Weird Intermittent Rattling Noise
So, have owned Cadillac ATS 3.5 V6 coupe since 2016.
Racked up 300k kms on it.
Love the vehicle, everything runs spectacular. However just have one issue which is now getting really annoying.
There is a intermittent rattling noise when I drive.
At first i thought it was coming from the dash, some bolt was loose. But no! When i lower my windows, i hear the same from outside. I then recorded the sound by keeping my phone on the floor of the car! And there it was! I feel its coming from the centre- bottom area!
It is intermittent so i cant pin point as to what is causing it.
Mechanics over here dont want to put their hand to it as they know it is something which will take alot of time to find but no parts to replace so less profit.
I have added a clip, any help would be appreciated.
