I have a 1999 Honda Civic with a factory alarm system. For some reason the alarm goes off at all hours of the day. After the alarm goes off, I check around the car and there are no signs of forced entry or any type of glass breakage sounds that would cause the car to react. The only thing that might be causing the problem is the variation in temperature or moisture. It seems very intermittent. Any suggestions would help. Thanks.

 

never heard of an alarm going off because of temperature difference, maybe there is a short? bad battery? i know your car is pretty new, but you never know...

good luck!!
