I know the Lib has a slight a sag on the driver side especially with a full tank of gas it's not a few inches though. First thing just before you bring to the dealership make sure you have proper inflation in the tires, check your lean in a few different garages or spots maybe use a friend or significant other's car as a control and park your Lib the same exact in the same spot. Still see a difference make a note of it a picture with a tape measure showing the sag as reference and bring it to the dealer. Just wondering too, how does it drive?
Eventually, if you decide to keep your Lib past it's warranty you could go aftermarket, there are plenty of posts on this forum about that. Feel free to review.
When you get knee-deep in a situation, floor it.
