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

Honda, Chevy reveal low-drag speedway aero for Indy 500

As the two automakers currently participating in the IndyCar Series, both Chevy and Honda were invited this year not only to provide engines to the teams on the starting grid, but to develop their own aerodynamics packages as well. Both revealed their designs for the road-course races a few months ago, but with the Indy 500 approaching at break-neck speed, they've now unleashed their aero approaches for speedways. Both are based on the Dallara DW12 chassis introduced to the series a couple of years ago, but sacrifice some of their downforce at the altar of speed. And you can tell as much from looking at them: both Honda (above) and Chevy (below) have streamlined their designs, with single-plane front wings, lower-profile rear wings and fewer winglets on the body and around the wheels in between. The idea is to allow the cars to reach higher top speeds with less drag, while offering the necessary amount of downforce for the banked turns. With the four opening road-course rounds complete, teams using either automaker's equipment will keep the existing aero kits on their cars for the Grand Prix of Indianapolis on the infield course next week, then switch to the speedway package for the Indianapolis 500 later this month. Then it'll be back and forth for the rest of the season as the circus switches between road courses and speedways. Honda Unveils 2015 IndyCar Super Speedway Aero Kit Apr 30, 2015 - SPEEDWAY, Indiana - To be used at the Indianapolis 500 - Manufacturer seeking 11th Indianapolis 500 victory since 2004 - First public running to take place Sunday at Indianapolis Honda today debuted the "Super Speedway" aero kit of aerodynamic upgrades and components its teams will use at this year's 99th running of the Indianapolis 500. The Honda Super Speedway Aero Kit, produced by Honda Performance Development, Honda's racing arm in North America, includes a variety of individual aerodynamic components fitted to the existing Honda-powered Dallara Indy car chassis. All are intended to give Honda's six Indy car teams – encompassing a potential 17 '500' entrants - the ability to maximize performance at the 2.5-mile Indianapolis Motor Speedway oval and other large ovals ( over one mile in length) on the 2015 Verizon IndyCar Series schedule. "We're excited to unveil our Super Speedway aero kit, the newest element in this era of enhanced manufacturer competition in the Verizon IndyCar Series," said Art St. Cyr, president of HPD.

Thanks for keeping us on our toes, Detroit Auto Show [w/poll]

Here at Autoblog, we love unexpected debuts at auto shows – and judging by our Detroit Auto Show comments and traffic, you do, too. Surprise reveals have been fewer and farther between in recent years with so many ways for vehicles to be teased or leak out, but this week's show has been a revelation. More to the point, it's been a series of revelations, with automakers from around the globe successfully delivering a brace of concept and production surprises. It's made our jobs a lot more exciting and challenging this week, and even though it's actually more work to react and run-and-gun when the sheet is pulled on a surprise reveal than it is to publish an already-written embargoed story, we've had more fun covering this show for you than any domestic show in memory. We hope you've enjoyed the surprises along with us. To that end, borrowing the words of an unnamed automaker PR flack, we'd like to thank the following automakers for enduring "mountain of antacids" and that "creeping sense of paranoia" necessary to keeping ones' wares totally under wraps until the sheets are pulled off the sheetmetal: Buick Avenir concept Chevrolet Bolt concept Ford GT concept Ford Mustang Shelby GT350R Ford F-150 SVT Raptor Hyundai HCD-15 Santa Cruz concept And while we're at it, we'd like to throw in an shout-out to Detroit's substantially revised and revitalized Cobo Center, and in particular, the redone Michelin media center, which is arguably the single best accommodations for writing show stories that we've encountered on the entire international circuit. Well done, everyone. Thank you, and keep the surprises coming. Auto News Detroit Auto Show Buick Chevrolet Ford Hyundai Volvo 2015 Detroit Auto Show
