Chronology :
September 23, 2021
NTN Driveshaft Anderson, Inc. identified a steel ball component issue from a hard to install condition of the joint sub-assembly. Hardness confirmation of steel ball component confirmed insufficiently heat-treated steel balls. NTN Driveshaft Columbus was also notified.
September 27, 2021
Tier-2 supplier of the steel ball component confirmed only specific production lots received abnormal heat-treatment due to improper air/gas mixture and temperature variation from furnace misfires.
September 30, 2021
NTN Driveshaft Anderson, Inc. informed Honda of potentially suspect driveshafts that were shipped to Honda.
These potentially suspect driveshafts were assembled with insufficiently heat-treated steel balls for the front drives shaft outboard joint sub-assembly.
October 4, 202
NTN Driveshaft Columbus informed GM of the potentially suspect Driveshafts shipped to GM plant. These potentially suspect driveshafts were also assembled with insufficiently heat-treated steel balls for the front drives shaft outboard joint sub-assembly.
Mid-October to mid-November, 2021
NTN completed reproduction testing of the potentially suspect parts. After continued use, the steel balls could deform from heat generated by the driveshaft, resulting in outboard joint sub-assembly seizure and driveshaft failure.
November 25, 2021
Honda determined that a defect related to motor vehicle safety existed and decided to conduct a safety recall.
Reference Honda Campaign Number BBY, NBW, OBX
January 20.2022
GM also decided to conduct a safety recall against potentially effected parts established through traceability efforts.
Reference General Motors Campaign Numbers 212351030, N212351031, and N212351032
As of 3/29/22, to the best of our knowledge, Honda and GM has not received any warranty claims, field reports nor reports of crashes or injuries related to this issue.

Chronology :
September 23, 2021
NTN Driveshaft Anderson, Inc. identified a steel ball component issue from a hard to install condition of the
joint sub-assembly. Hardness confirmation of steel ball component confirmed insufficiently heat-treated steel
balls. NTN Driveshaft Columbus was also notified.
September 27, 2021
Tier-2 supplier of the steel ball component confirmed only specific production lots received abnormal heat-treatment
due to improper air/gas mixture and temperature variation from furnace misfires.
September 30, 2021
NTN Driveshaft Anderson, Inc. informed Honda of potentially suspect driveshafts that were shipped to Honda.
These potentially suspect driveshafts were assembled with insufficiently heat-treated steel balls for the front
drives shaft outboard joint sub-assembly.
October 4, 202
NTN Driveshaft Columbus informed GM of the potentially suspect Driveshafts shipped to GM plant. These
potentially suspect driveshafts were also assembled with insufficiently heat-treated steel balls for the front
drives shaft outboard joint sub-assembly.
Mid-October to mid-November, 2021
NTN completed reproduction testing of the potentially suspect parts. After continued use, the steel balls could
deform from heat generated by the driveshaft, resulting in outboard joint sub-assembly seizure and driveshaft
failure.
November 25, 2021
Honda determined that a defect related to motor vehicle safety existed and decided to conduct a safety recall.
Reference Honda Campaign Number BBY, NBW, OBX
January 20.2022
GM also decided to conduct a safety recall against potentially effected parts established through traceability
efforts.
Reference General Motors Campaign Numbers 212351030, N212351031, and N212351032
As of 3/29/22, to the best of our knowledge, Honda and GM has not received any warranty claims, field reports
nor reports of crashes or injuries related to this issue.

Proper heat-treatment of the steel ball component assembled into the
driveshaft component
Identify How/When Recall Condition
was Corrected in Production :
June 4th, 2021
Defect condition- Improper air/gas mixture from soot buildup on air
supply valve caused furnace misfires which led to improper heat-treatment.
June 6th, 2021
Corrected condition- Air/gas mixing valve adjustment to eliminate misfire
of the heat-treat furnace for proper heat treatment and connected
continuous monitoring data logger system for low temperature in heat-treat
furnace.
