are these engines known for being a little noisy
i have noticed that when im going roughly 1/2 to 3/4 throttle through the gears in auto mode just between shifts i can hear a little bit of noise that almost sounds like a rattle. i had a bad batch of gas one day and it was even more noticeable. i thought maybe there was something loose, but that wasnt the case as far as i could tell. it could be valve train noise, but im not sure. i read in a review that the engine was somewhat noisy as well, and im trying to find that article now. its not neccessarily a concern since there is the warranty, but id like to know if its typical or not. thanks

if it was some thing in the block you would hear it at high revs/heave loads,
if ur hearing it between shifts i could be a tranny issue.
bring it to the dealer and say "fix it", if you don't do that, at leaset call them and log a complaint, in case ur tranny falls out later you can say i made a complaint about it.

If it's between shifts no, mine doesn't rattle.

its during shifts. just as its changing gears under partial throttle is when i can hear it, and in the low shifts like you mentioned. is it just a noisy engine, or is this a problem that needs to be fixed? thanks for the reply, and can you direct me to any links of other threads talking about it?

The VQ has always been recognized as a louder motor. Other motors in it's class are belt driven, whereas ours is chain. Yes, a Lexus is FAR quieter.

Please don't think I'm trying to defend our competition, but the truth is truth. Historically Lexus' are silent, whereas Infiniti's old Q flagship still had a nice V8 exhaust tone.
Silence is beauty to some, whereas engine noise is to others.
