My 2012 Acura TL has 120,000 miles on it. I notice the first start of the day or cold start after a few seconds it makes a rattle noise. I have already done these maintenance a couple of months ago a trans flush , new serpentine belt, new battery and spark plugs. I attached a video the noise is at 10 seconds in. Please let me know if anyone knows what part could be causing this noise. Thanks
