security system alarm goes off for no reason in wife's '13 Hyundai Sonata

[Howland]

There haven't been any EA6B Prowlers or EA18 Growlers flying over have there?

I've witnessed it myself in my business park back in 2005. EA6B took off from Greensboro and flew right over my office and set off every car alarm out there. One of the funniest things I've ever seen.

That's almost as funny as being in church one Sunday morning and somebody's car alarm went off outside in the parking lot.

It was hilarious when half the congregation - thinking it might be their car - reached for their key fob and hit the alarm button to shut it down.

But to address the original problem of brother @fieldgrade, WTF does a Hyundai need a security system for anyway?

damifIknow. I just drove up to the gas station with the horn fuse in my pocket.

Push it out the back of a C-130 over NK and be done with it.

As a humanitarian gesture, pack it full of ammonium nitrate to help fertilize their crops. Make sure it has a full tank of fuel, too. It's a diesel, right?

Oh, and tied a lit road flare to the antenna so they can make sure it lands in the right place.

I do like the way you think!

Back in the day, when I ran a ham radio with a big ole linear amplifier (Texas Star 667, for those who care. It dead keyed at 800 Watts and modulated to a 1,000 on full power), I used to have glorious fun setting off people's car alarms.

And opening/shutting garage doors.

And turning touch lamps on and off.

And bleeding over people's stereos. (Totally awesome for the jackasses in cars with the volume/bass turned up so high my own car would vibrate.)

And bleeding over people's phones.

And burning the fingers of anybody touching my antenna when I keyed up the mic.

And lighting up a fluorescent light tube held in the hand next to the antenna. (It would stay lit, too, when you walked across the street with it.)

And terrorizing the local high school teenage wannabe rednecks on their CBs after they had the gall to threaten me over the radio. (Turns out I could buy enough power to totally own the airwaves any time they wanted to use their CBs.)

So you might wanna keep an eye out for some *sshole in a car with a big ole stainless steel whip antenna...

Well I WAS planning to put one of my students in it, and buy my MIL's 2014 Escape with 3,000 miles for the missus. My MIL quit driving two months after I helped her buy it three years ago, but I'm not trusting this Korean car, and their local service dept? ...sheesh. 3 weeks to make an appointment??

Just remember this statement. "
Honda cars would do this. Ford Explorers also. Door switches would be the culprit.
Spray brake cleaner in the latch assembly. Drown/flood it. Do all the door."

The Fords do it also.

The Hyundai's and Kia's are better cars than the Fords. You would be better off sticking with one of them.

The Hyundai has a potential short block issue per letters I've received from them, but has shown zero symptoms thus far. Hyundai apparently doesn't know what to do about it, so they just extended the warranty on the short block from 100 to 120K miles.

Between that, three-week lead-times for dealer service from a dealer I've had really bizarre dealings with, and this crazy alarm issue, it had me a little spooked last night. But I flooded the latches with brake cleaner yesterday afternoon, and adjusted the switch under the hood while waiting on the $20 replacement hood switch. No repeat performances since yesterday around 4PM. I'll keep an eye on it in the driveway and wait a few days before putting the horn fuse and relay back in.

@Mike Overlay's fix may in fact be the solution (big hat tip) and I escape with no more than some aggravation. That said I really hate owning two vehicles under warranty that you can't get warranty service for in any reasonable amount of time.

I think I know now why there's a three week log jam at the local Hyundai dealer service deartment.

Just received a recall notice for the engine short block to have it inspected and/or replaced on 2011- 2014 Sonatas, and there is a metric crap load of them on the road.

Fortunately, I'm not experiencing any of the symptoms they describe, so I'll wait it out.

That is, unless engine preignition (spark knock) could be masking the knocking of worn connecting rods. The ever-so-faint engine knock disappears when I run higher octane gas, so I will assume I am not plagued with the issue that's causing the recall.

The secret to get it worked on quicker is to just show up in the morning and drop it off, they will work it in most likely it may have to stay overnight but they will get to it.

Funny you mention. After your post I texted the service writer (who appears to be a very squared away Marine) and asked him to let me know if any openings came up in the meantime. He just worked me in today.

And the retired guy juggling the incoming cars this morning in their service drive turned out to be retired Dutch special forces, a pilot, volunteered for Viet Nam when he came to the US, and designed aerospace gizmos the rest of his career. Interesting morning thus far.

The Dutch guy walked into the lobby after I was checked in and said he just wanted to "Thank me." I sheepishly asked what i had done to merit that thanks. He basically said in different words, for not being a jerk like every other person who walked through the door everyday. That's when I learned all that interesting stuff about him. Very gratifying. Just exercising common courtesies.

After spending a year in a call center for Volvo trucks, my attitude toward service people changed drastically. I don't usually have any problem now because I don't yell, scream or cuss at them. I smile and am as pleasant to them as they will let me be. Note that I didn't say anything about letting myself be walked on, but usually that isn't a problem.

Check the schedule of Kim Jung Un's missile testing. It's probably going off every time he fires one off!

So I'm looking all over for the horn(s) to disconnect so I can work on the thing without listening to the freakin' horns, AND I HAVE TO TAKE OF THE FRONT BUMPER TO GET TO THE TWO HORNS.

On a Focus you have to take off half the front to change the headlight bulbs. Anything to try and force you into the dealership.

My 2006 Cadillac DTS required taking off the entire front bumper to change the headlights, so I sold it before it went out of warranty. @Mike Overlay thankfully pointed out that I could remove the horn fuse to disable it while I worked on the Korean beast.
