[J Roc 328i]

I own a 2011 328i and the oil was changed 2,000 miles ago so I am confident the correct amount of oil is there and fairly fresh. Yesterday the car had read that the level was on the maximum line but today I was driving the car for 1 hour and the whole time it never displayed the level and said it was "measuring the engine oil level". I check for leaks throughout the engine compartment as well as under the vehicle every week and seem to not see any major leaks. Has this happened to anyone else and have any ideas?
