drdiesel, thanks for your input. You're right, I will find out if they fixed it lol. It's been a day since I got the car back and the code hasn't appeared yet, but I have done very little driving with the gas engine. I will come back and let you know if the code reappears. It might be awhile even if it's not fixed because I do most of my driving with the electric motor, but eventually I will take a long trip with the car and we will see what happens.
