Saturday driving on the free at 78 mph, all of a sudden car down shifted, rpms stuck at 2000 and felt like I was in neutral. wrench came up and see manual warning. Powertrain default. Stopped at the next exit turned car off, turned back on no warning, wrench was gone. then ran fine. Came home on the freeway same thing happened. Scary feeling having the kids in the car and if someone was close to me on the freeway they would have rear ended me. Took it to the dealer they couldn't find anyone else that has experienced this but they were going to trouble shoot it.
