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 built a one-off, track-ready Hummer H1

Mil-Spec is one of the latest companies looking for success with restored and modified versions of iconic vehicles. Rather than Porsche 911s or '60s trucks and SUVs, its canvases are Hummer H1s. The customer vehicles are big, brash off-road machines, but that's not all the company is capable of. We recently learned that the crew over there built a Hummer H1 meant for race track use, and it is amazing. The base vehicle is a four-door convertible pickup truck, and Mil-Spec thoroughly changed the suspension. It has custom coilovers with stiff springs, and the entire suspension geometry has been revised. Overall, it was lowered a stunning seven inches compared with a stock H1. The H1's in-board brakes now feature six-piston brake calipers, and the wheels are wrapped in low-profile Pirelli P-Zero tires. Also impressive is the fact that the truck still has a part-time four-wheel-drive system. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Under the hood is a 6.6-liter Duramax diesel V8 similar to that in the customer models. But this one has been tuned all the way up to 800 horsepower and 1,500 pound-feet of torque. This engine also plays a role in this truck's origins. Apparently the truck was used for final powertrain testing and development. But it was also built to highlight the company's capabilities. If you want one of these, well, you can't have one. At least not yet. We asked a Mil-Spec representative, and he told us that there are no plans for offering track-oriented H1s. That's understandable, since the company is still working through building and selling its initial run of 12 off-road-ready vehicles. He did say the truck has generated a lot of interest, though. So, maybe when the company has time, and if a really wealthy buyer really wanted one, maybe the Mil-Spec could work something out. But at least in the meantime, the company is sticking to tall, chunky-tired H1s. Related Video:

Electric Cadillac Lyriq, Chevy Bolt EUV and more GM electric cars are on the way

GM’s murky and somewhat secretive electric car plan is falling into place, as the company dumped a massive amount of information about whatÂ’s in the pipeline at an event at its Warren, Michigan campus today. New EVs are going to be popping up across the GM brand lineup, with new entries from Chevrolet, Cadillac, GMC and Buick in progress. We also learned some big news about GMÂ’s new Ultium battery tech today, but check out this story for all of those nitty-gritty details. The electric vehicle onslaught will begin with the Cadillac Lyriq, an electric SUV thatÂ’s already been teased out. Naming it the Lyriq is the news today. No explanation for the name was provided, so weÂ’ll have to wait for April to learn more. GM didnÂ’t specifically say if the Lyriq would be launched at the NY Auto Show, but that show (assuming coronavirus doesnÂ’t cancel it) will begin on April 8 this year. Next up in the order of events is the GMC Hummer electric truck that we know will be launching on May 20. This truck will use GMÂ’s modular Ultium battery technology. However, the wait to buy a GMC Hummer will be a long one, as the truck isnÂ’t going to dive into production until fall 2021 at GMÂ’s Detroit-Hamtramck plant. GM revealed that its new modular Ultium batteries can be configured anywhere from a 50 kWh pack to a 200 kWh pack depending on the application. Range is estimated to be about 400 miles on the upper end with the largest battery pack, and GM continues to boast about a 0-60 mph acceleration time of three seconds. Charging estimates for the Ultium battery-equipped Hummer EV were also provided. GM says its truck platform will have 800-volt battery packs and be capable of 350 kW fast-charging. Time estimates werenÂ’t given, but those numbers suggest the truck will be a rapid charger. The Hummer truck on hand, which was the same that previously starred in GMC's Super Bowl spot, showed off removable roof panels that store in the frunk, as well as what appeared to be a version of GMC's Multi-Pro tailgate. It also featured sail panels on the sides, similar to those in front of the bed of the Chevy Avalanche. In addition to the Hummer, expect to see a couple Chevys launching. GM says the refreshed Bolt EV will be launched “in late 2020” with a refreshed interior and what appear to be thicker front seats.
