Q: How much do it cost to replace a occupant restraint controller

If the vehicle has an official recall published, this generally mans that the cost will be covered by the manufacturer by reimbursing the dealer for the cost to fix the issue. This normally means the consumer bears no cost to fix the problem. I would suggest checking with the local dealer to be sure this vehicle does in fact have a recall notice for this and proceed based upon the information they provide relative to the recall.
