I unfortunately learned after purchasing, installing and giving away my infant car seat that this model of Diono's car seat line has a KNOWN DEFECT. I am now left with an unsafe car seat and completely unhelpful Diono customer service. Here are the details: - I had the car seat installed at our children's hospital by a trained technician who has installed hundreds of this model. I brought the seat back a few days later, with my 10 month old in it, to assess a problem I had. The harness straps will tighten and loosen freely without a child in the seat, but are beyond difficult to impossible to tighten to the level safety requires (pinch a quarter inch at collarbone) when child is in the seat. I was told by the hospital that was not normal, that the seat was defective and I should get a new seat. - I called Diono customer service, hoping to be sent a new car seat to switch out the old one with (I have one car, and one car seat, no back up option is available). They told me I needed to uninstall the car seat and send them photos of the harness straps. When I balked at this ridiculous request for a car seat that had been verified as having nothing wrong visibly by a trained car seat technician at the hospital, I was then put on hold while a supervisor was consulted. - Customer service informed me that this car seat has a known defect on some seats where the harness straps don't properly tighten, I was not the first person with this issue, and uninstalling the car seat, replacing the harness straps and reinstalling has resolved this issue for other seat owners. They were going to mail me new straps. When I explained that would leave me to drive my child around in a seat that I didn't feel was safe, they told me overnighting new straps was not an option. Mind you, we're not even sure this will solve the issue, meanwhile, my child is not safe in the car. I am FURIOUS. This company does not care about the safety of its customers' children in any way. How overnighting isn't an option for a KNOWN DEFECT is beyond me. What a terrible company to be in the business of child safety. UPDATE: The children's hospital was so frustrated by the poor customer service I received, for a car seat they recommend to hundreds of parents a year, that they called their sales rep to say how disappointed they were with how my situation was handled. Diono customer service called me and said they were sending me a new seat, but wanted to know that this was NOT their policy, and that they never did this. Great, glad to know you're motivated by money instead of child safety. When the new seat arrived I took it up to the children's hospital and the car seat technicians again set it up and installed. We put my baby in it, and SAME PROBLEM. The hospital told me that the seat should not operate like that, that the tightening of the harness should not be so incredibly difficult, that something was wrong with this seat, as well. The told me to return both Diono seats and to get a different brand, as clearly something was wrong.
