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 could have had the Chevrolet Avalanche's Midgate

One of the many rumors swirling around the GMC Hummer EV claimed the truck would resurrect the Midgate inaugurated by the original Chevrolet Avalanche. Although we now know there's no way to fully knock down the partition between the cab and the cargo box, the firm revealed the rumor wasn't entirely false. "There was [a Midgate] early on. We opted for the functionality of the drop glass in the back. With the package layout and things like that, it was not advantageous to pursue that one. And, the five-foot bed was kind of the industry standard in regards to price of entry in that segment," explained John Mack, the Hummer's exterior design management, during an interview with Muscle Car & Trucks. The Hummer will go on sale with a five-foot box, and it doesn't sound like a longer bed will be available, so a modern version of the Midgate would have made the model more versatile by giving users the ability to fold down the partition behind the rear seats to carry bulky items, like plywood and ATVs. It's a feature that would have inevitably made the truck more complicated to build, however, because it adds moving parts that need to be sealed. Hinges, seals, and latches in turn add weight, and complexity almost always invites high manufacturing costs. As an electric pickup built with newly-developed components, the Hummer already has enough of each. Motorists who need to carry something that's significantly longer than the cargo box aren't entirely out of luck. As Mack pointed out, the rear window drops into the partition, so owners will have the ability to haul surfboards, lumber, or anything else that's relatively long and reasonably thin by simply pushing a switch. Alternatively, the only thing limiting cargo space when the roof comes off is the sky — or, depending on where you live, bridges. Mack didn't reveal when the Midgate was dropped. GMC launched the Hummer project in April 2019, and it previously released early design sketches that show how the truck transitioned from a sketch to a prototype. As of writing, nothing suggests the Midgate will make a comeback in the near future on any member of the General Motors portfolio. It was introduced in 2001 on the first-generation Chevrolet Avalanche, which went on sale in the United States for the 2002 model year. It later spread to Cadillac's luxed-up variant of the truck, the Escalade EXT, and to the short-lived GMC Envoy XUV.

Hummer EV could be part of GM's move into electric trucks and SUVs

WASHINGTON/DETROIT — General Motors plans to build a new family of premium electric pickup trucks and sport-utility vehicles at its Detroit-Hamtramck plant beginning in late 2021, possibly reviving the imposing Hummer brand with some of them, several people familiar with the plans said. The so-called BT1 electric truck/SUV program is the centerpiece of a planned $3 billion investment in the Detroit-Hamtramck plant to make electric trucks and vans, and part of a broader $7.7 billion investment in GM's U.S. plants over the next four years, according to a proposed labor deal between the automaker and the United Auto Workers union. The investments were made public by the UAW on Friday, but no details were provided. The investment would move the automaker into a part of the EV market that is largely untested and where GM has a higher likelihood of turning a profit, analysts said. "It makes perfect sense to hit the high end of the market in order to generate some revenue that might actually turn a profit," Auto Forecast Solutions vice president of global vehicle forecasting Sam Fiorani said. GM is mirroring the approach electric carmaker Tesla took by starting in the high end and then moving down the price ladder, he said. That is important for a company who previously tried to sell the plug-in electric hybrid Chevrolet Volt and all-electric Bolt cars at lower prices and higher volumes, but failed to sell enough to make those efforts profitable, Fiorani said. The UAW's 48,000 GM hourly workers are scheduled to vote next week on the proposed contract that would end a monthlong strike that analysts say has cost the No. 1 U.S. automaker about $2 billion in lost profit. GM's BT1 program includes an electric pickup for the GMC brand and an electric SUV for Cadillac, both due in 2023, the sources said. Before then, GM plans to begin low-volume production in late 2021 of the first BT1 model, a pickup, under a different brand, the source said. A performance variant of the pickup will be added to that brand in 2022, followed by an electric SUV in 2023. One of the sources said the Hummer name is "under consideration," but a decision has not been finalized. The pickup is codenamed "Project O." Bringing back the Hummer name would take advantage of a still strongly recognized brand name, Fiorani said.
