The car started yesterday with the Check the Ride Control and No Ride Control on on 1999 Lincoln Continental

The car also feels like bouncing specially when hits a bump, the right air strut is leaking, do I have to change everything or just that specific one. Is this dangerous to drive like this, also the car of course is low in the back

Asked by for the 1999 Lincoln Continental
most likely air bags are leaking.repl as a set or they have aftermarket kit that changes over to regular shock system
Thank you for your help, is there any risks driving like this?

I would replace both rear struts then check for air leaks and make sure the pump is working
Thank you, that is exactly what they told me, Is this dangerous to drive?
