Hi All,

I was wondering if anyone has run into this before. this is regarding a 2007 santa fe.

Today I noticed my airbag warning light came on and stayed on driving to the store. At the store, I locked the doors with the remote, but when trying to set the alarm (second click of the remote) it would not arm (no lights/horn). About 30 seconds later, the alarm then sounded on its own. Had to hit "unlock" on the remote. 30 sec later, the door locks by itself (as it should) but then again, 30 sec after that, the alarm sounds.

Dont know if the airbag light and alarm issue are related. Sounds like a possible electrical issue but I was wondering if someone here might have more insight. We're bringing it in next week anyways, but if it's something simple that I can look for, it will save my wife a trip and gas.

Thanks!

mleone,

You're not alone in this one. My 2007 Santa Fe Ltd. has the same problems.

The "airbag" light is apparently caused by a bad sensor. That's what the service repair guy told me, anyway. They had to order a part to replace it (never having heard of parts inventory), and since I couldn't make it to the dealer when they requested, they sent the part back to the company!

The alarm sounding is the door sensor not being fully depressed when closed. In other parts of this forum, the problem has been suggested to be the "hood" sensor, which is not fully engaged by a small rubber shoe. It is intermittent, and usually occurs (on mine) when the temperature rises or falls (in the heat of the afternoon, or the cool of the early morning).

Like you, I think the electronics really need work! I will take the vehicle in for it's first oil change soon (a month from now), and will see if they can fix these problems.

Now for a question of my own: Is there any way to "disable" the car alarm until I can take it to the dealer? I thought that by yanking a fuse (labeled "alarm system") I could at least prevent the alarm from sounding at 2:00 am, but this is not the case. The fuse prevents the vehicle from being started, but does nothing to the alarm!
Except for just leaving it unlocked at night, I don't know if there is any fix.

Thanks!

Thanks for the reply. Mine appears to be the exact same problem as this post from last year. It's gotta be some kind of relay or something if both the airbag system AND the alarm system are acting screwy at the same time:

My dealership (which will not be my dealership for my next Hyundai) is notorious for "could not reproduce." At least this one is blatantly reproducable...hopefully they don't invent some way to blame it on me.

Just an update.....dealer said the two problems were not related. The airbag warning light was due to an old issue with truck's firmware. They updated to the latest. The alarm issue was as you said, due to the hood latch. Weird that they both happened at the same time. Unfortunately, the dealer doesn't have the part in stock, so we'll have to go back for the fix in a few days. Hopefully that does it. Thanks again for the info.

Hope you get the airbag problem worked out. I've been to the dealer three times already and still the light is on (although it did go out for a while after the third visit).

Not sure if they fixed your alarm problem, but I think I solved mine yesterday.
On the 2007 model, I believe the hood has two sensors, one on either side. Its a small switch surrounded by a rubber ring. When the hood is closed, it supposedly depresses the switch enough to give a "closed" signal. But it's a poor design, as it is no more than "flush" even at the best. So I decided to give it a small addition to help.

I found two small, rubber tabs (from the bottom of an external hard drive stand) and glued them with some contact cement to the top of the switches. They were a perfect match! Now when the hood closes, it depresses the switches a bit further. So far, so good for me. :) I'll let you know if this home remedy continues to work.

I have also had this problem on my 2007 Santa Fe Limited (the airbag indicator and the alarm sounding for no reason at the same time). They both started happening at the same time.

I have the Airbag indicator illuminated in the lower right hand corner of the dashboard control panel. I took it to the dealership on this past Monday (23 June 2008) and they were able to see the error code. But could not determine what the actual problem is. So they cleared the error code, changed the oil, and washed it. The dealership told me to come back if it happens again.

The funny thing about this problem is that it comes and goes. As I was driving to the dealership, the indicator went off. But once I got to the dealership and they went to check it, it came back on and stayed on.

Well, it happened again the very next day. I called the dealership and they have instructed me to bring it in because this should not be happening. They have offered to put me in a loaner car while they investigate what is going on with my truck.

Oh I forgot to tell you what happened after they cleared the code. After they cleared the code on the 23rd, the alarm does not sound when you press the control button twice. They disarmed something on the other day. I’m thinking that they should do a whole system reset or something.

I will keep you posted on what they find during my visit this evening or whenever my truck is returned to me.

Here’s the trick to the sounding alarm problem that I figured out.
1. Arm the alarm.
2. Wait for the 30 sec’s for it to sound.
3. Disarm the alarm.
4. Arm the alarm.
5. All is well at this point with the alarm.

I have found this to work for me. But it is a pain if you ask me. However, until there is a fix for it, this is a solution that works.

Am I wrong here or is only one press of the key fob required to both lock the doors and arm the alarm? I thought the second press of the fob, which beeps the horn, is only to confirm that the doors are locked and alarm is armed. I didn't think the second press was *required* to arm the alarm, as per the opening message in this thread.

That was my understanding. Except I thought that the horn sounding with the second press is primarily a feature to help you locate your car in a crowded parking lot.

Easy enough to verify, but I'm too lazy to go check my manual :whistling:

************* UPDATE ************************* UPDATE ************

I went to pick up my 2007 Santa Fe on yesterday from the shop. These were the findings that might help you get your fixed:

1. Horn problem - They had to make an adjustment under the hood for the alarm. It appeared that the switch was not being fully engaged.

2. Driver side Air Bag Indicator - They were getting a Diag Code of B1332 (Short to Battery @ Underhood junction block connector). This was based off of TSB 07-90-003 (tech notes that they all have available to them).

They ended up using the following Factor Parts to fix this:

FP#
84670-0W162-WK Cover Assy-Consol
91950-2B620 Junction S/O

I hope that this will help you help them resolve the issues with your SUV as well.

Believe it or not, they gave me a loaner car for the whole time they had my truck which was from June 30 - July 7 (the shop was closed on the 4th and 5th). My perspective of the shop has changed for the better since they took the time to listen to me this time and address all my concerns.

Well, several months later and the alarm problem has returned. My wife was at a friends house and for no reason, the alarm went off. She brought it home, we tested it. Same deal as before. You try to lock the doors with the first "click" on the remote....the doors lock but no light flash. You hit the button the second time, nothing. A short time later the alarm sounds on its own. So we're back to not being able to lock the doors.

There is a little switch under the hood latch, which was the problem last time. I tested it this time, it works fine. I can't locate the little rubber things on either side of the hood that people are talking about. I'm wondering if that's what it is this time. Can someone give me an idea of whereabouts they are if you get the chance?

Also, is there any way at all to just disable the alarm (via fuse or relay) so we can lock the doors without worrying about the thing going off?

Thanks!

Mike

Just got the same problem yesterday - on wednsday I went to dealership to change oil, so obviosly they opened the hood cover. Next day I came to work and tied to lock the car and alarm started to sound after 30 minutes. Also on the way home I saw that Airbag light came on and stayed on. here is how i solved it (for now) - while the car is running and Airbag light on , I opened the hood cover and closed it tightly and forcefully - the Airbag light went off immidiately and the car locks fine now. It is now obvious to me that those 2 problems (alarm and Airbag light) are related. Also while doing it I mentioned that the hood cover when closed is not sitting tight, I can shake it and it makes clicking metal to metal sound , like it is not closed tight, but it wouldn't close any tighter doesn't mater what I do. Am I alone? anybody else saw this problem?
