Easy but not inexpensive! Mine just busted and looking at new parts it's over $500. I'm hoping my extended warranty will cover the dealership fixing it, though.

Add another one 2012 . Did it three times, first went away on it's own without stopping, second went away after a full 5 min+ stop and third went away after a ~3 min stop ( no door opening)
Brought it to the dealer after the first two and they reset computer and transmission. 115 miles later it happened again and they have it now.
No messages or warning lights and the dealer said no codes were thrown.

Looking at one to buy. Was warned limp mode, forgot my scanner at home, CEL is on. Drove it 20k, returned it. Was idling, then somewhat slowly stalled in Park!! Restarted it, ran even smoother than before! Will scan it properly tomorrow, local car.
