My car parking lights start blinking like i had used my remote. car makes blinker sound occasionally and locks on its own. the blinking happens mostly at night and went on and off all night recently. My check engine light is not on. no other problems.

Hi lkp95,

Thank you for the donation.

Symptoms indicates the security system is being activated and the most common cause would be the door switches.
Check if any of the door switch covers are dislodged or damaged.
Check all doors for proper alignment.

Does the door ajar indcator lights sometimes tun on while driving?

The other possible cause would be a fault with the Body Control Module which would require appropriate diagnostic tools to check.
