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 Chevy Malibu exhaustively tested with four decades of data

Chevy is preparing to unveil its new Malibu sedan at the upcoming New York Auto Show next month. But when it does, it's not like it will have appeared overnight. The development of any new vehicle – especially one as widely produced by a major automaker as the Malibu – involves rigorous and relentlessly punishing tests. In the Malibu's case, that meant 1.5 million miles of driving from the scorching heat of Arizona in July to the frigid cold of northern Canada in January and everything in between. The Bowtie brand also says it incorporated four decades' worth of data taken from vehicles driving in locations around the world since 1972 in order to make the Malibu the best it could be. We'll have to wait to find out the results of all that exhaustive testing, but you can catch a sneak peek at the new sedan in the video above. Four Decades of Data Used to Test 2016 Chevrolet Malibu Recorded customer use drives durability testing for next-generation midsize sedan 2015-03-11 DETROIT – Data collected over decades from across the globe is helping ensure the 2016 Chevrolet Malibu can handle the world's worst roads even if the all-new midsize sedan never drives on them. Data collection boxes are placed in cars in real-world driving conditions around the world. Since 1972, these devices have accurately recorded the harshness and frequency of every jounce, bump and shudder inflicted on the car on roads in the U.S., Russia, Saudi Arabia and developing markets. "Although most Malibu owners will never put their car through similar abuse, we test all new vehicles in extreme climates, inclement weather and on punishing road surfaces," said Dan Devine, Malibu validation engineer. "The 2016 Malibu is definitely up to these challenges." Tests like these ensured the current generation Malibu was dependable and durable, two qualities that in turn helped Malibu stand out from its rivals in important quality surveys, such as J.D. Power's Initial Quality Study and Vehicle Dependability Study. General Motors engineers analyze the data to calculate the precise amount of damage potholes and other hazards create over 150,000 miles. Then the conditions are replicated at GM's Milford Proving Ground in Michigan on three unique road courses, each riddled with simulated potholes of increasing severity. Engineers run preproduction cars through the course up to hundreds of times.

Chevy Colorado, GMC Canyon get updated tachometers due to graphical error

After James Bearing bought a Chevrolet Colorado, he noticed a discrepancy between the truck's spec sheet and the truck's tachometer: Chevrolet said 3.6-liter V6 in the little pickup produces 305 horsepower at 6,800 rpm, but the the tachometer indicates a redline at 6,500 rpm. So either he wasn't making as much power as he was promised, or the tachometer display was incorrect. Bearing said he asked Chevy about it but got no response. Until now. A General Motors spokesman said the rev limiter is indeed set for 6,800 rpm, but the tach graphics "are slightly off" in the Colorado and the GMC Canyon, and submitted an SAE horsepower certification to back him up. If you're wondering how such a thing got past quality control... well, let's just say you're not alone. GM is going to fix "the graphics on future trucks," which makes it sound like Bearing will just have to learn to live with the indicated redline he's got. He could always pretend he's driving a sleeper, with four more ponies waiting to be unlocked in the danger zone for those who dare.
