09/15/2017 driver door ajar came on showing door was open. Closed door several times and it would go off. This happened several times until 10/10/2017. Now it won't go off and my doors wouldn't auto lock when in motion and wouldn't stay locked manually either. My dome ligh would stay on also. 10/16/2017 car would not start, battery was drained and no lights were left on. Called garage and jump started vehicle and took it in for repairs. Just got call that the battery and door ajar sensor will have to be replaced. It will cost almost $800. 00 to fix. The warranty just expired on vehicle and that leaves me with the bill. I read numerous other complaints about the same vehicle and same problem. There should be a recall on this. It is a big safety issue especially when you have children and the doors won't stay locked.
The driver door and rear driver door "door ajar" notification's do not turn off, even when the doors are closed. This causes the dome lights to stay on which drains the battery, and then the vehicle will not start later. This also prevents the doors from locking while driving. This is an ongoing issue and can not seem to be resolved, even after a mechanic cleaned and lubricated the door latches.
