I bought 2009 Subarba LTZ milage 103K. It show a message that Service suspension system. When I run the car at normal speed or high speed and pass over small bumps or or uneven roads the car vibrates especially steering. It vibrates on bumps and uneven roads. It goes smooth on the smooth roads. Can anybody tells me wgat could be the possible reason. I showed it to one of the mechanic and he said that the front left strut in NOT GOOD. Can somebody experienced this situation. Apprciate your replies.

This may be caused by the wiring to the automatic level control pressure sensor being shorted to the ground. This is just a suggestion, not a diagnosis.

I encourage you to consult with a certified technician for additional assistance. They should be able to offer you a more accurate diagnosis, and repair options, after physically inspecting the vehicle.
