The Office of Defects Investigation (ODI) of the National Highway Traffic Safety Administration (NHTSA) received a petition dated June 7, 2023, along with several subsequent submissions from the petitioner, requesting an investigation of the vehicle CAN Bus vulnerability to external attack in the Model Year (MY) 2019 Toyota Yaris. The petitioner described multiple electrical symptoms including but limited to: multiple electrical instrument panel warning lights, inaccurate fuel gauge, inoperative key fob, no-start since late 2022, and enclosed references to cybersecurity articles and websites. This defect petition has been opened to evaluate the allegation and determine whether to grant or deny the petitioner's request. The petition can be reviewed at NHTSA.gov under reference ODI number 11501206.

A Defect Petition is a petition from a member of the public asking NHTSA to open a defect investigation; the agency grants or denies it and publishes the reasons. 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 next

An 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 is open. Nothing is owed on the vehicle today; if it becomes a recall, owners are written to and the repair is free. The moment to know is the day the campaign number appears — Recall Watch checks each VIN against every new NHTSA campaign and emails you when one lands, or take a free one-line alert by model year.

Common questions

Source: NHTSA Office of Defects Investigation

Is DP23004 a recall?

No. A defect petition is NHTSA asking questions, not a recall. A safety recall carries an NHTSA campaign number and a duty to repair for free; this one has not produced one. Whether one particular vehicle has an open recall is a VIN question at nhtsa.gov/recalls.

Is DP23004 still open?

Yes, as of NHTSA’s latest file: opened Aug 30, 2023, 3.1 years ago.

Which vehicles does DP23004 cover?

NHTSA opened it on 1 model year: 2019 Toyota Yaris. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
