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. A further 112k Corvette models from the 2005-2007 model years are being called in for problems with their low-beam headlamps resulting from a flexing relay control circuit wire that's not meant to bend. GM says it is "aware of several hundred complaints" about this issue, but notes that there have been no reports of related accidents. In addition, over 19k examples of Cadillac CTS from the 2013 and 2014 model years are being recalled over windshield wipers that might not work after a jump start. Finally, GM is also bringing in 477 examples of its 2014 Chevy Silverado, Tahoe and GMC Sierra (though not the Yukon) to fix a problem with a tie rod in its steering rack. As ever, all recall repairs will be performed free of charge, and GM is now estimating that recall-related actions this quarter will result in an estimated $200-million charge against its second-quarter earnings.

General Motors designers sketch the GMC pickups of the future

It's been a busy few years for GMC's team of stylists. They penned a new look for the Yukon and the Yukon XL, and they gave the Sierra 1500 a nip-and-tuck that we'll discover in the coming months. Overhauling these hugely significant models hasn't stopped them from exploring how the firm's design language can evolve. General Motors Design posted two forward-thinking renderings on its official Instagram account that illustrate two ways to move GMC's design identity forward. Karan Moorjani, who works as an exterior designer for the company's autonomous and electric vehicle division, created a truck that breaks all ties with the Sierra. It's characterized by a tall front end with a wide grille and thin LED headlights, sculpted sides, and an unusually low cab. Generously-sized fender flares and tires suggest Moorjani envisioned it as a serious off-roader. Joe Boniface, a member of GMC's Strategic Advanced Design team, took a more realistic approach to moving the design language forward and away from sister company Chevrolet's. His rendering shows a Heavy Duty model with a Denali-branded grille that takes up most of the real estate on the front end and encompasses horizontal rows of LED daytime running lights. It wears less chrome than the current-generation Sierra HD. Nothing suggests either truck is currently on its way to production; General Motors Design regularly publishes sketches from the brand's stylists. Its fascinating Instagram account also shows a Cadillac off-roader, a battle-ready Chevrolet pickup, and a high-riding, open-top two-seater with General Motors emblems that looks like a race car for the Moon.  "Often, these works are not intended for production," a GM spokesperson told Autoblog. "Instead, designers create them to hone their creative skills, to try new shapes or themes, and sometimes simply for the fun of sketching something badass. The GM Design Instagram account was launched to share some of the most compelling, most badass works GM Designers produce." They're sketches created for the sake of sketching, but they give us a peek at the ideas floating around the minds of the men and women who will draw the next generation of General Motors products.

GM Ultium tech can scavenge heat from everywhere, even you

GM likes to give us tidbits about its Ultium platform from time to time, and today it’s telling us about the platformÂ’s ability to capture waste heat from the propulsion system. In addition to capturing from the propulsion system, it can also capture humidity from both inside and outside the vehicle and even from passengersÂ’ body heat. Yes, you, your family and/or your friends are a usable heat source as far as GM EVs are concerned. It then deploys the heat in an advantageous way. If at this point, youÂ’re screaming, "Heat pump!" youÂ’d be right. WeÂ’re talking about an elaborate heat pump system that GM is using for its Ultium-based vehicles. Every Ultium-based GM vehicle gets this system that is covered by 11 patents and four publications. The waste heat it collects is used in a number of ways, but its primary use is to heat the cabin quickly and efficiently. GM claims it can heat the cabin of its Ultium-based vehicles quicker than vehicles with traditional internal combustion engines. Plus, when put to use, GM claims that using the heat pump provides its EVs with up to 10% more range than theyÂ’d have without. Beyond heating the cabin, the heat pump is capable of putting waste heat to use by preheating the battery prior to charging so that you can charge quicker. The system can even cool the propulsion system in preparation for Watts to Freedom (WTF) launch control starts. GM says this was vital in helping the Hummer EV achieve its bonkers 0-60 mph time of about 3 seconds. “Having a ground-up EV architecture gives us the freedom to build in standard features like UltiumÂ’s energy recovery capabilities,” said Doug Parks, GM executive VP of global product development, purchasing and supply chain. “This helps us squeeze more efficiency, performance and overall customer benefit out of our EVs.” GM says itÂ’s been developing heat pump technology since the EV1 and its heat pump. This is the modern evolution of that technology, and GM says itÂ’s going to be implemented in every Ultium-based vehicle as a standard feature.
