New recall issued in 2019 Chevy Silverado and GMC Sierra brake software saga

General Motors (GM) has issued a new recall for select 2019 Chevy Silverado 1500 and GMC Sierra 1500 pickup trucks that aims to resolve a faulty fix for a previous recall. According to National Highway Traffic Safety Administration (NHTSA) campaign No. 20V055000, a software update for the Electronic Brake Control Module (EBCM) could cause the electronic brake assist to be disabled.  The NHTSA first launched a recall for 463,995 Silverados, Sierras, and Cadillac CT6es on December 12, 2019 due to a software issue in the electronic brake control module (EBCM) that could disable the electronic stability control (ESC) and anti-lock braking system (ABS). As a response and resolution to that recall, GM began to reprogram the software in affected vehicles. GM later learned that the fix was creating a different problem. The installed software had its own error that was disabling the electronic brake assist. If customers see “Service Brake Assist” or “Service ECS" diagnostic warnings, they should park the vehicle and have it towed to a dealership, GM warns. While GM was going through the process of testing, pinpointing the issue, determining action and working with the NHTSA, safety experts have criticized Chevrolet and GMC for not reacting promptly and appropriately.  According to the recall, 148,055 are now affected, all of which do not meet the standards of Federal Motor Vehicle Safety Standard (FMVSS) number 126, "Electronic Stability Control" and 135, "Light Vehicle Brake Systems." To fix the braking issue, GM will once again reprogram the software. GM began notifying owners of the recall on February 10, 2020. Related Video:

2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.

Looking back at the Citation IV concept that likely shaped the GM EV1

Those who forget history are condemned to repeat it. We're not sure how that applies to the GM EV1, but we'd still like to share something from Autoline Daily, an online automotive new show with our friend John McElroy. He's been covering the business for decades now and recently found something interesting: pictures of the 1984 Chevrolet Citation IV concept, seen above. Displayed half a decade before the first electric concept that would become the EV1 (inset), McElroy says it's now clear that the elegant, aerodynamic EV1 took a lot of styling cues from the Citation IV, which was developed in part thanks to GM's new-at-the-time Aerodynamics Laboratory. We agree with him that the spats over the rear wheels, the flush glass, and the covered headlights all bear a certain kind of similarity between the two cars. That the colors almost match is a nice coincidence. The Impact (the concept version of the EV1) looked "frumpier," McElroy says, because it wasn't as long as the Citation. You can read a lot more about the Citation IV here and check out McElroy's thoughts in the video below. Find the Citation starting at around 3:45. This content is hosted by a third party.
