An older LS 430 may develop uneven ride height, electrical issues or suspension noise depending on equipment and age.
How the concern should be evaluated
Verify whether air suspension is installed, inspect height behavior and leaks, and test electrical power and grounds before replacing modules.
When to contact a Lexus repair shop
If you notice an abnormal sound, warning light, fluid leak or drivability change, call Mich’s Foreign Cars with the year, exact model, powertrain, symptom history and any previous repairs. Service availability depends on the system and required equipment.
