While driving in normal conditions the front end of the car dropped noticeably and began scraping on the ground. The ECS warning lit and the car height could not be adjusted. Upon restart it lifted properly but collapsed again after several miles. The car was parked with the front over the curb so when it collapsed and I attempted to back up it tore the front bumper loose -- another expensive repair on top of the mechanical failure. No reason this part should fail so soon and without warning.
