Do You Think This Is My Problem ??? >>>> failed diode
My 04 XG 350 L With 22000 Miles On It Has A New Battery 2 In 2 Years ,, It Keeps Going Dead.

I Took Out The Add on Alarm , Thought That Was It But It Was Not It, Today The Batty Was Dead Again, So I Charged It Back Up To 100% And took A Drew Test With A Test Light, The Light Was Lit With Nothing On, I Then Started Pulling Fuses ,, And Fuse # 21 Under The Hood Was Called Power Fuse And The Test Light Went Out, I Started The Car With Out The Fuse And It Set 2 Codes
This Was The Codes P1118 Manifold Absolute Temperature Circuit Low Input,, P1178 ( open )

So I Plugged In My Tester And Cleared The Codes That I Set In There.

I Also Replaced That Fan Belt But That Was After The Battery Was Going Dead, So Its Not The Belt I Know Its Tight Also I Went With The Toque Specks
Any Help On This Problem ??

I Did Buy The Extended 10 year 100 Thousand Mile Warranty 0 Deductable

Thanks For Any Help

You do not check parasitic draw with a test light, invalid test...

Use DVOM with mA function, and get a real number value as to what the parasitic draw current actually is... then you start pulling fuses till the draw drops like a rock... typically anything above 25 is suspect when car is sleeping.... so be sure to either disconnect hood switch, or hold hood switch down --> I have mile long leads on my DVOM, so I just close hood after I get set up and running.

You will perform Draw test with doors closed, and keys out of vehicle

Yes I Do Know About The DVOM But Its Over My Friends House, Like I said the Test Light went out when pulled fuse 21 the power fuse.

I'LL recheck in the morning or at noon, when I get my DVOM back

Or Take it to the dealer, i only have 22000 miles on it and its an 04 with 10 years 100,00 mile warranty , I did buy the extended Warranty on it.

Thank You For Your Answer

10/100 not cover electrical concerns... thats 5/60, and you is out of warranty there.

Yea, customer pay work, pays better than warranty. :banana:

Found my 2013 Elantra had a very dead battery, checked the voltage and it was 1.9 Volts. Tried a battery charger, but it would not take a charge. Called Hyundai Road Service. The service man had a lot of trouble getting the Elantra to start, but after 20 minutes, we were able to start it. Took it to the Dealer, they fully charged the battery, and performed a load test, which indicated it was a bad battery. They replaced it under the warranty as it was less than 24 months old.

I'm new to this foru so I don't really know if I need to start a new thread as nobody seemed to answer the question. I have a 2004 XG350 and the same thing. Battery dead in 4 days. Third new battery before I figured something was wrong (duuu!!!)

Used ammeter to find .05amp draw on pwr 1 (30 amp fuse) but worse a .17 amp draw on the big square 40amp fuse marked for power windows that actually controls the seats and steering column and who knows what else.

I have seen loads of people with xg350 with the same problem (battery dead in 4 days, no charging or battery fault present).

Did Hyundai ever let slip what the design fault is that causes the problem so that I can fix it?
