GM recalls 740,000 vehicles over daytime running light issue

General Motors is recalling over 740,000 vehicles due to a daytime running light issue that causes all of the affected cars to run afoul of Federal Motor Vehicle Safety Standards. Vehicles affected by this recall are spread across many of GM’s brands. Models include the 2020-2023 Cadillac CT4 and CT5, 2021-2023 Buick Envision, 2022-2023 Cadillac Escalade and Escalade ESV, 2022-2023 Chevrolet Silverado 1500, Suburban, Tahoe and 2022-2023 GMC Sierra 1500, Yukon, and Yukon XL. GM says that the daytime running lights may remain on in these cars when the headlights are activated. This is a problem, because FMVSS rules require that the daytime running lights deactivate once the headlights turn on. If the DRLs remain on, GM says that could result in additional glare, thereby increasing the risk of an accident. The cause of this failure to deactivate the DRLs comes from body control module software that “under a combination of certain pre-conditions, could fail to deactivate the DRLs,” according to GM. Other GM vehicles were tested, but due to a difference in software or hardware, they remain unaffected. If this is reminding you of another recent GM recall, youÂ’d be right, as GM recalled another 340,000 vehicles for the same issue last month. After that original issue was found within GM, the company began looking into its other cars to determine if the population was larger than originally thought. GM found the additional vehicles included in todayÂ’s recall have the problem. The fix will either be via an over-the-air update or it will require you to bring the vehicle into a dealer for a software update, depending on which vehicle you have. Owner notification letters letting folks know what is necessary are currently scheduled to go out on January 23, 2023. Related video: Cadillac Escalade Infotainment Review

2016 Chevy Volt will not need premium gas

Buried in the new technical details of the 2016 Chevy Volt released yesterday was a throwaway line about a small but important change that's due to the new 1.5-liter, four-cylinder engine. The first-gen Volt has always required premium gas but the new powerplant will be happy burning plain old regular. The Volt's chief engineer, Andrew Farah, told AutoblogGreen that the change was due to today's Volt owners explaining they were not happy paying for top-shelf petroleum. "The ability to use regular unleaded was based directly on customer feedback," he said. "Since the range extender is an all-new engine, it was optimized to use regular unleaded at the outset. Using regular fuel will not have effect on vehicle acceleration or other performance factors." As Larry Nitz, GM's executive director of vehicle electrification, told AutoblogGreen yesterday, the new engine is more powerful and quieter than the outgoing 1.4-liter engine that's used in the current Volt. Fuel economy and EV range specs for the next-gen Volt are not expected until the full car is revealed at the Detroit Auto Show in January.

2018 Chevy Sonic caught testing in The Motor City

Despite its role as the entry point into Chevrolet's lineup of sedans in America, the Sonic can be a fun little urban runabout in the same vein as the Ford Fiesta and Honda Fit. It's also impressively fuel efficient. Suffice it to say, then, that the Sonic is way better than the Aveo it replaces. And, as you can see from these spy shots, the next version of the Sonic is currently being tested in the wintry climes of Detroit, Michigan. The 2018 Chevy Sonic will be based on an updated Gamma platform that will be shared with the all-electric Chevy Bolt. In place of that's car electric motor and massive battery pack will be either a naturally aspirated four-cylinder or small turbocharged engine. Our spy shooters suggest a three-cylinder engine is also a possibility. While it's clear from these spy photos that the development of the next Sonic is well underway, nobody is quite sure where it will be built. Last October, we reported that 500 workers at GM's production facility in Orion Township were being laid off due in part to slow sales of the Sonic – you can thank the growing popularity of crossovers for that – and that plant is now being retooled for production of the Bolt. It's entirely possible that GM has decided to move production of the Chevy Sonic to Mexico, which would allow it to build a more profitable vehicle at Orion Township alongside the Bolt.
