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.

GMC Hummer EV pickup reveal postponed

We’re pretty excited about the all-electric Hummer pickup coming from the GMC brand. GM is too, enough to spend Super Bowl money on an ad teasing it. Today, we received an update from GM about the Hummer EV, with good news and bad news. The bad news: GM has announced that it is postponing the May 20 reveal for the Hummer. With the coronavirus throwing the proverbial wrench into a number of vehicle operations, including reveals, we canÂ’t say weÂ’re surprised at all. The good news, GM assures us, is that development continues “undeterred.” GM understandably hasnÂ’t provided a new debut date for the GMC Hummer EV, but it did provide us with the new short teaser video above. WeÂ’ve seen other details in previous teasers, as well. We were lucky enough to see the Hummer EV in person last month just before the pandemic began causing the world to grind to a halt. At GMÂ’s EV Day at its Warren, Mich., campus, the Hummer pickupÂ’s exterior was on full display. ItÂ’s a big, off-road-ready pickup complete with giant all-terrain rubber and tow hooks. It features removable roof panels for access to the open sky, which appears to be depicted in the teaser above. It features sail panels behind the C-pillars, similar to those on the Chevy Avalanche and Honda Ridgeline. Its bed was concealed with a tonneau cover, but it sported GMCÂ’s MultiPro tailgate that we first saw on the Sierra Denali. Interior photos showed a spacious interior with blocky shapes, squared hourglass vents that mirror the look of the taillights and a lunar theme that incorporates the topography of the Sea of Tranquility into things like the floor mats and speaker covers. It also has a large infotainment screen as well as a digital instrument panel. The Hummer pickup will be offered with a number of electric powertrain options, the most powerful of which will provide 1,000 horsepower and a 0-60 mph time of less than three seconds. Like the rest of the next generation of GM EVs, it will use the automakerÂ’s new Ultium modular battery and powertrain technology. While we donÂ’t have further details about a potential reveal date, we also know a Hummer electric SUV based on the pickup will follow at some point. It, too was on display at GMÂ’s EV Day. It looks exactly like the Hummer pickup from the rear doors forward, but with a shorter wheelbase and enclosed cargo area in the rear. It also sported a liftgate-mounted spare.

2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.
