Hi, my name is***** warning is telling you that the oil level is too high. The shop probably added a little too much oil. You should take the car back to the shop and have them correct the oil level.

Ok,...but I went today,..and they checked the oil level, and the Oil Stick, indicated that it wasn't over, showed that it was where it suppose to be,....So even if it shows that it is where it suppose to be on the Stick, can it still be to much oil in there I'm wondering?.....Is the Oil stick indicator correct or precise? ....or not?

I would have them remove about 1/2 quart of oil. The oil level sensor can be overly sensitive. The can probably get the light to turn off by removing a small amount of oil. The oil level should be checked after letting the car sit for 30 minutes in order to get an accurate reading.
