So, I was planning on selling my '05 TL Base 6spd M/T, but decided to keep....ONLY if I can figure out wth is going on with it. There are a few problems, so stick with me!

1) HID's. They have flickered, strobed, and straight up cut out in the past, but for the past month...I've had absolutely ZERO issues. Whether I'm driving hard, slow, normal, day, night. Doesn't matter. But...I'm waiting for it to happen again. I replaced bulbs, ignitors, and ballasts. Even after all that, I still had issues and couldn't pinpoint it. But, for the last month it's been flawless so....idk. Nervous it's only a matter of time before it surfaces again.

2) Fog light switch. When I go to twist the fog light switch on my turn signal stem, and I twist it even the slightest bit past the ON position or bump it when turning the turn signal on, it will cause my fog lights to turn off. I have to be extra careful not to bump it. So, assuming it's a loose wire/poor connection, how simple is it to fix?

3) Both my key fobs won't bring up memory settings. For instance, I use my fob 1 key always (tried both to troubleshoot if it was the one key fob or the car) and the memory light on the door never lights up anymore. The display doesn't say "Driver 1 Detected" anymore. I have to hit the memory setting button manually. It's not a huge issue but, it's annoying and not sure if it's related to the fact that every time I turn my lights on, the lights dim to the brightest setting. I never had to adjust it. They used to always dim to where I had it set. I can set it, then as soon as the car sits off for a minute, I turn the car back on and they're set to the brightest setting again (NOT Max, just the 10/10 on the scale thing). Battery is fine, alternator is fine...so I'm confused.

4) Every once in awhile, my radio favorites, reorganize themselves. I have not even the slightest clue why, but my number 6 favorite on FM2 somehow ended up my number 1 favorite on FM1 lol That had me bewildered.

5) Airbag light comes on sometimes randomly. It doesn't matter if someone (or something heavy) is in the seat or not. And I can drive 100miles and it never come on, but the next day I could drive 2 and it pops up.

6) VSA & TC lights come on for some reason. I had them off for the longest time and took it to a shop for them to look at my HID's when they were strobing (they couldn't figure it out either), and ever since they hooked it up to their computer, I can't get them to turn off. I've checked it for codes with a scanner I have at home (I've had it working before on this car and it's shown me codes, so I know it works) and I can't get any codes to pop up.

So, anyone have anything for me?? I love the car, but really it's an annoying, electrical nightmare. I'm taking the engine & trans out this winter to replace motor/trans mounts and new rear main seal in it. Might trace wires then, but I absolutely despise wiring work.

Thanks.

 

Oh one more thing. Every once and awhile I will go to lock my doors for a second time that it beeps, and it won't. It comes and goes. I've tried checking all the doors, trunk, hood. It randomly comes and goes so...*SHRUG*

 

I would check the gounding points in the engine bay and any under the dash that might be loose.

 

bad battery or alternator perhaps

 

Lighting issie may be faulty headlight/foglight swtich...

My 2008 would ocassionally do crap like this... Memory seats would not work, them would... Auto windows didn't work once for 5 mins... Alarm went off upon inserting key once...

Fixed it with a newer Kia Optima, haha!!!

Also, my 2007 RDX acts up all of the time too, welcone to Acurat!!!

 

Will check, thanks.

This started a year ago with a 2 month old battery. Never had any battery issues until less than 5k miles ago when the alternator went up. Replaced alternator and trickle charged battery back to full. No issues with the battery, but lights still do same thing every once in awhile.

Haha oh good. I'll just replace the entire chassis wiring harness....lol

 

Also, my battery would unexpectedly die, or not... Usually, I could get it to click like hell then start by flooring it while letting the starter crank...


BTW, this happened like 25-40 times!!! Sitting in the car lisiting to the radio for more than 20 mins is lethal, also, stupid clock only illuminates with ignition, do that a few times just to see the clock, you're dead in the water, bro!!!
