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

2017 Buick LaCrosse an evolution of sharp Avenir concept

After years as a bloated, uninspiring, but comfortable near-premium sedan, Buick has taken the wraps off a leaner, lither, far more stylish LaCrosse. The third-generation model has just made its debut at the 2015 Los Angeles Motor Show. While there's a lot to talk about, let's first address the new, Avenir-inspired sheetmetal. The fascia is basically the concept car smoothed over into production form, featuring the same winged trishield. In place of the chrome-trimmed waterfall, the LaCrosse gets a blacked-out, recessed grille with a chrome surround. It looks good in photos but it's better in person, adding a real sense of complexity and depth to the front end. The headlights and lower fascia, meanwhile, adhere closely to the concept. The same cannot be said of the LaCrosse's tail. While the taillight lighting pattern is similar, the overall shape of the lighting element is radically different, refining the design featured on the back of the Regal. Also gone, sadly, is the Avenir's boattail rear deck. Instead, the LaCrosse gets a small rear deck that curves up into a pleasant duckbill spoiler. The rest of the tail is pleasantly restrained. Perhaps the weakest point is the profile, where Buick has instituted a "split-spear" design, featuring a strong shoulder line above the rear wheel well, which sits below an even stronger character line that curves down and towards the front of the car. It strikes us as just a little too much, like the Impala. Underneath that sheetmetal, Buick has managed to trim nearly 300 pounds of body fat, nearly half of which came from the vehicle's actual structure. That 300 lbs, according to Buick's engineers, is equivalent to a Kenmore side-by-side refrigerator, in case you needed a helpful comparison. Despite the weight savings, Buick has upped the torsional rigidity for this new model by 15 percent. The LaCrosse's cabin features a strong, cockpit-like design, with a high, floating-bridge center console. This is possible due to Buick's adaption of the Electronic Precision Shift system, introduced earlier this month on the new Cadillac XT5. Despite the new-fangled console design, Buick's retained the wraparound cabin style introduced on the second-gen model. Based on a quick crawl around the interior, space is great in front, although ingress in back is somewhat difficult due to the roofline. You're probably wondering why we haven't said anything about the mechanicals just yet.

Junkyard Gem: 1990 Buick Reatta Coupe

During the 1980s, General Motors worked hard to woo back American car shoppers who had defected to European luxury brands. Swanky interiors, futuristic electronics and Europe-influenced styling found their way into quite a few GM models during the second half of the decade. Pontiac had the 6000 STE, Oldsmobile offered the Toronado Trofeo, Cadillac sold the Turin-Hamtramck-built Allante, and Buick produced the sporty Reatta two-seater. Just under 22,000 Reattas were built during the 1988 through 1991 model years, and today's Junkyard Find is the fifth example I've found during my junkyard travels. The Reatta was the most expensive 1990 Buick, priced at $28,335 for the coupe and $34,995 for the convertible (or about $65,895 and $81,380 in inflation-adjusted 2022 dollars).  For that kind of money, American car shoppers in 1990 could get a BMW 325i in coupe or convertible form for $24,650 or $33,850. They could get a Saab 900 Turbo convertible for $32,995 or an Audi Coupe Quattro for $29,750. Each of those European competitors had sophisticated overhead-cam engines and grippy suspensions, but the Reatta was built on a shortened version of the chassis that went under the Barcalounger-esque Buick Riviera and its engine was the old-timey pushrod Buick V6. The 3.8-liter Buick V6 had been made quite reliable and acceptably smooth by the time this car was built, and it made 165 horsepower (just three fewer than the BMW 325i), but Buick salesmen didn't have much to brag about when showing this engine compartment to a 35-year-old youngster who had just driven a Saab 900 Turbo. The antiquated engine was problem enough, but the lack of a manual transmission served to chase off additional potential buyers. A four-speed automatic was mandatory in every Reatta. Just in case some traditional (i.e. Greatest Generation members) Buick customers might consider this glamorous two-seater, Buick scared them off with the Reatta's video-game-style digital dash and its way-ahead-of-its-time Graphics Control Center touchscreen interface. You can't win! The Graphics Control Center hardware has been grabbed from this dash (the components also fit optioned-up Rivieras and Trofeos of the same era, so junkyard shoppers pull them for resale). Naturally, a Reatta owner would want a hardwired car phone. If you really wanted to be cool in the early 1990s, you bought a Chrysler product with the amazing VisorPhone.
