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.

2022 GMC Hummer EV Edition 1 Prototype Drive Review | Let the supertruck wars begin

MILFORD, Mich. — Hummer is high on the list of vehicles we never thought would return. The gas-guzzling brutes met their demise more than a decade ago as the industry pivoted briefly to smaller cars and General Motors shed brands during its historic restructuring. Fast-forward to 2022, and HummerÂ’s revival is at hand thanks to yet another industry shift, this time to electric propulsion. ItÂ’s expensive, itÂ’s still huge and the numbers are eye-popping to the tune of 1,000 horsepower. America loves a comeback — but it loves trucks more. We briefly tested the 2022 GMC Hummer EV Edition 1 truck at the GM Proving Grounds 40 miles northwest of Detroit. Weeks from now, Hummers will start rolling off the line at GMÂ’s EV site, dubbed Factory Zero, in the Motor City. While the Hummer SUV will undoubtedly prove its worth, GM is leading with the pickup, ambitiously calling it a supertruck and eagerly touting its metrics and mojo-generating features, like CrabWalk, against the Rivian R1T, Ford F-150 Lightning, Tesla Cybertruck, as well as gas-powered off-roaders like the Ford F-150 Raptor and Ram 1500 TRX, plus various Jeep and Land Rover SUVs. (Here's our latest supertruck spec comparo). All of them have impressed us (save the Cybertruck, which only Jay Leno and a few others have driven), but the Hummer is formidable in its own right. For one thing, itÂ’s a Hummer. The negative connotations of the old Hummers melt away when thereÂ’s a 24-module Ultium battery pack powering three motors for a range of 350-plus miles on a single charge. The old model was divisive, but a lot of people paid a lot of money for them simply because they looked very cool. HummerÂ’s familiar grille makes it bold return on our tester that looms high on its 35-inch Goodyear Wrangler Territory MT tires. It certainly looks the part of a supertruck. The cabin is roomy and airy, with the removable sky panels letting in the bright fall morning. Hummer EV chief engineer Al Oppenheiser is our co-pilot for our test, and after a quick walk-through, weÂ’re off.  The first order of business is simply mashing the throttle. The Edition 1 serves up about 1,200 pound-feet of torque, and you can make use of all of that and the four-figure horsepower to hit 60 mph in about 3 seconds. We accelerate hard, blasting over some soft ground before things get a little squirrelly and can confirm the claimed time feels legit.

GMC's Hummer EV will offer several powertrain options

General Motors confirmed plans to resurrect the Hummer nameplate on a GMC-badged electric pickup, and it's beginning to release details about the drivetrain that will power the model. Speaking to investors, company president Mark Reuss announced buyers will have at least three drivetrains to choose from at launch. The few specifications that have already been announced are impressive. GMC quoted a three-second sprint from zero to 60 mph, at least 1,000 horsepower, and 11,500 pound-feet of torque, though that latter figure undoubtedly corresponds to wheel torque rather than the powertrain's basic output. Most truck buyers don't need Lamborghini-rivaling acceleration, and they'd rather not pay for it, so GMC will also offer more basic versions of its Hummer. "When we go to market, we'll have one-, two-, and three-motor versions offering different ranges, different performance, and different price points to meet customers wherever they may be. If the customer wants a basic package, we'll have that. If the customer wants true off-road capability, and towing capability, we'll have that, too," Reuss said. He stopped short of revealing additional specifications about each configuration. While that sounds expensive to develop and certify, Reuss explained General Motors is keeping costs in check by making the Hummer's powertrain as modular as possible. He compared the platform to an ice cube tray. Its overall dimensions are fixed, but people can choose how many rows they fill with water. What he's likely alluding to is a scalable battery pack whose capacity can be increased or decreased by adding or removing cell packs. As for the motors, we're expecting the entry-level, rear-wheel drive Hummer will come standard with a single motor mounted over the rear axle. The mid-range variant will likely gain a second motor positioned over the front axle to deliver through-the-road all-wheel drive, and the range-topping trim will receive individual rear motors (though they won't be integrated into the wheels) for jaw-dropping performance, and improved off-road capacity.  Economies of scale will come into play, too. While the Hummer is the only electric off-roader whose launch has been confirmed by General Motors, Reuss stated the company's other brands will benefit from it, too. "We'll have a complete lineup of EVs, including the [Hummer EV] and its stablemates," he said.
