2020 Chevy Silverado, GMC Sierra recalled due to faulty brake component

General Motors is recalling 2020 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups to fix a defect in the trucks' brake system. Certain Silverado and Sierra pickups were produced with brake-caliper bolts that were not heat-treated. Without heat-treating, the bolts are weaker than they should be, and there is a risk that they could fail, which would affect the trucks' braking performance, possibly leading to a crash. In total, 20,352 vehicles are affected. Owners of affected trucks will be contacted by GM. Dealers will inspect the bolts and replace those that are defective. Related Video:      

Ford Police Interceptors dominate Michigan State Police testing

Once again, Ford Motor Company builds the fastest police vehicles. The Blue Oval touted the news in an official release following Michigan State Police and Los Angeles County Sheriff's Department testing. Ford did very well. Except for one acceleration metric – zero to 10 miles per hour – the Blue Oval's Taurus and Explorer-based cop cars were the quickest, with particular praise coming for the EcoBoost-powered models, which bested Chevrolet and Dodge's V8-powered variants. Dearborn's products also posted the fastest average times around MSP's vehicle dynamics course. But it wasn't all positive for Ford. The only four-cylinder in the contest, the 2.0-liter, EcoBoost Ford SSP Sedan, had both the lowest top speed, 120 mph, and the slowest acceleration figures. It was also the slowest in track testing. Ford's products also failed to match the braking and top speeds of its rivals from Detroit and Auburn Hills – the rear-drive Charger Pursuit posted the best braking stats of the entire test, while the V8-powered Chevrolet Caprice hit the highest top speed, at 155 mph. Ford did score a top speed award, among SUVs, but at 132 mph, the naturally aspirated Police Interceptor Utility had to share its award with the equally fast, rear-drive Chevrolet Tahoe. The LA County Sheriff's timing isn't publicly available, but according to Ford, the EcoBoost-powered police cars put on a similarly impressive show for cops on the West Coast. We've assembled a spreadsheet on Google Docs that offers an easy to browse comparison of the different stats assembled by the Michigan State Police, and divided the vehicles between standard V6-powered sedans, high-performance sedans (EcoBoost and V8 models), and SUVs.

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.
