Hello, my son got a 2014 LR4 last month and has had no problems with it. Last week it sat in the sloped driveway while we were gone. When we got home, we noticed the front was lowered on both sides. He started it and got a red suspension failure warning. Everything looks normal on the 4x4 screen. We backed it onto flat ground and now all 4 sides are in access height and low to the tires. It will not raise from access height. It seems too low to drive. We are new to land rovers. Any suggestions would be appreciated!
