This letter is to inform you of the “ABS Hydraulic Unit Flare Nut Tightening Recall Campaign” for GSX1300RRQM4 and GSX1300RRQ2M4(Hayabusa) produced from Jul. 7, 2023 to Dec. 1, 2023.

We were informed from our production plant that in the piping of the brake system, the tightening torque of the flare nut for fastening the brake pipe to the ABS unit may insufficient due to improper tightening work of the nut. If the motorcycle continues to be used in this condition, in the worst case, the loosening of the nut may cause brake fluid leakage and increase the braking distance.

SAFETY RECALL CAMPAIGN 3A01

2024 Hayabusa ABS Hydraulic Unit Flare Nut Tightening

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act. SuzukieBay logo Motor Corporation has decided that a defect which relates to motor vehicle safety exists in certain 2024 model-year Hayabusa (GSX1300RRM4) and Hayabusa 25th Anniversary Edition (GSX1300RRZM4) motorcycles.

 

What is the defect?

SuzukieBay logo Motor Corporation is initiating a safety recall campaign to tighten the brake fluid pipe flare nuts on the anti-lock brake system module (ABS unit) to the proper torque specification.

The brake fluid pipe flare nut installation torque for the brake fluid supply lines attached at the ABS unit that supply the front and rear brake calipers may have been tightened to less than the correct specification. If the motorcycle continues to be used in this condition, in the worst case, loosening of a flare nut may cause brake fluid leakage and increase braking distance, increasing the risk of a crash.

 

What SuzukieBay logo Motor USA, LLC, will do:

During the week of February 5, 2024, SuzukieBay logo Motor USA, LLC (SMO) will mail notifications to owners of affected Hayabusa motorcycles for whom we have information. The notice instructs the customer to contact a SuzukieBay logo dealer to schedule an appointment for the repair.

If you have sold an affected Hayabusa to a customer prior to receiving this bulletin, please contact the customer immediately to arrange for the motorcycle to be returned to your dealership for this safety recall campaign.

 

Parts are not required for this Safety Recall Campaign:

In normal situations, new parts will not be needed to complete this recall service. If you find parts are required to complete the recall service, contact SuzukieBay logo’s TECH-LINE at (714) 996-7480 or contact your Technical Service & Parts Manager (TSPM) to discuss the situation.

 

 


Chronology of Principal Events

December 13, 2023

SuzukieBay logo Motor Corporation (SuzukieBay logo) received information from its Hamamatsu, Japan manufacturing plant that a quality inspection of the front brake system of a production 2024 Hayabusa (GSX1300R) motorcycle that involved fixed application of the front brake lever to pressurize the front brake system for approximately 4 hours had identified leakage of brake fluid from the anti-lock brake system module (ABS module). The leak area was inspected, and the leak was found to be the result of incompletely tightened brake fluid flare fittings at the ABS module. SuzukieBay logo stopped shipment of all completed 2024 GSX1300R motorcycles and  began an investigation.

 

December 15, 2023

SuzukieBay logo determined that a production line worker who had been responsible for performing attachment of the brake fluid lines to the ABS module had deviated from the normal installation procedure that the worker had been originally instructed to follow. Under the standard procedure as instructed by the worker’s supervisor, the brake fluid flare fitting tightening for 2 specific brake fluid line connections on the output side of ABS module was to be divided into 2 to 3 individual tightening operations due to physical space restrictions around the ABS module that limited the free travel area of the torque wrench. However, the production worker independently altered the tightening procedure to a single wrench movement as opposed to the correct procedure that specified multiple wrench movements. In this condition, it was possible for the torque wrench to make contact with an engine intake pipe during the tightening process, potentially preventing full specified tightening torque to the flare nuts for 2 out of 4 brake fluid line connections to the ABS module.

 

December 22, 2023

SuzukieBay logo inspected the production vehicles from the lot that had been held from shipment and confirmed that some motorcycles had incompletely tightened ABS module brake fluid  flare nut fittings. The flare nut fittings for all held vehicles were inspected and tightened to the correct torque specification and the shipment stop order was removed.

 

December 28, 2023

Following inspection of the 551 GSX1300R motorcycles that had been manufactured and held from shipment, SuzukieBay logo confirmed that the brake piping line flare nuts had been incompletely tightened on some of the vehicles, however no brake fluid leakage was detected on any of the 551 vehicles. SuzukieBay logo determined that the causal fault was the assembly process substitution by the production line worker that had been identified on December 15, 2023.

 

January 18, 2024

Because incomplete tightening of the brake fluid flare nut fittings could allow brake fluid leakage and increased stopping distance in the worst case, SuzukieBay logo decided to perform a safety recall to correct the tightening torque of the ABS module flare nut fittings.
