Hyundai Azera Electrical Questions

I've owned my 2006 Azera Limited for two months, but it's mostly been at the dealership for a mysterious electrical problem. If the car sits for more than 5-6 days, the battery is as dead as can be. The dealership found no problems and finally replaced the battery. After 8 days of non-use, everything's dead again. The Hyundai mechanics are at a total loss as everything tests okay. They are asking corporate for an "expert" to help out. I don't even have over 200 miles on this car. Does anyone have any ideas? I've suggested a faulty alternator diode or computer, but testing shows everything positively in acceptable condition. Do I have a lemon? Any suggestions?

  • I would get a different car from the dealer or they would keep this one until it was fixed. Since they already haven't a clue, I think I'd go for a different car and start over.

    Demanding a different car will raise a stink and maybe get them on it for a fix.

    We've had no problems with our 2006 Azera w/8000 miles so far.

  • I agree with the above post. You are also a PRIME candidate for the Lemon Law. If this situation continues for very much longer, especially with the extremely low mileage, I think you'll be getting a brand new car real soon ;)

    RE 3
    The Lemon Law varies from state to state.
    I believe that most statutes require you to have had 3 documented services for the same problem without success.
    That problem should be easily corrected by a tech who has average electrical skills.
    If there is a power draw when the ignition is off, other than the small amount necessary to power security system and clock/computer memory it can be detected with a simple multi meter.

    My vote goes with the diode pack in the alternator. I blew a couple diodes in my Toyota truck's alternator jump starting it. Since not all of them smoked, the "BAT" light didn't light up with the engine running, but the battery slowly lost its charge with routine driving. Once I installed a rebuilt alternator, the battery came back up and held a good charge thereafter. If you want a second opinion (free!) drive your 200 mile car over to an Autozone store and ask them to do a load test on your alternator. They do NOT have to remove the alternator from your car - they merely start the engine and hook up a hand-held instrument to the alternator's connections. You'll know very quickly whether your OEM alternator is putting out the proper charge current at idle speed and above.

    (I'd be tempted to take a bet that during pre-delivery someone at the dealership jumped the battery for a hotshot without pulling the battery's negative lead first.)

    If your Hyundai dealer hooked the car into their computer, all of that information would be immediately displayed.
    If they haven't, you might consider going to another Hyundai dealer for warranty service.

    Sounds like a 'light' is on, trunk, glovebox or similar when the doors are closed. Good tech should find with multimeter. Put in garage at night, lights off in garage, open and close every thing looking for something that is turned on.
    My sons car had a short in the power window switch when he activated the window. Not enough to blow the fuse but enough to drain the battery over several days. This short was in miliamps or lower, everything tested normal.

    The tech needs to check the car for a positive ground vs. a negative ground, one strand on stranded wire could be the culpret.

    Good luck
  • This is going to sound stupid. My brother has an "03 VW Jetta, with the same problem. Might be worth a shot. He was told that when he exits the car, if he sets the alarm, all curcuits shut down except the alarm, and the battery has enough capacity to last for weeks and still start. If he does NOT set the alarm, all curcuits stay ACTIVE and the battery will only last about 3-4 days. Since then he has been setting the alarm, and NO MORE PROBLEMS. Nothing else was done to the car. Since the Azera is a NEW model, the Tecks are learning on us. Its called OJT, On the job training. Feel like a Guinney Pig. Join the club. I have an "06 Azera with 11000 miles, but it goes everyday. Post your fix when they find it, for rest of us.
  • Update: The field services "expert" from Chicago was to have arrived today to check the car out. In the meantime, the dealership replaced the battery (for the third time) and also replaced the radio/6-CD player. Apparently, there's been at least one other instance where they feel the radio/CD player was at fault. The original radio seemed to work okay when I had the rare opportunity to try it. The car started fine over the Thanksgiving holiday, but it hadn't been sitting for the several days it takes to generate the problem. I'm waiting for the call from the dealer.
    As far as their troubleshooting is concerned, they feel that since the problem is electrical, the computer wouldn't be operational to have recorded any codes. But, they checked it anyway, and nothing showed. No lights are on (trunk etc.) but I did notice once that the dome light came on and then went off for no apparent reason. Also, once when driving, the rear sunshade raised into position all by itself. The techs are aware of these things. Countless multimeter checks show no questionable current drainage, other than minimal draw from the clock, theft deterent system etc. For some reason ,they've eliminated the alternator diodes from the possibilities.
    More information later as it becomes available.
  • I would agree with your vote, Ray. I will add that my ex-mother in law bought a new Pontiac Sunfire and the battery died the second day she had it. She had to leave it on a parking lot. We were able to jump start it and it would start but then die almost immediately. I began checking the wiring and found a "plug" hanging loose. I tried pluggin it into the alternator and the problem was solved. Too often dealers don't look for the simpler things.
  • I think it's pretty obvious. Your car is infested with gremlins. ;)

    Yep - little devils get into everything. I'm always shoo-in' 'em away!
  • While checking the engine compartment (with the hood open, of course), it was observed that a small rubber "bumper" was missing from its mounting hole. With the hood open, look near the inside edge of the hood on the passenger's side. About 1/3 of the way from the front edge there's (supposed) to be this bumper knob. When the hood is closed, this knob presses down on a switch (which shares a mounting screw with the coolant recovery tank) that has to do with the theft deterrent system. This knob was missing on my car. The service manager said this is what was causing the draining of the battery. He remarked that on ocassion when people wash or service their car, this knob gets knocked off and therefore draws on the battery. If the car is driven frequently, the battery is kept charged and there's no problem. However, in my case, since my car is garaged for 5-7 days at a time, this is enough to drain the battery. He keeps several of these knobs on hand at the dealership. He doesn't know why mine was missing. Maybe it wasn't even installed during manufacture. So, I'll see if this is really the solution here. In the meantime, everyone might just want to take a look at your Azera (or any Hyundai model) just to make sure it's there. If this is really the fix, it couldn't be simpler (or cheaper)! I'll post another update next week.

    RE: 13
    I'm surprised that the anti theft system would arm without that bumper. Wouldn't the computer "think " that the hood was open?
  • Can I assume that this switch triggers an under the hood light so you can see the engine at night?

    If so, that does make sense and I never would have thought to even look there :confuse:

    Looking forward to hearing that this did, indeed, correct your problem. Had a similar problem with a Ford (I know it's a FORD and you don't have to say it) 1999 Windstar. After multiple trips to the dealership about every 4-5 months with no fix in sight...I just got rid of it.
  • The service manager was correct in that installation of the small rubber knob solved my problem. The car sat in my garage for 15 straight days before I successfully started it! I feel so relieved! Any way, I don't totally understand how this theft deterrent system works, but without this rubber knob, the system never really was armed. After arming (with the key fob), the red light on the upper dash should remain a solid red color for about 25-30 seconds, at which point it will then begin blinking. If anyone rips open any door, trunk lid, or hood, the system will go into alarm (lights flash, horn blows etc.) Before this knob was installed, the light just blinked continuously, the car was really "unarmed" and the battery was slowly being drained. There is no under hood light in this model, and apparently the switches for the doors and trunk are part of some internal devices installed for these things (maybe trunk lamp, door locks etc.). Anyway, I now feel safe in pronouncing my car "A-Okay".

    RE: 16
    Thanks for the info. I have same problem with my Chrysler Seebring. I will now look to see if there is a similar switch, athough my anti theft works fine.

    I went to my dealer to get the limp home code for my 07 Unlimited and the service department told me that the immobilizer systems were not yet active on the 07 Azeras, even though it is discussed extensively in the owners handbook. Any one else found anything out about he immobilizer system, limp home codes, etc??

    Hello, I had mine set on my 06, the dealer was a little confused at first, then set it. If I can remember the code, and all, maybe it will be a help in the future. CMB.

    Anyone need a Factory '06 Electrical Troubleshooting Manual?

    Yes!
    How does one obtain one?
