Complaint Summary
POWER TRAIN
Owner Narrative
The car started making whining noises when pressing the gas pedal. Toyota reported "noise from transaxle final drive. recommend replace. vehicle ok to drive but noise will continue until transaxle is replaced." There are no warning lights, messages or other symptoms prior to the sound starting or currently. This is a known issue with its 8-speed automatic transmission (UA80E/UA80F) that can cause whining, erratic shifting, and premature failure. This issue is the subject of a Customer Support Program (CSP ZJC) and several lawsuits, but the program has limited coverage for VINs, leading to owner complaints about a lack of assistance from Toyota.
