What NHTSA is examining
The agency's own description of the inquiry, quoted as published
Brake Actuator Valve Wear
The Office of Defects Investigation (ODI) has received a petition dated September 19, 2023 from the owner of a 2012 Toyota Prius V requesting that ODI reevaluate its decision to deny DP19-004. In the letter, the petitioner reported experiencing an unexpected and complete loss of brake power while driving, accompanied by multiple dashboard warning lights. This petition is based on the petitioner's direct experience and assessment that ODI closed DP19-004 because its prompting petition was withdrawn by that petitioner. ODI will review the work conducted during DP19-004 and a review of any additional related complaints and crashes via a new defect petition The petition and related materials can be reviewed at NHTSA.gov under the following ODI number:11553736.
An investigation is a separate record from a recall and from a manufacturer communication. A manufacturer campaign to repair a safety defect or a failure to meet a federal safety standard.
