Rivian preliminary evaluation PE26004
Rear Toe Link May Separate. NHTSA’s Office of Defects Investigation opened this preliminary evaluation about the rear on 8 model years (2022–2025). Opened May 26, 2026 and still open — 4 months so far, against NHTSA’s goal of eight months for a preliminary evaluation. open
What NHTSA says
Source: Office of Defects Investigation, as filedThe Office of Defects Investigation (ODI) has received two Vehicle Owner Questionnaires (VOQs) reporting left rear toe link separation in certain Model Year (MY) 2023-2024 Rivian R1S vehicles. Both VOQs report component separation while driving, causing the vehicles to swerve across multiple lanes of traffic. One incident resulted in a collision with an adjacent vehicle and roadside barrier. In both separations, the bolt that maintains the integrity of the toe link fractured. Evidence collected from the complaint vehicles included repair histories, onboard video, imagery of the damaged components, and a police accident report. The two vehicles with reported separation have different vehicle histories. One vehicle received prior service and the other was involved in a previous collision. In both instances, the vehicles operated for multiple months and thousands of miles of usage with no apparent problems between the previous service or the previous collision and the failures that prompted this investigation. Rivian recognized the subject toe link joint’s sensitivity to service procedures in March of 2025 in its updated service procedures. In January 2026 through recall 26V-003, Rivian extended the improved repair procedure to vehicles that received toe link service prior to the March 2025 improvement. ODI is opening a Preliminary Evaluation (PE) to (1) assess the sensitivity of the rear toe link joint to foreseeable road and service conditions, (2) compare the physical failure evidence from the two VOQs to identify apparent similarities and potential differences, (3) evaluate Rivian’s current toe link repair procedure, and (4) assess the in-field subject population’s toe links conditions.

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 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 InvestigationIs PE26004 a recall?
No. A preliminary evaluation 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 PE26004 still open?
Yes, as of NHTSA’s latest file: opened May 26, 2026, 4 months ago.
Which vehicles does PE26004 cover?
NHTSA opened it on 8 model years: 2025 Rivian R1S, 2024 Rivian R1S, 2023 Rivian R1S, 2022 Rivian R1S, 2025 Rivian R1T, 2024 Rivian R1T and more. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
