I won't attempt to diagnose your problems (aside from a few basic comments) but it appears that since the problems started after a near total of the car something done during extensive repairs is the cause. The car should have been totaled, but that is another story. Is any of this weather related? that is, does damp-wet weather seem to be related to your non-start condition? If, as you say, each time this non-start condition surfaces a different code is logged then maybe the engine management computer is somehow involved?. You want to sue? who and why since Hyundai clearly is trying to fix it but cannot pin down a single cause and I'm guessing you do not want to throw more $$ (parts/labor) at it in the hope a fix will be found by accident. In my opinion this is going to be a gremlin you will chase until A. the car wears out B. you get tired of fooling around and sell or trade or junk it. C. some repair facility gets lucky and stumbles on some part change/electrical connector reseat/ pinched or partially cut wire within a harness or some other thing you will be able to trace back to that original repair. Electrical problems are a horror and yours is compounded by the almost total rebuild of the front of the car. The fact the radio has a mind of its own as well just reinforces my thoughts of a harness/electrical connector. Good luck!!

Today on the freeway my wife's 2006 (early model) Kia Optima (same as pre-2005 Sonata) had a vibration, fluctuating RPM and then it stalled.When it stalled we saw al lights on the instrument panel light up. No check engine light stayed after staring it again.We drove for a few minutes and it died again.
I opened the hood on the safety lane and checked the battery poles and belts.I could not see anything out of the ordinary. But my wife said a day before a bird flew in front of the car's grille and she found the bird's skeleton at the driveway that evening.
We drove the car home without problem. 15 minutes or so. No check engine light.
What could be the problem?
I am using Mobil 1 Extended Performance oil for almost 8,000 miles now. With synthetic oil my usual oil change interval is 7-8,000 miles usually.

paterick i have a 01 4cyl. sonata with 189000 m. on it and it has been a great car. to buy one that has been taken care of i dont think u can go wrong. the power issue is if u are going to drag race it dont buy it , if you are close to sane it should do u real good . mine still gets 25-27 mpg on a lond trip and it can get out of its own way. if u can find a v6 mod rl i would go that way but dont be concerned about the 4cyls. om min e i have had to replace both rear wheel bearing packs at 95000. the mech. said that was alittle early but no problems since. be sure when u buy a front wheel drive car have the cv joint boots inspected that they have NO tears because they hold grease for those cv joints, no grease the joints go bad and its 2-300$ per side to fix. so yes i highly recomend hyundais and i am a GM guy. good luck and happy car hunting.

#2954 of 2955 Hi-Beams turn on randomly while keys are out of ignition.
Nov 15, 2011 (6:27 pm)
So I just purchased a 2003 Hyundai Sonata GLS and everything has been working as it should. The car is about to have 160,000 miles but is still running great. Today I noticed that my hi-beam was still on when I got out of my car. I toggled it a few times and if finally submitted and turned off (oh I also only have one hi-beam working). Also the headlights do not even seem bright while on normal and driving. So I have been outside working on it and I noticed that my AC unit lights stay on with my bright lights. But when I turn my AC knob past 0 and keep it on 1,2,3, or 4 then I cant turn off my bright lights (key is still out of ignition) I also can turn on my high beams while car is off by turning my AC knob clockwise to the numbers 1,2,3, or 4. It seems to be a short but I have no clue if this is something that happens when one bright light is burnt out or if a relay has gone bad. Any thoughts on this please help me? Thanks for reading.
