On Wednesday after exiting the highway and coasting through a turn I attempted to accelerate and the car shook so violently that it felt like I jumped a curb, but it only lasted a second and then it drove fine a couple miles to my house. After I got there I looked under the hood and saw what looked like oil near the trans, so I dropped it off with the dealer and sure enough I get the call the PTU has failed internally, but no news as to what would have caused it.
Just hit 22,000 miles on it to. Hopefully they check and see if it caused any damage to the trans when it locked up like that
