Pressed the button on the electronic liftgate to have it raise. Half way through raising, it beeped 3 times and started closing. Had 3 dogs in the back of the vehicle and the lift gate started to close on one of them. I put my left arm underneath to stop it from closing where the lift gate put a lot of pressure on my forearm. The lift gate stopped and I was able to push it back up. Injury seems to be minor but will have it checked. Feels like it impacted the nerves going to the thumb and pointing finger. This is not the first time we had lift gate issues and have multiple videos demonstrating the problems at hand. This is the first time it actually caused injury.
