Dashboard Rattling

there are lots of dash rattles threads. search and read for diy or to advise pro. taking it somewhere might be expensive.

 

i've only read to the dealer, but perhaps someone who has taken it elsewhere will chime in. all the best!

 

Check the rear view mirror. Had it happen to me recently, thought it was dash.

 

You will most likely have to add some special tape to tighten the various dash panels.

Mine rattles on the lower part of the drivers triangle window.

 

My 2012 Prius with 80K started having this rattle sound coming from the driver's side dash area. At first, I thought it was the front strut. After taking to a shop to inspect the suspension without results, I talked the dealership into looking at it when I brought it in for an unrelated recall (software update). I don't how I talked them into it as I declined the diagnosis that had a $150 price tag! I half suspect that they didn't even look at and just told me that I needed the steering shafts replaced because they knew about this issue from the previous generation. I took it to yet another shop, that didn't charge a diagnosis fee, but they just said that it's possible I need new shaft(s) and to take it to yet another shop that could do an alignment (it's also pulling to the right) and inspect it more closely! I was about to give up and just have someplace go ahead and replace the damned shafts when I found a post about this issue on here. After a half an hour, I had tightened the bolt on the top of the shaft up behind the steering wheel and the bottom one on the shaft near the floor and the rattling and the shaking was gone! I didn't need to take off the vent or kick panel, only the small black piece that holds the tire sensor stuff and let it hang to access the top bolt and the bottom access was easy as you described. Saved me $980!!
