Hyundai Santa Fe Electrical Problems
2001 Hyundai Santa Fe, with only 57,000. I bought it 5 months ago, and noticed when I drive at night (mainly) if I press any button in my car, and even the brakes, the car lights with dim, and almost sound like it is going to kill my car. Then a few days ago while idling my RPMs would drop really low, and the radio as well as lights would dim, and the car almost sounded like it was about to stall. Please some one help me.
When I got home and turned the engine off, I re-started and everything was fine. Turned the ESC off then back on and it worked normally.
Assuming it wa a temporary short from high water spraying up, and after I had to have my external Temperature Sensor replaced after going through a car wash when i first got the car, I'm wondering if there is any shielding to the on board computer and wiring.
Anyone else had similar problems in the wet - i.e. temporary shorts, replaced temp. sensors?
Any ideas for a "shady tree" wrencher to try???
Am having similar problem with 2007 Santa Fe. Does anyone know more about this? Dealership says it cannot find cause / problem. I don't think they believe me. Is Hyundai America aware of this issue?
Is there a connection between car stereo and parking light?
If not what may be the course of this kind of problem?
How can I fix this kind problem? I do not want to rush to an electrician again without doing some findings.
Please, information from any body is appreciated.
Think I found the answer. It appears it has to do with alarming the vehicle. The driver side sensor is the alarm and the passenger side is the automatic light sensor. Anyone wish to confirm my thoughts?
Thanks in advance.
I have a 2009 Santa Fe SE and mine does the same thing as yours when the alarm is activated. Only the driver side blinks red. Hope this helps.
I have tried to locate a buss that has an increased rating but without any luck!
Thanks for any help
Let me know if you found the problem...I plan to take it in tomorrow to my mechanic.
I'd love to hear what happens with your lights. I recently took it to a shop and they thought it was the light switch. They replaced it and still had the problem. Luckily they put the old one back on and didn't charge me a thing. I've read on other forums that the dealer will replace the BCM (body control module), and it doesn't always fix the problem. That runs over $1000, so I'm not willing to take that kind of an investment on something that may not work. I've also read somewhere that someone had the problem fixed by cleaning the grounding straps. I tried talking a shop into doing this for me, but they wanted nothing to do with the problem outside of replacing the switch. I'm going to try and find another shop to go to and see what they say. I'll keep posting any new info I get on here.
Hopefully we can get this straightened out together.
