GM recalls 3.6 million vehicles for airbag-software problems

The Basics: General Motors is recalling 3.64 million vehicles across its lineup for an airbag-related issue. The recall covers the 2014-2015 Buick LaCrosse, Chevrolet SS, and Spark EV; 2014-2017 Chevrolet Corvette, Trax, Caprice PPV, Silverado 1500, Buick Encore, and GMC Sierra 1500; and 2015-2017 Chevrolet Tahoe, Suburban, Silverado HD, GMC Yukon, Yukon XL, Sierra HD, Cadillac Escalade, and Escalade ESV. The Problem: Affected vehicles have a sensing and diagnostic module that controls the airbags and seat-belt pretensioners. The software it uses has a defect that can prompt the module to run a diagnostic test under specific driving conditions, which will also deactivate the front airbags and pretensioners. This means that it would be possible for those safety systems to not activate in a crash, potentially leading to injury or death. Injuries/Deaths: General Motors began an investigation that led to the recall after a 2014 Silverado was involved in a crash in which the airbags did not deploy. No information was given as to injuries or deaths. The Fix: Owners can bring their vehicles to a local General Motors dealer where a software update will be installed to fix the issue. The fix will be free of charge. If you own one: General Motors will contact owners of affected cars, and owners can check whether their vehicles are affected by visiting entering their vehicle identification numbers at either the GM Owner Center website or the NHTSA website. Owners can then schedule a time to have the update installed. Related Video:

2016 Cadillac CT6 to get an aluminum body?

Well this is interesting: A hot-off-the-press report in Automobile claims the coming Cadillac CT6 will have an aluminum body. Most write-ups on the CT6 claim it will have a body that's a combination of aluminum and high-strength steel - Automobile itself wrote of "high-strength steel, aluminum, and steel stampings" in October. An all-aluminum body would be quite the reversal, contradicting the last four months of reportage and company statements on the matter. Mark Reuss, EVP of global development at General Motors, told The Detroit News in October, "We will create with the CT6, the world's most advanced body structure... [and] it's not aluminum. It's a stronger, smarter, safer premium luxury vehicle." It echoed the earlier Automobile story in saying the CT6 would use GM's "patented welding technology with high-strength steel, aluminum and steel stampings and castings." That same month, the Wall Street Journal ran a piece titled, "GM Won't Follow Aluminum Strategy in Future Cars," in which Reuss said, "making big statements around all carbon fiber, all aluminum, all magnesium, they're very interesting," and that GM wouldn't be doing it. That piece also circled back to a material mix and GM's special welding process, saying the CT6 "will have a body made of aluminum, high-strength steel and other materials, and will be 100 kilograms (220 pounds) lighter than a similar-sized car made of high-strength steel." We don't know what kind of body Cadillac's new assault on luxury is going to wear, but now we can't wait to find out.

2016 Cadillac CTS-V prepares to kick ass, take names

Some stories write themselves. This post on the North American International Auto Show debut of the 2016 Cadillac CTS-V is one of them. This 200-mile-per-hour sedan pilfers the 6.2-liter supercharged V8 from the Chevy Corvette Z06, and puts it to the same tire-devastating effect, offering up 640 horsepower and 630 pound-feet of torque. An eight-speed automatic – please join us in a moment of silence for the dearly departed manual CTS-V – then dispatches the force-induced thrust to a very large, sticky set of Michelin Pilot Super Sport tires. To ensure the CTS-V can tear your face off with lateral Gs as well as accelerative Gs, Cadillac stiffened the car's structure by 25 percent, fitted magnetic ride control and fitted the aforementioned tires. Beyond the mechanicals, a substantial rear spoiler, front splitter and diffuser improve grip through aerodynamics. Keeping drivers pinned during all this tire shredding and face tearing is the task of meaty, two-piece Recaro sport seats, which are found in a luxuriously appointed cabin, complete with 4G LTE connectivity, a Bose stereo and Siri Eyes Free. There's even a Performance Data Recorder, which will be on hand to record your miscues if (or perhaps when) the car's extreme abilities outpace your own talents. Take a look at our array of live images from the CTS-V's official debut at the 2015 Detroit Auto Show.
