Car seat harness in the Nuna RAVA has been difficult to tightening safely and has been loosening after being securely fastened. A manufacturers recall was implemented December 19. Even though my car seat was registered, I have not personally received any correspondence from the company regarding the recall and I have not received the repair kit that is described on the manufacturers recall page. My only option now is continue to use a hazardous car seat or purchase a new one even though my Nuna RAVA is still under the manufacturers warranty. This is dangerous because some families may not be aware of the recall due to the lack of initiative to notify consumers by the company and it has been 3 weeks since the recall and the repair kits still are not available.
