It sounds to me like there might be a car or truck exhaust that rumbles just enough to set off the vibration sensor on your alarm

Otherwise somebody might be playing with your SUV OR your alarm is a tad to sensitive.

It appears to go off only Wed-Thurs-Fri-Sat mornings. No vehicle nearby to set it off or any other visible interferring / triggering stimuli. This is a factory installed, not an after market. I reset the computer by disconnecting and reconnecting the positive cable from the battery this weekend. I will wait and see if this solves the problem.

My car alarm had the exact problem; clean or replace the hood ajar sensor located right next to the windshield washer resevoir. I little rubber nub. I never even knew mine was there. I cleaned it and so far so good. You could also just purchase a new one, easy to replace with a 10mm socket. I've replaced a door latch, hatch latch and rear hatch sensor and after almost $800 paid the repair shop, it appears I fixed it myself.

I Will call service shop immediately and ask them to check/replace the hood ajar sensor. This is the second time in the shop for the problem. Very annoying to have the alarm go off in the night!

I was getting a "right rear door ajar" message, even when the door was not ajar. The sensor in the door latch needed to be replaced. Same thing was happening for the left read door. Also had that latch replaced. Total cost: $750. The alarm does not go off any more. We saw no pattern to the problem. Money seems to have fixed it. This is the first major expense we have had on the car that has about 120K miles. We drove it once through Mexico, all around Central American, then back: 14,000 miles in five months. No problems.

I have a 2005 Escape that has been doing the same thing around the same times each day. Thought it was the sprinklers at first, but now it happens 3-4 times a day. Did you ever figure out the problem?
