NHTSA Complaint #11652897 — 2021 CHEVROLET SILVERADO 2500

The tailgate on our truck keeps automatically coming down and up on its own. It doesn’t matter if the truck is in park or drive. It doesn’t matter if it’s locked or unlocked. It will do it several times in a row. It will go half way back up and then just slam down. Unfortunately we didn’t know this was an issue as we just bought the truck a few days before we noticed it happening and it fell down and hit something in our garage causing a dent and multiple scratches as it happened overnight without us being aware of the issue. It happens when I’m going down the road, which means I cannot use the bed of my truck as things could fall out. Also, I’m limited on where I can park it. We called GM and a dealership and there’s nothing they can do since it’s not recalled unless we pay to have it fixed. So now we have a new to us truck that’s now dented because of this issue. There is no warning it’s going to happen. After the tailgate comes down I get a notification saying tailgate down when I’m driving. This happens everyday, several times a day and we’re having to avoid driving it when possible due to this issue.
