Affected Component: POWER TRAIN:AXLE ASSEMBLY

Summary
Some customers may complain of a whining noise from the automatic transaxle when driving at 10 mph and above. The noise:  Depends on the vehicle’s speed only (the more speed, the more noise) Occurs with all types of driving (acceleration, deceleration, steady speed) Does not depend on rpm, gear, or ATF temperature.This is caused by a damaged bearing in the transaxle due to improper configuration of the transaxle case. A modification has now been implemented on automatic transaxles with the following serial numbers:  7TN0820364 and higher (CX-3) / 8TN1090104 and higher (except CX-3)  8TR1008883 and higher  8TD1003276 and higher  8T50331192 and higher (CX-3) / 8T50329705 and higher (except CX-3).
