I purchased my used Lucerne Sept. 2013. After a 20 mile test drive to a friends auto repair store, we put it on the Hoist. I then reported back to the dealer that the car he was trying to sell me had a major oil leak, that the underside of the motor was covered with oil and that it was probably the front Crank seal. THAT made him jump. I ended up buying the car. The dealer repaired the problem under warranty, acted honorably and I ended up with a discount of $3k off their asking price and a beautiful navy blue luxury car for cheap.

Low oil indicator came on and said to shut off engine. Put in 1 quart of oil and happened again later. A Dye was put in oil and found oil pan leaking and Main Oils Seal, this is a dealer fix and I believe is the crankshaft seal. Have not gotten estimate yet but am expecting it to be expensive.
