High pitch whistle noise at 45+ mph - 2018

https://www.tacomaworld.com/threads/solved-howling-noise-between-35-45.410480/

 

I have a pin sized hole in the plastic inner tire well. I assumed mine was coming from that. If the sun is shining perfectly, I can see light.

 

I read through that thread and was 1. Under the impression that 2018's come with the plugs installed and 2. That isn't the noise I am hearing

 

then the only other whistle is

1. the side mirrors
2. a/c whistle

from what I remember off the top of my head.

there are old threads about those also.

 

Thanks for the link - love the Ocarina reference there. Time to crawl under the truck and take a look!

 

My forum searching skills are failing me, if anyone has links to these that would be great

 

Check your exhaust and tighten the flanges.

as a side note, my 2018 tundra has the a/c whistle depending on fan speed and if I have any vents closed out. think its related to the round vents, I don't have this issue in my squarish vents on my 4runner.

 

Could this be the notorious door seal problem that 2nd Gen's had a TSB for? LOL

Toyota is well known for not fixing shit.

 

I had this for the first thousand or two thousand miles(was also cold then). I havent heard it lately.

 

Update: Checked and my LCA has the plug fix installed already so its not that. Its also definitely not the AC. Additionally, since I started checking these forums I read about the vibration issue with the hood, went and looked and mine is fully disbonded. Already regretting getting this thing.

 

I thought it was my intake... seems to come on around 45mph usually when accelamerating.

 

happens even cruising

 

update for those interested: Went to dealership, dropped it off and told them the problem (as well as showed them the hood problem). Just got a call saying that they replaced the drivers side door seal and it fixed my issue, going to pick it up soon so hopefully it will be all good!

 

Glad you got it fixed!

 

What did they say about the hood problem?

 

Originally when I dropped the truck off, I told them the hood vibrates and that there is clear disbonding of the hood from its support. When I came back, they had edited my quote to say I had claimed it was rattling (very different than vibrating...) and said they did not hear any rattling. They also claimed that the hoods condition was standard and consistent with all other trucks on the lot.

I clarified with them that I don't really care if every truck on the lot they sell has a disbonded hood issue, my problem is that MY truck has the issue. I had them bring out the head technician and agreed with me once he took a look at it, so now I am going back on monday to drop it off and have it sent to a body shop

 

What is this issue?? Link?
