Over 700 units of the GMC Hummer EV developed throughout the 2022 and 2023 version years will certainly be remembered because of a poorly sealed battery pack that lets water in. The company provided a stop-delivery order at the same time as the recall, and also it hasn’t located how to fix the issue yet.
Appointed recall number 22V-771 by the National Highway Traffic Safety Administration (NHTSA), the campaign includes 735 instances of the Hummer EV and 89 units of the BrightDrop Zevo 600 van. These two vehicles are fixed on opposite ends of the automotive range, yet they’re influenced by the very same problem: “the high-voltage battery pack unit in several of these lorries might not have actually been correctly sealed,” GMC notes, including that “flanges on the battery pack enclosure may not have actually been correctly primed or electrocoated.”
Water can wreak havoc in a high-voltage battery pack. GMC told NHTSA that it has actually located 3 EVs with this trouble: an interior examination vehicle that shed power while driving and 2 customer-owned automobiles that would not begin. Since writing, the company is not knowledgeable about any accidents, injuries, or fires associated with the concern, as well as GMC estimates that just concerning 1% of the remembered EVs are impacted.
GMC started notifying dealerships of the recall in October 2022, and also it plans to begin connecting to owners on November 28, 2022. A fix hasn’t been found. In the meantime, the firm provided a stop-delivery order and also asked dealerships not to attempt their very own repair work.
This isn’t the Hummer EV’s first encounter with water-related problems. In August 2022, General Motors voluntarily recalled 424 systems of the Hummer EV as well as the Zevo 600 van because of a high-voltage connector that can prematurely rust. The issue additionally allowed water leak into the battery pack, though it seems like fixing it was sensibly straight-forward and also involved using sealant to the adapter.
