Total loss of oil from crankcase. Burst oil line on my 2007 Toyota Avalon resulting in the pumping of oil onto the ground with no warning lights. This has been a documented problem for several years, as found on several consumer websites. The fix cost me >$450 not including towing to Toyota dealer.
