Still in the shop. They don't believe that it is the Automatic Transmission Fluid Warmer Connector. Couldn't find any coolant leaks. They have been in contact with Kia and have replaced the high speed fuel pump. They also took fuel samples to send to Kia. I had mentioned that my turn signal didn't always cancel, especially after a left turn. They checked, but didn't find a problem. However, when I checked the status of my car yesterday they had ordered and installed a new turn signal module. Found that in fact the left signal did not always cancel. Want to carefully check everything before they return the car. They did give me a new Nissan Rouge as a loaner. Think that I should be getting my Stinger back today. Am impressed that they are being very careful to make sure everything is working well. Will keep you posted.
