2019 GMC Sierra Denali MultiPro tailgate and CarbonPro bed explained

When the 2019 Chevy Silverado debuted at the Detroit Auto Show in January, GM's Mark Reuss promised that the new 2019 GMC Sierra would have some significantly different styling and features than its corporate sibling. Previously, the Sierra has been little more than a Silverado with new front and rear fascias and some extra chrome inside and out. Well, Reuss was right. In addition to new sheetmetal, the Sierra exclusively gets the slick MultiPro tailgate and CarbonPro carbon-fiber bed box The tailgate really is trick. At the debut, GMC had multiple demonstrations, with engineers walking us through all six different configurations. Like all Sierra tailgates, the MultiPro version uses an aluminum skin to reduce weight. It's easy to tell which tailgate is which, as the MultiPro has a distinct cutout in the middle where it can fold down or extend. It can be used to extend the bed, drop to allow easier access, provide a sort of workbench, or be used as a step to help get into the bed. Yes, there's even a handle. Ford who? The step itself can support up to 375 pounds, 75 pounds more than Ford's similar tailgate step. This tailgate really is unique to the Sierra and is standard on SLT and Denali models. That said, the power-operated tailgate from the Silverado won't be coming to the GMC. Chevy gets its own exclusive, too. The Sierra's other big exclusive is the carbon-fiber reinforced plastic bed box. CFRP replaces steel inside the bed though not on the fenders. The bed uses four pieces; one for the bottom, one in the back and two along the sides. This isn't a CFRP. There is no steel hiding underneath these panels. Just take a peek underneath. The bed is a composite that uses 1-inch carbon-fiber threads, not a weave. Sheets of CFRP are molded and quenched — a process where the plastic coagulates and solidifies, locking in the carbon fiber — in just 60 seconds. That allows GMC's supplier to crank out these much more quickly. The finish looks like black fiberglass, though an engineer said that this wasn't the final production version. The final model will have different textures in order to improve grip and keep things from sliding around. GMC is touting the material's dent and corrosion resistance, though it remains to be seen how well it holds up to cracking. A video at the reveal showed people going after it with hammers and cinder blocks, but in-person demonstrations weren't available.

Canada opens probe into 250,000 GM pickups, SUVs over brake performance

Transport Canada, the auto safety regulator, has opened a probe into braking issues in nearly 250,000 General Motors full-size pickups and SUVs after U.S. officials launched a similar probe last year, the agency said on its website. The U.S. National Highway Traffic Safety Administration (NHTSA) in November into 2.73 million U.S. 2014-2016 model year SUVs and pickups after receiving 487 reports of hard brake pedal effort accompanied by extended stopping distance that were attributed to deterioration of the engine-driven brake assist vacuum pump. Transport Canada's probe covers 249,700 2015 through 2017 model year vehicles including the Cadillac Escalade, Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon as well as 2014-2017 Chevrolet Silverado LD and GMC Sierra LD vehicles. The U.S. agency said it had reports of nine incidents of vehicles incurring damage as a result of colliding with another vehicle or fixed object at low speeds and reports of two injuries. NHTSA said if the pump fails to operate, the amount of brake power assist can be significantly reduced, extending vehicle stopping distance. The NHTSA sent GM an information request in a Feb. 7 letter. A GM spokesman said he had no update on the investigation. Reporting by David Shepardson; editing by Jonathan Oatis

GM's labor deal with UAW union on verge of ratification

Nov 15 (Reuters) - General Motors' tentative labor deal with the United Auto Workers (UAW) union closed in on ratification as the votes were counted on Wednesday. Following the approval earlier in the day by more than 60% of union members at the Detroit automaker's large Arlington, Texas, assembly plant, additional votes in favor have the deal close to clinching majority approval. The number of union locals, most of which are smaller, still to report vote totals is not large. After several large assembly plants voted against the deal earlier on Wednesday, some media had reported the deal was heading toward failure. But Arlington's support, followed by strong voting in favor by smaller warehouse and parts facilities, has put the deal on the brink of approval. This would mark the first ratification of a deal, which runs through April 2028, with one of the Detroit Three automakers. Ford and Stellantis voting is still under way, and workers at both companies were favoring ratification by comfortable margins. The UAW's GM vote tracking site currently shows approval of the contract leading by a 54% to 46% margin with almost 32,000 workers having cast votes out of about 46,000 UAW-represented GM workers. The Arlington plant, with about 5,000 UAW members, has the most of any GM plant. Voting officially ends on Thursday at 4 p.m. EST, although most votes will be cast on Wednesday. The UAW went on strike for more than six weeks against the Detroit Three, seeking better wages, working conditions and cost-of-living adjustments. All three companies agreed to tentative agreements about two weeks ago. Workers at other GM assembly plants voted against the deal, including 60% of workers at its Fort Wayne, Indiana, truck plant, 53% at its Wentzville, Missouri, plant, 58% of workers at GM's Lansing Grand River plant and 61% of workers at the Lansing Delta Township plant. Seven of GM's 11 assembly plants rejected the deal. In addition to Arlington, workers at plants in Detroit, Fairfax, Kansas; and Lake Orion, Michigan; approved the agreement. Only nine facilities are still listed without vote totals on the UAW vote tracker, including GM's Lockport, New York, components plant with about 1,200 members. Those voting in favor of the agreement have a lead of almost 2,500 and many of the facilities still to come include workers who stand to receive large pay increases upon ratification.
