My 2011 certified used Toyota highlander AWD has the "whine at 40 mph" and irregular shifting with a “confused and delayed grab” between gears. This issue started around 32,000 miles and was considered "normal" according to Toyota. At 75,000 miles, the transmission has recently developed a shudder in reverse and a downshift to a high RPM when the cruise control is resumed at highway speed. The transmission will not upshift on its own until the driver steps on the brake or manually disables the cruise control. This issue is well documented under service bulletin TSB 0097-13 which involves some dash work and transmission replacement. I brought it to my local Toyota dealer for service. They verified that the transmission is covered up to 100,000 miles under the certified Toyota warranty. However, the service department did not offer any guidance with this issue or service bulletin. They only quoted $640 for diagnostics so I cancelled the appointment. The service department stated that Toyota does not provide free diagnostics and that repairs are part of vehicle ownership. This is not acceptable quality or service that I would expect when purchasing a certified Toyota. I contacted the service manager to give him or her opportunity to provide a better service for this major warranty repair. I have not received a response and will pursue other options if they do not contact me.
