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.

Engine block heater issues force GM to recall 324,226 diesel heavy duty trucks

General Motors has issued a recall on 324,226 diesel heavy duty trucks that could be susceptible to short circuits, and consequently, potential fire. The recall affects several models of heavy duty Chevrolet Silverados and GMC Sierras with optional engine block heaters. GM is recalling seven different truck models spread across three years. The recall affects the 2017-2019 Chevrolet Silverado 2500HD, 2017-2019 Silverado 3500HD, 2019 Silverado 4500HD, 2019 Silverado 5500HD, and 2019 Silverado 6500HD, plus the 2017-2019 GMC Sierra 2500HD and 2017-2019 Sierra 3500HD. Specifically, it includes these models with the 6.6-liter Duramax diesel engines and the optional engine block heater. The recall technically deals not with the engine block heater itself, but the way it is connected. According to NHTSA campaign No. 19V328000, the engine block heater cord or the terminals that link the cord to the heater could short circuit. A short circuit could potentially damage engine components and result in a fire. According to The Detroit News, 19 fires have been reported but nobody has been injured. GM has yet to figure out a fix, and thus has not yet released a notification schedule for affected customers. If you believe your vehicle is part of the recall, contact GM customer service at 1-586-596-1733 and use reference number N182206310.

Porsche and Buick earn top honors in J.D. Power Sales Satisfaction Index Study

Customer satisfaction with car buying has been at a low point over the past few years, as price increases, inventory shortages, and COVID restrictions have complicated every part of the process. There are signs of improvement, however, as J.D. Power’s 2023 U.S. Sales Satisfaction Index Study showed that customer satisfaction has improved slightly from a year ago. J.D. Power rates satisfaction on a 1,000-point scale, finding that it improved seven points to 793 from last year. Improving inventory levels and a slow leveling off of prices have contributed to that improvement, and fewer people are paying above MSRP for new cars. Some auto brands performed better than others with sales satisfaction. Porsche ranked highest among premium brands, followed by Alfa Romeo. Buick took the top spot among mass-market brands, with GMC, Chevrolet, and Mitsubishi behind. J.D. Power also handed out segment-level awards: Premium Cars: Porsche Premium SUV: Porsche Mass-Market Car: Chevrolet Mass-Market SUV/Minivan: GMC Mass-Market Truck: GMC Despite the increase in sales satisfaction, thereÂ’s still room for improvement to reach pre-pandemic levels. J.D. Power noted gaps in salesperson knowledge as an area of improvement. Buyers rated salespeople much better during a gas vehicle purchase than with EVs, citing their expertise as a challenge. Pricing remains a challenge despite an improvement since 2022, and satisfaction is still below pre-pandemic levels. Mass-market buyers reported a slight bump in satisfaction, while premium buyers felt that pricing was less fair than a year before. ItÂ’s an interesting contrast, showing that dealer pricing tactics can significantly impact satisfaction with the sales process. Fewer people may be paying more than MSRP, but several premium models still list with significant markups. Even more interesting is PorscheÂ’s top spot on the satisfaction list, as its cars often sell with huge upcharges, and itÂ’s exceedingly tricky even to get a build allocation for some models.
