There was no opportunity for failure. however, my husband and i purchased a 2007 subaru outback and neither of our car seats fit safely in the back seat of the vehicle. we have the peg perego infant seat and the britax marathon convertible seat. the sales manager, myself, my husband, and the manufacturer's representative could not get either seat to fit in properly. we had to return the car and purchase the more expensive tribeca. the car seat now fits securely in the back seat. *jb
