“I drove to work with no problems. However; returning I started car and could hear a slight sound. I immediately noticed that the car rising sign was illuminated and I waited for car to rise. The car failed to rise and was sitting so low to tires that I could not drive and had to be towed home. At home I tried again to see if car would rise and again it failed. In addition to the ABS break sign being illuminated as well. The message on dash stated to contact dealership for service. My mileage is at132,051.”
