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

Malaise Era Junkyard Gem: 1979 Buick Electra Limited

In the fall of 1973, the Arab members of OPEC shut off the oil taps, and Detroit got busy making many of their full-sized land yachts a lot smaller. By model year 1977, the downsized fifth-generation Buick Electra was ready to go ... just in time for the 1979 Iranian Revolution to squeeze the supply of the black stuff even further. You won't see many of the 1977-85 Electras these days, but I spotted this faded but solid '79 Limited sedan in a Denver self-service yard last week. General Motors must have bought up the entire world's supply of blue velour around this time, because you'll see this stuff in just about every car they made for the following decade or so. By this time, GM was doing a lot of mixing-and-matching with engines from its various divisions, which meant you could buy an Oldsmobile 88 with a Chevrolet 350 V8 engine, a Chevrolet Monza with a Buick 231 V6 engine, or— as in this case— a Buick Electra with an Oldsmobile 350 V8 engine. Do you want to know how many horses this engine delivered to this 3,631-pound car? 155 horsepower out of 5.7 liters of engine displacement. Times were tough during the Malaise Era.

Buick Electra-L, Electra-LT concepts lead the Wildcat to production

Buick loves the Beijing Motor Show, and why shouldn't it? Working with its local partner, SAIC, the brand seems to saves up so much mojo for April in Asia and shows up with stunning designs. Here are another two takes on the brand's latest sheet metal philosophy, penned by the SAIC-GM Pan Asia Technical Automotive Center and riding on GM's Ulitum platform, the Electra-L sedan and Electra-LT wagon concepts. The Electra-L could be seen as a production version of the Wildcat EV concept from 2022 (not the Wildcat from 1985) that launched Buick's new design language. All the major forms and curves are there, so too the turbine-style wheels, but the fastback roof's been stretched to create adequate headroom for a quartet. The edges of the front fascia have been redrawn to be less aggressive and form a canvas for illuminated ornamentation. The four-door stretches 198.3 inches long on a 118.1-inch wheelbase, meaning less than an inch difference in both dimensions between the Buick and the new BMW i5. Power comes from a single motor on the rear axle making 342 horsepower. A battery of unknown capacity is claimed to be good for a 435-mile range under China's CLTC test loop. The light-sensing glass roof hovers over a rectilinear instrument panel with a floating main display and a retractable 7-inch screen for the front passenger, four pressure-sensitive "zero-gravity" seats wrapped in an eco-friendly fabric, and rear quarters with a small inductive cooktop for enjoying tea in the custom tea set.  SAIC and Buick had less to say about the Electra-LT. Looking like the Allroad version of the Electra-L, it's got fender extensions framing the "titanium metal armor" wheel design, an air suspension that can lift the body by 1.6 inches, and that roof box to broadcast its light adventure credentials. Fitted with the same basic interior layout as the sedan, the wagon might add a third row; the description says its "eConnect smart cabin system supports 7-screen interaction." We're not sure if something got left out of the powertrain description, though, as the Electra-LT said to be powered by a 342-hp motor on the rear axle while also possessing "independent four-wheel drive."    Two years ago, Buick said it would introduce five all-new EVs in China by 2025. The sedan is rumored to be headed to the Chinese market next year, a production version perhaps ready by the time of the 2025 Auto Shanghai.
