I just bought a 2011 Avalon base trim in February and have noticed a problem with the driver's seat The main reason that I selected this car was that Consumer Reports rated the driver seat comfort as excellent. I have problems with my back, neck and shoulder and need a very comfortable seat. I now find that there is something like a horizontal piece of pipe that is hitting me in the very lower back and this aggravates my symptoms. The "pipe" feeling goes away some if you put in very high lumbar support, but that also causes problems. I am very disappointed and don't know what to do about this problem.
