Over 700 systems of the GMC Hummer EV developed during the 2022 and also 2023 version years will certainly be remembered because of a poorly sealed battery pack that lets water in. The company released a stop-delivery order at the exact same time as the recall, as well as it hasn’t discovered how to deal with the trouble yet.
Designated recall number 22V-771 by the National Highway Traffic Safety Administration (NHTSA), the campaign consists of 735 examples of the Hummer EV as well as 89 units of the BrightDrop Zevo 600 van. These 2 lorries are fixed on contrary ends of the automotive spectrum, but they’re influenced by the very same trouble: “the high-voltage battery pack enclosure in several of these automobiles might not have been effectively secured,” GMC notes, including that “flanges on the battery pack enclosure might not have actually been appropriately topped or electrocoated.”
Water can wreak havoc in a high-voltage battery pack. GMC informed NHTSA that it has located three EVs with this issue: an interior examination automobile that shed power while driving as well as two customer-owned vehicles that would not start. Since writing, the company is not knowledgeable about any type of mishaps, injuries, or fires related to the issue, and GMC approximates that just regarding 1% of the remembered EVs are affected.
GMC began informing dealers of the recall in October 2022, and it plans to start connecting to proprietors on November 28, 2022. A fix hasn’t been found. In the meanwhile, the firm provided a stop-delivery order and also asked suppliers not to attempt their own repairs.
This isn’t the Hummer EV’s initial run-in with water-related troubles. In August 2022, General Motors willingly recalled 424 devices of the Hummer EV and also the Zevo 600 van as a result of a high-voltage connector that can prematurely wear away. The issue additionally allowed water leak right into the battery pack, though it sounds like fixing it was sensibly straight-forward and also involved using sealant to the connector.
