    Do Prius V transmissions fail? Does it cost $6,000 to replace it?

    Polls? Give me a break.

    No (they have almost no failures) and no (maybe $1500 if you can find a salvaged v transaxle NOT a hatchback transaxle AND a good independent hybrid shop ).

    What are the symptoms and issues you had? Not just a dealers report.

    From tech
    80054 CONNECTED THE SCAN TOOL TO THE VEHICLE. PULLED CODE U0110-160 (LOST COMMUNICATION WITH DRIVE MOTOR CONTROL MODULE A). CHECKED THE MODULE A) CONVERTER INVERTER WITH CONVERTER ASSEMBLY (GENERATOR CABLE CONNECTION
    CONDITION). THE BOLTS ARE TORQUED PROPERLY AND THERE ARE NO ARC MARKS FOUND. CHECKED THE CHECK INVERTER WITH CONVERTER ASSEMBLY (MOTOR CABLE CONNECTION CONDITION). THE BOLTS ARE TORQUED PROPERLY AND THERE ARE NO ARC MARKS FOUND. I CHECKED THE HYBRID VEHICLE TRANSMISSION AXLE ASSEMBLY (MG1) WITH A MILLIMETER. THE READINGS ON THE CABLE ARE: PINS
    PINS W-U= 32M OHMS, PINS U-V= 30.9M OHMS, AND PINS V-W= 95.35M OHMS. THE FIRST 2 READINGS ARE OUT OF PARAMETERS SET IN THE REPAIR MANUAL (89.5M OHMS TO 98.9M OHMS). NEXT, I CHECKED THE HYBRID VEHICLE TRANSMISSION NEXT, THE READINGS ON
    AXLE ASSEMBLY (MG2) WITH A MILLIMETER. THE READINGS ON THE CABLE ARE: PINS W-U= 161.7M OHMS, PINS U-V= 21M OHMS, AND PINS V-W= 15M OHMS. THE SECOND 2 READINGS ARE OUT OF PARAMETERS SET IN THE REPAIR MANUAL IN THE (APPROXIMATELY 151.6M OHMS TO 174M OHMS). AT THIS TIME, THE REPAIR MANUAL IS DIRECTING ME TO REPLACE THE HYBRID VEHICLE MOTOR/GENERATOR ASSEMBLY (TRANSMISSION) AND RECHECK OPERATION.

    I might focus on the communication problem which is not in the transaxle. Inverters on gen3s have a history of issues.
