Nuna recently issued a voluntary recall for their RAVA car seat, detailed on their website: https://nunababy.com/usa/recalls-rava1
I’ve owned a Nuna RAVA for three years, so I was quick to check whether ours was affected. After securing the seat belt, tightening it, and giving it a pull, I realized there was little resistance—it clearly wasn’t holding tension as it should.
I registered for the recall on Nuna’s site and received confirmation that they’d email me when a cleaning kit becomes available. In the meantime, I decided to investigate the source of the issue myself.
