Elantra MD (2010-15) :: 2013 - Factory Alarm Will Start Going Off For No Reason
Nov 18, 2013
Having an interesting issue with my 2013 Elentra Limited ....
A couple times now the factory alarm will start going off by for no reason. This was confirmed by my neighbor, who was sitting outside when it started going off the last time with nobody around it. Also, when this happens, the alarm button the on key fob will not stop the alarm, only unlocking the car will stop it.
Also, after this happens, I can no longer set the alarm (pressing the lock button twice and hearing the car honk once) for usually at least a few hours if not a day. what happens is that i press the lock button and you hear the doors lock but if you keep hitting the lock button, the doors just keep locking, the car never honks.

I've had an intermittent problem with my factory alarm going off for no reason at all. I replaced the Courtesy light switch on the driver's side hoping to stop my problem. Earlier I found the connector was barely on the button switch and after discovering that I thought the problem would stop. I feel like this car is possessed!

I have a 2007 Ford Taurus, the factory car alarm goes off without any apparent reason. It had been a garaged car but has been sitting outside for about the last 10 months. It started doing this in May so I thought it might be heat related due to the high temps we have been experiencing in the midwest??
Sometimes when I get home from work around 5:30pm it will go off within 5 minutes of me getting home. Then other times it will wait until 2 or 3am. I can't lock my doors in my driveway anymore or my neighbors are going to come over and tear the horn completely out.

There is roughly 800 on the odometer and I was averaging around 35 mpg. I filled it up and driving home afterwards I noticed the mpg drop off significantly. Now I'm lucky to get get 27. It was as low as 16 on the trip computer. The range was the same and the miles come off in sync with the odometer. I'm wondering if its a glitch with the trip computer?

Picked up my brand new elantra last week, however alarm was not working properly. It arms ok (i.e., horn chirps after two clicks, lights flash etc)...but when we tried to test the alarm (as part of my delivery inspection), nothing happened. We tried opening door without key, opening from a half open shutter etc.
Dealer promised to resolve issue, they've been good so far, but it's worrying me a bit, brand new car, I shouldn't have to think of these issues and take my car and leave it in the dealer garage for a few days for them to diagnose this.

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?

I recently bought the Santa Fe Sport 2017 model. The alarm just keeps going off for no apparent reason. It seems like any wind or a car driving on a street will set it off. Is there a place where the alarm sensitivity can be adjusted?

I just installed the Hyundai factory Remote Engine Start in my 2011 Elantra GLS and have a problem that the hazard lights come on and stay on when unlocking/unarming the car. To repeat, this is the genuine Hyundai Accessory Remote Start/Security kit (3X056 ADU00), not a third party offering. Everything that the kit is supposed to do, WORKS as specified, including remote start. The only problem is that when I use the key fob to unlock/disarm the system, the emergency flashers/hazard lights come on and stay on until I turn them off from the inside or until I toggle lock/unlock for the key fob a few times.
I've been through the wiring a dozen times, and am absolutely certain that the kit is wired correctly -- again all features work. Now, I find it interesting that NONE of the wiring of the kit (based on the schematic) comes close to touching a circuit that is identified as hazard/flashers! I even temporarily disconnected all four leads from the kit that go to the front headlamp circuits and rear tail lamp circuits -- and the hazards STILL CAME on when unlocking. This is telling me that there is an indirect/unintended "connection" between the kit and the triggering of the hazard circuit.
The kit is clearly the correct one for the car, and the car has the right equipment for the kit (i.e. No Smart Key, has auto transmission, power windows, power locks, etc). Why the hazard lamps come on when I click the keyfob to unlock the car?

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?

My alarm went off for no explainable reason today. My car is parked in front of my house and all of a sudden I hear an alarm going off. Now, I've never heard my own alarm so I wasn't even aware it was mine until it kept going and I realized it might be mine. So I went to look out the window and I couldn't decipher where the sound was coming from because there's a lot of cars around here
So for the heck of it, I grabbed my fob and kept pressing buttons to see if it would go off. I was so flustered and nothing went off so I thought it wasn't mine. Then I held down the red button and it finally went off.
Does it mean someone tried to open my door? What warnings should I look for on the dash when I go in there for the first time after shutting off the alarm?

Can a remote start system be installed on the factory alarm ?

Today I came out of a store & my car started beeping the panic alarm. I don't carry the key fob with me, just a key. I unlocked the door, sat down, put the key in & turned the ignition. The lights all lit on the dashboard as normal but the car did not start. absolutely nothing. I was at a loss for what to do.
Fortunately, someone came out of the store & asked me if I needed a jump & explained what happened, and he said let me try something. He tried to start the car, then got out of it, locked the door, unlocked the door, sat back down & tried again. The car started right up.
The car is a 2014 Elantra SE with the Premium Package.

I have the oem fog lights but I was just wondering if the driver side is slightly higher than the passenger side fog light.
Also what is the knows from the back of the assembly that is counter/clockwise.
What direction does this do? Left to right or up and down. And which way would be to lower the lens if it is up and down.

2013 Elantra with 62k miles. I am dealing with a strange issue where I experience sudden engine shutoff and no-crank no-start situation when I attempt to restart. This typically happens during warmer weather (above 95F / 35C).
When the engine shuts off while i'm driving, the following symptoms occur:
-Temperature gauge (all bars) disappear
-Shift level selection disappears from dash
-stability control light is illuminated
During that state, I'm unable to restart the engine (even when the level is in park or neutral). Anytime the attempt to restart, the following symptoms occur:
-all of the above symptoms when engine shuts off
-TPMS light is flashing
-engine does not crank when attempting to restart.
-Unable to move shift lever from Park when key is in ON position, even when depressing the brake pedal (have to use shift lock release to get it out of park into neutral). Trying to start the car in neutral makes no difference.
The car stays in that strange state anywhere from 5 minutes to several hours. After that, I'm able to start the car and drive it for 10-60 minutes, until above issue repeats.
The issue is NOT any of the following:
-Battery
-Starter
I know that some users have reported a similar issue due to a bad inhibitor switch, but with that issue, only the gear selection disappears from the dash (while the temp gauge and other functions remain normal). Could it possibly be a bad ECU?

2014 Elantra GLS ... Upon closing, and just as it reaches the wind defector, the Sunroof will " kick back" no apparent reason. This may happen once, twice in a row or not at all. I have checked the sunroof path and the wind defector, but no obstructions are visible.

I just recently purchased a 2013 Elantra Coupe, and the Engine Start Stop button will not light up anymore. The small LED above the "Engine Start Stop" lettering still lights up blue or amber if it's in ACC or ON mode, but the lettering itself no longer lights up.
I'm not sure if it's supposed to stay lit while driving, but I noticed it started to flicker at various rates, and then eventually it stayed lit. Now, it's not lighting up at all. I'm wondering if there's a fuse anywhere that could be associated with this or anything I could check myself before taking it to the dealer. I haven't had a single issue getting the car to start with the button, just wondering what could be causing the lettering on it to not light up any longer.

When starting the car and ONLY when it's a cold start, like sitting overnight, it makes this weird "groaning" or "whining" noise. I took a video of it because if I drive it to the dealer, then start the car there, it's not going to do it as it only happens after a long period of being off. Listen really closely after the car starts and right before the radio comes on, you will hear a faint groaning noise. It's louder in person, but this is the best I could do.

I have a 2013 Elantra GLS, with Push Start ignition.
Whenever I get out of my car for a few minutes, I keep the engine running, so what I do is, I keep the Smart Key inside the car, and remove the physical key trying to lock the doors from outside (I do this to keep the car cool from inside because the heat in my country is scorching!)...what I found recently is that as I do this, only the driver door gets locked, and all the other doors are still unlocked...I don't know if this is a fault or standard....

I've got a 04 Passat TDI wagon with factory keyless locks. The remote/keyless entry range sucks! And yes I put a new battery in it. I've had cheapo alarms operate much further than this factory system. Can I extend the range somehow? Does the keyless transmit through the antenna? Are there any range boosters or ways to make this a real world usable feature?

My 08' Camry i4 LE has been locking the same way..... I press the lock button twice, then the car honks once, and everyone's happy.
About a week ago, my car started honking twice after I press the lock button twice. This hasnt happened in 1.5 years but it didnt really bug me.. at first.
My problem is... my car's alarm goes off randomly after I lock it. It's like someone pressing the panic button on my fob.. What is wrong with my car all of a sudden??
I read another thread and have disconnected the battery. I will wait an hour and re-connect to check again. I've also read somewhere that I might need a "latch and sensor replacement"..
