What NHTSA says
Source: Office of Defects Investigation, as filedOn April 18, 2024, the Office of Defects Investigation (ODI) received a Defect Petition (DP) requesting the National Highway Traffic Safety Administration (NHTSA) investigate Nuna Rava child seats for a harness that can allegedly loosen without pressing the harness release button. The Petitioner stated there were 24 complaints in the NHTSA database all describing a similar issue. According to the Petitioner, "this condition has poor detectability and the consequence of failure in case of a crash would be severe or fatal injury". On April 25, 2024, ODI received a second DP requesting NHTSA investigate Nuna child seats for a similar allegation as the initial petition. Upon receiving these petitions, ODI sent an Information Request (IR) letter to Nuna on May 16, 2024, asking for information regarding the petitioners’ allegations. Nuna responded to ODI’s IR letter on June 21, 2024. On July 18, 2024, Nuna submitted a supplemental response to ODI’s IR letter. After evaluating the petitioner’s allegations and Nuna’s responses to ODI’s IR letter, ODI decided to grant the petition and open this defect investigation. On September 18, 2024 ODI opened PE24026 on the 2020-2022 Nuna Rava child seats. These seats had significantly higher failure rates than other model year Nuna Rava child seats analyzed in the DP IR response. Following a meeting with ODI to discuss precedent recalls from peer manufacturers, Nuna filed recall 24C-002 on November 27th, 2024. This recall affected Nuna Rava child seats manufactured from July 16, 2016, to October 25, 2023, which covered the entire scope of PE24026. After submitting this recall, Nuna requested relief from responding to a new IR letter ODI sent on October 24, 2024 for PE24026.ODI granted partial relief but required Nuna to respond to some of the requests. After receiving recall 24C-002 and Nuna’s partial PE24026 IR response, ODI is closing this investigation with recall 24C-002. The Agency reserves the right to take additional action if warranted by future circumstances.

A Preliminary Evaluation is the first formal stage: NHTSA has decided the complaints and other information it screened are worth a closer look, and asks the manufacturer for its own data on the condition. The summary is the agency’s own text from its investigation file, unedited; the opening and closing resumes with the full reasoning are on NHTSA’s site under this number.
What this means for an owner
Source: and what happens nextAn investigation is not a finding that a defect exists, and it puts no duty on anyone. NHTSA opens a Preliminary Evaluation when complaints and other reports suggest a condition worth asking the manufacturer about; it upgrades to an Engineering Analysis when the answers warrant testing; it closes either when it recommends a recall, when the manufacturer recalls on its own, or when no defect trend is found. The agency’s own goals are about four months for a petition, eight for a Preliminary Evaluation or a Recall Query and eighteen for an Engineering Analysis; many run longer.
This one became a recall. The campaign page carries the manufacturer’s filed defect, risk and remedy, the build window and every model year covered; whether one specific vehicle is included is settled by VIN at nhtsa.gov/recalls.

Common questions
Source: NHTSA Office of Defects InvestigationIs PE24026 a recall?
No — it is the investigation that led to one. Recall 24C002000 is the campaign; its page carries the remedy.
Is PE24026 still open?
No. It closed on Apr 22, 2025 and led to recall 24C002000.
Which vehicles does PE24026 cover?
NHTSA opened it on 3 model years: 2020 Nuna Rava CS50, 2021 Nuna Rava CS50, 2022 Nuna Rava CS50. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
