for my check engine light to come on! :clap: It happened on the way home from work a few minutes ago. Anybody else have the dreaded heart stopping, anxiety producing check engine light yet?

airbag light about 8 times.

Twice in 14,000 miles. 1. "Computer reset. 2. "Computer updates" On both occasions, (same dealer) the service rep. asked if I had the gas cap off recently.

Had it back in December, after just 3 months and about 1500 miles. It was a Brake Switch. No further occurences. I posted it at that time. Fix was quick, however, dealer had techs out with flu so they had to give a me a loaner for a night but no big deal, let me see what a Santa Fe drove like. It panicked me initially, personally checked gas cap since I knew that could be a problem, and we were out shopping when it came on.

I used to be terrified of the check engine light but I have found that anything imminently wrong will cause more tangible bad behavior, like misfires. If you get a CEL but the car pretty much drives like normal it's most likely a minor, or at least non-critical, and intermittent issue. Like a dying sensor that gives the ECU some out-of-spec readings sporadically.

When troubleshooting bigger issues the Jags would give regular codes - I have two code readers - so it's no big deal to just read the codes then reset. In the case of the Azera I'd probably just take it in to the dealer. (Unless of course the trouble code said "tighten your gas cap!" LOL )

PS, no worries campoly. Most likely no big deal unless it started running rough or stalled. It does suck to have to take it to the dealer though... just another errand.

I think I might just drive a mile or so down the road and pull over and call Hyundai roadside assistance and say, "help, I'm afraid to drive with the check engine light on!" and insist that they come get me. :wink2:

UPDATE: 3 hours later....short trip (10 miles) and no check engine light. Hmmmm..... :puzzled:

Darn, I was hoping to see how Hyundai responded to the 24 hour roadside assistance program. By the way, has any one used this service of theirs and if so, how did it work?

Cheer up! :whistling: If your C E L is the same as mine, it will come back.

Common thing here is mine did it at about the same mileage as yours has.

Read: http://www.hyundai.com/showthread.php?t...id=2054#pid2054

Should yours come on again, get yee to the dealer A S A P before the code clears itself.
With ours, I do not know whether or not it had set a code the first
couple of times, but it sure set a code the last time it happened.
I thought it was the end of the World.
The motor was running very roughly as it was misfiring
and it had a really noticeable loss of performance.
This only happened on the last time, and when I shut it off and
restarted it, everything was fine and it was running perfectly.

So if you don't get to a dealer in time and the C E L clears itself,
it means that the computer can no longer see any problems.
But if yours pulls the same stunt that ours did, you will want to go to your dealer
and have them find out what the problem is and order the parts and correct it.

I heard after they fixed mine that there had been some bad O2
sensors and the parts guy said that they were being recalled.
It is just possible that yours got one of the bad sensors as did mine.
I am told there are four or five different O2 sensors
and all are different with different part numbers.

Good luck and please keep us posted.

:amen:

Well, I did learn that after a particularly tough tennis match loss, if you stuff a broken tennis racquet up the exhaust pipe and then drive off, the check engine light will definately come on.

I've used it a couple of times. Not for my Azera, but for my XG300L and it worked well. I was very glad to have it available. A quick call to the 800 number and within 30 minutes I had a tow truck pulling up to me on the road.

The first occassion was for some mechanical problem (I don't remember what it was) and the car was towed to the dealer and the problem was corrected under warranty.

The second occassion was for a flat tire. I couldn't break one of the lug nuts loose to change the tire. The tow truck driver was able to get the lug nut off with his impact gun and he even put the spare tire on the car and I was on my way.

Didn't cost me a dime for either occassion.

LOL! That's a funny visual.

We all learn that lesson at one point or another... (IMG:http://www.mysmiley.net/imgs/smile/rolleye/rolleye0018.gif)

Works fine. You call and they come and get your car. I hope not to be useing it again. Although I don't feel that will be the case.
Yota's rule ! :grin:

UPDATE:

I just got a call from the dealer concerning the CEL. The tech said it was an O2 sensor plugged up with carbon. :puzzled: He said it was a rare occurrence on Hyundai and believes it was just a bad sensor.

snaglepus, you hit the nail on the head bro! good call.

I also asked them to check the bounce and wallow from the suspension and told them that I had had the shocks replaced once already as per the TSB.

Anybody wanna guess what they said about that? :whistling:

And todays date is? 06-07-08. Is that a good omen or what?
Thanks, but it was a no-brainer for me as in "Been there, done that." :beer:
Still it is nice to be right once in a while. Doesn't happen much to this old F**t! :P

There were simply too many conditions that were exactly the same as what had happened to ours.
The only differences being that I couldn't go in to the dealer the first time because
it happened on a Saturday afternnoon and the dealership was closed.
The C E L cleared out the next time I drove it on Sunday and I saw no
reason to go to the trouble of complaining to the dealer at that time.
The second time it came on, same deal.
Ah but the third time, that time it was something else.
Instead of just a steady light being triggered, I got a flashing light,
as in "Help Me, I'm in Deep S**t!" :P
I thought something really bad was happening, the way it shock and vibrated, with
no power and it stayed like that for about 30 or more miles 'til I got to where
I was going and shut it down and then immediately restarted it, and even
though the light remained on but steady now and not flashing as before,
the engine was operating normally with none of the missing
or mis-firing as it had been doing before.
But this time, again late on a Saturday, the C E L did not disappear and this dummy finally figured
that Mr. Computer was trying to tell me something, and I'd better get to the dealer.

My question:
Will you be able to determine which O2 sensor of the five (?) was the bad seed?
Did they replace it or simply try to clean it, and if they did replace it as
they should have, did the parts department have the part in stock?

Build date on your car? Ours is 12-12-06.

Rare occurrence they said?
I don't think so because my parts guy said that there had been a
recall on all the different parts numbers for the Azera sensors.
That being the reason that he had none in stock

My 'baddy' was the easiest of the bunch to get to, that being the one you can see
in the front exhaust manifold when you look straight down behind the radiator.

Now, IF only we could score as well on the "the bounce and wallow from the suspension?"

Ours front shocks were replaced at around 5K miles. While it seemed better for
a sort time, it is now after 6K miles just as bad or worse as it was originally!

Really tickled that I hit a home run on the sensor thing.
It just had to be; Couldn't be anything else I figured.
Now if it was the same sensor . .

:amen:

OK. Here is the dealer's invoice for the CEL service and to check the suspension.

 o2sensor.pdf ( 138.68k ) Number of downloads: 29


OK. I don't know how to make the attachment magically appear so you have to use Adobe Reader to see it I guess. It says they replaced the sensor.

Does any one know what "reset the adaptive values" means. Is it related to this sensor?

Check out the part that says "test drove vehicle finding the vehicle riding normally down smooth and bumpy roads, vehicle riding normally at this time, unable to duplicate customers concern at this time "..........BWAHAHAHAHAHAH!!!!

Sorry Mike,

I do not have the capability to scan and print a copy for you as you have done.

In essence, my workorder says:

MILEAGE IN/OUT: 10540/10545

Cause: SCAN CODE PO133 SLOW RESPONCE

39213ROO SENSOR ASSY-OXYGEN LH (UP) RE 228 WHY

1 39210-3C400 SENSOR ASM

39213RPO SENSOR ASSY-OXYGEN LH ADD SCAN TOOL OPERATION 228 WHY

FC: N69-C15
PART# 39210-3C400

REPLACED BANK 1 SENSOR 1 OXYGEN SENSOR

So comparing the two cars, I gather that although the C E L problems
were caused by bad sensors, they were not from the same sensor.

At least yours was repaired quickly whereas the agency that did mine jerked
me around for several extra days even though they had the part.

They had told me to go ahead and drive it while waiting for the parts to arrive, but when they came in at 7:00 am Thursday, they somehow could not find the time to install it until Monday morning.
The service clown went out of his way to inform me on that Monday morning that
they had not been busy at all on the previous Thursday, Friday or Saturday. :liebe011:

Sometimes I get the feeling that these service writer types get their jollies jerking
the customer around. Then the owner wonders why the bottom line is so poor!

Oh well, at least the parts guy and myself seem to have a better re pore. :whistling:



No, can't help you with that one.

Now you didn't really expect the dealer to admit that
there is a problem with your vehicles ride did you? :innocent:

:amen:
