High pitch whistling noise in 2012?

Just drove my new double cab 2012 Taco off the lot Wed evening. Heard the whistling Thurs on the way to friends for Thanksgiving dinner. Starts at 30-35 mph, becomes a higher pitch as you continue to accelerate. Brought the vehicle back Fri, they adjusted the seal inside the hood, noise appeared to be gone...no luck it is back...now it is intermittent and at a different pitch.
Any ideas? Appreciate the comments.

 

I've got it too, but I've yet to narrow it down. Don't think it's the same whistle as the windshield TSB. The search continues.

 

someone posted about this a little while ago... not sure which thread it was in. he ended up taping off a bunch of stuff and slowly taking bits off and he narrowed his whistle down to a section of the grille/hood or grille/bumper alignment... try searching through the threads from the past week or two.

 

Looks like you paid extra for the whistler package.

As stated start taping off seams on the front of the truck. More than likely it will be the seal/mouldings that go around the windshield.

Pin point it and then take it to the dealer for the TSB. They just mask over the problem pretty much since they are cheap.

 

Here's the other thread where the guy narrowed it down to the grille.

Went to another dealership on Thurs...they fixed it! They isolated the high pitch whistle to the long rubber seal inside the hood, above the grill....basically open your hood and look down. You will see the long blk rubber seal running almost the length of the grill inside the hood. They said it was "soft" rubber and it was vibrating at faster speeds (starting around 40 mph) so they ran a hard plastic dowal rod through the entire rubber seal. NO whistle now and I have put about 100 miles on the truck since the fix....way to go Toyota of Jacksonville, NC - GREAT work!

 

Dowel diameter?

 

I'll check the paperwork. You can see it is a snug fit.

 

this noise seems to be a widespread problem in the 2012 taco. we like others had taped off the front end, hood seams and just about everything else to locate the problem and we could always eliminate the noise by taping the center hood over the weather strip--looks great to ride around in a new red taco with green tape on the hood! last week i got on site and found a few solutions, such as a 1/4" drain line or copper tubing inserted in the weather stripping center of hood above grill. my weather stipping was replaced by the dealership (which only changed the high pitched noise from 1 annoying high pitch sound to 3) the strip has 2 openings that i was able to insert a 7/64" drain line through the top hole and this has completely gotten rid of the noise--been a week now. point is, you just have to beef up the strip to seal the gap between the hood and the grill. here are some pics, hope it is helpful. very happy noise free taco owner signing out.

 

brand new 2012 dc lb... drove it over 1300kms in 48 hrs...
diving west today directly into High winds at approx 115-125km/h yields a loud whistle noise that can be heard - sound like it comes from near the passenger side windshield wiper...
maybe could be up near rear view mirror? maybe low on the window seal/joint...
I took video of it.. will try to post it.

 

Just drove if 500 miles today and discovered this fivking whistle. I swear it's the antenna. Only at 75-80mph driving in a headwind.

 

Why it is the TRD factory installed deer whistle for the 2013 Tacoma that is being tested on the 2012.

I am sorry that so many have this problem, the dowel material that they are used may be the plastic round stock that is used to fill gaps before you apply caulking. If you want to DIY, you can get it at the hardware store. I don't know what size that works on the whistling rubber strip.

 

Fixed mine yesterday (after reading TW forums) for 42 cents. I happened to be at OSH buying plants and saw 1/4 inch outside diameter clear poly tubing for 13 cents/foot. This tubing seemed more rigid than others, lubricated end and threaded through.

 

I just took my first trip in my fully decked out 2012 ToyotaTacoma TRD. I went from LA to Las Vegas. As soon as I hit 70+ mph I got this noise. It stayed with me for 4 hours there and 4 hours back. I could not turn the radio up high enough to cover this up and I could not use on Bluetooth system because the noise was so loud. I was ready to set my truck on fire after 8 hours of this. I showed this to the dealer and they are going to try and figure it out next week. Wish me luck.

Thats the cuzoo sound!!! Its your windshield molding, if you're below 30k miles, just take it to the dealership, they'll fix it. Suprised to see it on a 2k12 though. Same exact sound I had to listen to for awhile... annoying!

 

Just picked up my new 2013 Taco from dealership and began hearing the wind noise on the way home. I followed the posted advice about stuffing the weather strip between the hood and grill with tubing and the noise is gone-- without having to return to the dealer! Thanks for the tip.

 

Subbed I have the sound too.

 

My new 2013 had the noise. I inserted 31.25" of 1/4" poly tubing into the top opening of the hood gasket that is on top of the grille. The noise is gone. I had to put some WD-40 on the insert end to get it through. This cost me $0.52 at Lowe's.

 

Shoot, my new 2005 has this too. Every once in a while though. Thank goodness not for 8 hours.

 

Thanks all for this simple solution! I just leased a 2013 PreRunner SR5 and immediately noticed the noise (only around 40-65mph)

Bought the 1/4" plastic drain (tubing) from Home Depot for $2.50 and this was resolved. Glad I found it on here before going back to stealership.

WD40 helped a ton as well.

Cheers!
