Recently, I have had 3 instances where my car alarm suddenly goes off. All times, my car was parked in my garage, unlocked. The keys were sitting on the table and had not been touched.
The only thing is that I think the battery in my remote is started to get low I think but I don't really see how that would cause this issue.

View 2 RepliesSo my battery is dead dead.... Looking to charge it, but of course, the alarm goes off. How do I turn it off?
View 2 RepliesI have a 2006 sonata and my alarm light on my dash board is blinking rapidly and then my blinker lights will turn on and stay on for a few seconds then it does everything all over again. My car has never done any of this except a slow blink in the red LED alarm light. I don't want my battery to die! Is there anything wrong with my car or is this normal?
View 1 RepliesI have a 2007 Hyundia Sonata. Currently have a 7" after-market head unit, four after-market speakers and a sub that is currently not plugged in. I also put HIDs in the low beams. It has about 73,000 miles on it. I bought it when it had 36,000 about a year and a half ago.
The first time I noticed an issue was about 3-4 months ago. Both of my stock headlights went out at the same time. I checked all fuses, nothing blown. Odd right? I thought there might be something going on with the electric but I was like O.K. i guess i'll get new ones, i could use some brighter ones anyways. So I went with Sylvia SilverstarUltra's. These lasted 2-3 months before one went out. I didn't think at the time that this was connected to the previous problem because only one went out and I drive a LOT with my headlights on during the day and SilverStarUltras have a short life span. So I bought an HID kit off ebay (just the ballast and bulb, not really a 'kit'). I installed them on Jan 28th. Today, Feb. 25, they both went out. NOT COOL!
Electronics : Sometimes as I am driving the electronics in the car "de-surge" if you will. Another words, they seem as though they have less power, the interior lights dim, the fan for the heats slows. This happens only for a second and then returns to normal. It has happened a few time. I don't remember the stereo being effected however.
Sub : The sub on my speaker system. A couple of months or so ago I noticed that my sub on my speaker system had stopped working. It was installed late last summer. I investigated and found no potential short, the ground was secure, and no fuses were blown. I didn't even think this could be related to everything else until today, but it kinda seems like it might be.
I was wondering if maybe I had created a short of some type when installing the stereo system. However nothing in the stereo system seems to be effect besides the sub. Which gets it's power directly from the battery, not the stereo system.
I read on another thread about a older Elantra that had this problem and someone mentioned that it could be the regulator in the alternator going bad and intermittently outputting too much voltage. Although I don't know why that would make the fan and lights in the car slow/dim. I'm currently trying to find someone who can lend me a voltmeter.
How I could locate an electrical problem with my stereo install, or elsewhere in my car?
My Alarm seems to be having an issue recently. When I hit the remote the doors lock but the lights do not flash and the beep is gone. When I hit the remote to unlock, the lights flash. Last Night I opened all the doors hood/trunk and shut everything and the lights flashed and it beeped. Since I have no door indicator lights I was wondering if there is a sensor where it thinks the hood is open possibly? I am at 57k so I am still under warranty. I had a Blazer years back when the alarm started acting up, they had to replace the computer one time and I think the battery the second time. But I don't think it is that. I did have some work done recently to put a blower motor and Brake light switch in. I did see reference in another thread from 2 years ago about the alarm for a different model car. 2009 Sonata 3.3 ....

Was driving along today, with music and bass quite loud and the front driver door speaker just simply turned off. All other speakers work fine, including the tweeter on the driver side.
Before I take apart the door panel to check for connections (my main suspect), I'd like to have your opinions on this issue. I already broke the tweeter panel when taking it off to replace my broken side mirror, I'd rather skip taking this off again, with the door panel, if I don't have to. But I assume it will be inevitable to get started!
My 2009 Hyundai Sonata's dashboard readings suddenly went "dead" yesterday that is - the fuel gauge read empty, the speedo wasn't registering nor was the tachometer and the led display couldn't be altered? What might be wrong and whether I can do anything to fix it?
View 3 RepliesToday my transmission suddenly disengaged while slowing down from 3rd to 2nd as if i switched to neutral.Car revved freely when i pressed accelerator. Then suddenly after a second it engaged again and shifted normally. Never had this issue before i racked up 1,29,000 KM on my ride.
I can't see it as "slipping" as there was no change in speed and it revved freely. Also I 'm due for fluid change. What can be the issue?
So i have a 2005 Sonata GLS and it has been giving me issues. A week or so ago, the 'check engine' came on so I took it to the shop to have it fix. Problem fix, no more light popping up. Now two days ago, the car all of a sudden started stalling and hesitating while I was driving. I kept pressing the gas and the car will accelerate to 40 before slowing down to 20 and the acceleration will then drop as well. I had a mechanic look at the issue and he said it was the throttle position sensor. He changed the sensor and its still acting up. He said to buy the carburetor cleaner and it worked fine for a hour until we drove it again. The problem is still not fix.
View 3 RepliesMy problem is on wed I was driving my car,when I suddenly lost acceleration power, after pulling over to the side of the road I turned off the car and restarted it. However I still had the same problem with acceleration. After a while of trying to get the car to start I called a tow truck and got it towed to the dealer. When I got there they told me it was likely and issue with with a sensor on the gas pedal and the engine. At the dealership I started the car to show them the problem however the car drove perfectly and no engine light came on.
They told me it was most like what they said over the phone the sensors. However on xmas eve they called me and left a voicemail saying the rear cat had went out and taken out both rear exhaust manifolds and it would coast $3000 to fix. My question is how can all that happen without the checking engine light coming on in the car and the car showing no problems while i was driving it and how did they miss it when I had took the car in two weeks earlier for regular maintenance and to correct a drive belt issue due to it walking after I purchased a new drive belt and pulley.
I just pick up a 2000 VW Passat and the next day the alarm started going off. Non-stop honking, doors locking, etc. Pulled back the carpet near module box and there was a ton of water. Water in the box. Board in the box needs replaced and I would like to look for it online vs buying thru the dealership. Also, I'm trying to find out the part # or exact name of the part so I can look it up. I hate dealing with the dealership so I'm trying to find out what I can online before spending half my day on the phone being transferred and put on hold over and over.
View 4 RepliesEvery 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?
Alright so I got my car detailed today, including the engine bay. Since I got it back I've noticed when locking the car it doesn't make that locking beep. But it does when unlocking the car.
Also noticed when locking the car, all doors lock, no lights, and that little alarm red light doesn't stay lit for 30 seconds when first locking the car it just flashes normally. So, no sound, no lights. What's the problem.
I have a 2013 Sonata GLS and I need to reset the alarm system, as well as the door chime system.

View 6 RepliesMy wife is driving my 2012 GLS today. I have the keys with the remote with me. Shes at a friends house and only has the key, no remote.
She just called me and said the car wont start and when she opened the door using the key the alarm is going off. She said she can't turn the key all the way forward to start the car
My plan is to go by her friends house on my way home from work and use the key with the remote. However WTF with this situation???
I just did a quick google search and found how to get the alarm to stop going off by leaving the key in the ignition for 30 seconds while its turned ON.
I am having issues with 2015 sonata sport. My car alarm has been going off randomly as well as lights flashing/beeping as if I was pushing lock button on key fob. I am not pushing any buttons and sometimes it will happen when The key fob is in my hand and I know I'm not pressing any buttons. When it does happen the little red light will flash on the key fob. I've tried using other key fob and have same issues with both. Also I have had to change the battery in both key fobs about 8 times thus far and I've only had the car a little over a year.
It does not happen all the time and I know if I take it in, my luck the car wont do it and they will tell me they don't see anything wrong. Sometimes the buttons wont work to unlock/lock the car and after a few minutes the car will beep and lights flash on their own and I will be able to then lock/unlock car again. This is getting very frustrating and it has become an annoyance for me and I'm sure my neighbors as well. I even will have people I work with come in and tell me my alarm is going off during my work shift.
For my '13 GLS, I leave my fob in the center dash box compartment, and lock the doors using the button on the door. Sometimes when I unlock the door w/my key, the alarm goes off. Why is that, and how can I prevent that w/out having to carry around my fob?
View 2 RepliesI've had my 2011 Hyundai Sonata Limited for one full year now and this is the first problem I've encountered, and its a strange one.
After parking and shutting off the vehicle (with the push button since I have the smart fob) if I exit the vehicle and shut the door the car will produce a loud BEEP for several seconds. If I look through the window, the screen on the instrument cluster will very briefly say "key not in vehicle" as if I had left the engine running, but actually the engine is off. The message goes away after a second or two, but the beep continues for a few more seconds.
After the beep stops, I'm able to lock the doors normally by pushing the button on the door handle or using the remote. It seems to happen about every other time I park/get out of the car, but it is random. The only pattern I've found is it always happens if I am in a rush. If I turn off the car, open and close the door quickly, it almost always beeps at me. But if I turn off the car, sit inside for a few extra seconds and THEN get out, it seems to be fine. What could be causing this?
Had the 2011 Sonata 2.0T for two months. Was running perfectly. The today engine light stayed on. Disconnected battery then started again. Still on. Guy said check gas cap. Added gas AND disconnected battery again. Light stayed off on way home. Then started it again and it is on again. No overheating. Oil is ok. etc. everything else works just fine.
