Super cruise does not work. It may turn on at random for a minute or 2 and then it shuts off with zero warning and the vehicle almost comes to a complete stop. This is a huge safety concern. I took it to the dealership and they told me that this falls on GM 100% as they are being told GMs engineers are trying to find a fix but for now there is nothing they can do, I am to continue driving it knowing this is unsafe. The turn signals and Bluetooth stopped functioning for no reason which had to be fixed Battery charging module burned up at 300 miles. I asked for a buy back and GM refused. I asked for an engineer to come on site and they refused to set it up unless something else is happening as if this super cruise issue isn’t enough. I filed a complaint with the BBB hoping to get the attention of someone who would actually realize how unsafe this is and that same person from GM lied and said I declined assistance. I asked that lady for help and she stated that it would have to wait until something else happened.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2024 GMC Hummer EV SUV verdict →
