Have Toyota Questions? Ask a Mechanic for Answers ASAP
Do you have a recording of the noise? Noises are hard to diagnose in tis type of format? Do you have the VIN available?
Is the noise loud enough to get a recording of it and post it here?
Given your description you probably wouldn't hear the noise from a recording anyway. That being said I checked multiple service bulletins for this type of noise 2007 through 2009 had a lot of issues with weeks rattles popping noises and so on. There is one particular service bulletin number T-SB-0327-08 that does fit your description it had to do it a rattle growling type noise on acceleration from the center exhaust pipe. It's possible that noise is coming from there. If you Google that TSB number you can find a copy of it online.
Okay, let me know how goes there are couple of the things as far as service bulletins one for the brake booster and on for the upper windshield glass to molding attaching strip. It can cause a growling or buzzing noise but that's typically right along the instrument panel where you hear the noise sometimes it resonates up towards the roof lining.
