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.

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.

An all-electric Hummer is reportedly under consideration at GM

GM is reportedly considering a return to the Hummer brand, but not in the traditional Hummer way. No, a report from Bloomberg says that GM is mulling over the idea of building an electric Hummer. The report cites unnamed sources within GM, as the folks prefer not to be named due to the private nature of the conversations. At this point, Bloomberg characterizes the Hummer talks as preliminary discussions. GM is figuring out how it wants to organize its future electric trucks and SUVs, and Hummer is a part of those discussions. Just as anyone would expect, Hummer could be used to profit off the current demand for rugged and tough vehicles. Mark Reuss didn't commit either way to a Hummer revival when asked by Bloomberg. "I love Hummer. I don't know. We're looking at everything," Reuss said. Other GM sources said that the company sees an opportunity to compete with Jeep for off-road vehicles that have creature comforts commanding high premiums. The report states that designers have done work with Hummer concepts, experimenting with Hummer styling to implement it on GMC-branded products, too. There's also the question of whether an electric Hummer is a smart move to begin with. Folks bought up Hummers before because they're big, brawny, good off-road, and gas was cheap. Gas is relatively cheap today, but attitudes around cars that achieve 10 mpg have changed. Rivian thinks that consumers are interested in premium electric SUVs and trucks, and the hype around that company is real right now. An electric Hummer would undoubtedly go after the same space as the Rivian R1S. The number of people willing to drop over $70,000 on an electric adventure vehicle is still untested, though. Even if GM did give an electric Hummer project the green light, we're still years away. We know GM is currently in development of an electric pickup truck platform, but that doesn't mean it's anywhere close to production. We haven't seen a new Hummer since GM halted sales of the brand in 2010. The recession and high gas prices drove sales down so low that Hummer declared bankruptcy in 2009, but GM still kept the brand in its portfolio. It's hard to think of a better time than the SUV and crossover hoopla of today to introduce something like an electric Hummer, but until we hear something more substantial from GM, the vehicle is going to remain a rumor.
