I purchased a brand new 2012 Toyota Sequoia. Since I bought the vehicle, the vehicle has had idle/accelerator problems, erratic problems with excessive transmission downshifting, racing, surging, and fluctuation of engine RPM's, making the vehicle difficult to stop safely. When I first purchased the vehicle, the service department explained to me that it was a new vehicle and it needed time, "?one thousand miles, ?? for the engine to break in. Their initial solution to my vehicle'?"S problem did not rectify itself. I have had to return it to the dealership 2 times for repair. They stated that they have confirmed my concerns with the vehicle but it could not be repaired. That it is a design characteristic of the vehicle, that's the way they act, and that it had something to do with fuel-cutting or transmission shifting. He further stated that he forwards his report to Toyota engineers and if there are enough complaints that they will re-write and update the software for the vehicle. Obliviously a safety issue...please advise.
