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.

Hummer EV could be part of GM's move into electric trucks and SUVs

WASHINGTON/DETROIT — General Motors plans to build a new family of premium electric pickup trucks and sport-utility vehicles at its Detroit-Hamtramck plant beginning in late 2021, possibly reviving the imposing Hummer brand with some of them, several people familiar with the plans said. The so-called BT1 electric truck/SUV program is the centerpiece of a planned $3 billion investment in the Detroit-Hamtramck plant to make electric trucks and vans, and part of a broader $7.7 billion investment in GM's U.S. plants over the next four years, according to a proposed labor deal between the automaker and the United Auto Workers union. The investments were made public by the UAW on Friday, but no details were provided. The investment would move the automaker into a part of the EV market that is largely untested and where GM has a higher likelihood of turning a profit, analysts said. "It makes perfect sense to hit the high end of the market in order to generate some revenue that might actually turn a profit," Auto Forecast Solutions vice president of global vehicle forecasting Sam Fiorani said. GM is mirroring the approach electric carmaker Tesla took by starting in the high end and then moving down the price ladder, he said. That is important for a company who previously tried to sell the plug-in electric hybrid Chevrolet Volt and all-electric Bolt cars at lower prices and higher volumes, but failed to sell enough to make those efforts profitable, Fiorani said. The UAW's 48,000 GM hourly workers are scheduled to vote next week on the proposed contract that would end a monthlong strike that analysts say has cost the No. 1 U.S. automaker about $2 billion in lost profit. GM's BT1 program includes an electric pickup for the GMC brand and an electric SUV for Cadillac, both due in 2023, the sources said. Before then, GM plans to begin low-volume production in late 2021 of the first BT1 model, a pickup, under a different brand, the source said. A performance variant of the pickup will be added to that brand in 2022, followed by an electric SUV in 2023. One of the sources said the Hummer name is "under consideration," but a decision has not been finalized. The pickup is codenamed "Project O." Bringing back the Hummer name would take advantage of a still strongly recognized brand name, Fiorani said.

Mil-Spec M1-R First Drive Review | The ultimate Hummer H1 gets better

In 2018, we got our first introduction to Mil-Spec, a company that sought to do to Hummer H1s what other resto-mod companies like Singer and Icon have done to other classic cars. Its initial run of hopped-up Hummers showed quite a bit of promise with an array of mechanical upgrades, including a particularly potent and entertaining diesel engine, plus major improvements to interior livability and luxury. As good as the initial trucks were, Mil-Spec wanted to do even better. It focused on details such as better materials and ergonomics for what it’s calling the second-generation of restored H1s. And all those upgrades are on display in the M1-R, which takes the second-gen M1 and adds some pretty extreme customer-requested modifications. @autoblog WhatÂ’s that? Oh nothing, just a Mil-Spec M1-R rolling on by ##autoblog ##hummer ##m1r ##custom ##fyp ? original sound - Autoblog As with all Mil-Spec Hummers, the M1-R received a comprehensive restoration, taking the body and frame down to bare metal. It was recoated in a durable bedliner-style material made with bits of Kevlar. This particular one was given a tint to make it look like one of the factory H1 colors, Competition Yellow. Steel off-road bumpers, a front brush guard, rear tubular tire rack, fender flares and door panels finished in plain black add contrast and help give it a more rough-and-tumble look. The simple and rugged 20-inch Black Rhino wheels look right at home on the truck, too, especially wrapped in the 38-inch off-road tries. Most of the improvements in the second-gen M1 are found within the cabin. As before, every upholstered surface is made of leather, in this case with diamond stitching that the customer requested. ItÂ’s all done in-house (fun fact, Mil-Spec is now also doing upholstery for private jets). Virtually every non-upholstered surface is made from machined aluminum. That includes the steering wheel, climate control knobs, air vents, window switches, turn signal stalks, even the custom-made ignition key. They all look and feel superb with hefty weight and crisp edges. The toggle switches are a particular treat and return a light, mechanical click with each press. Some of them are a little tough to reach as a result of the HummerÂ’s strange interior layout, but that would be the case even in a stock Hummer. These aluminum pieces are a massive step up from the plastic rocker switches and air vents used on previous Mil-Spec Hummers.
