Alarm

Hey guys
So here's a new one. Got to the office this morning locked my car and up about 10 minutes later the alarm stared going off. Ok, odd, but no big deal. I unlocked and locked it again. Another five minutes or so passed and the alarm turned on again. At this point I called the dealer and they told me to open and close all doors, tailgate and hood. So I did, locked the car and about 30 seconds after the alarm went off yet again. I took the beast for a spin thinking it would reset whatever the issue was, nope alarm still goes off. At this point I can't lock my car.

Do you guys have any thoughts or has anyone experienced this?

Thanks and happy holiday!

on the drivers side shock tower is the hood sensor. Just have a look at it to make sure its not came loose or looks funny.

Thanks for the help Scott! I checked the sensor you mentioned and it was fine. I then noticed that the remote start was not working. When I got in the car, there was an error message on the gauge cluster that said something like "remote start disabled - hood open". I then clean the sensor in the below picture. it was located on the passenger side of the hood latch. I think that did it. The remote start now works and even better, no more alarm!

Happy holidays!
Zach

What did you do to "fiddle" with it? Mine started acting up a few weeks ago, and I lowered the adjustment bolts so the hood sits lower. No alarm issues for a few weeks but it started up again today. It's 5 degrees in the morning and I want to be able to use my remote start!

Could one of you who has done this explain how to "clean the sensor" . I can't see anything to clean and it does not appear loose. I have had a couple of intermittent false alarms in the past week. Jiggling the bonnet does not seem to cause any issues so maybe just fiddling has fixed it, if that is the fault!

So the problem went away on its own 1 or 2 days later.
It originally happened during some heavy snow, ice

I called the service department and will bring my jeep in on monday, besides, I also have a problem with the RPM's getting stuck @ 3K or 4K briefly, before going down to the normal 1 - 2k range...these spikes occur when driving below 30 / 40 mph under automatic mode

The faulty sensor is not on the shock tower. I don't have a picture but if you pop the hood and look right where the hood latches, to the left you will see the sensor. The problem will go away where it's not raining/snowy/icy. Seems to be a moisture issue. I've gone to the dealer and set up an appointment, but apparently the sensor is on a national back order right now, no dealerships near me have it in stock.:mad:

I had the same problem with the alarm. Very annoying. I was able to auto start my car the morning the problem started. I got to work and literally 2 minutes after I parked it started to go off. I work close to jeep so I was able to drop My overland off to the service department. They replaced hood latch and sensor for me no problem. Very annoying problem with this car so far. I've also noticed in drive with Eco mode the car jerks between 1st and second gear especially while driving slow in traffic. They updated software and "transmission" and I still notice it. I hear this is common issue on these 14 jeeps.

Is this problem different then having the alarm randomly go off in the middle of the night? This has happened twice to me now (once at 4 am another at 6 am) I live in an apt complex and i dont really want to wake my neighbors up by my car alarm when this happens. I am dead asleep when it happens and the more recent time it happened it was raining outside. Any ideas?

This thread, as so many on this forum, has been extremely helpful. Unfortunately, the hood latch sensor (which is part of the hood latch assembly) is on nation wide back order. Seems to only be happening on those with remote start. Could be 3 months + before they are in stock.

With that said, I certainly can't wait that long to lock my car. Does anyone know if there is a way to disengage the remote start or any other temporary work arounds?

I was messing with mine yesterday. The wire going to the sensor can be taken off, by pulling the red tab back and taking a small flat head screw driver to the flap (the red tab holds the flap down) and gently prying it up. Once you do this the circuit is OPEN and the remote start will not work. If you take a wire and jumper (CLOSE) the circuit your car will start, regardless of the hood being open or closed. I actually ended up bending my sensor to the point where it is always a closed circuit. So i can not remote start my car with the hood opened or closed.

Hi,

I have experienced this alarm event several times. It seems to happen each time I play the music louder than normal. If I listen to music at normal volume there is never an issue. On my way to work now, never exceed 30 on the volume scale or I know our building security will be calling me to let me know my JGC is alarming. Perhaps, loose wire somewhere? I have cleaned the contacts and tried other recommended solutions to no avail.

Kind Regards,

David

I have an oz spec my 2014 where the alarm seems to be related to it sensing something on the seats. The first time it was a mate I locked in while I went to the shop. The second was some gear on the seat. Most recently it was the dog in his cage on the back seat. The alarm sounded after I had locked it and was far enough away for it to be a nuisance- about 50 to 200 meters. It seems to me that this may be a safety feature. Has anyone experienced this and know how to disable it?

The reasons the alarm is going off is it has Ultrasonic sensors near the rearview mirror.
People or animals in the car will set it off, as will leaving the windows down on a windy day.
If it is a regularly random false alarm, then the bonnet switch seems to be a regular problem.

Mine started acting up a couple of weeks ago.
Tried leaving the hood open alar still went off a few minutes later.

All windows closed no animals in car.
Sprayed insecticide in car to kill any stray moths in there.

Still sounding, out of warranty not sure what to do next.

Try locking with key fob then pressing lock on the key fob three more times. This seems to disable the ultrasonics ( as a minimum - not sure if it disables the whole alarm). The vehicle remains locked and leaving window or sun roof open does not activate the alarm. This works for a my14 oz edition at least, but I do not have remote start. It may be worth a try. Hope it works for you.
