Both my lowbeam bulbs went out at the same time on my 2011 back around 48k miles. I believe I read there is a TSB on this issue along with a strange engine rattle at startup.
View 5 RepliesSo I've noticed this alarming engine rattle when I first start car as if there is no oil? It only lasts a few seconds! Was it diagnosed with Hyundai? Maybe a quirk of the motor, but seems like over time would cause excessive wear on engine?
View 14 RepliesMy car is having a problem of passenger side light (low beam) being always on even after turning the switch or engine off. I have to unplug it to prevent it from draining the battery.
I am not too familiar with electrical system on the Prius, but suspect bad relay or something related. Where the relay for the headlight is?
I once experienced the noisy engine start up.. It sounded like the engine was trying to run backwards or severe pre-ignition.
View 2 RepliesInitially thought that this was related to some water in the tank, since it started when the gas dropped to 1 bar (already put some stuff HEET when put the whole tank, did 60miles so far). ODB throws out multiple cylinder misfire (codes 300, 301, 302, 303 etc). It lasts up to 3 seconds. Sometimes the check engine pops up sometimes it doesn't. there was absolutely no problem under load. does it seem like a fairly common problem ? Intake manifold clogged ?
View 14 RepliesI have driven 25,xxx miles on my 2010 Prius. Three times during the last thousand miles I have experienced very loud and scary engine noises during start up. The car had sat for at least ten hours outside in 20-30 degree weather.
I took the car into the dealership for an oil change and my service advisor told me that Toyota was aware of the problem and the noise was not coming from the engine- but a device that mates the ICE with the electric engine. He told me that although it was a loud and dangerous sounding noise, it was not something that would harm my motor. I asked that the noise be logged into my service record.
I have a 2006 VW Passat which has been eating low beam bulbs. I've probably replaced this one 4 times in the last 12 months. The last time I replaced was 2 days ago with a Sylvania bulb. Yesterday on my way to work it burnt out. Then on my way home last night I was pulled over by a cop for it. That really annoyed me.
Having issue with Passat burning through headlight bulbs? Do I need to have the wiring assembly checked or possibly replace the entire headlight assembly? I'm getting really tired of changing these bulbs so often.
My 2010 Prius V just past the 24000km mark. I have a buzzing noise coming from the engine bay during startup. It happens when the interior fan is on. You can hear it clearly after you start the car, during the silence of the "boot up", before the ICE kicks in. I can't be sure if it continues to buzz after that because the sound of the ICE drowns it out. However, If I shut off the fan during the boot up, the buzz disappears. Finally, if I leave the fan off and start the car, there is no buzz.
During a recent oil change, a hybrid technician claims that this is normal. It used to happen infrequently but now it is consistent, so if it was normal, I should have heard it when the car was new.
I'm having a trouble when accelerating at low rpm the engine begins to rattle. Tried removing the connector plug on the egr, to my surprise the rattle is gone but the engine light comes on saying that the EGR circuit is incomplete. Took it to the dealer and they diagnosed it to be the EGR valve opening but failing to close, so they instead proposed to fill in gas with a bottle of their injector cleaner. That made no difference, so tried replacing the EGR valve but again makes no difference. What could the culprit be?
View 11 RepliesJust started getting this noise recently when I start the car. It's coming from the engine bay and only occurs briefly for maybe a second, mainly when the engine is warm. It's a rattle sound. Other than the rattle, the car runs great..

2010 Prius engine start stumble - YouTube
Started out with no code, then check engine light started coming on. P0301, misfire cylinder #1. Sparkplugs were replaced, and coil pack for #1 switched with known good one. EGR tube also cleaned of carbon.
Stumbling/roughness has been getting worse, about an inch of coolant used per week of driving. No oil in the coolant, and no coolant in the oil (no milkshake or anything like that).
Dirty fuel injectors were suspected, but no improvement after using Techron. Finally, a boroscope was used to inspect the cylinders through the sparkplug holes, and a very slow leak was found in cylinder #1. Since liquid cannot be compressed, during the compression cycle significant misfiring occurs.
So lately I've been hearing what sounds like a slight lifter knock that develops at 1500 rpm to 2700 (I have ultragauge) when accelerating or maintain speed, and it only appears when the engine is at operating temp and disappears when rpm is below 1500 rpm and above 2500 rpm my oil is running at 3900 miles using Toyota synt 0W-20 and it looks pretty clean and at high mark of the dip stick.
View 3 RepliesI saw some other threads lately other people having startup problems thought i would post mines as well. Mines sometimes would startup then rattle alot/Car shakes and spit excessive smoke from tail pipe. Then sometimes it would startup up at all, No crank No Check Engine Light either

So I have searched about engine rattle/knock and I have found lots of results for cold starts but I haven't found it for the issue that I am having. I have a 2010 and anytime the battery is real low, around 2 bars and the ICE fires up to charge it, any time I give it a little throttle input, I get heavy valve rattling. It doesn't matter if its cold or hot, it does it as long as the battery is low. I never get this noise when battery is charged up, only when low. I have a link to the video below and you can see once I give it some input, it starts to sound like an old diesel tractor. Prius has close to 200K on the odometer and all my maintenance is up to date. Please turn the speakers up but the noise is right at 5 seconds in or so.
View 13 RepliesI've been recently having the engine rattle/knock noise occasionally when I start the car. After my first oil change, I mentioned this to the dealer and demonstrated this to them while they documented the issue. I left my car at the dealership for investigation.
The following day, my dealer said they called Toyota and created a case about this. Toyota responded saying they heard about this and the possible root cause is the Motor Mounts on the Prius. They will be sending parts (date is still unknown) to fix the issue. :rockon:
I specifically asked if there is any damage to the engine and they said absolutely not and there is nothing wrong internally with the car. This also makes kinda sense because if I press the accelerator to the ground when it starts up, the knock doesn't appear. It also works if I put the car into D and drive away.

How do they make the high beams dim for Daytime Running Lights?

View 14 RepliesI notice some Prius are using white light beans. Are those LED light bulbs? If so, where can I find them? I search eBay and I do not find any.
View 3 RepliesThere was a TSB for 2AR engine, Engine Knock/Rattle Noise at Cold Startup. My question is for those I4 camry owner, do you have these rattle sound when you start your vehicle at cold? I am not sure if mines have the same issue, but pretty sure is I can't find any differences between mine and this clip:

So should I take it to the dealer? Or it's normal?

I've had HyperWhite bulbs on previous cars and they're great. Much whiter than the "yellow" factory bulbs.
What would be a close color match to my LED parking light which looks sort of bluish? The new parking light LEDs are 6000K color temperature.
