On my 2019 trailhawk with 15000 miles has developed some kind of suspension noise when going over rough road. Can't pin point where it actually comes from and it can be felt and heard. Any experience with this so I can go to the dealer with some knowledge?
Thank you

Possibly a defective strut? Way too early for it to actually wear out.
Make sure the cold tire pressure is 36 PSI.
Have the dealer print a VIP report, maybe there is a TSB?
Can you clamp a GoPro onto something and take movies while driving?
Try pushing and holding the traction control button for several seconds to turn the traction control completely OFF.
Check the Owner's Manual.
Then drive the section of road that causes the suspension noise, does the noise change or go away?
The explanation is too difficult for me to explain.

Find a section of road near the dealership where you can replicate the noise.
Identify exactly the section of road.
Note your speed and direction of travel.
Then the mechanic can duplicate your drive with some expectation of repeating your issue.
Possibly have the mechanic connect the WiTECH and record the front left wheel speed sensor electrical signal.
The mechanic can check for an improper signal trace.
Make sure your mechanic has been to the Chrysler Training Center and knows what he is doing.
