The affected vehicles have been marked with campaign number 0000232600 in AIR.

In order to determine if a specific vehicle is affected by this campaign it will be necessary to verify the vehicle VIN in AIR (Aftersales Information Research). Based on the response of the system, either proceed with the repair or take no further action. Please note, open campaigns or vehicle stops may not appear in DCS Warranty Vehicle Inquiry or sales systems until 24-72 hours after they are announced, therefore AIR is always the recommended method for determining open campaigns and vehicle stops.

 

NHTSA STATEMENT

Please be reminded that it is a violation of federal law (The Safety Act) for you to sell, lease or deliver any new motorcycle covered by this notification until the recall repair has been performed. This means that dealers may not legally deliver new motorcycles to consumers until they are fixed or use/sell replacement equipment/parts subject to this recall. Note also that substantial civil penalties apply to violations of the Safety Act. Also, you should not sell, lease or deliver any used motorcycles subject to a safety recall until the repair is completed. Please follow any special instructions that we provide to you for the return or disposition of recall parts.

 

SITUATION

After close inspection it has been found that in rare cases that riding maneuvers with an abrupt RPM difference between the engine and final drive can result in an overload of the transmission input shaft. As a result the input shaft can break, which can lead to critical riding conditions.

This fault pattern can only occur in the above listed R 1250 models because the software application of the engine control permits significantly higher rev level differences than in the R 1200 models.

 

PROCEDURE

The engine control unit must be updated according to the model-specific repair instructions “61 00 510 – Programming vehicle control units”. The corresponding software (I level K001-22-11-501 or newer) is available at dealer level with ISTA version 4.39.2x.

For vehicles not yet delivered the software update must be completed prior to retail to the customer.

For vehicles already delivered to customers, the Recall must be carried out during the next workshop visit.

Customer letters have been sent to customers with retailed effected motorcycles to arrange a date and time to have the dealer perform the required software update for this Recall.

 

 


BMW R1250GS / GS Adventure / RTP
Gearbox Input Shaft
Part 573 Chronology
January 18, 2023

In October 2020, BMW became aware of a 2019 BMW R1250 GS in Italy in which a customer complained about a broken gearbox input shaft and a blocked rear wheel.  Two additional similar complaints, in Italy and the Netherlands, in October and November 2020, involving 2019 BMW R1250GS models, were received.  An engineering investigation was initiated.

A parts return program was implemented, and the gearbox input shaft supplier was contacted.  Although it was noticed that the three customer complaint motorcycles were all produced in June 2019, a review of the supplier production process did not result in any finding.  Lab analyses involving material property evaluations, x-ray, scanning electron microscope, and surface treatment examinations did not result in any findings.  Initial analyses could not determine a root cause or systematic production anomaly.

In July 2021, a complaint involving a 2019 BMW R1250 GS Adventure in France, about a broken gearbox input shaft (but without a blocked rear wheel), was received.  Further analyses were conducted, including a continuation of the parts return program, and additional supplier production reviews and audits.  Various FMEAs were performed.  Additionally, bench and road tests were conducted, including potential customer misuse riding scenarios.  Further lab tests were performed involving force/torque applications, load change pulsations, x-ray, and dynamometer runs.  The root cause could still not be identified, and the market continued to be monitored.

In June 2022, BMW became aware of an incident involving a 2019 BMW R1250 GS in the United Kingdom that resulted in a crash with injury.  BMW intensified its investigation and analysis process, and in  August 2022, BMW became aware of an incident involving a 2019 R1250 GS in the Czech Republic of a crash without injury.  The analysis activities continued, including a review and comparison of engine, gearbox, and drivetrain design and operating parameters between the R1250 models and the prior generation R1200 models.

The engineering investigation concluded that in certain engine operating and riding conditions, an overload of the gearbox input shaft could occur, and result in damage to, or breakage of, the gearbox input shaft, and possibly result in a blocked rear wheel.

On January 10, 2023, BMW decided to conduct a voluntary safety recall.
