NHTSA investigation DP19004 is a Defect Petition opened on 2019-09-30 and currently closed. The subject of record is TOYOTA AVALON HYBRID, which places this file inside the Office of Defects Investigation queue for TOYOTA.

A Defect Petition like DP19004 starts when a person or group formally asks NHTSA to investigate a specific alleged defect. Petitioners submit evidence, NHTSA reviews it within 120 days, and either grants the petition (opening a PE) or denies it with a written explanation in the Federal Register.
Investigators summarized the matter as follows: "On September 19, 2019, the Office of Defects Investigation (ODI) received a defect petition from Mr. Roger Hogan requesting that the Agency investigate and recall certain Toyota Prius, Prius PHV, Camry Hybrid and Avalon..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related TOYOTA files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.
Investigation Summary
On September 19, 2019, the Office of Defects Investigation (ODI) received a defect petition from Mr. Roger Hogan requesting that the Agency investigate and recall certain Toyota Prius, Prius PHV, Camry Hybrid and Avalon Hybrid vehicles for a brake actuator valve wear condition covered under Toyota Customer Support Programs ZJB and ZKK (subject CSP’s). In support of his request, the petitioner identified 117 NHTSA complaints allegedly related to the subject CSP condition, including 60 reporting crashes. On September 30, 2019, ODI opened Defect Petition DP19-004 to evaluate the petitioner’s request for an investigation. In August 2020, the petitioner notified the Agency that he was withdrawing his petition. Because the petitioner has withdrawn the petition, we are denying the petition as moot and no further analysis of this petition is necessary. NHTSA is authorized to issue an order requiring notification and remedy of a defect if the Agency’s investigation shows a defect in the design, construction, or performance of a motor vehicle that presents an unreasonable risk to safety. 49 U.S.C. §§ 30102(a)(9), 30118. Because the petitioner has with withdrawn the petition, the petition is denied as moot. This action does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency notes that it is not required to receive a defect petition prior to opening a defect investigation and will take further action if warranted by future circumstances.
