What NHTSA says
Source: Office of Defects Investigation, as filedThe Office of Defects Investigation (ODI) received on September 1, 2026 a defect petition dated August 5, 2026, requesting an investigation into an alleged defect in BMW rear differential assemblies. The petitioner alleges Model year (MY) 2022 BMW 540i vehicles are experiencing a sudden mechanical failure that severs the drive connection between the driveshaft and the rear wheels. This defect petition has been opened to evaluate the issue and determine whether to grant or deny the petition. BMW filed Safety Recall 26V525 on August 12, 2026. The petition can be reviewed at NHTSA.gov under ODI number 11761650.
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 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 DP26009 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 DP26009 still open?
Yes, as of NHTSA’s latest file: opened Sep 14, 2026, 6 days ago.
Which vehicles does DP26009 cover?
NHTSA opened it on 1 model year: 2022 BMW 5 Series. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
