Every once in a while my g37s alarm would randomly go off. no im not touching the key and pressing the panic button. the car would be sitting in the drive way and randomly start beeping with the lights and everything. it would happen like 2 times a week. ive noticed it usually happens when its raining. why is it doing this? any solutions?

That didnt solve anything?

 

Jeez man, you sure seem to have a lot of odd little problems with this car.

Is there any chance this was a flood car in its prior life before you purchased it?

 

tell me about it. it has a lemon title but the last 30k miles everything was perfect with no problems

 

You tell me .... you are asking a question. I only suggested the link to try the battery on the remote.

 

Does it happen when it rains? That happened to me turns out that water was getting on the bcm

 

what did you do to fix it

 

bump..any ideas

 

Short of it being some kind of a glitch in the security system or the BCM, I remembered something like this from another car.

I once had a BMW 7 series that (among other idiosyncrasies) would randomly set off its own alarm for no reason whenever the battery voltage would get a little low (and I mean just a little). The car's electrical system was inherently parasitic in the off state, so if it didn't get driven enough to keep the battery topped up, it would set off the alarm.

Anyone know? it happens even without rain

 

Dealer .....

 

I noticed it happens when it's locked. Any ideas?

 

When I went to the dealer with the same issue he mentioned that it could be the door plungers sending an open signal to the bcm, apparently it happens sometimes. Either that or the shock sensor could be loose or set too sensitive. If those don't work its probably your bcm. You could try resetting it by disconnecting the battery cable and see if that works. Good luck!

 

Hi guys, i kind of wanted to make my own thread but im not too sure how forums work and i fear i wont get a reply or something like that. I recently bought a 08 G37s 5At (couldnt find a manual) from a private party. To make a long story short heres what happened.
I was with a couple of friends hanging out and they asked me if i could play music from my car. i did and turned the car on every 20 mins or so because i was worried my battery would drain. So on the way home my cars electronics just completely turned off, almost as if the car was turned off (it was still running) so I got it home and parked, i didnt it turn it back on fearing my parents would think i was leaving.So like 20 mins later the cars alarm went off and woke everyone up, i got up and unlocked and locked thinking it was a fluke but then it went off again like 5 minutes later, i then got the idea to drive it around the block to see if i could trick it or something and it worked. So days passed by and nothing much happened until today when the same exact thing happened as i was driving, all electronics stopped, i then pulled over and turned it completely off and then on again. nothing happened and i actually locked it when i got home and it didnt go off. Until i went to the store which is about a mile away and then when i got back home it kept going on and on. I would unlock it and lock it and it would go off again. It now even goes off again even with the car is unlocked. I did a computer reset with the steps in some other forum and this didnt help. Ive done the silent alarm thing where you push both the lock and unlock button and it doesnt work either. The alarm just goes on and on and its getting me frustrated. I dont want it to keep going off and on at night because i sure know my neighbors will call the cops. If you guys could help me i would appreciate it. I love my car and i dont want to have to sell it or anything like that. Any help would be nice

Ps. My dads friend whos an aftermarket alarm installer said it was probably my keyfob or however thats spelled and an electrician that fixed my AC fan said it was probably that.
