Bests & Worsts Reviews from Amazon

Let me start by saying that I was a huge fan of the Evenflo E3 Symphony car seat that we purchased for my daughter on Amazon in 2012, so much so that I purchased another seat (Evenflo Symphony 65 DLX) for my son on Amazon in 2014. The seats always performed well, straps flowed smoothly and the buckles always clicked securely. Then I noticed that the straps were getting harder to tighten. I saw what I thought was some tearing of the harness and I took the seats apart to investigate. To my horror, the Symphony 65 DLX harness was almost completely ripped through! I gave the strap one good strong tug and it completely separated. Attached are pictures depicting the shredded straps. The E3 seat is about 25% ripped through, and I'm uncomfortable to continue using it for our 3rd child. I would like to speak with Evenflo concerning my issues, and determine first and foremost if I should stop using the seat that is still only 25% ripped through (obviously the seat with the totally separated harness is unusable). Also, if there are any recalls or product replacement options available to me. These seats were not cheap; I was willing to pay the premium price because I believed I was getting a premium seat. These harness malfunctions are obviously not what I expected. Parents, I rarely write reviews. I just want to caution you based on my experience. Neither of these seats were used for more than 2 years and they're supposed to last up until 65 pounds!
