It's fun vehicle to drive, but I have door locks. First it was the driver side front door lock that is not working. After few months I found out now it's the front passenger side door lock is not working and recently I found that rear passenger side door lock is not working also. I tried dealership to repair it, but due to mileage on it I have to pay $350 for each lock. NO OTHER ISSUES. Does anyone has this problem? Can this be a defective locks from the manufacturer?
