I finally did get the problem solved. The dealer replaced the oil level/quality sensor. Also they discovered the oil pan was cracked. So it was replaced also. The problem was also accompanied with the smell of burning oil after I parked the car in the garage. That was in Dec and all is well so far. This was done under starmark warranty.
