2018 SI Coupe - Car Alarm Keeps Going Off

[Doc_C]

I'm almost certain this is a BCM issue as it controls both the alarm and the locks/door switches. It reminds of the early 2000's Caravan/Town & Country from Diamler. My neighbor had one and in the middle of the night, I would watch the thing lock and unlock itself frequently and open/close the sliders and rear lift gate. Quite entertaining actually. I just loved the look on his face coming out in the morning and seeing his doors open.

Hi SDotLee, I'm new to this forum. I have a 2018 Civic hatchback and facing the same issue as you do. Is it resolved now? What was the response from Honda? Please let me know. Thanks in advance.

Hey! Yes for me it was a bad door lock actuator in the driver side door. That was replaced under warranty and the issue never returned.
