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

Best and Worst GM Cars

Oh yes, because we just love receiving angry letters from devoted Pontiac Grand Am enthusiasts, we have decided to go there. Based on a heated group Slack conversation, the topic came up about the best and worst GM cars. First of all time, and then those currently on sale, and then just mostly a rambling discussion of Oldsmobiles our parents and grandparents owned (or engineered). Eventually, three of us made the video above. Like it? Maybe we can make more. Many awesome GM cars are definitely going unmentioned here, so please let us know your bests and worsts in the comments below. Mostly, it's important to note that this post largely exists as a vehicle for delivering the above video that dives far deeper into GM's greatest hits and biggest flops, specifically those from the 1980s and 1990s. What you'll find below is a collection of our editors identifying a best current and best-of-all-time choice, plus a worst current and worst-of-all-time choice. Comprehensive it is not, but again, comments. -Senior Editor James Riswick Best Current GM Vehicle Chevrolet Corvette We were flying by the seats of our pants a bit in this first outing and my notes were similarly extemporaneous. When it came time to tie it all together on camera, I failed spectacularly. Thank the maker for text, because this gives me the opportunity to perhaps slightly better explain my convoluted reasoning. I chose the C8 Corvette because it's simply overwhelmingly good, and it's merely the baseline from which this generation of Corvette will be expanded.  While the Cadillac CT5-V Blackwing (more on that in a minute) is an amazing snapshot of GM's current performance standing and its little sibling so enraptured me that I went out and bought one, their existence is fleeting. Corvette will live on; forced-induction Cadillac sport sedans, not so much. So while all three are amazing machines when viewed in a vacuum, the Corvette stands above them as both a reflection of GM's current performance credentials and a signpost of what is to come. So, given the choice between the C8 and the 5V-Blackwing right now, I'd choose the C8. In 10 years, when the Blackwing is no longer in production and Corvette is in its 9th generation? Well, that might be a different story. Now, just pretend I said something even remotely that coherent when we get to the part of the video where I try to make an argument for the 5-V Blackwing as best GM car I've ever driven. Or just laugh at me while I ramble incoherently.

GMC unveiling 2021 Yukon, Yukon XL on January 14

UPDATE: We received a reply back from a representative at GMC confirming that the new Yukon will be revealed on January 14. The text has been updated to reflect this. General Motors is renewing its body-on-frame SUVs, and GMC's Yukon is next in line to receive a full makeover. It's scheduled to break cover on January 14 alongside the long-wheelbase Yukon XL. It's reasonable to assume we would have gotten our first glimpse at the next Yukon during the 2020 Detroit Auto Show had the event not moved to June. The new date is too close to the model's on-sale date, so GMC will unveil it during a standalone event held in Vail, Colorado, according to GM Authority. We reached out to GMC, and a representative confirmed that is indeed the reveal date for the full-size SUV. Spy shots suggest stylists took GMC's two biggest SUVs in a sharper, bolder direction. Both models share the same front end, which borrows styling cues like C-shaped headlights from the Sierra pickup. Brand-specific rear lights help the Yukon models stand out from their Chevrolet-badged siblings, the Tahoe and the Suburban, which hasn't always been the case. The standard Yukon and the Yukon XL will each grow in size, though there's no indication GMC's naming structure will change to reflect that; Yukon XXL admittedly doesn't have much of a ring to it. While we haven't seen the interior yet, we expect it's getting a generous serving of technology, including a new, touchscreen-based infotainment system. The larger exterior dimensions will clear up more space for people and gear, so average-sized adults will be able to fit in the third-row seats. The range-topping Denali variants of both models will return to satisfy those who crave sumptuousness. The sheet metal will hide much of the same hardware found under the Tahoe/Suburban duo, including an independent rear suspension added in the name of comfort and handling. Powertrain specifications should carry over, too, meaning the entry-level engine will be a 5.3-liter V8 rated at 355 horsepower and 383 pound-feet of torque. The list of options will include a 6.2-liter V8 with 420 horsepower on tap, and we're betting the straight-six turbodiesel available on the Bowtie-badged SUVs will also be offered at an extra cost. Rear-wheel drive and a 10-speed automatic transmission will come standard, and buyers will be able to pay extra for four-wheel drive. The next GMC Yukon and Yukon XL will go on sale halfway through 2020 as 2021 models.
