So I had to make a run out to the local wal-mart and on the way back my driver's side seatbelt light started coming on mid drive after that ended my battery light came on and immediately after that ABS and ESC Off lights both came on and there was a sudden loss of power in my car. I made my way in to a nearby parking lot and turned off the car for a few seconds and tried to turn it back on but it was acting like the battery had died. Thing is I just replaced the battery no longer than a month ago. After a few minutes of looking around the engine bay and some choice words I got back in the car and it started up without any of the lights on. I started my way back home again and again the same thing happened and I just went ahead and got the car to limp home.

I'm gonna step out on a limb. Have you performed the brake switch recall yet? I seem to remember something about this and they were related somehow. ???

Keep us informed as to what the outcome is please.

Since battery was replaced a few weeks ago, that is where I would start looking. Clean and tighten battery connections.

Ah thing is...when I parked in the parking lot and took a look around...the connections looked brand spanking new and were both snug as a bug in a rug.

-=Edit=-

So I decided to sit in my car and leave it running to see if anything would happen...same thing happened again car threw the 3 lights Battery, ABS, and ESC Off. When I turned on my headlights the radio/cd player completely shut off on me. And the headlights looked really dim. Does the 06 have any electrical problems?

IF you have not already,,,,,,, replace the POSITIVE battery cable assembly.... known problem for last couple year for voltage loss concerns. Part number been changed on it

Test the voltage on the battery with the car off. If it's about 12.5 or more, then your battery is good and you have loose wiring somewhere or a bad computer. If the voltage is less than 12, pull the battery and have it tested - you might have gotten a bad battery, or a wire is loose, or the alternator is bad, etc....

'06 Sonata IS an electrical problem: A/C - SRS - ESC, etc.................................................... reminds me of a buddy's Fiat convertible (X19?) from the late 70s = spent more time in parking lot than on the road

Unfortunately it sounds like you got a bad example if you are having lots of electrical problems. Or maybe your Sonata has been abused or damaged. I have not had any problems, electrical or otherwise, with my 2006 Sonata in 120,000 kms. It has provided bulletproof reliability.

How much are the cables? What is the warranty time frame (5-60 or 10/100?). How hard to change for a very good DIY person? I'm starting to notice some flickering on my interior lights but I know my dealer will just be a PITA and blame my HID's/fogs, radio, etc. I have a new dealer closer to me so might let them attack it if warranty would cover (car is 4 years old and about 76k) only has "standard" warranties no extended bumper to bumper.

This info is for V6 3.3 Sonata and 3.8 Azera---

Last price I had on the cable is approx $139... dealer should idealy have 1 on the shelf... New part number ends in 3K111 I think it is.. If dealer fella any good, he should be able to grab it right off shelf or know exactly what you asking for

Warranty on the cable is 5/60...

DIY.. not hard at all.. worse part is you will need to get under front to swap cable end at starter (part of the replacement part).. end at alternator post, some routing across front of engine, end at fuse box, and battery cable clamp.. at worse maybe 1.5hr at home if you not in hurry.. maybe an hour or less if you determined to be done with it.

All done from top right there, except for the starter post and soleniod connector. Straight forward job, couple wrench and socket is all.

----------------------------------------------------------------------------------------------------------

Appears you have a 2.4, that cable not been a problem for us... I would suggest anyway that you follow the negative cable to the place where it end,,, likely bolted to painted panel (insulation) and the 2 bolts ?? have rusty threads (more insulation)... If the cable end bolts to painted fender, remove cable, and grind the paint off so the lug mates to clean bare metal.. smear the bare metal with anti-seize or other to prevent rust.

While you got the battery loose, there is a strap on left frame rail by battery tray, goes to trans case... grind paint off frame rail mounting point too.. see how that works out.
