Just a warning to Graco symbio owners. And potential Graco owners The rear wheel has fallen off my symbio and won't stay on.Used it for less than a year. Luckily my child wasn't in it at the time.It started with the sound of a ball bearing loose then the wheel just came off. Have talked to Graco they were no help at all. Just said wheels have 6 month warranty And said sorry they can't help. Appalling customer service. I won't be buying Graco again.
