GMC Hummer EV recalled over improperly sealed battery pack

Over 700 units of the GMC Hummer EV built during the 2022 and 2023 model years will be recalled due to an improperly sealed battery pack that lets water in. The firm issued a stop-delivery order at the same time as the recall, and it hasn't found how to fix the problem yet. Assigned recall number 22V-771 by the National Highway Traffic Safety Administration (NHTSA), the campaign includes 735 examples of the Hummer EV and 89 units of the BrightDrop Zevo 600 van. These two vehicles are pegged on opposite ends of the automotive spectrum, but they're affected by the same problem: "the high-voltage battery pack enclosure in some of these vehicles may not have been properly sealed," GMC notes, adding that "flanges on the battery pack enclosure may not have been properly primed or electrocoated." Water can wreak havoc in a high-voltage battery pack. GMC told NHTSA that it has found three EVs with this problem: an internal test vehicle that lost power while driving and two customer-owned vehicles that wouldn't start. As of writing, the firm is not aware of any accidents, injuries, or fires related to the issue, and GMC estimates that only about 1% of the recalled EVs are affected. GMC began notifying dealers of the recall in October 2022, and it plans to start reaching out to owners on November 28, 2022. However, a fix hasn't been found yet. In the meantime, the company issued a stop-delivery order and asked dealers not to attempt their own repairs. This isn't the Hummer EV's first run-in with water-related problems. In August 2022, General Motors voluntarily recalled 424 units of the Hummer EV and the Zevo 600 van due to a high-voltage connector that can prematurely corrode. The problem also let water leak into the battery pack, though it sounds like fixing it was reasonably straight-forward and involved applying sealant to the connector.

5 things we love about the 2019 GMC Sierra AT4

NEW YORK — The 2019 GMC Sierra AT4 proves that GM's upmarket truck and SUV brand is getting serious about offering rough-and-tumble capability to rival the Ford F-150, Toyota Tundra, Ram 1500 and Nissan Titan. Until the Sierra AT4 rolled onstage at a media event in lower Manhattan, prior to this year's New York Auto Show, the GMC brand had been more focused on luxury touches like fancy chrome wheels and posh interiors — no surprise, considering the upscale SLT and Denali trim levels account for the vast majority of GMC sales. So now GMC wants to get muddy and adventurous? Well, yes and no. The AT4 adds hardware that'll take truck buyers off the beaten path, though this GMC isn't anywhere close to being a Spartan, no-frills work truck. To better explain, let's look at five key features we love about the 2019 GMC Sierra AT4: More than stickers and chrome The Sierra AT4 isn't a cynical marketing ploy, there is some true all-terrain toughness built into this pickup truck. A factory-installed lift kit raises the AT4 by two inches, while Rancho monotube shocks, a locking rear differential, a two-speed transfer case and standard all-wheel drive prove this GMC can dare to venture off paved surfaces — though you might risk getting mud and muck on the truck's handsome 18- or 20-inch alloy wheels. Power and economy The Sierra AT4 comes standard with a 5.3-liter V8 coupled to an eight-speed automatic transmission. In the standard Sierra 1500, this engine produces 355 horsepower. GMC didn't mention engine specs here in New York, though it's possible the AT4 might get a small power bump. This engine should be plenty for most truck buyers, though GMC offers two tempting alternatives. These include a turbo-diesel 3.0-liter inline-six, along with a 6.2-liter V8. Both motors are paired to stop-start fuel-saving systems, along with a new 10-speed automatic transmission. Carbon fiber cool factor The GMC Sierra's available carbon-fiber cargo bed, called CarbonPro in GMC-speak, trims 62 pounds of weight, as compared to a traditional all-steel bed. This slick feature uses carbon composites for interior panels and, judging from GMC's videos of burly bricks and huge hammers being thrown into a CarbonPro cargo bed, it should prove more than up to the task of ... well, having someone throw bricks and hammers into the cargo area.

The 2017 GMC Yukon XL Denali: Not just for the fertile set

I have a sis whom I've nicknamed "The Vickster." She is a beautiful Amazon, 6'1 on a good day and is the mom to a singleton. So why would my sis need to own a GMC Yukon XL Denali when she doesn't have a brood? Well to this I say, is there a written rule somewhere that states behemoth SUV's must be solely purchased by, you know, school-run moms? I think not! Even though the 2017 GMC Yukon XL Denali is tanker-sized and can swallow up to nine passengers, it has road presence and supreme luxury to boot which is a real draw for not just the fertile set. The Yukon XL Denali is an in-your-face kind of vehicle, and it was all in mine. The monolith has a presence, there's no denying, and even though it is big from every angle, it is far from odious. The stately looking ride has nicely defined slabs of metal, boxy proportions that make you look as it glides down the highway. Giving the Yukon XL my front-to-back once over, I liked its imposing mesh grille, nicely placed chrome accents and badges, riveting upsized wheels, and attractive high-intensity discharge (HID) headlamps and LED rear tail lamps. Once I settled into the cavernous and swanky realm of leather and mellow accent lighting that makes up the Yukon XL's interior, I then realized why "The Vickster" opted for this vehicle. The SUV's interior design is not overdone, no excessive bling to the point of blindness! Tasteful appointments on the Yukon XL include soft-touch leathers, aluminum trim, wood inlays, La-Z-Boy comfy seating in the first two rows (2nd-row power-release fold-and-tumble bucket seats); and thankfully, the non-gizmos overkill command center has large and ergonomically comfy controls. Space for a leggy crew is more than ample in the first and second rows. The SUV's available power folding, third-row fold-flat seats, however, are not exactly cut out for those who have gone past middle school as the seating is less bolstered and a little too close to the floor. Loved the wide and cushy center console that is not only spacious enough for hanging folders or a laptop but most importantly, it's elbow-friendly! Technology on the Yukon XL did not disappoint—particularly with the available built-in 4G Wi-Fi Hotspot for up to seven devices that kept me connected wherever I roamed.
