Does anyone know how to operate the remote factory start...I noticed my car running sometimes by itself

 

You must have triggered the remote by mistake.... or remote starter is defective.

Had my 2011 RDX for a year now, and no trouble with its remote starter.

I have to say though. I hate how the starter works:
-Doors must be locked
-2 buttons sequence to start the car
-Can't unlock the doors if remote started. If I want to enter the car, I need to unlock the doors with the remote starter, engine then turns off, then I need to restart the car manually to start driving. What a stupid idea.
