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 Rivian R1T vs. 2022 Ford F-150 Lightning vs. GMC Hummer EV Pickup | How they compare on paper

The 2022 Rivian R1T has arrived, ushering in the era of the production electric pickup truck. The Rivian reviews are in, and spoiler alert: They're pretty good. Curious how the new battery-powered truck stacks up to its forthcoming competitors? Well, you've come to the right place. Rivian beat all of Detroit's big automakers to market in the half-ton segment, but probably not by the margin the startup would have liked. Ford's answer is the F-150 Lightning, which is due to enter production early next year, coming hot on the heels of GM's first entry into the space – the GMC Hummer EV pickup – which is scheduled to come off the line late this fall. While all three are pickups, they're aimed at distinctly different buyers, as a perusal of their specifications will reveal. Let's have a look, shall we?   Disclaimer: Before we dive in on this one, we'd like to note that while we've made our best effort to verify the specs provided, the Rivian is brand-new and the others are still in the prototype phase. Some of these figures may be inaccurate or may simply change before production. This is all hypothetical until you can actually cross-shop them anyway, right? Cool. End disclaimer. Let's start with the powertrains. They're all battery-electric trucks engineered on a modular rear-wheel-drive configuration engineered to accommodate (theoretically, anyway) up to four electric drive units. Rivian actually makes the most use of this with a quad-motor setup producing 835 horsepower and 908 pound-feet of torque with its high-output initial model. GMC's three-motor Hummer has the R1T beat with its estimated 1,000-horsepower output, while Ford's (also three-motor) comes in with a far more modest 563 horses. This is an excellent illustration of our above point that these are not all engineered for the same crowd. Ford's F-150, which comes in at a lower price point, is meant to be far more mainstream, as its power output suggests.  This theme continues when we look at the dimensions. Despite the image "Hummer" may conjure, GMC's entry actually needs the shallowest parking space. The Rivian is right behind it, with the work-truck-spec Ford extending more than a foot longer than either. What the Hummer lacks in length, it makes up for in girth. It's the widest by a good 5 inches. The Rivian is only slightly pudgier than the F-150, but it's much closer at that end of the scale.

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.
