GMC Hummer EV Is The Subject Of A Voluntary Recall

GM has voluntarily recalled the GMC Hummer EV, over battery concerns.

The GMC Hummer EV hasn’t been on sale too long, but it’s already the subject of a recall, from GM. The recall is voluntary, meaning, the NHTSA hasn’t forced GM to issue the recall, but rather, GM is just asking owners to bring their vehicles in for a fix.

GM says that water can potentially get inside a high-voltage connector, causing premature corrosion. GM didn’t say what the corrosion could do, but obviously, excess water inside of a high-voltage battery isn’t a great idea. If there is a battery fault, the vehicle will inform the driver via a trouble code light. The recall affects the 424 GMC Hummer EVs, but also GM Brightdrop Zevo 600 commercial vans. GM didn’t say how many of each vehicle is affected.

The fix is ready and simple. A technician will remove the high-voltage battery connector, apply more RTV (room temperature vulcanizing) sealant to the plug, then reapply.

Yet again, the NHTSA isn’t involved in this recall. But, this is not the first time the GMC Hummer EV has been affected by a recall, voluntary or not. In March, the NHTSA made GM recall GMC Hummer EVs over a software issue that could cause the taillights to stop working. The GMC Hummer EV is the first iteration of the Ultium platform, hopefully, GM can get the bugs worked out before the Cadillac Lyriq, Chevrolet Blazer EV, and Chevrolet Silverado EV start showing up en masse.
