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:

2016 Camaro gets most revealing tease yet

Chevrolet started its long teaser campaign for the 2016 Camaro by just revealing the exhaust manifold and front frame, but as time has passed the company has slowly unveiled more. In the latest glimpse ahead of the pony car's May 16 debut, we're actually getting to see the model's profile completely undisguised. As suggested by the recent tease of the rear and hood, the 2016 Camaro wears a sharper, more angular design than the current model. This is especially the case when you look at the taut lines making up the rear. Chevy claims that the new shape underwent 350 hours of wind tunnel tests to be able to generate left lift, improve cooling and reduce wind noise in the cabin. A smooth underbody pan is among the aerodynamic tweaks, and it runs from underneath the front grille to the center of the Camaro. Chevy asserts that all of the changes at the front help reduce lift by 30 percent. Related VIdeo: 2016 Camaro is all about the Aero Total aerodynamic lift improved by 30 percent for improved stability 2015-05-11 DETROIT – After 350 hours of wind tunnel testing – often 24 hours a day – the new Camaro will slip more easily through the wind, and drivers of the Camaro SS will experience a marked improvement in reduced aerodynamic lift. These changes illustrate the lengths the aerodynamics team went to for improved performance, stability, cooling and lower wind noise intrusion "The importance of aerodynamics increases exponentially as we increase vehicle performance," said Kirk Bennion, Exterior Design manager. "As engine output increases, we need more engine cooling. As acceleration and top speeds climb, we need to reduce lift for better high-speed stability. However, we cannot make any changes at the expense of increasing drag, which can hurt fuel economy. "To balance these different aerodynamic targets, we tested literally hundreds of changes on the new Camaro, millimeters at a time." For example, the initial design called for the lower grille bars to be set at a 20-degree angle to the horizon. However, after meticulous testing, the team improved engine-cooling airflow by 1 percent by shifting the angle to 13 degrees – a change that achieved the airflow target while maintaining the original grille design. And rather than a traditional front air dam to reduce aerodynamic lift, the team developed a flush belly pan that stretches from the front grille to the center of the vehicle.

The Chevrolet Bolt is headed to China as a Buick SUV

When spy photos of what appeared to be Chevrolet Bolt EV with some minor front- and rear-end updates circulated last week, Autoblog surmised that GM was working on some sort of Bolt-based vehicle — potentially a crossover — to be sold in China as a Buick. We may just have corroboration for that theory. On Thursday, Motor1.com spotted a story published earlier this week on the Chinese site Auto Home which claims that GM has applied to sell an all-electric SUV under the Velite 7 nameplate in China.  There's little differentiating the Velite 7's exterior from the Bolt EV's, apart from bumpers, badges, and a little extra ground clearance. Up front, the bowtie is replaced by a round Buick badge, and the bumper picks up an almost Prius-like appearance thanks to contrasting vertical elements and a thin grille bleeding into the head lights to give it a full-width appearance. Chevy Bolt-based prototype View 16 Photos If the Chinese report is accurate, there is one significant difference under the skin. Per the application, the Buick crossover variant is to be powered by a 174-horsepower electric powertrain. That's down 26 horsepower from the Bolt EV's powertrain, and we can't help but think that a lifted Buick variant might just need every pony it can get.  The needs of the Chinese market are unique, and we're certain GM knows what it's doing if these figures are accurate. We have no reason to believe Buick plans to sell the Velite 7 EV here in the States, though we expect an updated Chevy Bolt eventually, and we wouldn't be surprised if Buick brings something along shortly to fill the void left by the departure of the Regal sedan and its variants.  Related Video:
