I got stuck yesterday when my AT wouldn't shift out of Park even though the car was on and audio, etc worked. I had to unbuckle grumpy confused toddlers and switch to my wife's Tesla to take them to school. Not fun! When I got home i called customer service and their valet reset method failed so they bumped it up to the next level technician. I got a call within 5 minutes and was told to do a reset specifically "for a certain module" He had me put my foot on the brake and hold down the microphone button AND the Dream Drive buttons on the steering wheel. The cockpit and pilot panels began to slowly gray out and fade and I held the buttons and the brake for 30 seconds. When it rebooted it was fixed!
