Sad to see you leave but to be honest the self level suspension issue is NOT hard to fix at all...

If you do have an issue with the suspension when you SEE your wheels lowering then simply go to an indy and get your Air bag replaced. If you simply see the error on the cluster when you start the car, the issue that alot of people seem to have...

two ways to fix this.

1: Simply turn the key ALL the way dont "Auto start it" and the error wont show.

Or 2: Get the X's timing sensors adjusted to your proper time.

The issue with the "Auto" start feature in the X is that it tends to start the car up and it doesn't give it enough time to check the suspension senor and therefore you get the error, when its just a timing adjustment.

But anyways that was for others with the same issues, as for you, wish you the best of luck with whatever car you get dude
