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.

You want screens? The 2021 Cadillac Escalade infotainment system gives you screens

The 2021 Cadillac Escalade’s infotainment system shocked and awed when it debuted, but now weÂ’ve finally had a chance to live with both it and the giant SUV that surrounds it for a week. Sliding behind the triple OLED screens is like stepping into the tech-forward future Cadillac promised us. The 6.2-liter push-rod V8 under the hood says otherwise, but the interior technology has already arrived. There are three screens in total: a 16.9-inch touchscreen for the infotainment system, a 14.2-inch instrument cluster and a 7.2-inch touchscreen to the left of the cluster. All three are OLED displays, and just as you might expect, they are gorgeous to take in. None of the high-tech German luxury vehicles have screens this pretty. The Escalade's donÂ’t just look great, though. All three screens are quick to react and pop through functions/menus without a hitch. The only slop or delay in the whole system is when you go to turn the cluster's augmented reality (AR) camera on  — you wait one potato, two potato, and then the feed pops up. ItÂ’s a new take on GMÂ’s infotainment system as a whole. YouÂ’ll still be swiping side-to-side through an iPad-esque display of apps, but the UI is totally rethought and appears fresh. Icons are big and easy to press. Nothing is hidden off-screen at any point. It just makes good sense. 2021 Cadillac Escalade infotainment View 17 Photos Cadillac has found a way to better utilize its redundant scroll wheel, too. Though it's the same wheel as is on other models, this time the whole display changes to match the wheelÂ’s action when you use it. For example, the home screen turns into a revolving circle of apps that you twist through as soon as you twist the dial. It may take some getting used to, but the option between two different interfaces that both function well is a positive. Redundant combos of touchscreen and control wheel are common, but no one offers something like this.  Keeping a few physical buttons and an actual volume knob around to control the infotainment system is another thoughtful touch — same goes for the climate controls, which entirely consist of physical buttons. Despite the central instrument panel screenÂ’s prodigious size, you wonÂ’t actually find a whole lot buried in there. All of the trip settings and general car settings have been moved into the infotainment system itself.

Cadillac XT4 crossover to be built in Kansas City

Cadillac's upcoming XT4, a crossover we've previously known as the XT3 in a long series of spy shots of heavily camouflaged mules, will be built at General Motors' assembly plant in Kansas City on the same platform as the Chevrolet Malibu, Bloomberg reports, citing people familiar with the plan. That will give Cadillac another entry in the red-hot luxury crossover segment and, GM hopes, help to reverse a sales slump in the U.S. It'll also breath life into the Kansas City plant that makes the slow-selling Malibu, where GM cut a third shift last year, by sharing the assembly line between the crossover and sedan and defraying costs for each vehicle. The XT4 was known most recently as the XT3, with styling cues based on the Escala concept sedan from 2016. It's slightly smaller than the XT5, Cadillac's top-selling vehicle, and will also augment the full-size Escalade in Cadillac's stable of SUVs when it makes its expected debut later this year. Cadillac last week reported its second-highest-ever sales mark with 356,467 vehicles, an increase of 15.5 percent over 2016. But that mark papers over an 8 percent sales decline in the U.S. to 156,440 vehicles. The luxury brand is on a hot streak in China, where sales jumped 50.8 percent last year to 175,489 units.Related Video: Image Credit: Brian Williams Plants/Manufacturing Cadillac Chevrolet GM Crossover sales cadillac xt5 cadillac xt4 cadillac xt3
