Why is my car un-possesing itself?

Here’s the problem: I have set up a car based on the sedan, but with my own mesh and tweaks. I added some blueprint code so that I can possess the car with the first person player by pressing E, and teleporting right next to it when at 0 speed and E pressed again. I have a world with three levels set in world composition.

When I enter the car, I start by driving away from level 1 and into level 3. When I am at the furthest point, I drive back. That’s when at a very specific point of the level, which is not when entering back in level 1 (actually quite far from it), my first person player respawns at the starting position with me in it, and the car keeps driving itself until it finds a wall (I can see it in the distance).

What could be happening?

This is a good question but your statement really doesn’t make much sense to me.

I am encountering something similar: in a 10kmx10km world composition map and I am using the “Driveable Sedan” marketplace asset - when I drive far enough from the origin (at amount 455270 cm) the vehicle got automatically deleted.

That was a long time ago, but I remember what happened. Turns out my island was broken into three levels. Whenever I exited one of the levels and entered the other, the car (which actually was the pawn) did that thing. But when changing levels, the controlled pawn reset somehow. I don’t remember how I solved it, but that was the problem. Sounds like it could be your problem too.
