My Rava car seat was recalled voluntarily due to an issue with the harness tether loosening from debris getting into the latch secondary to a manufacturer design flaw. When replacing my car seat cover as per the recall instructions, I discovered the impact foam on my Rava was completely cracked down the middle. The car seat has never been moved out of my vehicle since the initial install other than to replace the cover as per recall instructions, and my car along with the car seat have never been in an accident. I only discovered the cracked impact foam because I was replacing the car seat cover as per the recall instructions. I have no idea how long the car seat had been compromised like this as I have never had to remove the cover for any reason. I contacted Nuna about this issue and they stated since it is out of the 2 year warranty they cant do anything about it and to discontinue use. I am now out the $600 I spent on a car seat that allegedly had stellar safety ratings. There are hundreds of people on online forums complaining about the same issue with Nunas impact foam. Had I not discovered this malfunction my daughter could have been seriously injured in the event of a crash. This is a huge safety issue and should be addressed with the company. I do have photos I can send in a separate email, however, will not upload on this web forum.
