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 looks to combat high theft rates on SUVs with added tech

The Cadillac Escalade has been at or near the top of most-stolen and insurance-loss lists for more than seven years, until it dropped to number six earlier this year. In 2011 it was fitted with a host of new security features to address its easy-to-override features and that has brought the number of thefts down, but when eight of the ten most stolen rides are large SUVs from General Motors, no one will argue that something else needs to be done.
Thus, GM has fitted this same theft-deterring tech to the 2015 Suburban, Tahoe and Yukon. The Suburban and Tahoe will get the steering lock that the Escalade and Yukon already get, plus bolted-down third-row seats to deter thefts like this, stronger door lock cylinders and shields, and side-cut keys to inhibit picking.
Additional security measures in a Theft Protection Package can be purchased for $395, consisting of sensors on the greenhouse glass and interior, an incline/tilt sensor and added "key control systems" to make it more difficult for the men in black balaclavas to steal what you bought.

370,000 new Silverado and Sierra pickups recalled over fire risk

General Motors announced late Friday that it will recall around 370,000 Chevrolet Silverado and GMC Sierra fullsize pickups from the 2014 model year over a possible fire risk. The recall covers select 4.3-liter V6 and 5.3-liter V8 models, which can evidently suffer engine compartment fires due to the overheating of exhaust components. GM notes that the fire issue may be preceded by a check engine light and an "engine power reduced" message on the driver information display.
Thus far, GM is aware of eight fires stemming from this problem (although only three of those incidents affected customer-owned vehicles), and all of the fires were reported in areas with "very cold weather." GM is urging owners to not leave their vehicles unintended while idling. No injuries have resulted from the fires in question.
The Detroit-based automaker has pledged to start mailing out recall letters on January 16. The fix, which involves software reprogramming, is estimated to be a 20-minute repair, and will be made free of charge.
