The cost of replacing a StabiliTrak system ranges from $80 to $190, including a labor cost of $30 to $50. However, if StabiliTrak issues result from a destroyed sensor, replacing it becomes necessary. In that case, the cost to install a new sensor is between $250 and $400. If you can't place your hand on the cause for the StabiliTrak Chevy issues, investigate thoroughly and choose an appropriate course of action. If you have never repaired a vehicle, ask the nearest Chevy dealership for an assessment.
