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:

Hotter Cadillac ATS-V+ could use LS7 power

Rumor has it Cadillac is working on an even hotter version of the ATS-V, possibly called ATS-V+. And the latest intel from Motor Trend suggests this new model might have a great, big V8 under the hood. The V8 in question is the high-revving, naturally aspirated 7.0-liter LS7 from the Camaro Z/28. The hand-built engine makes 505 horsepower and 481 pound-feet of torque in the Z/28 – a nice increase over the 464 hp and 445 lb-ft in the standard ATS-V, which uses a twin-turbocharged 3.6-liter V6. Motor Trend says the ATS-V+ will come to market with an eight-speed automatic transmission, as well as the seven-speed manual 'box from the Corvette. A dual-clutch transmission will come to market later. Of course, we'll believe it when we see it. But an LS7-powered ATS-V sure sounds like a great package to us. Here's hoping.

2014 Cadillac CTS images leak from somewhere

The redesigned 2014 Cadillac CTS will be unveiled this Tuesday on the eve of the New York Auto Show, but as often happens, some images of the car have leaked onto the web a few days early. Previously, the only information we had on the 2014 CTS concerned the all-new twin-turbo V6 engine that will be found underhood, rated at 420 horsepower and 430 pound-feet of torque.
While none show the new car in its entirety, the images do show much of the front end, particularly the headlights that feature vertical bars of LEDs that start down low as foglights and continue up to the top of the front fenders. They're similar to the lighting design first shown on the XTS and ATS, except the lower portions are much taller.
There are also views of the rear end and one of the taillights, as well as an interior shot of the front passenger door. The latter image has us most intrigued, as it shows some very high end materials being used in the new CTS interior. The low-gloss wood trim, in particular, looks very premium.
