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.

Super Bowl car commercials: Follow along as we riff on them live

Join Autoblog editors Sunday starting around 6:30 p.m. ET as we react to all of the car commercials during the game. We know Hummer, Porsche, Hyundai and others will have splashy ads, and naturally, there's usually a few surprises. Whether you're a Chiefs or 49ers fan — or don't care about football — the commercials are always a highlight. And for us, the car spots are the most intriguing. Weigh in with your own thoughts in the comments section. Let's kick off.   FIRST QUARTER Editor-in-Chief Greg Migliore liveblogs the first quarter. F9 We'll count this as a car commercial. The latest edition of the Fast & Furious looks like it well, will have cars. We'll punt on further comment. PORSCHE I like it. Creative. Sort of a Night at the Museum feel. The guards stage a theft and then a car chase. The Taycan looked good. Get fired up — the future for Porsche is electric. The spot is meant to illustrate how fun that can be. I don't need any convincing.    SECOND QUARTER Associate Editor Byron Hurd is liveblogging the second quarter.  HYUNDAI Hyundai checked in super early with their Sonata "Smaht Pahk" commercial, which manages to score points for being both cute and clever while also being a fairly good commercial in a vacuum. We saw it last week, so there were no surprises here, but we enjoyed it nonetheless.  Fun note: If you go to the Sonata landing page on Hyundai's web site, you can choose "plain old English" or "the Boston way" for your language; the latter will translate the page. Enjoy.  FORD Hi ho, West Coast Editor James Riswick here. Apparently, the guys in Detroit didn't get the Mustang Mach E ad featuring Idris Elba and a whole boat load of awesome old Mustangs. Pretty sure it's bound to be viewed the exact same way as the car itself: traditionalists will be aghast, while non-car people will be intrigued by a new, all-electric, crossover version of one of the few cars they've heard of.  GENESIS They're coming more rapidly now. Genesis gets some love thanks to Chrissy Teigen and John Legend; this was another known quantity, but Hyundai's luxury brand managed another solid entry here thanks to its choice of stars. Teigen and Legend got the chance to throw back to the latter's "Sexiest Man Alive" honors, which Teigen often teases him for. Another solid all-around spot.  GMC/HUMMER Are there just no surprises left? Don't tell me; I know the answer. LeBron James fronts the revived Hummer, which will be an EV sold as a GMC.

General Motors has tried to cast Hummer in a greener light before

Rumors claim General Motors will resurrect the Hummer name on an electric pickup truck by 2022, and GM allegedly will preview the model with an ad starring basketball star LeBron James during the 2020 Super Bowl. If accurate, the move would represent a stunning 180-degree turn for a nameplate long associated with war-like gas-guzzlers. It wouldn't be the first time the automaker has tried to cast Hummer in a greener light, however. In 2004, when mass electrification looked as realistic as George Jetson's flying car, Hummer collaborated with Quantum Technologies to build a one-off H2 SUT named H2H powered by hydrogen. Engineers modified the stock H2's 6.0-liter V8 to run on compressed hydrogen stored in three carbon fiber tanks, and added a supercharger to offset the loss of power. The eight-cylinder made 180 horsepower, compared to 325 horsepower in the gasoline-powered model, and the truck's 12-pound hydrogen storage capacity gave it a 60-mile range. "The H2H was created for two purposes. It brings focus and attention to the journey to a hydrogen economy, and it will provide GM with key learnings on hydrogen storage, hydrogen delivery systems, and hydrogen refueling infrastructure development," explained Elizabeth Lowery, the company's then-vice president of environment and energy. She emphasized the H2H's experimental vocation and said there were no plans to bring it to production. Actor, then-California governor, and devout Hummer fan Arnold Schwarzenegger celebrated the H2H as a vision of the future after taking it for a spin. It didn't have much of a future, as it turns out, and it remained a prototype. Fast-forward to 2009, less than a year before Hummer shut down after the Chinese government vetoed a proposed sale to Sichuan Tengzhong Heavy Industrial Machinery Company. General Motors teetered on the brink of bankruptcy, it had much bigger worries than Hummer's fuel economy, so the task of making a greener truck fell into the lap of suppliers. FEV and Raser joined forces to build a plug-in hybrid prototype based on the H3. Its powertrain was built around a turbocharged, 2.0-liter EcoTec engine related to the unit found in the Chevrolet HHR SS and the Pontiac Solstice GXP, among other cars. In this application, it powered a 100-kilowatt generator that zapped a 268-horsepower electric motor into motion. Output traveled through the H3's stock four-speed automatic transmission and four-wheel-drive system, including the transfer case.
