If you continue to use it, give the harness a sharp tug before buckling it up, to make sure it's still on the splitter plate. DH was trying to untwist the straps as they got twisted when DS climbed in/out, and as DH was fiddling with them, one harness strap came off the splitter plate and ended up in his hands. To fix, you have to install and attach it back up. They just slip really easily off the splitter plate.
My annoyance is that I contacted them 2 weeks ago. Why did they send me a 2nd seat that's also affected by the recall. Didn't they know it was seats before Dec 2007, so then send me one with a DOM after Dec. Or, tell me to hold on a couple of weeks for a fix. I do think it's the right hand not knowing what the left hand is doing. But now I have to sort out with them what to do about the new seat they sent.
