lately I been noticing a small chirping noise when I turn off my Lexus IS sport 2016. Is this normal ?? It's kinda like a bird chirping right when the egnition turns off. It doesn't happen all the time, but it happens. I just want to make sure if issue is normal or not. Accordingly to the dealer it's a normal noise?????

 

I am not sure without hearing the noise myself, but it could be the vapor pump. My IS350 makes a noise every now and then while its off and that is what it is. My wife kept asking me about it until I told her "that's the sex appeal evaporating so all these young hotties don't try to take your man". She called me an idiot and never mentioned it again

 

Possibly the same issue as in this thread... https://www.clublexus.com/forums/is-...rt-2016-a.html
