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

GM removes start/stop from full-size trucks and SUVs with V8 engines

GM is removing start/stop technology from a number of its popular full-size SUVs due to the ongoing chip shortage. This follows the removal of cylinder deactivation technology from some of its trucks, which was also due to the chip shortage. GM Authority first reported the news, but we’ve just confirmed everything with a GM spokesperson.  The following 2021 model year vehicles will be affected: Chevy Tahoe, Chevy Suburban, GMC Yukon, Cadillac Escalade, Chevrolet Silverado 1500 and GMC Sierra 1500. Only versions of those vehicles built with the 5.3-liter V8 or 6.2-liter V8 and mated to the 10-speed automatic will have the tech removed from them. Only vehicles manufactured on or after June 7 will be affected. “By taking this measure, it will enable us to continue production of our high-demand full-size SUV and pickups as the industry continues to rebound and strengthen,” GM said in a statement. Those who ultimately buy one of these vehicles without start/stop technology will receive a $50 discount off MSRP for their troubles. Losing this fuel-saving tech could be a big negative for some, but we know many folks turn it off anyway. Not having to press the button to deactivate start/stop every time could actually be a positive if youÂ’re part of the camp who does that already. 2021 Cadillac Escalade Sport Platinum View 27 Photos On the downside, GM says “most of the affected vehicles will experience a minor reduction in fuel economy.” We donÂ’t have revised window stickers in hand to know how each model will be affected, but any 1 mpg reduction will be rather impactful for vehicles rated as low as these trucks already are. Any reduction will be seen in the city mpg rating, so take the kind of driving youÂ’re going to be doing into account before purchasing. When it comes to greenhouse gas compliance rules, GM says it doesnÂ’t foresee this impacting the companyÂ’s average fleet score. It also intends to begin adding start/stop back to these models as soon as possible, but there will be no retrofit effort made to fit the tech to vehicles already built without it. “Our supply chain organization continues to make strides working with our supply base to mitigate the near-term impacts of the semiconductor situation,” GMÂ’s statement reads. “GM continues to leverage every available semiconductor to build and ship our most popular and in-demand products, including our highly profitable full-size trucks and SUVs for our customers.

2024 GMC Acadia gets bigger, goes entirely turbocharged

For an entire generation now, the GMC Acadia, the brand's largest unibody SUV, has sat in an unusual zone in between the typical midsize two-row and large three-row segments. But the completely redesigned 2024 Acadia is stepping confidently into the latter camp, growing to roughly match its cousin, the also fully redesigned 2024 Chevy Traverse. And adding to its greater size and performance, the Acadia brings unique exterior and interior design. The size increase is impressive. The wheelbase has grown 10.6 inches, overall length by 8.4, and overall height by 3.2. GMC claims this has increased cargo space by 80% and second-row seat room by 27%. These changes all make it about the same size as the Chevy, too, instead of a smaller option.  This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. That doesn't mean the two look the same, though. The front fascia clearly borrows heavily from the GMC Sierra 1500 with a tall grille and C-bracket headlights. The flanks really depart from the aggressive shape of the Traverse. It also skips the fat C-pillar. GMC designers noted they specifically worked to reduce the size of that pillar, in part to improve visibility for third-row passengers. Conversely, the D-pillar is relatively large and is finished in body color to reveal it. But to keep it from looking overly large, there's a black plastic panel that helps give the rear window a bit of a wraparound effect. The taillights also have a gloss black panel to blend them into the rear window area and reduce the visual mass of the hatchback. The interior is the biggest differentiator between the Traverse and Acadia, though. The entire dashboard is unique to the Acadia. The 11-inch instrument display sits under a cowl that extends horizontally to meet the unique vertical 15-inch infotainment screen. That screen overlaps a squared-off, horizontal dash design, and it's flanked by vertical air vents. The Acadia picks up a column-mounted shifter, too, freeing up space for storage in the center console. There are practically no parts directly pulled from other GM products. And unlike GM's upcoming EVs, the Acadia will have Apple CarPlay and Android Auto functionality. Individual Acadia models even have unique features. The luxury Denali trim and off-road focused AT4 trim both return. The AT4 stands out the most with an extra inch of ground clearance in part from the all-terrain tires on 18-inch wheels.
