I have taken my vehicle back into the dealership because my car will sometimes unlock itself, I am constantly having to check the doors to make sure they are still locked and most of the time it has unlocked itself. Most of the time I hear it unlocking as I am walking away. It is very disturbing. It also beeps as if another vehicle is going to crash into me and most of the time there aren't any vehicles anywhere near me. The phone charger does not work, i have been having issues with this from the beginning. The steering wheel also says I have to put my hands on the wheel when I have them on the wheel. I have a video of the car going a lot of rpms and it barely moved, a golf cart passed me up. The car also locks up sometimes when I am backing up. I drive my parents to San Antonio for their Dr. appointments and am a little fearful of staying stranded either direction. …
