“While driving in Oyster Bay NY on a mild day, around 75-80 degrees, engine fan started get louder and louder as if the truck was in a high heat condition. Fan only kept getting louder, i was able to access the digtial temperature gauge and temp was reading over 250 degrees. However no warning light or message came onto the screen.

The dealership subsequently advised us to disable automatic stop/start. We have done so and have not experienced another shutdown with it disabled. However, the vehicle continues to jerk or buck…”
