Consumer Description

There is a known flaw with this car that the transmissions fail prematurely. There is a technical service bulletin (TSB0008-21) released 2 months before purchasing the car on this exact issue and we were not made aware before purchase. Toyota has not recalled these vehicles and this applies to a very select serial number range of transmissions implying a manufacturer defect even further. Now my car, with 68k miles, is expected to have a transmission replaced at full cost. There are many forums discussing this issue and I hope that more people come forward because this is clearly a defect in the design that Toyota should be responsible in fixing.
