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.

GMC Hummer EV First Drive Review | True supertruck, for better and for worse

Right from the start, the 2022 GMC Hummer EV has been advertised with superlatives, mostly in reference to its specifications. GMC has even called it a "supertruck" in its own materials. And while we've received a taste of the truck before, only now have we finally got our hands on the production-spec model, and had the opportunity to drive it both off-road and on the street. What we've found is that the Hummer EV is undoubtedly a supertruck, much the same way that a Ferrari or a Lamborghini is a supercar. It totally delivers on its incredible capabilities, but there are compromises. And they're worth being aware of before plunking down the more than $100,000 a first-year Hummer will run you. That six-figure truck is the version we tested, the Edition 1, which actually rings in at $112,595. It's the only version in production for now, with lower trims coming in the next couple years. It's sold out, but many of the features will be available on the next highest trim level, the EV 3X. Among those features are the three motors, torque vectoring, “Watts To Freedom” launch mode, four-wheel steering, removable glass roof panels, 35-inch tires, Super Cruise, power rear window and MultiPro tailgate. In other words, although you can literally no longer order an Edition 1, you can still order a Hummer EV with nearly the same specification. This content is hosted by a third party.

No one can resist seeing what 1,000 horsepower and 1,200 pound-feet of torque will feel like. It's even a tad more torque in Watts To Freedom mode, which preemptively runs the cooling system to enable the additional twist. That mode allows the Hummer to hit 60 mph in 3 seconds, and the drama is dialed up with visual, audible and haptic cues. But even without engaging launch mode, the Hummer EV impresses and delights with its acceleration. In addition to pinning you to the seat, the entire truck squats in an exaggerated fashion. It's absurd, especially considering the truck's curb weight that surpasses a truly astounding 9,000 pounds. ThatÂ’s several hundred pounds more than the heaviest GMC Sierra HD 3500 diesel dually. Of course, that weight, as well as the nature of electric motors, means the party starts to calm down as the speed increases. The weight is noticeable in other areas, too.

2022 GMC Hummer EV dimensions, clearances and off-road features explained

There are two things that almost everyone immediately thinks of when they hear the word "Hummer." And they are size and off-road capability. Looking at the numbers on the 2022 GMC Hummer EV, it seems the electric pickup has literal truck loads of each. One of the most prodigious numbers is the truck's width. See those clearance marker lights on the roof? They aren't just there for style, they're required by law due its width. At 86.7 inches, it's just a bit wider than a Ford F-150 Raptor, which is itself 6.4 inches wider than a comparable F-150. The Hummer is also 5.5 inches wider than a GMC Sierra. Length is more reasonable at 216.8 inches, which is much less than a full-size crew cab pickup (a Sierra 1500 is 231.7 inches with its 5-foot-8-inch box or 241.2 with the 6-foot-6 one). It's even 3 inches less than the Raptor SuperCab and only 4.4 inches longer than a GMC Canyon with the standard 5-foot-2-inch box. In other words, the Hummer EV is roughly as long as a midsize pickup but is wider than a heavy-duty one.  What does that mean for the cabin? With 38.9 inches of rear legroom, it falls well short of a Sierra Crew Cab's 43.4, but it's important to remember that crew cab pickups have an overkill amount of limo-like legroom. The Hummer's amount is still 3.7 inches longer than a Sierra Double Cab and 3.1 inches longer than a Canyon Crew Cab. Headroom, which was rather pathetic in the old Hummer H2, is 38.6 inches in the back seat – less than both its GMC truck siblings, but not by much. In other words, there should be plenty of space back there. Note that GMC didn't indicate bed length, frunk volume, or importantly, curb weight. We will update this should we find out answers to any of those.  Although it's big, the Hummer has plenty of features to make it nimble off road, both traditional and high-tech. One of the primary features is the height-adjustable air suspension, which offers 13 inches of travel and automatically adjusts damping for driving conditions. It has three main levels, a lowered setting for Aero Mode that helps with improving highway energy use, a default height for the normal driving modes, and a higher setting for the off-road Terrain Mode.
