Car Alarm issues
 

Anybody have thier x5 alarm just randomly go off ?

I noticed on hotter sunny days, my alarm just goes off.

I just got my GM repaired... and it only has happened once since... but any ideas on whats going on ?

battery? how old is it?

Battery is no more the 5-6 years old.

you need new battery. OE batteries last about 4-10 years, as proven by members on this forum, non-OE batteries last 2-5 years, again, as indicated by the members on this forum...

in your case, it would be a good measure to replace the battery, as they usually go without warning (well, electrical gremlins are the warning - like the alarm that you are experiencing) and the car may leave you stranded - you go to a local gas station, pump gas, get back into the car and it is DEAD... happened to many of us... lol... :nanana: myself including!!!

An easy way to tell if your battery is weak is to hook it up to a good battery charger with a "percentage meeter" on the charger... if it reads less them 60% after your truck has been sitting for a few hours, you need a battery!

I put mine on trickle charger every other month for a night!

Random alarm issues are generally associated with the hood sensor. Simply disconnect it and your problems will go away. It's located up near the firewall on the passenger side.

I'll try out the hood sensor.

looks like this was the issue... and this thread helped allot:

^ Is it indeed the hood sensor in your case?

it was the hood sensor... disabled it.. and no problems.
