Does anyone know the reason for it?

Please....><

Obviously no one knows what it is. It's kind of hard to figure out from that description. Maybe if you can get some video of it or something someone can figure it out. You should take it to the dealer, since it's a 2009, it's still under warranty.

Thank you everyone...thank you
I will take it to the dealer....
Actually do I have to pay for a check up because of it?
It seems so non sense if they charge me as I only got my car for a week only

[CtrlAltDefeat]

I seriously doubt it... but don't take my word for absolute, because I don't know for sure...

Check your oil level. The valves could be noisy if the engine is cold, especially if you have run low on oil before.

Lafiro,

When did you start to have this duh duh duh sounding problem to your Yaris? My car has only 400 miles on it in total.....

my car is just a week, every tank is full as I checked it today....

[highwaypass]

once,it happened to me too.Each time i put my transmission to neutral,it goes same as yours.
Mine was 1.5 hb M/T. When i check it to my dealer,they say that they just do some lubrication to the gearbox.I dunno what parts,but it works well with mine.

I see....thanks,
I start to realize that it happen at the beginning I start the engine. After I speed up several time, the weird vibrating sound disappear. It happens again when I turn off the engine for about half an hour to 45 mins.
I just talked to my dealer today and they suggest me to leave my car for them overnight....
so they can let the car cool down and check it.
I am going to do it on Saturday.

[highwaypass]

Good luck then,and welcome to yaris!

My car has had that vibration every since I bought it.

As for the bad sound some of the time, under 2000k rpm, especially if there is strain on the engine I just found out, like going up a hill; this has only been an issue of rmaybe the last month or two at the most. Same time I know I have to change the oil.


So what is this that I should not use royal purple, nor use the stock air filter in the box?

Wow, what should I use then because I plan on buying the oil today or monday at the latest.

[soup1207]

I got my car back from dealer and they can't even hear the vibration.....
the noise seems got disappear in a shorter time than before although they still happens.

Lafiro, do you mean that every time you hear that noise you would go to have oil change?

No, It does that all the time.
Its hard to explain because my car has a few problems.


******First off, from 1400-1800RPM, especially taking off, and on a slight hill, my engine sounds like the valves aren't getting enough oil and sounds like they are stuggling bad. After a little more gas, and higher RPM, it goes away.

******Another problem is that in nuetral, the car vibrates at about 1800RPM.

Another problem, usually only after the car is used, is that when I come to a ******stop, the car is sqeaking a lot.
This I can replicate by driving the car, stopping, and opening my windows, or even just my door, or better yet, sitting next to a brick wall, like a garage or a drive thru. Its very annoying, and I cant figure out whats causing the noise. It goes away though after the car sits for a bit, or I take it out of D/R.

I have that same weird metallic sound coming from the engine bay as well. Mine started after I hit a concrete block on the freeway at 60 mph. It doesn't appear when I'm in neutral, only appears when I'm driving around 2k and 4k rpm. Nothing was damaged other than my front bumper and some plastic panels under the front bumper, so I have no clue what it is.

[IllusionX]

Actually.. i heard some vibrations when accelerating from 2krpm or below. I heard it most when i have the rear seat flipped down.

probably just the muffler rocking around..

[soup1207]

The dealer said they can't hear any sound and put my case on record. They ask me check again when the first time oil change has come.

Would they charge me if they finally find out the problem at the time I have my first time oil change? The problem started to happen at the first week I got the car.

Here is my situation. If you got any clue after seeing it, please let me know. I also sent it to my dealer as they said they don't hear any noise for the last road test....><
