What NHTSA says
Source: Office of Defects Investigation, as filedThe Office of Defects Investigation (ODI) received a petition on September 1, 2026 (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. On August 12, 2026, BMW filed Safety Recall 26V525, which addresses the same condition raised in the petition. and covers certain 2022-2026 840i, 840i xDrive, 2021-2023 540i, 540i xDrive, M550i xDrive, and 2024-2026 750e xDrive vehicles. This safety recall addresses potential wear in the connection between the rear driveshaft and rear differential, which could cause the connection to fail. The Vehicle Identification Number included in the petition falls within BMW’s recall scope and subject to BMW’s reimbursement program. Because Safety Recall 26V525 fully addresses the concerns raised in the petition, further investigation is unnecessary. Therefore, ODI is denying this Defect Petition and closing this action. The agency will continue to monitor the remedy and reserves the right to take any action if warranted by future circumstances. To review the ODI reports cited in the Closing Resume ODI report Identification Number document, go to NHTSA.gov.
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 resumes carrying the full reasoning are linked below.

These are NHTSA’s own files, served from the agency’s site — the resumes are what ODI wrote when it opened and closed the action, and the rest is the correspondence behind them, including what the manufacturer sent when the agency asked. They are linked, not copied: where a document names the people who wrote in, that redaction is the agency’s to make and its copy is the one you should read.
What owners had already reported
Source: complaints on file the day it openedWhen NHTSA opened this on Sep 14, 2026, owners had filed 33 complaints with the agency about the model years above, of which 7 named the power train NHTSA went on to investigate. Owner complaints are the agency’s main early signal: ODI screens them, and a Preliminary Evaluation is usually where a pattern in them ends up.
This is what the complaint file held on that date, not a claim about which reports prompted the investigation — NHTSA’s complaint records carry no investigation number, so nobody can make that link from the data alone. The opening resume linked above names the reports ODI itself cited. Complaint records on this site begin with 2016.
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 closed without a recall. That means NHTSA found no defect trend it chose to act on at the time, or the manufacturer addressed the condition another way (a service campaign or a bulletin, which have their own pages). A closed file can be reopened if new reports arrive.

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 closed without one. Whether one particular vehicle has an open recall is a VIN question at nhtsa.gov/recalls.
Is DP26009 still open?
No. It closed on Oct 26, 2026 without a recall.
Which vehicles does DP26009 cover?
NHTSA opened it on 3 model years: 2022 BMW 5 Series, 2021 BMW 5 Series, 2022 BMW 8 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.
