Component: Power Train / Automatic Transmission (UA80F 8-speed).  The vehicle has developed a pronounced whining noise from the transmission that rises with road speed, accompanied by harsh/rough shifting. A Toyota dealer inspected the vehicle and diagnosed a failing transmission requiring replacement. The symptoms and diagnostic trouble codes match those described in Toyota TSB T-SB-0160-18 (\"Transaxle Whine Noise, Harsh Shift, MIL ON, or Reduced Power\") for the UA80 8-speed transmission.  This is the same failure mode Toyota acknowledged in Customer Support Program ZJC, which attributes the defect to a washer/locking tab that was not sufficiently bent during assembly, allowing an internal nut to loosen and causing progressive internal damage. However, this vehicle's transaxle serial number falls outside the range covered by ZJC, so Toyota has not provided coverage despite the identical defect and symptoms.  This represents a safety concern. Based on documented failures of this transmission across the UA80 platform, the condition can progress to loss of power, limp mode, or sudden loss of forward propulsion while driving \u2014 including at highway speed and without further warning \u2014 creating a risk of a crash or of being stranded in traffic. The vehicle has been maintained through authorized Toyota service.  I am requesting that NHTSA investigate whether the UA80/UA80F transmission defect warrants a broader safety defect determination and recall, given the volume of similar complaints across affected model years  INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)","products":[{"type":"Vehicle","productYear":"2018","productMake":"TOYOTA","productModel":"SIENNA","manufacturer":"Toyota Motor Corporation"}]}]}
