Welcome to the forum.

I'm not Sportage owner but I skim read a few posts here and there, and I have some deja vu with your post.

A search of the forum brings up this ("Sort by" date); a bit to sift and digest there.

Hopefully an owner will be along soon to offer more definitive advice.

 

try spraying fly spray in the car and locking it - i had a similar issue for a week with a different car and a tiny moth was inside the car and staying out of sight during the day and then proceeding to fly around inside the car at night setting off the internal motion sensors all the time !!!

 

Thanks for the reply. Thing is I’ve disabled the advanced intruder alarm with is the internal sensors and tilt sensor. So nothing should be able to set it off inside the car.
I’ve called the lease company and they are going to book it in somewhere to check it over.
