 I used to have great faith on Toyota until I realized my 42 K mile 5 year old toyota has an engine problem that is truly a manufacture defect!  I bought it when it was 17 K miles.  In May 05, I noticed oil light on and checked there was NO oil left in my engine at all.  Immediately I took it to a very good car repair place and changed oil and they did not detect any leak.  The assumption then was the previous oil change was not done properly; then 6 weeks later (yesterday) the oil light came back on and same issue - NO OIL in the car.  I am not very pleased with the engine problem but it seems to me Toyota won't do anything about it which is unacceptable.
