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:

Automakers' sound systems: Crank it, don't yank it

Years ago, one of the first things most music lovers did after buying a new vehicle was drive to an aftermarket stereo shop to get the crappy stock components swapped for better gear. And you'd typically get not only better sound but also more bang (and boom) for your buck. But in the past decade or so, the overall quality of OEM audio has dramatically increased, while car electronics became more complex, removing the incentive for most new vehicle owners — and all but the most hardcore DIYer — to start from scratch. In 2010, I did a comparison of the average costs for OEM electronics vs. similar offerings from the aftermarket, and back then automakers' stock premium systems were by far the best bargain — and are probably an even better value now. The premium 14-speaker, 1,200-watt JBL system in the all-new 2019 Toyota Avalon is a prime example of this trend. It's standard on the top two Limited and Touring trims and is available as a $680 audio upgrade on the XLE and XSE. I doubt you can even buy 14 speakers and 1,200 watts of amplification from the aftermarket for 700 bucks, much less have it all installed. And because the system is bundled with Toyota's Entune infotainment system, Apple CarPlay and a surround-view camera, removing the head unit means you would likely lose these features. Another advantage of OEMs and their audio partners is they can design the car around the audio system. In the past, automakers would typically place speakers where convenient for packaging, not for optimal sound reproduction, and audio engineers were forced to compromise. But as with the Avalon's premium JBL audio system, this is starting to change. At a recent behind-the-scenes peek for media into the process of developing the system, Toyota and Harman engineers delved into the minutia of sealing the inner panel of the front doors to create an enclosure for 6x8-inch woofers, making space in the pillars for JBL horn tweeters and extensively measuring the acoustic properties of the interior to tune the sound to the space. I'm met some creative and skilled car stereo installers, but none with a degree in psychoacoustics. The system is also the first to feature Quantum Logic Surround that creates a multi-channel listening experience from two-channel sources. And it includes Harman's Clari-Fi processing that "rebuilds key details lost" in compressed audio formats used by streaming music services and MP3s.

Buick Velite 6 to come in PHEV, electric versions for China

In addition to the all-electric Enspire crossover concept revealed this week ahead of the Beijing Auto Show, Buick is adding a new production variant to its Velite series of electrified vehicles for China. It's called the Velite 6, a plug-in hybrid that will launch this year in Buick's largest market. A full-electric version, shown in the lead photo above at right, is coming later. Buick already sells a vehicle called a Velite 5 in China, which is essentially a rebadged Chevrolet Volt, only with a higher electric-only driving range. This one is based on the Velite concept PHEV introduced in late 2016 at Auto Guangzhou. The PHEV and battery-electric versions look nearly identical, with a wide stance, plenty of creases and a hatchback design that bears some similarities to the longer 2018 Regal TourX wagon. The Velite 6 uses two AC permanent-magnet synchronous motors, a lithium-ion battery and a 1.5-liter four-cylinder combustion engine. Buick says combined gas-electric driving range is 435 miles, which is 15 miles greater than the Volt. Buick will assemble what it calls the "new-generation" ternary battery pack at its new SAIC-GM Power Battery Development Center in Shanghai. The company says the Velite 6 electric vehicle "will adopt a new-generation pure electric drive system to offer customers a smooth, quiet and natural driving experience." Both models get the cloud-based Buick eConnect technology, which allows over-the-air software updates, real-time integration with China's WeChat social media network, and other digital perks. Owners will also be able to use their smartphone as the vehicle's key, and they can also authorize others to use the car through their phones. China has long been Buick's largest market, with more than 1.18 million vehicles sold in 2017 compared to just 219,231 in the U.S., and the country has established aggressive mandates for production of electric vehicles. GM has plans to add 20 new electric and fuel-cell vehicles globally by 2023. Related Video:
