Sonata I45 (LF 2015+) :: Car Alarm Going Off Randomly As Well As Lights Flashing / Beeping
Oct 2, 2016
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.

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 ....

This morning, while getting ready for work, my car's alarm sounded. I ran outside in the rain, and it was beeping and flashing, but there was no one around. I unlocked the doors, looked inside, everything looked fine. Shut her up, reset the alarm. Not 2 minutes pass and it goes off again. Same drill. This time I start the car and the MFA indicates the rear compartment is open, I check and it's not. I open it, shut it, and reset the alarm. You know what happens next, the alarm goes off.

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?

No Beeping sound for passenger seat belt, just flashing sign on the dashboard. Just want to see if this is normal or not? ( I would assume it should not be).
If so, I could go to the dealer and get it fixed. This is for 2013 Sonata GLS.

Where to find the fuse for the alarm flashing lights? It should be inside the dash, but I didn't find it.

A friend of mine is having issues with her 03 Tacoma. Last night her alarm went off so she went down to check it out. Turned the alarm off and re-activated the alarm. About 20 seconds later the alarm went off again. She said she unlocked it, climbed in and started the truck. The warning lights (check engine etc.) are now flashing even with the truck off and no alarm activated.
My best guess is water, at least a little moisture (it rained last night), somehow got into the ECU or some other component of the alarm. Or possible corrosion on a wire or connection. Does that sound like the right direction to go with trouble shooting this issue? I downloaded a manual for the alarm.. I am assuming it's an RS3000.

Recently a strange problem has started occurring with my car's radio (I've had the car for about 3 weeks). I usually listen to SiriusXM. When I start the car, it'll stay on SiriusXM for about 5 seconds or so and then sometimes it will randomly switch to either AM or FM radio on its own and I have to manually switch it back. I don't think it's a loss of signal issue as the radio will play SiriusXM just fine before it jumps to another band.

On my limited sometimes when I am driving randomly and a car is in front of me but not far up my collision warning signal goes off.
It's only happened about 4-5 times and I am not sure what sets it off or how it even really works?

As I am driving the steering wheel will randomly lock for about 2 seconds. It has happened while changing lanes on the highway, also happening while making turns in intersections. Took it in to the dealer, all they did was clear the code and give it back to me. I have notified Hyundai Customer Care and they are supposed to contact me but right now the car is unsafe to drive.

The hazard lights (4 ways) have a mind of their own and will randomly flash once and then few minutes later it'll flash again.
I've checked the dash switch, did a quick clean with electrical contact cleaner, that's working fine.

I drive a 2007 Lexus GS 350 with 60,000 miles on it. Today I was running an errand I parked my car and then went back to work. After four hours I came back to the parking lot and heard a really low beeping sound coming from the parking lot. It turned out to be my car. I tried to open the car door with my keyfob and nothing was working. I opened the door manually and was not able to turn the ignition on as there was no internal power. I finally jump started the car and alarm went off as the car started.
I got the battery tested and the battery was completely fine. I called the Lexus dealership and explained the problem and the technician did not think there was anything wrong with the starter or anything else with the engine. The gentleman I spoke to thought you might have been Keyfob battery that may have caused this. One thing that I noticed last couple of Was that the car air filter needs to be changed. Could that have caused this to happen?
Temperature has been in the 90s in the week or so! The car was parked in a covered parking ramp!

New 2015 Mercedes E350 wagon ..... The day after I took delivery, I tried to open the new wagon's doors (it has a keyless feature) and nothing happened. I tried again and still nothing happened. I then took the smartkey out of my pocket and tried to click open the locks and nothing happened. I then took the ancillary key out of the smartkey and unlocked the car manually. This set off the alarm which would only stop when I closed the door and relocked the car.
Also, the car would not start. It was like I had broken in to the car. A few minutes later, while waiting for roadside assistance to speak with me, I tried the door handle again and discovered that the doors would now open keylessly. I have driven the car several times since the incident (which occurred yesterday) and it has not repeated the problem. What caused the problem?Is this a one time glitch or am I in danger of being stranded somewhere?

I 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?

I've noticed lately that I wish the lights on the temperature control display and the clock were a brighter during the day. Especially when the Sun shines on them and they get washed out. I've tried increasing the display brightness, but it doesn't really seem to work. Could I just have a dim display?

Apparently while I car was at the stealership for it's 45k service, the car alarm was going off crazy and wouldn't stop, so their techs disconnected the horns.
First time they delivered my car back, the horns wouldn't work- sent it back.
Second time around, porter turns off car, closes the driver door, and car alarm starts blaring, other techs and customers starting and closing their ears..
Not sure what could be going on.
