Kia - Optima :: Headlights Flickering - All Lights Fades Out On Pressing Brakes
Aug 4, 2013
I have a 2002 Kia Optima. The headlights have been flickering as well as every light inside the car. When they're doing this, if I press on the brakes, everything fades out. Such as the radio, headlights get very dim, air conditioner fades out. The car almost comes to the point of stalling. I've had the alternator replaced but the problem continued. I have asked several mechanics but they are baffled.

I had H&R springs installed today. I have a problem now. When driving with the headlights on i noticed that while braking the self leveling in our headlights seem to be freaking out. Every time I press the breaks the lights are constantly trying to adjust. What this could be?

I recently purchased a 2011 Sonata GLS and I love it. However, I'm having a slight electrical issue.
While driving at night with the headlights on occasionally they'll dim and flicker and often cut off completely while driving or parked. The interior and dash lights will also switch off with the headlights, however the radio will still continue to play. The lights only stay off for a second and then come back on. Sometimes I can make them flicker and go off by turning on my blinker or switching between high and low beams.
I'm trying to figure out if it's a problem with the alternator, the battery, or the fuses and if this is a known issue.

I will start out with a little history of the situation. A little over three months ago my original altenator died with over 200,000 miles on it. I took it in and had it replaced (they used a refurbished altenator) and about a 1-1/2 months later is when the issue started. The headlights and dash lights will flicker and whenever they dim, the volt gauge will go down.
When the lights come back to normal brightness the volt guage will also go back to normal. All this will go on for random lengths of time as I am driving. I took the vehicle back to where I had the altenator replaced and they replaced it again under warranty. About another 1-1/2 months went by and the same thing started happening. I took it back to the same garage and this time they put in a brand new altenator. Finally about a week after this last visit to the garage the symptoms came back.

I've had my '07 Volvo S40 2.4i for almost a year. It has a little over 60K miles on it and is serviced regularly. Within the last 3 months, I've noticed some weird things happening occasionally:
-Trouble starting when cold (I understand this is pretty common with a lot of cars.)
-Headlights & interior lights flickering
-Going over "bumps" in road causing dash display lights to illuminate for a second, radio to shut off, and loud system "BEEP" comes through the speakers (this has happened 3 times total, all on the same day.)
-AC stops cooling periodically I've had the system scanned for the AC issue and it seems that there was a "Pump pressure" message that cleared itself at one point and am guessing the same thing has happened the next few times it's done this.
I also asked that the battery be checked to see if it needed to be replaced soon. The mechanic said the battery was fine and thinks it's something wrong with the entire electrical system.

Ford Focus 2004 manual 150K miles. Most days the car runs fine. Other days it will start and run until it warms up, then stumbles or hesitates at speed. When this happens the headlights and dash lights are also flickering. Sometimes i hear a clicking sound behind dash, left side. I have the sure cure: turn the heater fan to high. This works every time. When the engine is hesitating, i turn the fan to 4-high, the engine smooths out. Turn the fan down, engine again hesitates. Hesitates at 3, worse at 2, worst at 1. It seems to need the extra load.
But after few minutes of high heater fan, the alternator light comes on. I flick the heater switch down, endure the hesitation for a few seconds, the alternator light goes out, engine still hesitating, flick the fan to high, engine smooths out. A few months ago i could get it to fun smoothly with the fan on 3, didn't need 4-high. Now seems to need 4.On the days when it is always running smoothly, the heater fan can be on any speed, the alternator light does not come on.
Next few days or even weeks the engine will run smoothly, no hesitation, with the fan on or off or any setting.
The car has been to three shops in past year, one of them a major Ford dealer, who kept it two weeks. The problem has been diagnosed as battery (replaced), Battery connections (checked), plugs (replaced), fuel pump controller (replaced), fuel pump (replaced - ouch!), alternator (replaced twice - ouch twice), grounds (checked). Every time they "fix" something the car runs ok for a week or so.OBD shows P2004 (intake manifold runner stuck) but all agree it can't be the problem.
There have been a few times when i flicked the heater fan to high that all the dash lights died, fan went off, headlights off, turn signals didnt' work, but the engine ran smoothly. Not so good on the highway at night!There have been a few time, not recently, when the car wouldn't start. No dome lights, no dash lights with key turned to ON, no clicking or starter with key turned to START. It acted as if my battery was missing. The cure was to turn the headlights on. All normal after that.

I have a 2004 Ford Expedition and today on the freeway I had to step on the brakes pretty hard to avoid an accident. After pressing, the pedal resistance became really soft and the brakes worked, but were very sensitive (a lot of pedal movement to brake). I had this happen some time ago and I did a complete system flush and no problems since then, but it has to do with how hard I hit the brakes. What could be wrong????? BTW - I never noticed the anti-lock brake pedal pulse at all during this event. I'm not even sure it is working at this point. No dash lights to indicate an error of any sort.

Random question, when you are stopped and pull your e-brake do your headlights turn off? I feel like they did in my 20th but I can't recall. If they do, mine isn't working,my e-brake light also does not come on when pulled.

Can I just replace the bulb to fix the flickering problem with the HID headlights? Before it was once in a while but not it's more then I would like. I think the problem might be the bulbs vs the auto leveling (I don't see it moving in a park position).

I just lowered my car with H&R springs and I did the flash to pass vagcom change. When the car is still and I turn on the high beams or flash it, everything is fine. Is when I start moving, and then put the highbeams or flash it when the xenons starts flickering mimicking a strobe light and is giving me an error message on the display, right or left beam dipped error.

I noticed last night on my way home from work that my headlights were flickering. I looked and also noticed my amp meter was also fluxuating. The car seemed to be running fine asside from the lights kept flickering. It did not make a difference what RPMs I was running, or even if the car was moving. My 2000 Bonneville has the original alternator and 181k on her...

I just recently had the hybrid battery replaced in the my 06 Prius. Probably about 2 years ago I had my right headlight replaced because it kept going out. Well now my headlight is back to going out again. However no it's no longer just the right headlight. It can be either. It doesn't seem to matter if it's smooth road or bumpy. Seems to do it alittle worse on really cold days but it's also done it on a couple 40 degree days we had recently.
The left headlight has a habit of flickering alot. Some times it'll stop and stay on, other time's it'll flicker and then go out. When the right headlight goes out, it doesn't flicker, it just goes out. If I turn the lights off and right back on, both headlights come on. They may stay on rest of way to work after that or they may stay on 5 minutes. It is something I can check via navigation console? Is my only option to take it to a Toyota dealer?

2006 ~ Noticed the car lights (head lights only) flickering off for a few seconds while driving at night, took it in and they re-set the computer, still is flickering. Without spending 4 hours in labor for them to check every wire?

Past week I have noticed a flicker on all lighting (head/taillights, interior lights) on my '06 Sonata (4cyl). Seems to be an intermittent problem, as one time in three there is no flicker, and everything seems to be fine.
Yesterday, when pulling into my driveway, I momentarily lost all lighting/radio/fan for what seemed to me a full second and a half before everything "came back on".
I've checked fuses, battery cables (batty is new, 6mos)... Is this alternator related? What else should I be looking at? My Sonata has been bulletproof. No mechanical issues whatsoever....

I've got a '99 GMC Sonoma that I purchased last summer. Great little rig, runs well and the previous owner took care of it. In the last couple of days the headlights and dashboard display have been flickering at all RPMs. I am guessing a bad battery or alternator, but previous related posts indicate it could be all sorts of stuff electrical.
From what I can tell from previous posts, the easier tests are
1) Voltage across the battery poles with engine off to test for a bad cell,
2) AC voltage at battery with engine running to test for alternator diode problems (should be no AC voltage, correct?), or
3) Something called the A.I.R. pump, which I've never heard of and wouldn't know how to test.
The last time I had this happen was on a 2000 Caravan, and it was the battery.

Anyways, My 2001 Windstar has been acting up recently mainly the headlights flickering every now and then, car randomly stalling out on me - after it dies, I pull over and start it up right away and the ABS light came on.
Check engine light is on (presumably due to the car stalling out) but I do not seem to be able to read the codes, the code reader is working fine on my 2001 Expedition but on the Windstar it just sites there at 'connecting to vehicle'. I've tried disconnecting the battery for 10-15 mins and this made no difference, I also checked the fuse for the port was good so now I'm not sure what to check next.

I am a new 2013 Lexus ES 350 owner. I've notices when I'm driving at 55mph and above that when I press the brake when approaching a stop light or stop sign I can feel a vibrations, the steering wheel doesn't vibrate and the car itself doesn't tremble but I can feel it in my foot. My husband said it could be the ABS. Maybe it's totally normal.
