Hello and welcome to JustAnswer!
I've had this happen on multiple vehicles in the past that had aftermarket remote starts. An aftermarket remote start, whether through a failure in the module, poor design or improper installation, can cause the engine to start on it's own when the battery is reconnected.
If you're not the original owner you may not be aware that there is a remote start on the car, there may be a module still wired in but you hadn't realized it. Are you aware of a remote start on the car?
Customer: replied 1 year ago.
No I do not have a remote start.
Expert:  sprinkles08 replied 1 year ago.
Did you buy the car new?
Customer: replied 1 year ago.
Bought the car from my uncle. He bought it new.
Expert:  sprinkles08 replied 1 year ago.
You've confirmed specifically that he never had anything installed on it? Other than a remote start it would take multiple failures in multiple systems for the engine to both crank and then start. I would recommend removing the knee blocker and searching for a remote start module and wiring.

Where is the knee blocker located
Expert:  sprinkles08 replied 1 year ago.
That's the panel under the steering column in front of the driver's knees.
