GM recalling another 2.7 million vehicles in five separate campaigns

The recalls keep rolling in from General Motors, evidently keen to avoid repeating the mistakes of the ignition-switch debacle and clean house. This time they're all coming at once, with five separate recalls announced together covering approximately 2.7 million vehicles.
The largest of the five actions involves over 2.4 million units of the previous-generation Chevrolet Malibu and Malibu Maxx, Pontiac G6 and Saturn Aura in order to fix brake light wiring harness, which have been found to be susceptible to corrosion. The recall is separate from the 56k Aura sedans which GM recently recalled over faulty shift cables, not to mention the previous massive recall of 1.3 million vehicles - some of them the same models - but appears to have resulted from the National Highway Traffic Safety Administration investigation that started with the G6 almost a year ago.
The second-largest campaign involves the 2014 Chevy Malibu, specifically those fitted with GM's 2.5-liter engine and stop/start system, approximately 140,000 examples of which has been found to have problematic brakes. The issue does not appear to be connected to the recall of 8k Malibu and Buick LaCrosse sedans (also involving brake woes) which we reported upon last week. Four crashes have been reported in such models, but GM admits it's not yet clear if the problem was a contributing factor in the accidents.

Watch the live reveal of the 2014 Chevy Silverado and GMC Sierra [UPDATE]

UPDATE: The trucks have been revealed. Click here for all of the official details.
As promised, Chevrolet and GMC are offering a live webcast of the world premiere for the all-new 2014 Silverado 1500 and Sierra 1500. After being teased with spy shots and blurry images like the one above for ages, now is the time to see the trucks in the metal, for real (well, as 'real' as it gets on a webcast, at any rate).
Shift your eyes down just below to see the reveal as it happens, starting at 9:30 AM EST. We anticipate having loads of images full technical information to share after the webcast, too, so truck aficionados should stay tuned. We'll also be bringing you live images of both trucks too, when we see them on the show floor at next month's Detroit Auto Show.

2014 GMC Sierra Regular Cab revealed

Despite initially launching in just the Crew Cab configuration, the lineup of 2014 GMC Sierra and 2014 Chevrolet Silverado trucks will eventually grow to include three cab sizes and three bed lengths. Oddly enough, our first look at the Regular Cab bodystyle has arrived in a General Motors press release discussing the aerodynamics of the new truck, with an image showing a Sierra Regular Cab testing in the wind tunnel. GMC's website says that Regular Cab and Double Cab models will be available by summer.
While it really didn't take too much imagination to figure out what the two-door version would look like, this Regular Cab Z71 looks pretty sharp with its standard-length (6.5-feet) bed - a longer bed will also be offered. In regards to the aero tuning of the 2014 Sierra, these images show just how far GM has gone in maximizing the truck's fuel efficiency and reducing its noise, vibration and harshness (NVH) levels. Interestingly, the press release shows visual evidence that keeping the tailgate up is best for aero - there's always been some Mythbusters-level contention about such things -but GM also says that adding tonneau covers (preferably soft) and running boards can also help improve the overall aerodynamics. Scroll down for all of this aero info in the official press release.
