This happened to us a few weeks after we had bought our RX300 - turned out to be the oxygen sensor which (as those American sites referred to in the other reply mention) is really easy to disconnect when someone is fiddling with the engine. In our case we took it to our Lexus dealer and they checked, found the sensor was faulty, and replaced it -- all for no charge, which was a nice introduction to Lexus service standards.

Yes, we have checked the oil level regularly and it has never been under the minimum level. I guess my worry is that, being a complete dolt when it comes to mechanical things, I am transfixed, like the donkey stuck betweeen two equal heaps of carrots, between Lexus's injunctions not to let the oil get too low but also not to let it be too high!

I bought a 2002 RX300 in february (c.54000 on the clock), no problems except that on the first serious outing on the motorway we kept having the engine oil level warning light (amber) come on. We ended up putting about 3 litres of oil into the engine over a 600 mile trip but when we took the vehicle into our Lexus dealer they found no leaks and, apparently, no problem. SInce then I've found the light comes on intermittently when driving at speeds over 60 mph, often when we hit an incline or decline, but then goes off again when we decelerate. Has anyone experienced this? Is it just a hypersensitive sensor?
