2018 BMW K1600B

On 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.

I own a 2018 BMW K1600B motorcycle. At highway speeds above approximately 65 mph, the rear of the motorcycle feels unstable and moves side to side, creating an unsafe riding condition. The motorcycle does not feel planted on the road and requires constant rider correction to maintain a straight path. I have verified tire pressures are correct and have tested different suspension settings, rider and luggage preload settings, windshield positions, and riding modes including Dynamic mode. The condition remains present regardless of these adjustments. The instability becomes more noticeable at higher highway speeds and creates a feeling that the rear of the motorcycle is moving away from the rider. This affects rider confidence and appears to be a potential safety issue because it can make the motorcycle difficult to control. I am submitting this complaint because the condition appears abnormal and may be related to known stability concerns reported by other owners of similar BMW K1600 motorcycles.

The contact owns a 2018 BMW K-1600 B Motorcycle. The contact stated that the fuel pump was leaking. The motorcycle was taken to an independent mechanic who determined that the failure was related to the fuel pump. The contact associated the failure with NHTSA Campaign Number: 21V060000 (Fuel System, Gasoline). The local dealer was contacted, who confirmed there was no open recall associated with the VIN. The motorcycle was not diagnosed or repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline for assistance. The approximate failure mileage was 8,600.

2018 BMW K1600** To whom it may concern My name is [XXX] and I am filing a safety complaint regarding my 2018 BMW K1600 motorcycle VIN [XXX] . My motorcycle has a serious and dangerous stability problem that happens at normal highway speeds. While riding at about sixty miles per hour and higher the motorcycle begins to wobble and feel unstable. The front end becomes light and the handlebars feel like they want to move on their own. The back of the motorcycle moves from side to side as if the rear is shifting under me. At times it feels like the bike is sliding or going out from underneath me even though the road is straight and smooth. This is a very unsafe feeling and it can happen at any time on the highway. This instability becomes worse when passing large trucks or riding in crosswind. The movement is not caused by rider input. The bike has correct tire pressure and has no suspension or frame modifications. This issue appears linked to the design or mechanical components of the motorcycle. The wobble is strong enough that it feels like a loss of control could happen without warning. This puts the rider at risk of a serious accident or injury. I am aware that similar complaints have been reported by many other BMW K1600 owners in these model years and that NHTSA has previously reviewed this issue. I respectfully request that NHTSA reopen and fully investigate this wobble and stability problem for the 2018 BMW K1600 motorcycle line and determine whether a recall or corrective action is needed to ensure rider safety. Thank you for your attention to this serious matter. Respectfully submitted [XXX] Orlando Florida VIN [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When I drive my motorcycle on the highway with 70 mph +/- 5 miles, the bike is unstable, the steering bar is shaking, and it is hard to keep the bike in the lane. I complained to the dealer, they balanced the wheel, tested the bike, but the problem has not been solved.

The motorcycle (BMW K1600 Grand America) goes into "Limp Mode" with the engine warning light where the motorcycle has no power until stopped, shutdown, and restarted. This happened to my motorcycle 4 times. Each time the BMW service cannot find any indication stored in the onboard computer. Also, there have been many reported issues of this in the BMW motorcycle forums. This issue is extremely dangerous because the last time this issue occurred, I was on a highway traveling at 70MPH in the left lane and suddenly lost power. Another time this occurred was during rush hour traffic. Both occurrences are very troubling.

THE MOTORCYCLE WILL RANDOMLY GO INTO WHAT BMW CALLS "LIMP MODE" AND THE OPERATOR WILL LOSE ALL THROTTLE CONTROL. POTENTIALLY FATAL IF IT HAPPENS IN CERTAIN CIRCUMSTANCES LIKE HEAVY TRAFFIC ON AN INTERSTATE, AT NIGHT WITH NOWHERE TO PULL OVER LIKE IT DID WITH ME. THIS HA HAPPENED TWICE SO FAR WITH NO FIX IN SIGHT

The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle “discharged battery” complaints.

Due to a hardware change to the angular rate sensor, certain sub functions will not be active until after a software update.

Due to a hardware change to the angular rate sensor, a specific function "Front Wheel Lift Detection" of the Pro Driving Modes is not activated.

Coolant is leaking from under the car which is equipped with the N63 engine. A low coolant warning might also be displayed (CC Message ID166).

Emission Control Information.?

When diagnosing fault codes (0x3A13D7, 0x3A13D9), technicians erroneously condemn the electronic throttle grip, which analyses show is rarely the culprit.
