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 recalls 3.8 million vehicles in North America due to braking issue

WASHINGTON — General Motors Co said Wednesday it was recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and that has been linked to 113 accidents and 13 injuries. The recall covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles. In late June, GM recalled 310,000 vehicles in Canada for the same issue. GM did not immediately explain why the Canadian recall occurred more than two months before it called back the vehicles in the United States. The recall was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted on Wednesday. The NHTSA opened a preliminary investigation into the issue last November, and said it had reports of nine related crashes and two injuries. It provided GM in July with additional field reports that prompted the automaker to open an investigation. GM said it could affect braking in "rare circumstances." The NHTSA said in a statement the "vehicles may experience brake boost failure, which would require increased brake pedal effort, leading to a hard brake pedal feel, and potentially increased stopping distance." GM said dealers will reprogram the electronic brake control module to improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Separately, GM said on Wednesday it is recalling 270,000 additional U.S. vehicles in three smaller recalls, including 177,000 2018 Chevrolet Malibu cars with 1.5L turbo engines because an error in the engine control module software may result in the fuel injectors being disabled.

2020 Cadillac XT5 makes its official debut, adding a new engine and improved tech

The 2020 Cadillac XT5 is here, and it’s new in some significant ways. To start, it gets a slightly revised look. We got a preview of it a month ago when Cadillac revealed the car in China, but these are official U.S.-specific photos now.  YouÂ’re looking at pictures of the XT5 Sport and Premium Luxury here. We mention this because Cadillac is continuing in its “Y” trim strategy of offering a Luxury, Premium Luxury and Sport version of their cars with noticeable design differentiation between each one. The Sport gets a darker appearance package with the XT4-like grille, as opposed to the Premium Luxury that is set to emphasize bright trim (i.e. chrome).  WeÂ’re expecting a noticeable change in the driving experience for the 2020 XT5, as the new base engine is the 2.0-liter turbocharged four-cylinder that debuted in the XT4. ItÂ’ll be making 237 horsepower and 258 pound-feet of torque in this application, just as it does in every vehicle GM is spreading it to. The 3.6-liter V6 is standard on the Sport (optional on Premium Luxury), and continues to make 310 horsepower and 271 pound-feet of torque. Both engines are paired with nine-speed automatic transmissions now — the V6 was paired with an eight-speed previously.  Cadillac has also spent some time with the suspension, giving the non-Sport trims “revised front struts and driveline enhancements to improve ride comfort and road isolation.” We like the sound of that. Then, the Sport trim is legitimately sportier than the Luxury trims. Cadillac has fitted its continuous damping control adaptive suspension, given it quicker steering, standard all-wheel drive and standard 20-inch wheels. All that should make it slightly more lively through the twisties. A smattering of tech updates are coming onboard for 2020. Cadillac added its rotary controller that lets you control the updated infotainment system via that device or through the touchscreen. Available wireless phone charging, revised USB ports and USB Type-C ports come on the 2020 XT5. Then youÂ’ll notice new interior color and trim gracing the interior surfaces, as well. Cadillac says there are more “authentic materials” than before, so hopefully that means less plastic. What Cadillac made no mention of in its release, is Super Cruise. ItÂ’s going to be coming to the recently revealed CT5 and CT4-V sedans, but Cadillac doesnÂ’t seem particularly keen to get it on the crossovers yet.
