Our 2018 Touring has no known oil or heat issues, but have noticed that when fully warmed up (red line pointing at the angle in the gauge), the marker drops like a rock when going through A 3 minute automatic car wash. The needle drops showing only 2 white lines like the car was just starting to warm up. After leaving the car wash, the car is up to normal operating temp within 1/8-1/4 mi. Outside temp was right at freezing. Car in neutral during wash. Never noticed it in any other car.
