NHTSA Defect Petition DP24003: Seat harness can loosen without using harness release button on Nuna Rava car seats.
On March 21, 2024, the Office of Defects Investigation (ODI) was sent a defect petition (DP) that requested the National Highway Traffic Safety Administration investigate the NUNA RAVA car seats for a harness that can allegedly loosen without pressing on the harness release button. The Petitioner stated there were 24 complaints in the NHTSA database all detailing the same issue. According to the Petitioner, "this condition has poor detectability (there are no warning lights) and the consequence of failure in case of a crash would be severe or fatal injury". ODI conducted a thorough search of its database and found 32 consumer complaints that were potentially related to the alleged defect. Following the receipt of a second DP mailed on April 1st, ODI sent an Information Request (IR) letter to the manufacturer Nunababy Essentials. The IR letter requested information on NUNA RAVA child seats regarding allegations of a harness loosening without the harness release button being pressed. After reviewing ODI’s internal data and Nuna’s response to the IR letter, ODI decided to grant the petitions and open Preliminary Evaluation PE24-026. This Defect Petition will now be closed due to the opening of the PE. The petitions can be reviewed at NHTSA.gov using the following ODI Report reference numbers: 11583786, 11585272.To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
