2019 GMC Sierra carbon fiber bed: How it's made

FORT WAYNE, Ind. — The redesigned 2019 GMC Sierra has some pretty nifty features, and the one that has had the most attention is the MultiPro flipping and folding tailgate. But the Sierra also features the first-of-its-kind carbon fiber truck bed. It's interesting, of course, for its capabilities, such as being 62 pounds lighter than the all-steel box. It even adds more cargo volume since the material can be assembled and shaped differently from steel. As it turns out, the assembly process is cool, too, which we learned when GMC invited us to see the beds being made. Every GMC carbon fiber bed starts out as perfectly flat sheets of thermoplastic carbon fiber. The sheets consist of a mix of fibers and resins, a bit like the molded carbon fiber parts Lamborghini uses. The sheets are manufactured by Japanese company Teijin, which collaborated with GMC to develop the bed. They're all delivered to Continental Structural Plastics (CSP) in Fort Wayne, Ind., for construction into the actual bed. The company, a subsidiary of Teijin, makes a wide variety of composite and plastic parts for the car industry, including body panels for the C7 Chevy Corvette. The rectangular sheets are cut to shape and stacked up at a giant stamping press. Robots pick up sheets and slide them onto a conveyor that goes into a large oven. The heat softens the parts so they can be stamped. The large primary bed parts such as the base are stamped by CSP's enormous 3,600-ton press, and the smaller ones go through a 1,000-ton press. Each press can do different parts using different stamping dies, and CSP switches between dies to produce different batches of parts. After stamping, the parts roll out mostly ready for assembly, but there are rough edges that are trimmed off by water-jet cutters. These cutting machines also create holes for fasteners and for parts such as tie-down hooks and lights. The stamping process also provides the carbon fiber bed with a unique Easter egg. On the bottom of the base of the bed, there are two words: "Connors Way." This is a tribute to Tim Connors, who was the chief engineer of manufacturing at GM and a strong proponent of the carbon fiber bed. He was tragically killed in a motorcycle crash a few years ago. The words were added to honor him, and they were fortunately approved for production. There are some components to the bed that aren't stamped from the flat sheets of material.

GM seatbelt recall affects over 1m Silverados and Sierras

The Basics: General Motors will recall 895,232 examples of the 2014-2015 Chevrolet Silverado and GMC Sierra 1500 pickups in the US. The campaign will also affect the trucks in markets worldwide, and the total number the company will recall is 1,037,982. The Problem: A steel cable connects the seatbelt to the vehicle, but over time repeated bending can cause the part to fatigue and separate. Injuries/Deaths: None reported. The Fix: Dealers will enlarge the side shield opening and install a pusher bracket on the tensioner. Technicians will also replace the entire tensioner assembly if necessary. If You Own One: GM will contact owners about the recall. The company hasn't said when those notifications would begin. More Information: There are still about 3,000 new examples of these older pickups at dealerships. Until mechanics fix the problem, these vehicles are subject to a stop-sale. Similar problems have affected the General's vehicles in the past. In 2015, the company recalled over 400,000 units of the 2011-2012 Chevrolet Malibu for fatiguing cables. It also hit over a million Lambda platform crossovers in 2014. GM Recalling Certain 2014-15 Pickups to Repair Seat Belts DETROIT – GM is voluntarily recalling 895,232 model year 2014-15 Chevrolet Silverado and GMC Sierra 1500 pickups in the United States because the flexible steel cable that connects the seat belt to the vehicle can fatigue and separate over time as a result of the driver repeatedly bending the cable when entering the seat. This issue was discovered through warranty data, and there have been no reports of crashes, injuries or fatalities related to this issue. For trucks in the field, dealers will enlarge the side shield opening, install a pusher bracket on the tensioner, and if necessary, replace the tensioner assembly. The recall in the United States includes a stop-sale of approximately 3,000 new 2014 and 2015 model year pickups still on dealer lots. Dealers will repair the vehicles prior to delivering them to customers. Customers will be notified by General Motors. They also can look up their vehicle identification number (VIN) at either https://vinrcl.safercar.gov/vin/ website or at https://my.gm.com/web/portal/ownercenter to see if their vehicle is part of the recall. GM also will voluntarily recall and repair these models in other countries where they are sold, including Canada, Mexico, and several countries in Latin America and the Middle East.

GM natural gas-powered vans recalled due to possible leak

General Motors is recalling almost 3,200 of its compressed-natural-gas powered utility vans because of possible leaks. GM and the National Highway Traffic Safety Administration (NHTSA) released a notice last week saying that 3,196 Chevrolet Express and GMC Savana CNG vans are on recall, though no accidents have been reported due to the possible issue. The recall is specifically for vans for model years ranging from 2011 to 2014. The recall stems from a potential leak from the compressed natural gas high-pressure regulator, and such a leak could cause a fire or explosion. GM will replace the vehicles' high-pressure regulator in order to fix the problem, will do it free of charge and is instructing owners to contact Chevrolet or GMC customer service to arrange for the parts replacement. Utility vehicle makers like General Motors have pushed for fleet sales of CNG-powered vans and trucks for the past few years and have touted them for their cheaper refueling costs relative to standard gasoline, not to mention the fact that natural gas can be readily sourced from throughout North America (thanks, fracking). According to CNGPrices.com, compressed natural gas sells for about $2.22 a gallon, on average, while the AAA is pegging the average price of gas at $3.34 a gallon. NHTSA has posted information on the recall here. Featured Gallery News Source: NHTSA via Reuters Green Chevrolet GM GMC Natural Gas Vehicles CNG gmc savana
