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:

2018 Buick Enclave slims down for spy shots

Most vehicles are refreshed every five years or so. New technology and styling is required to keep up with the latest trends. Although this cycle is common, there are some vehicles, like the Buick Enclave, that seem to stick around far past their expiration date. We now have spy shots of what appears to be the nine-year old Enclave's replacement. Although the vehicle in the photos is completely covered in camouflage, we can make out the new Buick family grill. There are a set of LED running lights up front and what appear to be a location for foglights toward the bottom. The camo covering is cut in places to allow gaps for sensors, presumably for parking and other driver aids. Out back, the rectangular taillights don't appear to be production ready. The whole rear, especially the glass, looks smaller than the outgoing model, though it is difficult to properly tell through the camouflage. The rear bumper has wide cuts for the dual exhaust pipes, and again the camo has cutouts for sensors. The side profile reveals the biggest change with the new Enclave. The current version shares a platform with the Chevrolet Traverse and the original GMC Acadia, some of the largest vehicles on the market. The all-new 2017 Acadia scaled down in order to compete against midsize crossovers and now has more in common with the smaller, Chinese-built Buick Envision. That doesn't mean the Enclave and Acadia are entirely separate. Both the Enclave and upcoming Traverse will ride on a stretched version of the Acadia platform. The general profile remains the same, but it's apparent that the vehicle in these photos is longer than the new GMC. Most other details are speculation. The Enclave will most likely arrive with GM's 3.6 liter V6. With the introduction of the Envision, the Enclave is expected to move upmarket to compete against the Acura MDX and Volvo XC90. Because of the slightly narrower shape, passenger seating is expected to fall to seven. The new crossover will probably lose a bit of weight with the redesign. The new Buick is expected to debut next year as a 2018 model. Look for the reveal of the Chevrolet Traverse replacement as well.

Buick reveals new Verano in Shanghai

The lion's share of the new vehicles being showcased at the Shanghai Motor Show this week may never make their way to US showrooms. But Americans will surely want to note the unveiling of the all-new Buick Verano. The current compact sedan in the Buick lineup arrived in 2011, and is now preparing to enter its second generation with the model you see here. Details are the only element more scarce than photos (GM has released one thus far), but we can see that the new Verano adopts more dynamic styling than the model it replaces. The design borrows elements from the Riviera and Avenir concepts, with a more steeply raked windshield and rear glass said to give the new Verano a more elongated look (and lower drag coefficient) than its compact footprint would dictate. Up front you'll see Buick's signature waterfall grille, flanked by HID xenon headlights with LED daytime running lights and taillamps. Motivation comes courtesy of a 1.5-liter turbocharged Ecotec four, driving 166 horsepower and 184 pound-feet of torque through a new seven-speed dual-clutch transmission. The 17-inch wheels are shod with Continental rubber. Just how many of these specifications will remain relevant when the new Verano reaches Buick dealers on this side of the Pacific remains to be seen, but for now you can delve into the full press release below.

The brand's latest entry in the mid-range passenger car segment has a stylish exterior, class-leading fuel efficiency and precise handling. The Verano is targeted at individuals who value a personal and dynamic driving experience. Design inspired by Buick Riviera and Avenir concept cars The Verano was inspired by the new Buick Riviera concept car, which premiered in 2013, and captures the design essence of the Buick Avenir concept car, which debuted at this year's North American International Auto Show in Detroit. It represents an innovative interpretation of Buick's classic styling while exemplifying the elegance and dynamism of Buick's new-generation products.
