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.

2023 Detroit Auto Show Editors' Rankings

The 2023 Detroit Auto Show was back in its traditional location, though in its fall spot in the calendar, and it was another pretty quiet event. By our count, only five new models, or model lines, were revealed and brought to the floor; all of which came from Detroit's own car companies. Still, some of them were quite significant, and the types were diverse. Naturally, we also had our favorites. So take a look to see how we ranked the reveals of the Detroit Auto Show. 2025 Cadillac CT5 View 15 Photos 5. 2025 Cadillac CT5 The refresh for the 2025 Cadillac CT5 is no great revelation, because it doesn’t have to be. An already solid, attractive design means only light tweaks were made to its appearance, and the new front fascia and redesigned lights just make the CT5 just that much more aggressive. So what was missing from the current model? Apparently, the answer was a gorgeous 33-inch curved LED display serving as both infotainment and instrument cluster. It has touchscreen capability to both the right and left sides of the steering wheel, and provides 9K resolution. Update some of the safety and driver assist tech, and — boom — the CT5 is properly modernized. Now bring on the updated Blackwing. –Senior Editor, Green, John Snyder 2024 Jeep Gladiator Live View 10 Photos 4. 2024 Jeep Gladiator Jeep carved out plenty of time for what is essentially a no-brainer mid-cycle refresh, but thereÂ’s one among us who is easily swayed: Me. I dumped the maximum number of points allotted on the 2024 Gladiator with only three words of explanation: "I like Jeeps." But this is kind of a big deal. The Gladiator pulled a lot of weight for Stellantis during the pandemic by providing an alternative to pickup buyers while Ram dealers were scraping the bottom of the supply barrel. To be fair, we're probably giving the Gladiator a bit of advance credit here for its promise to deliver a 4xe variant in 2025, but who else is talking about their PHEV pickup plans? Your move, Ford. –Associate Editor Byron Hurd. 2024 GMC Acadia AT4 View 17 Photos 3. 2024 GMC Acadia The 2024 GMC Acadia is the one reveal from this yearÂ’s Detroit Auto Show that was actually a totally new vehicle, and as far as three-row SUVs go, GMC aced it. The exterior has its own personality separate from its Chevrolet Traverse twin. Its AT4 trim is legit with more ground clearance, a torque-vectoring rear diff and sweet orange marker lights on the fenders.

GM extends vehicle production cuts into mid-March due to global chip shortage

DETROIT — General Motors said on Tuesday it was extending production cuts at three North American plants until at least mid-March due to the global semiconductor chip shortage, while vehicles at two other factories would only be partially built. GM, whose shares dipped 1% after the announcement, did not disclose the impact volumes or say which supplier and vehicle parts were affected by the chip shortage. But it said it would focus on keeping production running at plants building its highest-profit vehicles, full-size pickup trucks and SUVs. GM said it intended to make up as much lost production as possible once the shortage chip eased. "Semiconductor supply remains an issue that is facing the entire industry. GM's plan is to leverage every available semiconductor to build and ship our most popular and in-demand products," GM spokesman David Barnas said. GM said it was extending downtime at its U.S. plant in Fairfax, Kansas, its Canadian factory in Ingersoll, Ontario, and its Mexican facility in San Luis Petosi until mid-March when it would reassess the situation, he said. In addition, GM would build but leave incomplete for final assembly vehicles at Wentzville, Missouri, and its Mexican plant at Ramos Arizpe. GM vehicles affected by the idled plants include the Chevrolet Malibu sedan, Cadillac XT4 SUV, Chevy Equinox, and GMC Terrain SUVs. Vehicles to be left incomplete for now included the Chevy Colorado, GMC Canyon pickups and Chevy Blazer SUV. This week, GM had said it was idling the three factories where it has now extended downtime and said it would halve production at a plant in South Korea. The chip shortage has affected many automakers, including Toyota, Volkswagen, Stellantis, Ford, Renault, Subaru, Nissan, Honda and Mazda. Asian chipmakers are rushing to boost production but say the supply gap will take many months to plug. German chipmaker Infineon said the shortage would get worse in the near term. The chip shortage is expected to cut global output in the first quarter by more than 670,000 vehicles and last into the third quarter, IHS Markit said. AutoForecast Solutions estimated total lost production this year could reach 1 million vehicles. Honda and Nissan said on Tuesday they would sell 250,000 fewer cars in total this financial year due.
