I recently had to take my 2024 Hummer EV 3X to the shop due to a 'High Voltage Alert Issue.' After holding onto it for two days, they informed me that the entire battery needed to be replaced. It only had 724 miles on it when I brought it in, so it's pretty disappointing to deal with this issue while I was still enjoying my new truck.

Now, it's still in the shop waiting for other parts needed for the new battery, and I’ve been told that it might be ready by Tuesday (which will make it 12 days). It’s really frustrating not being able to drive it around since I absolutely love driving it!

Has anyone else experienced something like this?

Don't mean to be a downer, but I'm in my 6th week of waiting for a new battery and get it replaced. I'd only had my 2x for two months. The battery is in (or so I've been told) and they are installing it (I guess). Probably going to take the rest of the week before I get it back. Let's hope we both get our Hummers back soon and that's the last of our problems! Good luck!

Has the battery been on order for 6 weeks or did it take 6 weeks for them to bother to diagnose it and get a requisition for one? They'd been getting them to dealers in 72 hours (GM doesn't want lemons or buybacks but it feels like dealers couldn't care less if you do) but only if the dealer is proactive in getting it diagnosed and ordering a $45k part. It took almost constant hounding to get the dealer that swapped mine to just get started on it. It's supposed to take a day max to swap (dealers that have done it before can get it done in a few hours) but it took 2 weeks from getting mine in to just get started, then it took 3 full days to do the swap, then 4 days of chasing issues caused by a low 12v and 2 days to find out their charge's breaker wasn't on.

FWIW, even with the dealer dragging it out and seemingly only working on it when they had some free time, mine to 28 days from error to new battery and it's been trouble free ever since. It increasingly feels like this is a QC issue with cells. The vast majority of cells are fine but every once in a while a bad one makes it into a pack. The thing is they planned for this. Dealers were supposed to be able to drop a pack, open it up, replace the offending module, seal it back up, and get you back on the road...but that program was never implemented (and they've had 3 years to get it in place) but instead they're just replacing whole packs as they need. So now you have them shipping 3300lb packs to dealers everywhere instead of 80lb modules. I have no doubt its a logistical nightmare.

Sorry for not responding sooner, but the battery was on order for 6 weeks and it took them another 2 weeks to put it in... Uhg... No problems with the battery since I got it back. But now it's been back at the dealers for 3 weeks to fix a problem where it won't lower from from normal to entry/exit. They ordered a compressor control module and are waiting for the company that makes them to come through. No eta... Ugh again... If the hummer wasn't such a bad ass truck, I'd definitively go lemon. I'll see how long it takes to get it back and how pissed I am before I decide which way to go.
