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:

GMC caught using Rivian R1T image for Sierra Denali EV Photoshop

The rise of electric start-ups have many legacy automakers checking their rear view mirrors as they scramble to join the EV party. Most wouldn't like to admit it publicly, but we know that at least some folks at General Motors are keeping an eye on Rivian. That's because a recent post on social media account by the General Motors design department appears to have used an image of the Rivian R1T, but heavily photoshopped. The post was intended as a peek of the GMC Sierra Denali EV's rear view. Eagle-eyed observers like AllCarNews soon noticed many familiar elements to the rendering, including the wheels and tires, mirrors and doors. Even the backgrounds are identical, including some leaves that the truck is kicking up. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Seen side by side, the two pickups' similarities don't end there. The Sierra EV is wider, but the cab's rear pillars and glass look the same as the Rivian's, just stretched horizontally. The rear bumper and its license plate cutout and reflectors on either side look a bit too close for comfort as well.  The post as since been deleted. A GM spokesperson explained the situation to The Drive, "The GM Design Instagram channel is meant to give followers an inside look at the process of designing new products and the creative teams behind it. Often, these posts use sketches made for internal studio use during design development. The sketch in question was intended for internal use only, and was posted without the necessary approval. It has been removed from the GM Design Instagram page." Automakers often use products from the competition as benchmarks or design inspiration. Designers sometimes use existing images as a starting point as well, in order to quickly get an idea down "on paper". They just tend to do it in private. A juggernaut like GM using an image from an upstart like Rivian is embarrassing for the General, but surely an ego boost for the EV brand.  When dealing with an up-and-comer, perhaps it's best to take a page from Mad Men's Don Draper. In season four of the advertising drama, a newspaper calls the hot shot exec for a quote, after a young rival publicly says he's gunning for Draper. Draper knows exactly who the reporter is talking about but when asked for comment says, "Never heard of him." Related Video This content is hosted by a third party.

GM shows off 'digital vehicle platform' enabling more in-car tech and OTA updates

It appears to have dropped the sobriquet "Global B," but General Motors' new electrical architecture has bowed in drawings and video. This is the "digital vehicle platform" GM president Mark Reuss spoke to Reuters about in 2015, saying it would move a great deal of a vehicle's computer work to the cloud and enable over-the-air updates. Reuss took the microphone for the debut, too, saying, "Our new digital vehicle platform and its eventual successors will underpin all our future innovations across a wide range of technological advancements, including EVs and expanded automated driving." The system will go into production later this year, appearing in dealerships first either on the 2020 Cadillac CT5 or the mid-engined 2020 Chevrolet Corvette. Yes, these are the same electronics cited for delaying the launch of the C8 Corvette over excessive draw, security and getting the more-than-100 computer modules to communicate seamlessly. When Car and Driver asked about that, GM replied with "No comment." Volkswagen's having the same issues with the Mk8 Golf right now, though, so GM isn't alone, and this will be the new normal among OEMs for a while. What's certifiable is that the new architecture is robust enough to handle 4.5 terabytes of data per hour, which is five times what GM's current wiring can handle. And thanks to Ethernet connections of 100 Mbps, 1 Gbs and 10 Gbs, communication within and without the vehicle happens much faster. The advances mean better screen resolutions, better battery management for hybrids and electric vehicles, the capability for over-the-air updates and "functionality upgrades throughout the lifespan of the vehicle." Cadillac's Super Cruise has already been lined up as a leading candidate for constant improvements in the driving assistance suite, a key part of GM's "vision for a world with zero crashes, zero emissions and zero congestion." And whenever GM decides to take the plunge, it will mean a 48-volt electrical system. More than 300 specialists worked on the digital platform, and security was a huge part of the task. We've already heard that GM consulted with Boeing and military contractors on how to prevent hacking. The carmaker has an internal Product Cybersecurity group that reached out to the research community, and created a "bug bounty" program to crowdsource uncovering any flaws.
