I have 2012 Buick Verano, keyless engine start.
As usual yeasterday, I turned off engine and when I open my driver side door, I was hearing beep sounds that is continuous and similar to the sound it does when i forgot my keys inside. If i close the door, it stopped and again if i open it continues. It’s kinda continuous beep sound. Afterthat, I also realized that my lights are stay on even after locking my car and that for longer time then I ser and it used to.
