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.

2022 GMC Hummer EV Drivers' Notes: We can't stop talking about Crab Walk

The 2022 GMC Hummer EV Pickup defies reason and sense in most ways. It’s a pickup that weighs over 9,000 pounds, but will do the 0-60 mph sprint in around 3.0 seconds. That sounds like something to be afraid of, but itÂ’s also something you want to experience. ItÂ’s a feat of engineering to make something so heavy move so quickly, but thatÂ’s what the EV revolution has brought upon us. GMC gets the Hummer up and moving as quickly as it does with three electric motors — one in front and two in the rear — that combine for a nutty 1,000 horsepower and 1,200 pound-feet of torque. All of that power is unleashed in Watts To Freedom (WTF) mode. Your seat starts rumbling; the air suspension lowers you to the ground, and an electrifying soundtrack is played over the speakers to match your throttle applications. Launching this supertruck is an event every single time, but due to its extra-high ride height and off-road chops, sending it down your favorite trail is, too. That is, assuming said trail is wide enough to fit the gargantuan Hummer. Those knobby all-terrain tires keep the Hummer from being even mildly entertaining when you explore the truckÂ’s handling Â… but who cares. Our specific tester is an Edition 1 model, which means it comes fully loaded with every option you can imagine. As such, its price is $110,295. For the amount of performance and capability on display here, that number sounds surprisingly right. ItÂ’s also befitting the HummerÂ’s status as a supertruck, wherein you get everything youÂ’d ever want in one go-anywhere do-anything package. Editor-in-Chief Greg Migliore — The Hummer EV is the biggest rock star vehicle IÂ’ve tested in quite some time. Literally. ItÂ’s huge and attracts a ton of deserved attention. The Hummer design is spot-on, especially the grille, lights and flared fenders. It looks the part. For $110,000, it should also have some substance, and this Edition 1 delivers Super Cruise, Watts to Freedom and CrabWalk, not to mention GMCÂ’s MultiPro tailgate and the removable Sky Panel roof. It feels quick, as you would expect something with 1,000 hp to feel, and itÂ’s shockingly maneuverable. I CrabWalked down my street to show off, navigating around things on the diagonal and amusing the neighbors. Just the regular four-wheel-steering function, which functions similar to those offered by various other cars, allows the Hummer to turn easily and confidently.

Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.
