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.

My year in EVs: 8 electrics that are changing the car industry

The year 2021 will go down as an inflection point in the auto industry’s transition to electric vehicles. It's when many much-anticipated models became reality. No longer sketches or sketchy prototypes, electric vehicles appeared from all corners with everything from the Lucid Air to Ford Mustang Mach-E changing how we think about transportation. I managed to drive a lot of them, and as I went through my notes, I realized IÂ’ve got a mini memoir of the seminal EVs of 2021. HereÂ’s my take on eight of them. Hummer EV Easily the most over-the-top EV I tested this year. The 1,000-hp super truck lived up to the hype with its domineering presence, stupendous power and simply being a reincarnated Hummer. I took it for a short spin on- and off-road at the General Motors Proving Grounds in Milford, Mich., and was impressed with the airy cabin, removable sky panels and expansive touchscreens. Yes, I crab walked, which felt like steering a pontoon boat, though I can see why it would be useful. Lucid Air Dream Performance The most beautiful sedan I tested all year, EV or otherwise. Unlike the futuristic Mercedes EQS — which is quite attractive — LucidÂ’s car is a blend of mid-century modern interior aesthetics and classic European exterior styling. When I walked up for my test drive, someone who IÂ’m pretty sure was comedian Jon Lovitz was sitting inside and taking it all in. As it sat in the valet of a hotel in a wealthy suburban enclave north of Detroit, the Lucid drew more attention than any of the Mercedes, Cadillacs or Lexus models passing by. The driving experience was enveloping. Starting at $169,000 for the Performance model (reservations are closed), the Lucid I sampled packed 1,111 hp and 471 miles of range. From the precise steering to the comfortable suspension, the dynamics were spot-on. It's a formidable product, and all the more impressive given itÂ’s LucidÂ’s first. Chevy Bolt EV The Bolt was the most pleasant surprise for me. It handled well, offered low-to-the-ground hot hatch dynamics and the steering was dialed-in. Adding a crossover variant for the new generation was a smart play. On a summer morning where I went to a first drive of the Ford Bronco at an off-road course, my hour-long commute in the Bolt was an enjoyable appetizer.  The Bolt was also my biggest disappointment due to its extensive recalls for fire risk. Ironically, I had the Bolt in my driveway when the initial recall went out for the previous generation (2017-19).

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.
