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.

Could the GMC Jimmy come back as a Wrangler fighter?

Every three or four years, two cars go into heavy media rotation in stories about supposed new competitors. The headlines go something like, "X automaker working on a vehicle to fight the iconic Y." The Y cars are the Porsche 911 and the Jeep Wrangler. For this story, the X automaker is GM. And since GM already has its 911-fighter poised for debut next month, we speak here of the Wrangler. Car and Driver writes that GMC might take another shot at a Jeep challenger, this time by rebirthing a body-on-frame Jimmy SUV. For any who don't know, GMC sold an S-15 Jimmy from 1982 to 2005, a twin of the Chevrolet S-10 Blazer. Those SUVs started their lives as the Chevrolet S-10 and GMC S-15/Sonoma pickups. The Blazer name has returned to the light, albeit without its old-school rugged manners. There's still an opening on the GMC side, though, so C/D says the idea would be to work that old magic on the GMC Canyon pickup. The report is more chaff than grist for the rumormill, with liberal application of phrases like "looking to come up with," "could be," "could take," and "could arrive." Having said that, a potential Jimmy model could come in a few years, could use the same six-cylinder gas and four-cylinder diesel engines as the Canyon, and could start around $30,000. The Jimmy could wear GMC's new mud-and-guts AT4 trim name, or become a mud-and-guts trim for the Canyon just as the ZR2 is for the Colorado. It's not an entirely crazy idea, however, when a body-on-frame Trailblazer SUV based on the Colorado sells in Latin America, Asia, and Australia and does pretty well in the mud and muck. GM's been on the edge of going to war with the Wrangler for at least 12 years, when a Hummer exec said the HX concept would debut at the 2008 Detroit Auto Show and go on sale in 2010 as the H4. In 2015, The Wall Street Journal said GM was canvassing GMC dealers about something to get in the ring with the Wrangler. And all that was before every other automaker had to watch Jeep open a money-counting operation to handle its Wrangler profits, and dealers started charging $20,000 markups on Gladiators. In May, spy shooters caught a sensor-laden Jeep running at GM's Milford Proving Grounds in Michigan. Earlier this month, Bloomberg reported GM is considering a Hummer revival as an all-electric hardcore SUV. So we will not be surprised if GM rolls out a Wrangler fighter in the near-ish future. But we won't be surprised if GM doesn't, either.

GM announces 6 recalls covering nearly 720k cars

General Motors has announced yet another sprawling recall campaign, with six separate elements covering 717,950 vehicles on US roads. At this point in 2014, it's starting to seem like there are more days with a GM recall than without. Perhaps most troubling about this latest volley, though, is that every vehicle is from the past few years, indicating that GM's quality woes may not be limited to pre-bankruptcy vehicles.
The largest element of this latest campaign covers 414,333 units, and includes the 2011 to 2012 Chevrolet Camaro, 2010 to 2012 Chevy Equinox, GMC Terrain and Cadillac SRX and the 2011 to 2012 Buick Regal and LaCrosse. Only vehicles with powered, height-adjustable seats are covered. In these particular cars and crossovers, the bolt that secures the height adjuster actuator may loosen of its own accord and in some cases fall out completely. If this happens, the seats will be able to move both up and down. GM claims the vehicles are safe to drive, provided drivers don't vertically adjust their seats. This particular issue has caused one crash and three injuries.
