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

Junkyard Gem: 1982 Buick Riviera Diesel Coupe

After appending the Riviera name to various cars during the 1950s, Buick finally made the Riviera a model in its own right for the 1963 model year. Seven more generations of Buick's rakish personal luxury coupe followed over the next 36 years, but only one ever had an oil-burning engine available from the factory. Today's Junkyard Gem is one of those cars, a vividly purple '82 Riviera with 105 horses of Oldsmobile diesel power under its hood, found in a Denver-area self-service boneyard recently. Starting in the 1966 model year, the Riviera had been living on the same platform as the Cadillac Eldorado and Oldsmobile Toronado, both of which featured radical front-wheel-drive powertrains that used longitudinal V8s powering the front wheels via sturdy chains. However, despite the common platform, the Riviera alone kept the then-traditional front-engine/rear-drive setup, making it something of a corporate oddball for the next 12 years. Then General Motors decided to downsize the Eldorado/Toronado platform for the 1979 model year, and the Riviera got those cars' front-wheel-drive rig at the same time. Sales of the smaller Rivvy were strong, no doubt due in large part to certain geopolitical events that sent gas prices skyward and caused fuel rationing and gas lines. Back in the late 1970s and early 1980s, diesel fuel was much cheaper than gasoline in the United States. Mercedes-Benz and Peugeot had done reasonably well selling diesel-engined cars here during the 1970s, and so General Motors developed a diesel-burning version of the Oldsmobile 350-cubic-inch (5.7-liter) V8 engine. As was typical of naturally-aspirated automotive diesels of the time (every modern car's diesel engine is turbocharged), horsepower was miserable but torque was strong; the engine in this car was rated at 105 horses and 205 pound-feet. The 5.7 diesel first showed up in the Riviera for the 1981 model year. The base engine was a 4.1-liter version of the Buick V6, while the oil-burning Olds cost an extra $924 (about $3,206 in 2023 dollars). A comfortable and smooth-riding Riviera with the cheap fill-up price and long range of diesel sounded great, even if you had to line up with Freightliners and Peterbilts to get to a pump, but there were problems. Oh, so many problems! Oldsmobile's 350 V8 had been around since 1968 and it had proven to be both reliable and powerful.

The last Buick Cascada unceremoniously rolls off the assembly line

Motorists in the market for a new Buick Cascada need to act fast. Peugeot-owned Opel has built the last example of the drop-top model in its Gliwice, Poland, factory, and there's no replacement in sight. Buick announced the Cascada's demise in early 2019, and GM Authority learned the model went out unceremoniously. There's no indication that the final example received a commemorative plaque on its dashboard, or is headed to a private collection; photos of it aren't even available. The dealership who ordered it might not know it's about to receive the last specimen of the breed. As a non-luxury, front-wheel-drive convertible, the Cascada was marooned on an island that Buick's rivals abandoned halfway through the 2010s. The Chrysler 200 Convertible and the Volkswagen Eos were discontinued after the 2014 and 2015 model years, respectively. Landing in a class of one likely raised more than a few eyebrows in Buick's product planning division, but it was a semi-enviable position that helped the firm sell about 17,000 units of the Cascada between the 2016 and 2019 model years. It proudly pointed out about 60 percent of buyers were new to General Motors. Left-hand-drive examples of the Cascada were sold under the Buick and Opel banners. Right-hand-drive models joined the Vauxhall range in the United Kingdom, and they wore a Holden emblem in Australia. The four flavors were identical with the exception of some brand-specific trim pieces and powertrains. None will get a successor; the aforementioned carmakers are no longer operating under the same roof, and the global convertible segment is steadily shrinking.  The Cascada's multinational provenance made more sense before General Motors sold its Opel and Vauxhall divisions to PSA Groupe, the Paris-based carmaker that owns Peugeot, Citroen and DS. The French firm pledged to keep producing cars for Buick for as long as necessary, but the former sister companies tacitly agreed to stop co-developing vehicles. The sedan and station wagon variants of the Regal are now the only Opel-designed, PSA-built model left in the the Buick portfolio.
