For the past 6 months I've been dealing with an issue that seems to have baffled 2 Toyota dealerships. On any given day, a warning light (red triangle) appears on my dash along with this text on my GPS screen: "The transmission P lock mechanism is abnormal. Park your car at a flat place and apply parking break completely.

If I turn off my car, the car will not go in gear. Last time I brought the car in for service, as soon as it was lifted off of the tow truck. They pushed the start up button, and the car was fine. Unfortunately, that's not always the case, and my fear is that it will happen late at night, when the dealerships are not open.

Has anyone heard of, or had this same issue? Thanks!
