I have your answer. I had the very same problem on my 2007 xc70. Its the bracket holding the muffler...it vibrates in the rain/moisture and creates that scary high pitched noise. When I called Big Dee Volvo...they knew all about it and fixed it (replaced bracket) for me free as part of the normal (very expensive) servicing. Problem was solved.

Unbelievable! This just happened to me yesterday driving through a torrential rain storm in Connecticut. (2004 XC70). In addition to 3 screaming kids and pounding rain, this siren sound started. It seemed to go away slightly if I sped up, too.
The dealer we called hadn't heard of this problem but I'll try again. Thanks for the info.

I had a similar experience with my car. I had driven over a rasied manhole cover and the exhaust pipe was bent (but functioned properly). The dealership tried their best to straighten it out but it would have been quite expensive to change it out. I decided to drive as is. I simply laughed every time it rained and said "Singing in the rain..." Did get interesting looks from other drivers.

Happens all of the time when I drive in snow and slush. I have a roof rack...does anyone else? It is a combination of wind, snow build-up, and speed. I also have a Thule box on top, maybe it adds to the problem. It only happens at specific wind angles and wetness levels. That is the cause of my noise and may be for some of you.
#15 of 20 XC70 Loud siren like noise in the rain

I have a XC70 with 100,000 miles and recently it began making a loud siren like noise in heavy rain, usually not over 60 mph. My local dealer mentioned something about the drive shaft hitting the muffler but I checked and there is no evidence. I noted the kit below. Does it resolve the problem?
#16 of 20 Rain = whistling

I've seen 2 or 3 analyses here, and wonder what the final conclusion is. Neither the dealer nor any of the local Volvo specialists have heard of this problem! I find that very odd since several of you all have experienced it as do I.
Someone mentioned a "kit" that fixes the problem, and another popular cure here has to do with a muffler bracket. Are they the same fix?
It's heading towards the rainy season here in Seattle, and I'd love to find a remedy before it gets really wet out there.

I have a new to me '06 xc70, driven in heavy rain over summer, no issues. Today, w/ our 1 st heavy wet snow in NJ, I got what I believe is the same noise. I thought it was binding brakes. Only happened at above 30 mph, not below. Can this be the same thing? If so, what is the part # or name for kit described as the "fix"? TIA

I still haven't found a solution to the whistling noise. It isn't drive shaft or brakes. It only happens after driving through water or slush. No vibration, no change in pitch or difference when changing speed. My guess is that whenever the water is dispersed, the sound ends. Local mechanics haven't heard of the issue before, including the dealer. They all want to hear it, which of course is difficult since it only happens in very wet conditions. My mechanic wonders if it is vacuum related.

In a torrential rain storm tonite on the freeway and heard this horrific noise coming from the engine compartment. Came on....subsided some.....then back on full. Pulled off at nearest exit. Drove at 30 MPH for a minute....it faintly came back and stayed away for entire 25 minute drive home at city street speed.
Got home, google'd "high pitch noise 2007 Volvo XC70" and this immediately popped up. If there's a fix--i.e., muffler bracket--I want it, because if my wife or kids were driving, they would have FREAKED.
#20 of 20 Supposed cure never revealed

The person who posted about the "kit" cure has never responded to any inquiries about it. My local dealer and Volvo specialty shops maintain they've never heard of the issue before. I find it hard to believe since Seattle seems to be Volvo Central.. They're everywhere!
It's rare for me to hear the sound these days, but every once in a while, after I've been surfing through slush or BIG puddles, it returns.
