On July 3rd my wife had a dealer appointment for an oil change on her car, so I was loading my 3yo into the car seat in my Model 3 so we could drive my wife back home after dropping off the car, and something felt off as i was tightening the restraints. Luckily I investigated further and found the seat belt was completely loose and I could move the child seat multiple inches off the actual seat. At first i thought maybe some passenger in the back seat had accidentally undone the seat belt, but it was buckled in still. Also due to coronavirus I can't even remember the last time I had an adult back there. I also thought maybe something was wrong with the seat belt locking mechanism, but when i pulled the belt out all the way and tested it, it seemed to be working fine. I also noticed some other odd things: the seat protector i had under it was shifted to a position I would not have left it in, the top strap of the seat protector was also totally loose. Also, I had taken the car out the prior weekend and noticed the extra length of strap from the top tether was hanging down over the child seat, but at the time I had assumed it must have just fallen down, although normally I roll them up and tuck them behind the car set.
After all that I remembered I had taken the car in to get the FSD computer installed on June 23th. Obviously i don't know for certain it was the cause, but it seems the most likely. I don't know why they would have removed the child set in order to install the computer, but maybe this is expected? Has anyone else experienced this? I would have much preferred if they had to remove the child seat to just leave it laying in the back seat unconnected. I must have driven at least once with my daughter in that seat, incorrectly installed. I don't know if I should contact Tesla about this since i'm not 100% certain about the cause, and I already filled out the survey they send (everything else about the service was fantastic).
