Prius (2004-09) :: Left Headlight Go Out Frequently?
May 18, 2014
I have a 2009 prius with 85k miles on it, bought it two weeks ago, right off the bat I noticed that the left headlight, while driving, will frequently go out. It comes back on when I turn the headlights off and on again, and goes out again later.
Sometimes it stays on, other times it goes right out. I took the headlamp off, disconnected all wires, and cleaned it of any corrosion that was found and reconnected it, and the light still went out. What would be causing this/ what a fix is non mechanic oriented?
Worth mentioning that I've noticed condensation build up on the inside of the headlamp occasionally, and one time both lights flickered and then went out, but that hasn't happened since.

I am not sure if I should be worried but I noticed that my left headlight and my right left tail light have both gone at about the same time.

I understand the engine turns on and off frequently (coming to a stop it turns off, then when going it turns on). I have noticed that sometimes when at the stop it will turn off, then immediately back on, and off again, even with my foot on the break.

While I am driving my left headlight keeps turning off and to turn it back on I just have to flip the lights off then on again. I have a 2005 Prius with 160k miles. What part of my car is potentially broken and whether it is a feasible DIY project or not.

My Prius is a 2012 Two model. The headlight is my low beam on the left side. Is this something I can so myself?

I have a 2004 Prius with about 50K miles. It is driven every day. I recently noticed that the motor doesn't shut off as frequently as it used to when I stop at a light. It then also shows the battery as almost empty (1 bar) on the touch screen. Gas mileage also seems to be a little lower than it used to be. Other than that the car drives fine. Could this be an indication of the battery starting to go?

During the last week, or slightly less I suddenly started hearing the brake boost pump running much more frequently than normal in my 2008 and is also producing a "knocking" noise along with its run noise which increases in frequency as the pump speed increases. No problems with the engine coolant pump for the thermos, and the inverter pump was replaced yesterday along with a replaced "bolt" in the steering column for the recall.

I have a 2004 Acura TL which has been in pretty good shape up until recently.
The left headlight started working on and off spontaneously. I also have noticed that the rear power door locks have been very "sluggish." Meaning they sound like they are just not powerful enough to unlock the door and often take about 5 or more cycles of lock/unlock to finally work.
I took it to the Acura dealer to take a look at the headlight, and they ran the diagnostic kit and said it looked like I had a faulty headlight electrical setup. They said the bulb, igniter, and ballast, and even the car battery were bad and needed to be replaced.
My question is did the faulty battery cause this? And could my USB cigarette lighter adapter for my phone charger cause a drain on my battery to wear it down? The charger doesn't seem to use any electricity unless the phone is plugged in and the car running (a light comes on). Or anything else you can think of?
The lesson I've learned for my next car is to get one with normal headlights and normal size rims. (the 17" tires are annoyingly expensive!)

For a little over a month now, the front left turn signal has gone out at least once a week. I have been continuing to buy new bulbs for it, and it would run for a few days, then quit on me again. Just today, it happened again, I replaced the bulb, but this time it still isn't working. Ive tried clearing some of the crud off of the inside of the socket, but nothing seems to be working, and now im down a turn signal.

I just bought a new 2010 Prius IV and noticed after a good rain that the front left headlight assembly was showing some moisture fogging inside the lens. None of the other light assemblies showed any moisture.

I have my daytime running lights on all the time since purchase in 2004 - this is the first time I am changing any kind of bulb on the car.Headlights are ok when starting car, but after it warms up the headlight goes off. Took it to my local repair shop and they said the connector was loose but that night the headlight was off again.

Bought an 04 a couple of weeks ago and the passenger side headlight is way high.I turned the adjustment knob and it does nothing.The drivers side light is fine,but out of curiosity I turned that knob and it didn't do anything either.I'm thinking about buying an aftermarket assembly.

Every now and then one of the HID headlights goes out on our 2006 Prius, seems to be a random event not favoring either headlight. Shutting the headlights off, then turning them back on again corrects the issue. The problem with using this fix is that it isn't good for the HID bulb.

I have a 2009 Prius with about 36,500 miles on it. I dropped a friend off at the airport tonight and noticed in the reflection of the car in front of me that my right headlight was out -- a fact my friend confirmed when he got out of the car.

One of the headlights will turn off after some driving time. If I turn the light off and on it will come back on. Asked Toyota, of course they said it is because you are not using OEM Toyota bulbs. I have the same bulbs on both sides. I even replaced the bulb on the "bad side".
Still the same issue. If the bulb is the problem, it would just be off, why it comes back on after "off/on" exercise? Another symptom I saw last week. When switching to high beam light both lights go off. "Off/on" of the car resolved this. This happened only once though.
The car was in the front accident 2 years ago and Toyota repaired it with life time warranty. But I am not sure if it related or not and how to convince Toyota that there is an issue here and not a "bulb" issue.

I've had the car a little over a month. First 1000 miles were smooth (55mpg), but I have noticed that the ICE kicks in a lot more frequently now. I might be driving it incorrectly, but I've noticed my mpgs drop to under 50 for the last 800 miles driving the same commute. For an extreme example of the revving: I go to the store. Get out of the car for as little as 10 minutes after the car has been driven 15 miles or so — and even though the battery is more than half way charged, the ICE kicks once I start moving from my spot.
Even if I'm just moving from one part of the parking lot to another going less than 10 mph. When I let off the gas, the ICE continues to run even after I come to a stop.
Now I know it's getting colder (highs in the lower 50s these days), so I expect this in the morning after it sits out all night. But I don't remember this happening when I first got it (granted, it was warmer in mid Sept here).

I have a 2004 5.4 and the A/C cycles on and off too frequently making it take too long to cool the cab. Had A/C service done this weekend and initially I thought it worked, but now a few days later, it still cycles on and off. Is this a simple relay or switch somewhere?

The passenger side headlight of my fiance's 2007 Prius keeps going out intermittently. It's a touring model with HID's. I replaced the bulb already and the problem persists. I searched and found that there is a TSB about it [URL]...................... It sounds like it's either the bulb (which I replaced), the wiring, or the HID ECU.

As I stated in my other (and only) post... I just bought a used 2008 Prius. Tonight I noticed the driver's side headlight is out. I went to Autozone and they told me I needed a $10.99 replacement bulb...
I bought it... took a quick look and couldn't see how to get to it - so I put it away for the night...Now I see on here there is some sort of "bulb issue" with Toyota?
