X was only just revealed last October for the 2022 model year. So we would expect that this heavy duty version would make an appearance for either the 2023 or 2024 model year of the model. It could accompany a light refresh of the truck, again similar to the lighter duty model. We expect it will also feature some additional suspension and drivetrain upgrades to help it compete with the Ford and Ram off-roaders. Related video: This content is hosted by a third party.
