Engine noise please help!!

I have a 2018 tacoma this is my first truck i got it for work purposes mostly. I love this truck toyota makes an amazing product i plan on having it for a long time and taking care of it well.

That being said theres a sound when i turn the engine off its like w quick hissing or grinding. They said it was the evap systen and all 3rd gens have it. Can annyone confirm that? Its only when i turn the engine off. Happens everytime but i didnt notice it at first.

 

I also own an 18 taco access cab and i hear it every time. I was told it was normal.

 

Normal

 

My engine only makes a noise when I turn it on.

 

Probably the same thing 2012-2015 models have. There's a stupid government regulated pump that pushes air into our exhaust system.

Hisses when you shut the truck off.

 

Welcome to the forum Jay.
As stated above this is normal.

 

Maybe it's my hearing. They say that as you age, you slowly lose the ability to hear higher pitched tones.

 

I hear a hiss from my 1st gen after shut down. Crack the gas cap and it goes away.

 

Thats what they said it was at the dealer i just dont remember hearing it at first. Had to get some confirmation. Thanks.

 

Not just tacoma our vw makes simular sound too

 

Its Normal...

and Welcome!

 

NORMAL
