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.

Mil-Spec 006 Hummer H1 born into the darkness

Mil-Spec Automotive is up to build number six of its Hummer H1s, this one a customer commission for someone with the last name "Bane." This marks the halfway point in the Launch Edition series of 12 models that will run through to next year. Per customer request, the template started with Build 002, also a four-door slantback, but deviates in a few functional ways. That starts with the four-door slantback variant, but this one gets a much larger rear window. The Bold Body and Tire Package stretches horizontal footprint by eight inches, the bodywork by seven inches. Fender flares hulk over 20-inch gun-black rims wearing 38-inch Nitto Grappler tires. Build 006 shuns the executive interior package on Build 002, putting its cushiness on the outside with the Air-Ride Package. That installs eight-way adjustable shocks all around and automatic ride height adjustment. Sounds like the buyer could need it, since the newest unit also gets the 12K Package that ups GVWR to 12,000 pounds, with beefier axles, springs and braking. A 6.6-liter Duramax diesel sits beneath the $1,299 functional hood scoop, the oil-burner's output rated at 500 horsepower and 1,000 pound-feet of torque. And no road trip to Sonora or Medellin would be complete without a 12,000-pound Warn winch, lavish front brush guard and heavy duty rear step bumper, aluminum snorkel, 60-inch overhead light bar, and Paracord interior door handles. We'd think a locking front axle would be a given on this kind of rig, but apparently this H1 makes do with an ARB air locker on the rear. The brief for the design was "simple yet dramatic." Job done, we'd say, with Build 006 terrorizing the ground like black thunder. The price gets attention just as well: $295,039. This kind of drama doesn't come cheap.

SEMA 2010: Zero South Biodiesel Electric Hummer shows its guts

Zero South Biodiesel Electric Hummer - Click above for high-res image gallery
Zero South, a company that popped up at SEMA in 2008, is back again with its Biodiesel Electric Hummer. The heavily modified H1 rides on tracks at all four corners - a necessary modification, since this Hummer is designed for an expedition to the South Pole.
The trip is going to be documented by Chris Paine, who's best known for the film Who Killed the Electric Car? It was reported back in 2008 that the vehicle was going to be driven by Buzz Aldrin and Apple co-founder Steve Wozniak. The film is called Drive Around the World and was shot in 3D. Drive Around the World is also the name of an organization that works to inspire an urge to explore while raising money for various charities. The H1 shown above is Zero South's vehicle for participating in these expeditions.
