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.

2024 GMC Hummer EV SUV Edition 1 back on the market after charity auction

The charity auctions at this year's Barrett-Jackson event in Arizona pulled in the usual millions for good causes. Nevertheless, there were no shocking result among the sales like the 2023 Chevrolet Corvette VIN 001 that hammered for $3.7 million in 2022 or the 2022 GMC Hummer EV pickup VIN 001 that hammered for $2.5 million in 2021. In fact, the best result for hammer prices this year was a GMC Hummer EV SUV VIN001 that brought in $500,000, quite a ways down on its bedded sibling. Seems the purchaser decided a little bit of battery-electric arbitrage might be the play, because the SUV is going back up for sale. As caught by CarBuzz, a new member to the Hummer Chat forum started a thread, "Barrett Jackson VIN #1 SUV available." According to the poster who calls himself Bill, "Tread Lightly, the charity organization that the funds went to, aligns well with our company and we were excited to participate with them, however, the Hummer should go to a true enthusiast or collector." The post says Barrett-Jackson "is interested in" putting the Hummer in front of audiences at the Palm Beach auction event April 13-15 or at the Vegas event June 22-24. The vehicle's apparently been built and will be titled in Arizona. It's a loaded Edition 1 in Moonshot Green Matte with a Lunar Shadow interior and three motors making roughly 830 horsepower. There are transparent sky panels that open to create the open-air "Infinity Roof," 14-speaker Bose audio, Super Cruise, Crab Walk and Watts to Freedom mode. Naturally, the seller is willing to part with this bit of history before April and at first said he is ready to "consider a reasonable offer for the vehicle." We're not sure if that means more than $500,000. If so, and without the charity component — the reason these vehicles bring in so much money so often — we suspect such an asking price would be a tough draw. A look at Cars & Bids results for GMC Hummer EV pickups in Edition 1 trim shows prices that regularly surpassed $200,000 last summer are now down to around $160,000. However, two posts later, Bill says his company is "open to all offers."  The Hummer EV SUV Edition 1 retail version will reach begin reaching owners by the end of Q1 this year, which isn't far away. It cost $105,595 when it could be reserved.

Mil-Spec 003 First Drive Review | The ultimate Hummer H1

We're in something of a golden age for automotive restomodding, and into a heady mix that includes Singer's reimagined 911s, Icon's fancy off-roaders, and lots of updated Land Rovers. The latest company with ambitions to become a top-tier custom car brand is Mil-Spec, which aims to do what the aforementioned companies do, but with the big, brash, blunt Hummer H1. And in particular, the company is aiming to make its Hummers a compelling alternative to a used Hummer H1 Alpha. The Alpha is generally considered to be the best of the breed with the most powerful diesel engine offered, larger brakes, and a nicer interior compared with its predecessors. To find out whether the company's early efforts live up to that ambition, Mil-Spec invited us to drive their third completed vehicle, Mil-Spec 003. It started life as a 1995 Hummer H1, and as with all of Mil-Spec's vehicles, it was completely disassembled, and the body and frame media-blasted down to metal. The frame and related components are then powder-coated with a black gloss finish. The truck's aluminum body, in this case a four-door hardtop pickup variant, but is coated in a resilient bedliner-like material designed for easy care. Bits of Kevlar are mixed in with the material for strength, and it can be tinted different colors and have rougher or finer textures. Underneath the body, one of the five different engines that were available on the H1, usually a diesel V8, is replaced with a 6.6-liter Duramax LBZ turbodiesel V8. This engine was available on heavy duty Chevy and GMC pickup trucks, and a related engine was used in the Hummer H1 Alpha. Whereas the engine in the H1 Alpha made 300 horsepower and 520 pound-feet of torque mated to a 5-speed automatic, the Mil-Spec's LBZ has had turbo upgrades and a different ECU tune allowing it to produce 500 horsepower and 1,000 pound-feet of torque. It's also coupled to an Allison 1000 6-speed automatic transmission. The mechanical upgrades don't stop with the engine and transmission. The inboard brakes are given drilled and vented discs, and an ARB Air Locker locking rear differential fitted. Dual auxiliary transmission coolers also make an appearance and can be switched on as needed. The 003 received 20-inch wheels with 38-inch mud terrain tires, but larger tires can be added if desired.
