Having issues with a noise when at a stop and letting the brake pedal off, here's a video I'm thinking it might be a rotor or something, car has 33k miles on it. Hoping it's not a engine or transmission mount.

 

I'd just take it to the dealer (I assume you still have warranty time), hard to tell from that clip.

 

Yes I I bought the Infiniti elite warranty so I'll have them check it out, weird thing is that it did right after the car wash, now I don't think it's occurring sound like a clunk, if I hear it again I will take it for a check thank you!

 

if its right after a car wash, I get that too. Once the car dries, the sound goes away. You probably got a wheel wash, so the jets cleaned the crap out of your callipers. This is a lot more apparent the colder it gets too. It happens in my dads q50 as well, and happened in his old ex35.

Id still take it to the dealer, suspicious noise is always a good reason to use your warranty.

 

Yes that's what I was thinking it's better now but it'll still take it and have it checked out soon
