Water got into a double sealed and locked transmission connector, which caused the engine light to come on, and every time I used the accelerator, it jerked hard. The connector had good seals and lock when inspected, but filled with water. The dealer could not figure out how this happened? I should be able to drive in the rain! I have 61,990 miles, and had just finished all my services. I've never had an accident, nor do I drive through rivers.
