Re spawning van keeps breaking for no reason?

OK so, I made a post about this before. I have a car crash game and for the longest time i've been trying to make the cars able to re spawn (I'll include extra info at the INFO Section at the bottom) So basically the car would always break and I thought it was because of the HitPart, So even disabling the script in the part and cancollide it would still break. However, I think in my honest opinion I was being stupid so I think its because the car needs to be un-anchored to drive, so the scripts inside of the car un-anchor it while it is spawning in, however i still don't know if this is the case, so if you can please help. (Also plz no hate for free models im just trying to make a fun game)

Model: roblox.com/library/187731990/Transporter-Van

INFO: So I made it able to respawn however like I stated above I thought it was because of the HitPart so I disabled the scripts in it and cancollide but it still broke the van. Now i think it's because of un-anchor scripts inside of the van. (I could still be being stupid) I Mostly just want to know what you think is causing the van to break or not. Even now at the time of writing this 5/31/2020 4:00AM EST, I still don't know. However Like i Stated above I Just want to know what you think is breaking the van and if it is code inside the van I will search the code for the part for it and try to disable it or add a system to fit my respawn system.

Anyways thanks if you can help!
