GM alerting truck and sedan owners to a do-over on brake recall

A recall campaign intended to address issues with braking systems on certain 2019 General Motors trucks and sedans may have introduced a new issue, the automaker has acknowledged, and thousands of owners driving repaired vehicles may need to return to their service departments for another update.  The update addresses a fix that was pushed out to owners of more than half a million brand-new GM trucks and sedans that could potentially lose partial braking function, according to the Detroit Free Press. The original software fix helped address situations where the vehicles' anti-lock braking systems would become disabled, which in turn would prevent electronic stability control from activating. Vehicles subject to the recall would often experience software glitches that prevented them from properly communicating the operational state of these systems, meaning drivers would have no idea that their brakes may not behave as expected in an emergency. The 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 were all recalled in the original campaign.  Unfortunately, the early version of this fix appears to have introduced yet another software glitch, indicating that the original fix did not do the trick. Those who have not yet had their cars serviced can rest easy; they will only receive the most up-to-date version of the software fix.  Related video    

Chevrolet will preview electrified Silverado-like truck at CES 2021

After abandoning its fight against California's lawmakers, General Motors is shifting its electrification offensive into high gear. CEO Mary Barra will give the opening keynote address at the 2021 Consumer Electronics Show (CES), which will be held online, and Chevrolet will provide a peek at its electrified pickup during the event. Insiders familiar with the carmaker's plans told Bloomberg that Barra's address will highlight ways that electrification can improve the environment and society in general. General Motors president Mark Reuss will speak, too, and his remarks will be followed by a video that will highlight several future products, including what the sources referred to as "a plug-in Chevrolet pickup, some Cadillac models, and vehicles for other brands." These comments ask more questions than they answer, because plug-in means many things in this context. Chevrolet's electric Bolt is a plug-in vehicle, as is the upcoming GMC Hummer, but the plug-in hybrid Jeep Wrangler 4xe is one, too, and it's clearly not all-electric. It's often been assumed that Chevrolet's upcoming electrified truck will be electric, but it might arrive with a hybrid powertrain or a gasoline-powered range extender. Chevrolet could also follow Ford's lead and plant a stake in both the hybrid and the electric pickup segments. It's too early to tell if Chevrolet will unveil the same truck it previewed during a presentation earlier in 2020. Shown briefly, it wore a highly futuristic design that gave it a sleeker look than the current-generation Silverado. Cadillac's presentation promises to be interesting, because the company hinted it might abandon gasoline entirely by 2025, several years earlier than expected, even though its dealers aren't all on board with the shift. Going electric-only in about four years would force the brand to conduct a massive overhaul of its range. As of writing, there is not a single electric Cadillac in showrooms, but the Lyriq will arrive in late 2022 as a 2023 model. It's difficult to tell what's in store for other brands, but there are several cars that General Motors could show during CES. Buick doesn't sell an electric car in the United States yet, for example. Alternatively, GMC is working on an SUV variant of the Hummer, and it has started developing an electric truck. Going back to Chevrolet, our crystal ball tells us we'll see more of the 2022 Bolt EUV during the next edition of the tech show, too.

Recharge Wrap-up: BYD electric buses at Special Olympics, hybrids perform better than rated

A new study finds that real-world fuel economy of hybrids could be significantly higher than EPA ratings. Researchers at the University of Vermont, with the help of their own "total on-board tailpipe emissions measurement system," found the fuel savings of Toyota Camry Hybrid over a standard Camry to exceed its sticker values by 18 percent on the highway and 33 percent in the city. The results of this study suggest that the projections of the fuel and emissions benefits of hybrids could be adjusted to reflect more these more positive real world values. The study's authors, Britt A. Holmen and Karen M. Sentoff, say more research is warranted based on these findings, and that "similar studies can be used to develop robust models of all types of HEV platforms under actual driving conditions and improve quantitative estimates of the future fleet contributions to the US CO2 emissions inventory and petroleum consumption."

BYD electric buses provided transportation at the Special Olympics 2015 World Games in Long Beach, CA. Shuttling 6,500 athletes required the help of multiple charter companies, including local buses from the Chinese automaker. "BYD stepped up majorly as one of our key supporters and their tremendous efforts made our athletes feel welcomed," says Long Beach Community Foundation President and CEO, and 2015 Host Town Transportation Coordinator Marcelle Epley. "We depended on them, and they came through 100 percent." Both Los Angeles and Long Beach have recently decided to purchase electric buses from BYD. Read more in the press release below.
