GM under fire from safety advocates over braking problem caused by recall fix

Safety experts are lambasting General Motors over what they say is the automaker’s slow notification of owners of certain 2019 sedans and trucks that a recall fix could cause power braking to fail and increase the risk of a crash, the Detroit Free Press reports.  GMÂ’s original recall in December targeted about 550,000 Cadillac CT6 sedans and Chevrolet Silverado 1500 and GMC Sierra 1500 pickups, all from the 2019 model year, over potentially defective electronic stability control and antilock brakes. In that case, GM said the errors would not show up as a diagnostic warning on the instrument cluster. But after GM had done recall work on 162,000 vehicles, about 1,700 owner have complained that their power brakes didnÂ’t work after they had the recall done and then used the OnStar app to start their vehicle. GM then issued a supplemental fix for customers whoÂ’d already had their vehicles serviced. In this case, a diagnostic warning should illuminate saying either “Service Brake Assist” or “Service ECS,” which GM says is a signal that a customer should not drive the vehicle and instead call their dealer, which will tow the vehicle and have it repaired. Safety advocates say the automaker hasnÂ’t gone far enough to protect customers. “The fact that you could potentially start a vehicle and not have brakes is a pretty risky proposition,” Sean Kane, president of the Safety Research and Strategies, which works on auto issues for plaintiffs and governmental organizations, told the Freep. “The fact that they wouldnÂ’t notify owners (sooner) is pretty stunning.” GM told the Freep it was required to notify the National Highway Traffic Safety Administration and file paperwork before it notified customers about the original recall, which was made Dec. 12. It then had to investigate and resolve the problem created by its original recall fix before alerting customers. GMÂ’s call center and dealers are contacting the remaining 900 customers who havenÂ’t yet had the update made to the original recall repair. GM also hired a vendor to send recall letters to the 550,000 customers affected by the original recall notifying them about the update. There are no known injuries or deaths related to the problem.

2021 GMC Yukon Denali First Drive | Finally living up to the Denali reputation

For most of its existence, the GMC Yukon has been a virtually identical twin to the Chevy Tahoe. It would have some exterior differences, maybe a couple of different features, but aside from the badging, you’d be hard-pressed to distinguish the two. That also applied to the supposedly more luxurious Denali trim level. This new generation of Yukon mostly continues the trend, but now the Denali stands out more. It gets a unique interior designed to bridge the gap between the Yukon and Cadillac Escalade, and includes high-end features such as the Yukon's otherwise optional 6.2-liter V8 and magnetic suspension with air springs. All of this combined lets the 2021 GMC Yukon Denali live up to its luxurious reputation. It's easily the version to get if your bank account allows. It really is the interior that makes the biggest difference. The entire dashboard and door panels are exclusive to not only the Yukon, but the Denali trim level specifically. The dash design is more squared-off and truck-like, but itÂ’s offset by the use of some excellent materials. Large portions of the dash are wrapped in leather with stitching. ThereÂ’s also a large panel of matte-finish open-pore wood, available in multiple colors, on the passenger side. Some metal trim and nicely textured knobs adorn the center stack. The doors get this wood and leather, too. The center console features some attractive, stylized stitching as an extra adornment. The result is a place that feels high-quality and luxurious, but not in a garish or flashy way. Sort of a utilitarian luxury, which fits the look and character of the Yukon Denali. There are aspects of the interior that are shared with other Yukons and Tahoes, though. You get the same slightly odd but perfectly usable push-button shifter, the 10-inch touchscreen infotainment system, 15-inch head-up display, dual 12.6-inch backseat screens, and the same amount of interior space. These are all good things. The infotainment system is responsive and easy to use, while also offering the same advanced trailering camera system that so impressed in the Chevy Silverado HD. The head-up display is also large and legible, and fortunately not cluttered with too much distracting information. The best part, however, is the amount of space.

GMC and AEV reveal Sierra Grande upfit SEMA concept

If there was any question as to whether GMC was dedicating resources to its off-road models, it was dismissed the instant American Expedition Vehicles entered the conversation. The two have already partnered to produce a GMC-branded alternative to the Chevrolet Colorado ZR2 Bison. The 2024 GMC Canyon AT4X AEV Edition is midsize pickup perfection, but the collaboration is far from over. With GMC now pushing the AT4X package on its heavy-duty pickups, AEV is looking for ways to explore the space.  "The Sierra Grande Concept represents AEV’s creative vision of how the company would further elevate the adventure-ready foundation of the GMC Sierra HD AT4X into a legendary overlanding rig," AEV said in its announcement The Sierra Grande is all Sierra HD AT4X underneath. The steering knuckles, control arms, rear suspension and butter-smooth DSSV dampers are all lifted directly from the production truck. This SEMA-bound concept is the quintessential upfit smorgasbord, boasting everything from add-on lighting to upgraded underbody protection. There are even two winches — one for the front and one for the back. If you ask us, they should have gone ahead and put one on each side too.  The snorkel pairs nicely with the 40-inch BF Goodrich tires, and the onboard air system guarantees you're never in a pickle when you hit pavement to head home. The bed is aluminum, but the skid plates are stamped steel (as is the brush guard). The front winch is rated for 12,500 pounds; the rear for "just" 9,500.  Unlike the Canyon AT4X AEV Edition, the Sierra Grande is merely an exercise — for now, anyway. We suspect that GMC has plenty more in store for its off-road trucks.  Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
