My electrical issues started with lights flickering while driving as well as dashboard lights becoming very weak and flickering as well. Sometimes when I start the car my trip computer goes back to zero and my temperature settings are lost. Then lately after shutting off the car the remote would not shut the doors, as if no electrical power in the car. When this happens the car would not re-start (no power at all). I found out that I have to remove the main relay for about 10 seconds for it to start again. Battery is less than 2 yrs old. I was told maybe the alternator, which I did change, but that did not fix the problem. Weird thing is sometimes the car is fine for a week, then it happens again.
Any idea what could be the issue? Any feedback will be helpful.
Thank you,

Corrosion can play havoc on the electrical systems.
Clean contacts and terminals. All Grounding points.
Both battery negative and engine straps.
Then troubleshooting the intermittent issue should be easier.

Good luck

Thanks for your advice. I did not mention it in my previous post but I already cleaned the grounds. After reading many posts, it seems that voltage drop is common on the Azera. I am just wondering if the flickering lights and the car not starting are both related to the same issue or Do I have two separate problems ( failing starter) being one of them.

It would be more likely to be a failing alternator causing flickering lights.
If you change the alternator then be sure to charge the battery back up
If you use alternator to charge up dead battery then it can work the alternator very hard.
Also check battery to make sue it is good. Don't want a dead battery to take out a second alternator

Are you having a no crank, no start?

Good luck

If a failing alternator is your issue, and it very well might be (sounds like my symptoms last year for a different root cause), you might want to inspect for valve cover leakage (common problem leaking into the alternator) which may be causing your failure. In my case, it was self induced with a pressure washer and Simple Green in the soap reservoir because even at nearly 300K miles, my engine bay still needs to look pristine (lesson learned, rather noted...not really LOL).

Cheers,

IN fact, it was the valve cover leakage that led me think that my alternator was faulty but even after replacing it the symptoms remain the same: flickering dashboard, radio shutting off and restarting, trip odometer resets to 0 when I start the car, car refusing to start sometimes...All these symptoms make me think there has to be a short somewhere.

2006... crappy cable between alternator and battery.. engine running, stick battery for voltage..

Now move red test lead to alternator stud...

You likely a straggler that not had cable replaced... the cable assembly now pushing almost $300,, they was maybe 1/2 that some 8-10 yr ago.. look at part tag on cable near battery tray,,, new cable is "-3K111" I think it is..

Check voltage at battery with engine running,, red lead stay on battery,, and move black test lead to engine metal, compare voltage,, do same key off also

Remove lug from body panel and grind paint away, slap some grease on bare metal, and put lug back in place

Still have pile of old cables here I have not yet skinned out for copper wire scrap yet

I literally just got done dealing with that headache. Let me save you some time, money, and headache.

Your problem is your + battery wiring assembly. I changed everything trying to figure this out alternator, new battery, new terminal connectors, almost every fuse.
Last resort I ordered one off of Ebay for 70$. They are 300 if you buy them local. It came from South Korea, had to wait 2-3wks but it fixed it runs like a champ.
Give me a few and I'll get you the part number

I'm no mechanic by any means if something doesn't work I change it.
It seems you change a lot of other parts that actually do work too though <img src="http://www.hyundai-forums.com/images/Hyundai-Forums_2014/smilies/tango_face_devil.png" border="0" alt="" title="Devil" class="inlineimg" />

Process of eliminating the problem I have taken my azera to mechanics for this problem they could never figure it out. But the way I see it is I still have all those parts that still work so if they do go out guess what I'm not sitting and waiting for someone to fix my car. I already have the parts and know how to get it done. Plus money isn't a issue and I'd rather do the work myself v.s. pay a mechanic 1-3k to do what I did for a few hundred. Plus mechanics may fix a problem and create a new one without you ever knowing until it's too late so mock me if you must but i would rather keep my extra money in my pocket. I'm giving advice on my 06 that I completely rebuilt. The other thread is on my 07 that I'm working on now. My 09 and 2017 work fine. My 06 and 07 are my favorites so please leave your negativity elsewhere

hi friends , I own an azera 2008, and I recently have electrical problems such as flickering headlights and dashboard lights. While driving at night, the headlights are completely dim for 2 seconds and then return to normal.The car's electric power fluctuates sharply and finds that there is a fault in the electrical system.
Sometimes, even for a few days, there is no problem.
When the problem was visible, I checked the battery and the alternator , and I realized that the alternator would not charge much and the voltmeter was 13.3 volt.I turned off the car and turned it on again and checked it again and the battery was recharged to normal and the voltmeter was 14.4.
Has anyone experienced the same problem? I appreciate your help in advance
