Toyota Etios Cross

I bought a Toyota Etios Cross in 2019. It is a lovely car, there's just a few glitches with the car. Few days after I bought the car I noticed the boot sensor was problematic. It was closing but showing on the dashboard that it is not closed. Took it to Eastvaal Toyota dealership in Potchefstroom and it got sorted. Now recently my alarm system started acting funny, it would go off suddenly without any triggers even in the middle of the night. I then took it again to Eastvaal Toyota dealership in Potchefstroom and they picked up that the sensitivity of the motion sensor was set too high. I was told that there's a few cars of the same model that were brought back with the same problems. The car is lovely but if the manufacturer can look into these small malfunctions it would be great because it is really frustrating to wake up in the middle of the night because of a noisy car alarm. Thank you Eastvall Toyota in Potchefstroom for all the assistance with my car problems, much appreciated.
