Most Reported 2009 Toyota Tacoma Problem Reports
At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.
I got rid of my 2009 Taco because of noise during nonacceleration around 70 mph. I'll be darned if the 2011 doesn't do it also! Come to find out that it is a known problem that they didn't tell me about until I had traded vehicles. It is a serious rattle during times of slack accelerator pedal at higher speeds.
