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.

Army's first surplus Humvee auction brings in $744,000

The first public auction of surplus US Army Humvees has came and went, and to call it a rousing success would be a major understatement. Auctioneers IronPlanet Inc., unloaded 25 trucks on behalf of the Department of Defense's Defense Logistics Agency. Bidding started at a meager $10,000 for the privilege of driving home in America's most iconic military vehicle. With $744,000 changing hands, the average Humvee crossed the block for just under $30,000, while the highest winning bid was $41,000, for a 1994 vintage, and the lowest winning price was $21,500, Military.com reports. If those prices seem a smidge low, it's because they are. A quick check of AutoTrader revealed that, nationwide, the cheapest Hummer H1 was up for grabs for $31,300, while the most expensive, a 2006 H1 Alpha, was going for $149,995. Of course, there's a good reason you might want to consider the civilian model, as Military.com explains it. AM General, the Humvee's manufacturer, is pretty unequivocal on its website, saying, "The Humvee was designed for a military mission and was not designed to meet civilian safety standards." It gets worse, though. "AM General does not endorse nor support the sale of these military vehicles to the general public or private entities. AM General further opposes any use of these military vehicles by individuals or entities outside of the military context for which the vehicles are designed. AM General does not sell the military vehicle or service parts for the military vehicle to the general public." Somehow, though, we doubt that will stop those that are truly interested in the brutish military vehicle. The 25 Humvees sold in this first auction had simply been gathering dust at Utah's Hill Air Force Base, according to Military.com. Considering this auction's success, and the fact that there are apparently 4,000 more surplus Humvees sitting about, we doubt this will be the last time the military turns to auction houses to unload inventory.

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.
