GM announces 3 new recalls affecting 1.7M vehicles in North America [w/video]

Still embroiled in the ongoing ignition switch recall, General Motors announced today three more discrete recalls, affecting a grand total of 1,546,900 vehicles in the US. The Detroit News reports that some 1.7 million vehicles are affected overall in North America. The first and largest of the trio of new recalls concerns some 1.18-million Buick Enclave and GMC Acadia crossovers from the 2008-2013 model years, Chevrolet Traverse from 2009-2013 (pictured above) and Saturn Outlook vehicles from 2008-2010. All of the crossover utilities may have an issue with the wiring harness for their seat-mounted side airbags. Apparently, the vehicles are equipped with a Service Air Bag warning light that, if ignored, "will eventually result in the non-deployment of the side impact restraints." Those restraints include the side airbags, a front-center airbag if the vehicle is so equipped and seatbelt pretensioners. Dealers of affected vehicles will be instructed to remove driver and passenger side airbag wiring harness connectors, and then "splice and solder the wires together." The second recall affects 303,000 Chevrolet Express (pictured right) and GMC Savana vans from model years 2009-2014, and with gross vehicle weights under 10,000 pounds. Said vehicles do not comply with a head impact requirement for unrestrained occupants, and will need a reworking of the instrument panel material to be sent back on the road. It doesn't sound as though there's a quick fix for this one, as the GM press release states: "Unsold vehicles have been placed on a stop delivery until development of the solution has been completed and parts are available." Finally, the third recall affects 63,900 Cadillac XTS luxury sedans from model years 2013 and 2014. A brake booster pump may be susceptible to corrosion by way of the relay, potentially causing and electrical short, overheating, melting of plastic components and even engine fires. GM says it is aware of two engine fires in unsold XTS models and two cases of melted parts. Repairs for the issues affecting the XTS have not not mentioned by GM in the release. The Detroit News is also reporting that along with news of the triple-recall, GM is taking a $300-million credit to help pay for the repair costs, and to deal with the ongoing costs associated with the ignition switch recall. In an attempt to explain just what GM has been doing in the face of these very serious issues, newly minted CEO Mary Barra has addressed the issues in a new video.

Both Android Auto and Apple CarPlay slated for Chevrolet lineup

Long awaited, the race among automakers to keep drivers connected to their smartphones has officially entered a new era. Hyundai said Tuesday it would be the first manufacturer to put Google's Android Auto into a production car, the 2015 Hyundai Sonata sedan. Not to be outdone, General Motors said today it'd offer both Android Auto and Apple's CarPlay on several Chevrolet models set to hit dealerships this summer. By giving car buyers the choice between these rival phone-projection systems, Chevrolet hopes to quell concerns from prospective customers worried about the compatibility of their smartphones and vehicles. "It's about providing choice," said Alicia Boler-Davis, GM's senior vice president for global connected car consumer experience. "No two customers are alike, and we cannot expect a single solution that works for every driver in every situation." Across the industry, automakers are rushing to add both to their cars as a growing base of customers seek an array of connected features. Estimates from automotive technology research firm SBD indicate smartphone-integrated content is available in 36 percent of current vehicles, and the company expects that penetration rate will grow to 84 percent by 2025. For Chevrolet, the systems will be available on select 2016 iterations of the Cruze, Camaro, Volt, Spark and Malibu as early as next month, and appear on 14 Chevy models overall for the 2016 model year. They're available on all trim levels, but they only work with the company's MyLink infotainment package installed in the cars, and the first to hit showrooms will only work on the seven-inch touchscreen models. "CarPlay and Android Auto, these are things that are addressable to the broad market, and I think it makes a lot of sense for GM to put it into Chevys first," IHS Automotive senior analyst Mark Boyadjis said. Via physical connections, both Apple CarPlay and Android Auto allow users access to smartphone features like turn-by-turn directions, phone calls, voice-to-text messages and music streaming. Interfaces are similar to the ones found on the respective smartphones, but on the dashboard, they're redesigned for a simpler, in-car experience. Fonts are larger, for example, and easier to press on a touchscreen. CarPlay relies heavily on Siri so that drivers spend more time staring at the road instead of their touchscreen. That sounds good, at least in theory.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
