I can also confirm this as it has happened on two separate occasions. On one I found a truck in Myshkino I walked up next to it and my screen just went black and the "You are dead" text came up. I know I wasnt killed by another player because I returned to this location shortly after respawning and the truck was still there plus no gunshots were heard.

The second time this occurred was after a server restart. I was driving a truck when I lost control and ended up hitting a fence and flipping it over. I knew that server restarts flip the trucks back upright so I waited for it. Once the server restarted sure enough the truck was back on all wheels. I approached and open the driver door which cause the truck to spaz out a bit and shake which was shortly led to the "You are dead" screen again without the truck even touching me.

On both of these occasions I was able to return to the trucks and use them as normal. It also seems that there is a bit of a lag/desync issue as a few days ago a friend fooled around a little too much and ended up running me over. However on my screen he was still a few feet a way and I actually managed to move out of the way of the oncoming truck but I still ended up on the "You are dead" screen.
