BMW engineering analysis EA19003
Steering Oscillation. NHTSA’s Office of Defects Investigation opened this engineering analysis about the steering on 2 model years (2018–2019). Opened Oct 11, 2019, closed Jan 16, 2025 after 5.3 years without a recall. closed
What NHTSA says
Source: Office of Defects Investigation, as filedOn October 11, 2019, the Office of Defects Investigation (ODI) opened Engineering Analysis (EA) 19003 to investigate reports of steering oscillations in model year (MY) 2018-19 BMW K1600 motorcycles. Complainants alleged steering oscillations (wobble and shake) and instability while traveling at highway speeds that were exacerbated while riding in traffic. ODI opened the EA, upgrading its PE19002 investigation, to evaluate the severity and frequency associated with the alleged defect and potential testing options. ODI sent an Information Request containing several technical questions about testing and simulation that BMW conducted during development and production of the subject vehicles. BMW provided responsive details that were reviewed and analyzed by engineers both in ODI and at NHTSA's Vehicle Research and Test Center (VRTC). BMW provided documentation that confirmed that during the design phase, it had conducted extensive testing and simulations to evaluate and quantify the aerodynamic (wind) loads and overall stability. BMW continues to research aerodynamic improvements that can help reduce effects from turbulent air. In the meantime, to mitigate undesirable effects from aerodynamic loads and other vehicle dynamic forces at excessively high speed, BMW limited the K1600 Grand America variant to approximately 100mph. All produced vehicles of this variant have this speed limitation.Recently, a peer motorcycle was recalled under NHTSA recall number 23V836 for high-speed stability concerns. Like BMW's design for the K1600 Grand America, the recall remedy involved applying a speed restriction. VRTC, in coordination with ODI, mailed out questionnaires to 98 owners of K1600 motorcycles in the State of Ohio. Questions relevant to the investigation included: time of ownership, accumulated mileage, how owners handled potential issues, service received for potential issues, and any crashes of the subject vehicles. VRTC received 44 responses to the questionnaires from owners of the subject vehicles. Of the 44 questionnaire responses, 10 owners responded that they had experienced some form of motorcycle instability, which was relevant to this EA. Of those 10 owners, all were able to safely adjust to the instability without a vehicle crash or injury. At this time, no crashes or injuries have been associated with allegations of steering oscillation or instability. This includes 24 complaints that relate to this issue in MY 2018-19 BMW K1600 motorcycles, which ODI reviewed during NHTSA’s PE19002 and EA19003 investigations. ODI also reviewed complaints about the subject vehicles, which BMW provided to ODI in the form of Field Reports, Consumer Complaints, and Warranty Claims. ODI reviewed a combined 41 unique complaints (removing duplicate complaints) that alleged instability, and none of the complainants indicated an associated vehicle crash or injury. The oscillation occurs during high highway speed (well beyond any US-speed limit), and NHTSA received reports that the operators can adjust their speed to regain full control of their motorcycles without a known crash or injury.Based on the available information, NHTSA is closing this investigation without further action. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency reserves the right to take additional action if warranted by future circumstances.

A Engineering Analysis is the deeper stage, usually upgraded from a Preliminary Evaluation: NHTSA tests, requests engineering documents and decides whether a safety defect exists. 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 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 EA19003 a recall?
No. A engineering analysis 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 EA19003 still open?
No. It closed on Jan 16, 2025 without a recall.
Which vehicles does EA19003 cover?
NHTSA opened it on 2 model years: 2018 BMW K1600B, 2019 BMW K1600B. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
