GM tells NHTSA pickup truck electronic glitch is 'inconsequential'

General Motors has been enduring some serious problems with recalls recently, and it is hoping to avoid launching another major safety campaign. 200,921 2014 Chevrolet Silverado and GMC Sierra pickups are under the microscope due to a rare problem with their instruments, an issue GM calls calls "inconsequential to motor vehicle safety." The Detroit-based automaker believes that the glitch is so minor that it has filed a petition with the National Highway Traffic Safety Administration asking the government safety watchdog for permission to pass on recalling the vehicles.
The fault at issue can occasionally cause the instrument cluster to reset when drivers use the steering wheel controls to browse songs from an external media device connected to the truck's USB ports. If a song's title information exceeds 2,000 bytes, according to The Detroit News, then the instrument panel can reset, which in turn causes the gauges, shift position indicator and cruise control telltale to turn off briefly. When rebooting, other instrument panel lights may briefly illuminate without their functions actually being activated. GM claims that if this does happen, the instrument display lights go out for about 1.5 seconds and the bulb check lasts a further five seconds. However, this snafu has no actual affect on the truck's operation. The glitch is present in trucks built between January 29, 2013, and October 28, 2013.

GM's fullsize SUVs boost highway mileage by nearly 10 percent

We met the redesigned 2015 versions of the Chevrolet Suburban and Tahoe, and the GMC Yukon and Yukon XL at the 2013 LA Auto Show. Improved gas mileage numbers have been announced to go along with the improved exteriors and interiors, with city mileage improving by seven percent and highway mileage going up by nearly ten percent; you'll now get 16 miles per gallon in the city and 23 on the highway.
The only applies to models with the 5.3-liter engine, though, not the premium Yukon Denali and Yukon XL Denali SUVs with the 6.2-liter motor. Still, the 5.3 gets you more power than previously, with 355 horsepower and 383 pound-feet of torque underfoot, on top of the improved fuel economy numbers. The 6.2-liter sticks with official mpg ratings of 15 highway, 21 city. There's a brief press release below with words straight from the horse's mouth.

Chevy Silverado edges Ram 1500 in Consumer Reports two-truck shootout

Forget Corvette versus Viper. When it comes to important head-to-head comparisons, fullsize trucks are where domestic automakers really care. And until the redesigned Ford F-150 makes its debut, the Chevrolet Silverado is going to have plenty to brag about thanks to a new Consumer Reports shootout against the Ram 1500.
It was a tight race among these V8-powered titans, but the all-new 2014 Silverado (and its GMC Sierra twin) barely edged out Ram's updated pickup with a score of 81 points - enough to make it the institute's top-rated fullsize truck on the market. Its narrow victory over the Ram, which finished just three points back, was due to its superior fuel economy, better towing and payload capacity and conveniences like a lower step-in height, easy-to-use tailgate and rear bumper steps that make loading and unloading less of a chore.
Importantly, CR notes that buyers with less heavy-duty truck needs might actually prefer the Ram over the Chevrolet, since its high points include a smoother ride thanks to its coil spring rear suspension, dominant infotainment system with Uconnect, and a big thumbs up for the available Hemi engine and eight-speed automatic transmission.
