2008 rattle at highway speeds

No, I haven't heard the rattle ... yet. I have the 2008 Touring model but I only have 10k miles on it. But thank you for telling about the ABS pump. It will be interesting to see what Toyota does about it.

 

I also have a 2008 Touring Pkg #4 and I've got 23,000 miles so far. I drive mostly highway going to and from work, about 34 miles one way. I haven't experienced this rattling yet and I too am annoyed by things like that.

Have you tried calling Toyota and complaining?

 

Have you tried pressing on the dash when the rattle occurs to see if you can get a better location? I have serious doubts about the dealer's story.

 

I to have an 08 prius. i also have this rattle sound that happens. It probably started a couple weeks ago. i have 40k miles on my prius. the noise happens speratcily but usually at speeds over 30 mpg. i have not been to the dealer yet because it is not constant. But it definitively comes from the top left side of the dash and no its not the normal sound the prius makes (capacitor discharge i think it was explained to me when i bought the car). next oil change i will bring it up.

 

it happens every time you go over 65? and is a constant noise?

 

I have one too!! 10K miles and I hear it off and on over 20 mph...but that varies depending on the quality of the road. It is also on the left side and it gets much quieter when I push on the dash next to the air vent. There are photos in another section of the Chat on replacing the radio that shows how to remove the dash, but I am going to a dealer for the next oil change and have them do it under warrenty - with a printout of all these complaints to counter their expected response that this has never happened to anybody else!!!! Unless someone tells me it is very easy to pull off the sections of the dash to see what is loose.

 

The brake accumulator pump noise is a buzzing or rattling sound from under the dash on the drivers side. The sound is intermittent, and usually occurs after the brake pedal has been depressed. It lasts for about two seconds at a time.

A continuous rattle from the dash will be just that: dash rattle. This is fairly common with the Prius and it means you have one or more loose fasteners under the dash. Some people fix this by replacing the fasteners, sometimes they add small pieces of padding. Either way you have to dismantle the dash.

So how do you dismantle the dask??? Is there anything to be downloaded that shows where/how the dash sections come off??
