Next-gen Chevy Silverado and GMC Sierra may use carbon fiber

It's been generally accepted that the next generation of full-size GM trucks will use some sort of strong, lightweight material for the beds while retaining steel for the cab. While aluminum seems like the most obvious choice, according to Automotive News, the Chevy Silverado and GMC Sierra will incorporate both aluminum and carbon fiber in their beds. The publication cites sources from within GM, though it seems the introduction of this comparatively exotic material mix is still a few years off. While carbon fiber is both stronger and lighter than steel and aluminum, it takes significantly more time and money to produce, essentially relegating the material to small-volume cars. The main benefit for trucks is the resulting reduction in weight to improve fuel economy without sacrificing the tough, rugged capabilities truck buyers expect. The Ford F-150 made the switch to aluminum for the 2015 model year and it's proved highly successful. It seemed like it was only a matter of time before the competition followed suit. Automotive News says that the next-gen trucks will launch with aluminum beds and that it will take a couple of years before we'll see any carbon fiber incorporated into the design. Even then, only look for the composite material on higher-trim models, with a trickle down to lower-spec trucks possible further in the future. In 2011, GM announced it was working with Japan-based Teijin Limited on a carbon fiber reinforced thermoplastic. There's a good chance that material's introduction will be on trucks.

GM recalls 200k Hummer H3s for fire risk

An issue with fires erupting in some Hummers has prompted General Motors and the National Highway Traffic Safety Administration to issue a recall for nearly 200,000 vehicles around the world. The bulk of them are in the United States. According to the first statement (below) obtained by Autoblog from GM, the issue stems from the HVAC system in Hummer H3 models. The connector module for the blower motor has, in certain cases, overheated, melted the surrounding plastic, and started a fire. 42 such cases have been reported, including three instances of occupants citing minor burns. GM confirms that two of those three cases lead to the vehicle being destroyed in the fire, but states that no crashes or fatalities have resulted. The issue affects 196,379 examples of the 2006-10 H3 wagon and the 2009-10 H3T pickup, with 164,993 estimated to be in the United States. In order to fix the issue, dealers are being instructed to replace the relevant parts of the connector and harness. In a second, unrelated campaign, GM is also calling in 50,731 Chevy Spark and Sonic small cars – 45,785 of them in the US – due to a software glitch. In those affected vehicles fitted with the base radio and OnStar system, the audio system may not be able to switch out of turn-by-turn direction mode, causing the display to go blank and all sound to mute – including key safety warnings. In addition, the system may not switch off, draining the battery. GM states that no crashes, injuries, or fatalities have resulted from this issue, and all that dealers will need to do in this case is reflash the software.

The heat could melt the plastic surrounding the connector module, increasing the risk of a fire. Dealers will replace the affected portion of the connector and harness. GM is aware of three reported minor burns and 42 fires but no crashes or fatalities related to this condition. Including Canada, Mexico and exports, the total recall population is 196,379. ### General Motors is recalling 45,785 2014-2015 model year Chevrolet Sparks, and 2015 model year Chevrolet Sonics in the U.S.
