Hyundai - Elantra :: Alarm Keeps Going Off Randomly After Oil Change
Mar 18, 2013
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.

My 2004 Hyundai Elantra GLS has an alarm that won't go off until the car is started and running or the negative battery cable is disconnected. The technician at the Hyundai dealership is baffled on this one. If I press the panic alarm button on the key chain, the alarm gets very loud. When the panic alarm is turned off, the alarm is quieter. The keyless entry won't work at all now.

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.

I have a 2003 Hyundai Elantra with about 96,0000 miles on it. A couple of days the car wouldn't start and I assumed the battery was dead. Also, every time I would turn the key, the alarm would do these short successive beeps. After AAA came to see about replacing the battery, he saw that the alarm would beep when the key was put in and told me the anti-theft system was preventing the car from starting, and that a new battery wouldn't fix it. At the time, the battery in the key fob was also dead but I got that fixed and the key fob is working.

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.

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.

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.

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?

My daughter's 2008 Elantra starts fine and seems to be idling okay. But recently at seemingly random times the car will stall within a few yards after she starts driving from a cold start. She will start the car, start to drive and then all of the dash lights come on and the engine shuts off. So far she has been able to turn the key and immediately restart the car and then it is fine after that. The problem always seems to occur after she has driven somewhere, let the car sit for a couple hours and then tries to drive again. We took to our mechanic and they said there are no diagnostic codes and the fuel pressure seems good. They did identify some kind of voltage drop/issue with the mass airflow sensor and replaced it. But a day later the problem occurred again. Mechanic seems stumped. I'm very worried about my teenage daughter driving a car that randomly stalls.

My 2008 Hyundai Elantra likes to play KeepAway.
The driver's door randomly locks itself when I get out of the car. Just the driver's door. I have learned either to make sure the others are unlocked or to take my keys with me, even if it's just to pump gas.
Might this be some easily replaceable or resettable circuitry, or do I just have to live with it?

I have a 2007 Manual drive Hyundai Elantra with 98,000 miles on it. Prior to going to Valvoline (who I know are not the best oil change places) if I was parked with foot on clutch and brake there was a tinny noise coming from the engine. I was going to have it checked out.
Fast forward I had my oil changed at Valvoline on Saturday (2 days ago) since then when parked with foot on clutch and brake the car begins to make a stuttering/shuttering noise and is shaking a bit (in time). In addition when I shift gears and go faster there is a wheezing noise.
I assume I need to bring this back to Valvoline? Is there anything that they could have done during the oil change that would cause this issue?I didn't get the air filter but it wasn't that horrible. They of course said I should get the radiator flush and the transmission flush.

I have a V10 TDi Phaeton and all of a sudden the alarm is going off randomly. There seems to be no rhyme nor reason as to when its happening.

My dad has a very low mileage '12 Camry XLE with the 4-cylinder motor. Recently, the alarm will just go off randomly. After re-arming it, it may go off again in a few minutes, and may do this many times in a row. Or, weeks may pass where it doesn't happen at all. It is a really annoying issue. The battery is fully charged, and both FOBs had their batteries replaced.
I know if it is brought to the dealer, and the problem cannot be replicated while there, they will tell us that they cannot diagnose it. I have read that it may be the hood latch and sensor.

My car alarm keeps going off randomly. It doesn't matter if I lock it or not. The car alarm just goes off and quits on its own. What might be wrong?

I have the car in storage for the winter, and from time to time i will go out and start it. I also hook up one of those automatic battery tenders every so often to make sure that my battery doesn't die completely. I bought the car about 3 months ago, and when i bought it, i could tell within seconds that the car needed a new battery. I will buy one and install it as soon as i am ready to start driving it again. So thats the background story.
My problem is this.... for some reason, with no regularity, the alarm just starts going off. Sometimes it will go off shortly after i ran the car, sometimes it will go off when the car has been completely undisturbed for days. Im wondering what is causing this. I have read things about the sensors having trouble with moisture, but i don't think that is the problem because it has been inside the garage for over 2 months.

Every time I lock my Sonata, either by the lock button in the car or from the fob, the alarm goes off about 10 minutes later.
Can I just disable the car alarm?

I just recently put a new battery in and I was wondering if thats why my car alarm goes off sometimes? I've also noticed about a week ago in my gauge cluster that the sign for the door being opened was on and then it turned off and then flicker on and off for about 30 sec ? So I think that has to do with the alarm but my question is how do I fix this problem???

I have an issue, and I don't know if it's kids, animals, or the car itself. Last night it happened at 3am, tonight I'm sitting on the couch at 12.30am and it just went off again....
I don't see anyone out there around the car, not sure I saw anything last night either. Is there a cause for this? I just replaced my 12v battery in March, have a dead FOB smart key in a fire box (it's up on top of everything in the box). My current key was lying flat on the bench, nothing on top of it.
