Since your unit is new and under warranty best to have service dept have a look...But you can do a hydraulic purge yourself before towing back to dealership to see if it’s just air in the system..

Since you are not seeing external leak then either you Have air in the system or an internal bypass leak on one of the two front LG..

There is only one solenoid valve for FLG mounted on passenger FLG side..the FLG is a “lead and follower” system..

Here is how to purge your hydraulic system of air.....
