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 re-recalls 11k SUVs

General Motors is recalling a bunch of previously recalled SUVs because, well, they still aren't quite fixed. The latest repairs are necessary on 10,974 SUVs in North America, including 9,932 in only the US. Affected models include the 2006-2007 Buick Rainier, Chevrolet Trailblazer, and GMC Envoy; plus the 2006 Trailblazer EXT and Envoy XL. While not listed by NHTSA, a statement by GM to Autoblog says the 2006-2007 Saab 9-7X and Isuzu Ascender are also affected. In these SUVs, it's possible that liquid could get into the driver's door master power window switch module and cause a short circuit. This could potentially lead to a fire, and owners are urged to park the vehicles outside until repaired. GM has been trying to fix this issue for years. It started as an investigation into fires, and that led to a recall for about 250,000 vehicles in cold-weather states. A nationwide campaign came in 2013 for 193,000 of them in the US. Last year, the automaker decided to replace the whole module as a repair. However in a recent investigation of these recalls, GM discovered that this latest group of SUVs never received the new part. According to documents submitted to NHTSA (as a PDF), "Some dealers incorrectly used the labor code associated with module replacement when, instead of replacing the module, they only added a protective coating to the module." To fix things this time, the models finally get the correct component.

Certain 2006 Chevrolet TrailBlazer EXT and GMC Envoy XL, and 2006-2007 TrailBlazer, Envoy, Buick Rainier, Saab 9-7X and Isuzu Ascender vehicles may continue to have a condition in which the printed circuit board inside the driver's door may corrode and short if exposed to certain fluids such as melted snow containing road salt. GM is aware of four fires but no crashes, injuries or fatalities associated with the expanded recall. The total number of vehicles being recalled, including Canada, Mexico and exports is 10.974. Customers are urged to park these vehicles outside until repairs have been made. GM reported this recall to the NHTSA on September 23.

Some 2012-13 Chevy Volts may not have enough battery coolant

The 2012 and 2013 model year Chevrolet Volt extended-range plug-in vehicle may have a battery glitch caused by low coolant levels. No recall has been issued and General Motors is taking care of the issue at no cost to drivers. Some of the affected Volts may have lower-than-advisable coolant levels because of some pesky air pockets in the car's cooling circuit. When the coolant levels get too low, the charging system for the battery powering the car's onboard generator (i.e. the Rechargeable Energy Storage System, or the RESS) may be shut down, turning one's Volt into a run-of-the-mill gas-powered car, and a pricey one at that. The Car Connection says GM is advising owners of the '12 and '13 Volts to contact their local Chevy dealer for a free fix. GM representatives didn't immediately respond to a request for comment from AutoblogGreen for more details. We believe this is a separate issue than the one that brought 8,000 Volts back to the dealers for a battery coolant fix, what GM called a "voluntary customer satisfaction effort," a few years ago. General Motors sold 23,094 Chevy Volts last year after selling 23,461 Volts in 2012, so that fix-it list may get fairly lengthy. Check out a GM-Volt.com user thread related to this issue here. *UPDATE: Chevrolet spokesman Randy Fox confirmed in an e-mail to AutoblogGreen that the company issued a service bulletin to dealers that they may need to top off coolant levels on certain Volts because of the issue, and that the vehicle will "return to normal charging operation" once that's done.
