Car fails to start. We had this car towed to a dealer 40 miles away from our daughter's school in mi. Needs new key system as chip not recognized and ignition system needs to be re-keyed. 8 keys have been issued to this car,(we bought it used). We only received 1 with our purchase! everything that needs a key has to be changed. Cost estimated at $4000. We see this as a major design flaw, not a security benefit. Especiallly since their keys just quit working.
