NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Defect Petition DP25-001.
try.vin does not copy NHTSA's investigation documents; NHTSA's investigation record lists the ones NHTSA has published.
The Office of Defects Investigation (ODI) received a petition on August 22, 2025, requesting a defect investigation into an alleged defect of the “underbody shields” on model year (MY) 2020 Ford Explorer vehicles. The petition alleges premature degradation and detachment of the plastic underbody shields, potentially leading to road debris. The petition itself can be reviewed at NHTSA.gov under ODI number 11682326. A search of the subject vehicle population was undertaken using complaints submitted to ODI. No related complaints were found in NHTSA’s database for the subject vehicle population. Subsequently, ODI conducted a broader search for related complaints and field reports involving MY 2020-2025 Ford Explorer and Lincoln Aviator models, as these vehicles utilize substantially similar underbody shields. No complaints or reports were found citing any allegations pertaining to any of the underbody shields. ODI also reviewed manufacturer information and data and did not identify a trend related to the Petitioner’s allegations. Based on the absence of consumer complaints and reports, ODI has not identified a material risk of a complete detachment or a projectile hazard related to this condition. The petitioner's description of detectable symptoms - including noise and vibration that progressively worsen and visible sagging of the shields underneath the vehicle - indicates a failure mode that provides drivers with ample notice to seek service before a potential detachment. In view of the insufficient evidence of a vehicle-based defect pertaining to the underbody shields of the subject vehicle, ODI is denying this Defect Petition. A Federal Register Notice (FRN) further detailing NHTSA’s reasons for denial of the petition will be published. The Agency reserves the right to take additional action if warranted by future circumstances.

What an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
