Alarm going off on some mornings - already replaced hood sensor and IMS

[randywei]

Hi All,

Wondering if anyone else has encountered this issue.

About 2 months ago the alarm for my 2013 X5 would start to go off on random mornings. The car is parked outside and it seemed like the alarm went off around the same time around 8:20AM after the sun hits the car (but the alarm didn't go off every morning).

I had the hood latch sensor replaced, but the alarm still went off. I then noticed that if I disabled the Interior Motion Sensor (IMS) by double locking then the alarm wouldn't go off.

I brought the X5 to my indy and their AutoLogic read out that the alarm log was filled with entries saying the IMS was what triggered it. They replaced the IMS (the entire front ceiling dome in the front of the car), but the alarm STILL went off on a couple mornings. If I double locked to disable the IMS then the alarm wouldn't go off in the mornings.

Brought the car back to the shop and again it read as the IMS triggering the alarm. The shop is trying to get the IMS part warrantied for a new replacement, in case somehow the one they installed is bad.


Any ideas? Anyone else experience a similar issue?
