Does anyone know why the AutoOff function suddently stop working? I changed the oil today, replacing it with Mobil1 Synthetic. Right away I noticed the AutoOff stop working. I drove the car around town all day never once seeing it coming on. I did notice the car is running cooler than usual as result of the new oil, other than that is out of the ordinary. I am thinking the oil is causing the car to run cooler and hence the HAH constantly thinking that it's in the warm-up mode, therefore, AutoOff is bypassed. Does anyone has any input?
