Elantra HD (2006-10) :: 2007 - Alarm Tripping Randomly
Apr 27, 2011
So my factory car alarm has started going off by itself ; had to unhook horn wiring.
Bad hood switch issues are talked about ; seemed a little flaky when checked with meter so I changed it out, only $15. Hood pad already was made higher as a first try at fixing problem.
Still having alarm tripping sometimes. I read somewhere about the door lock actuators having a contact that tells alarm system when they are locked.
So I may have a faulty power lock assembly on one of the four doors. I have tried to open them when locked but they don't open. How to I tell which lock switch is bad , they are all pricy but the drivers rear is cheaper.

Recently I took my car in for an oil change, & after that when I lock my car it doesn't always make the beep noise to let me know the alarm system is armed.
A little while after that, my alarm started to go off randomly. This happens at random times, all my doors are closed and we even took the car in to get checked(they checked the wires or something I believe because they thought it had to do with my aftermarket remote start)
I've read somewhere about people saying it could have to do with my hood switches? But truth be told I'm not very good with cars.

We moved to a new home two months ago.My 2009 elantra alarm randomly goes off only between 9:30pm and 8:30 am and only when in my garage or driveway. Dealer "adjusted hood sensor" and it still activates. Seems the issue must be in my garage as didn't happen prior to moving and happens no where else. I disconnected the garage remote wireless sensor tonight to see if that could be culprit.

The alarm on my 07 Elantra is going off and I tried disconnecting the battery to no avail. What can I do to stop it from going off an keeping me from driving the car?

Recently my keyless remote was wiped with wet paper towel to get rid of some detergent the fell on it. Since then the alarm has been tripping for no good reason. The only way the alarm stops is when i open the car with my key and put the remote in the keyless remote holder.

I got my oil changed and tires balanced Saturday at the local shop around the corner. Now my alarm goes off randomly and when I use the clicker thing to lock the car, the horn doesn't make the beep sound it used to on the the second click. It never did this prior to having the oil changed, but how could that have anything to do with the alarm? I need to figure out how to make it stop, it's waking me (and my neighbors) up at night, and I have to keep leaving where ever I am to go out and see if the dang thing is going off again, which it is about half the time.

2012 Hyundai Elantra. My alarm goes off randomly. About 3-4 times a day. Is there an easy way to shut off the sound so it will never go off? Naturally, I don't want to lose any functionality of the remote/smart key or the push button start. Just to eliminate the beeps.

2014 Elantra SE with premium package, I've had it a little over a month. Last week the ac plug stopped working in the passenger seat area. BF said have them check at first service.
Now the trunk wouldn't open with my key fob, or the spare. So I thought maybe a shopping bag handle got in the way. On the way home from the store, the trunk open light popped on randomly. Trunk wasn't open. Okay, that's odd...
Now the alarm has been going off randomly. 3 times in the past 2 hours, I'm wondering if it's a massive electrical problem waiting to happen.

I have a 2013 Elantra GLS. Several times in the middle of the night the alarm that sounds when the door is locked just starts chirping randomly. Why that is?

So far three times this week the factory alarm went off in the middle of the night. This happened before and the problem just went away. I have pulled the fuse for the horn so I can at least get some sleep.
How to troubleshoot this? Bringing it to the deal will be useless since I can't duplicate the problem.
This is an 08 Santa Fe limited edition.

Over the past few days, my (factory) car alarm has started going off in the middle of the night, with no one/nothing near it to cause it to go off. The car battery is less than 9 months old, the doors, windows, hood and trunk are all always closed. Why it is happening?

First time here with my 2008 Elantra. (Bought new - Now 140,000 miles) Just started having a problem. Car alarm going off by itself?? Would a low battery in the remote cause that? Where would I go to find info?

I have a 2010 Sanata with 69500 miles. I have been getting a P0456 code for some time. I have replaced the gas cap, purge valve and the close vent valve and filter. The code still wont fully erase and keeps tripping the MIL. I have done a smoke test and there are no visible signs of leaking anywhere. What this could be.
One question I have in live data the purge valve never seems to go below 2.7 percent even when the engine is off. it was like that be for and after replacing it.
Could this all be caused by a bad ECU? I was told that in a 2010 Sanata that the ECU is common to fail. When the MIL is on I have 3 of the same code one freeze frame one that triggers the light and one that says permanent. Every time I erase the codes all but the permanent go away. No matter how many times I hit erase or even disconnect the battery it will not go away but the light shuts off.

I have had my 2010 Elantra for about 2 months now, and 'all of a sudden' the car alarm starts going off - lights, beeps, at random. I have read a few places it has to do with a 'hood switch' - so where do I find it and what do I do with it once I find it?
Dealership has not been too friendly so far (not surprising - it IS a dealership), if I can find a quick and easy (and cheap) fix I can handle myself, I would rather do that. I prefer NOT to disable the alarm as I do want it to work.

I have a 2008 Hyundai Elantra. When it's windy out the alarm keeps going off. Especially if the vehicle has been locked with the remote. If I manually open the vehicle and lock it manually the alarm is fine. I have had it to the dealer and they say the system is fine and that the sensors are fine.

So the situation is my battery died on my car and whenever I go to jump it the alarm goes off as soon as the cables connect. I let it sit for a minute and the alarm goes off for a period then turns off, then it starts going off again then turns off repeating this. The car wont turn over and I can't figure out how to turn off the alarm. How to get it to jump/turn off the alarm while it charges? I wont take it to the dealer to get it fixed unless its 100% something I can't do at home.

I have a 2008 Elantra SE. The anti theft alarm gets triggered for no reason on occasion. At first I thought it was only on rainy days, but now it happens in full sun as well.
I don't need the alarm, as nobody pays attention to them anyway. Is there a fuse I can remove to disable it?

I have a 2009 Elantra with a hair over 107 000 km. Recently I have been having an issue whee the EPS (Electronic Power Steering) has been randomly turn off while driving. This has occurred anywhere from once a week two twice in 10 min. It has happened immediately after starting the car or after driving for half an hour. There is no visible or audible sign when the EPS shuts off other than a small warning light on the instrument panel.
I am very worried about the safety risk this poses to me and the vehicles around me as when the EPS turns off the car is very difficult to steer, so I would like to get this fixed ASAP. What I should be looking at? Is this something I can fix myself (I'm not very car savy) or should I be taking it to a mechanic/dealership?

I have a 2010 Elantra where the rear driver door randomly won't shut. The lock intermittently won't engage and the door just swings back at you. Happened twice and I just thought nothing of it and played around until it closed. I was at my dealership (for another problem) and I opened that door to get something out of the backseat and the door just swung back at me when I shut it. They kept the car and lubed it up and said it was working fine. 2 weeks later it happened again when I was running errands and it took me half an hour to get it to close again.
This particular thing apparently isn't covered under warranty so my solution was don't open the door. Now my trunk is doing it too! The trunk has always sporadically opened on its own every now and then and I always thought maybe I was pushing the button on the transmitter... Nope! My car went back to the dealership for the trunk and the door. They got my trunk to close by "fiddling around" and couldn't recreate the door not closing and both APPEARED to be working fine. The next day the trunk wouldn't close again. I got it to close by playing around with the lock and the transmitter. It opened again while I was driving.
