I have front dash rattle while going on uneven road. I have no idea where exactly it came from.
Anyone has similar issue and know where it might be?

Thanks

 

My dash is rock solid so I'll take a guess at this to possibly help...

Check any covers underneath the dash that may be loose, like the knee airbag for instance. Also, obvious stuff like make sure you have no coins or anything loose in any of the cubby holes in the glove box, console, door pockets, etc.

Good luck

 

I had an issue in my '13 Toyota Avalon. I eliminated the rattle by removing the tray in the glove box. Not sure if this will help, but it is worth a try.

 

^^^ Good one PeteInGilr.

My past IS and CT had a small squeak/rattle because of the tray and how it (plastic tabs) interfaced with the glove-box (other plastic). I tried felt tape (hockey tape) which helped without the heavy manual on it, but I eventually removed the tray and stored the manual in the trunk or out of the car.
