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    

2014 GMC Sierra Regular Cab revealed

Despite initially launching in just the Crew Cab configuration, the lineup of 2014 GMC Sierra and 2014 Chevrolet Silverado trucks will eventually grow to include three cab sizes and three bed lengths. Oddly enough, our first look at the Regular Cab bodystyle has arrived in a General Motors press release discussing the aerodynamics of the new truck, with an image showing a Sierra Regular Cab testing in the wind tunnel. GMC's website says that Regular Cab and Double Cab models will be available by summer.
While it really didn't take too much imagination to figure out what the two-door version would look like, this Regular Cab Z71 looks pretty sharp with its standard-length (6.5-feet) bed - a longer bed will also be offered. In regards to the aero tuning of the 2014 Sierra, these images show just how far GM has gone in maximizing the truck's fuel efficiency and reducing its noise, vibration and harshness (NVH) levels. Interestingly, the press release shows visual evidence that keeping the tailgate up is best for aero - there's always been some Mythbusters-level contention about such things -but GM also says that adding tonneau covers (preferably soft) and running boards can also help improve the overall aerodynamics. Scroll down for all of this aero info in the official press release.

2024 GMC Canyon AT4X AEV teased on 35-inch tires

Last month, Chevrolet Performance teased the 2024 Colorado ZR2 Bison, which will be the ultimate hardcore off-road variant for that model developed in collaboration with American Expeditionary Vehicles (AEV). Since that camouflaged preview appeared, we've welcomed debuts of the competition, the 2024 Ford Ranger Raptor and 2024 Toyota Tacoma TRD Pro. Bookending a solid month of 4x4 delights, GMC teased the coming 2024 Canyon AT4X AEV. We can look at this as the GMC version of the Colorado ZR2 Bison, the Canyon's new-for-2024 AT4X trim given an additional boost in spec and capability. This isn't the truck's first flirt with the public. During media drives for the 2024 Sierra HD AT4X, one of the new heavy duty rigs showed up to the site pulling a trailer bearing a covered pickup. The mid-size form factor, 35-inch tires, and appearance at a GMC event were clues enough to the pickup's identity.  The official preview is proof of what we've been expecting. The revised front fascia wears a high-clearance bumper. Don't expect that winch to be included; the red hook in the tease is a digital add-on. You can expect the winch opening, boron steel underbody skid plating, and Multimatic dampers. The standard AT4X got a three-inch lift over the non-hardcore Canyon variants, in part thanks to being fitted with 33-inch tires. The 35-inch Goodyear Wrangler Territory MT 315/70 17 tires on the AT4X AEV are thought to help provide 11 inches of ground clearance. Beefier wishbones and hydraulic bump stops help protect owners who want to test limits. Reports by folks who walked around the covered truck predict a set of beadlock-capable AEV Salta wheels like the kind sold with the full-size Sierra AT4X AEV Edition. The cover couldn't hide the sport rack in the bed nor the bed-mounted spare tire carrier. Those, like the winch, are likely options that add to the price. Don't be surprised if engine output is unchanged. The 2.7-liter H.O. turbocharged four-cylinder makes 310 horsepower and 430-pound feet of torque. We'll never complain about more, but that's plenty for a truck envisioned as a low-speed obstacle crosser.  All GMC is saying for now is, "An even more off-road capable Canyon is coming." It debuts on July 6. Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
