I suspect they'll try to get you out-the-door with a repair cost to you of hopefully under $10,000 to replace the short block. How will you convince Lexus that you (1) changed the engine oil and filter at the required service date/mileage schedule, and (2) that you used the proper engine oil viscosity and oil filter, and (3) that you checked the fluid levels and did not run the engine without oil or too little oil? Just asking...so you can plan in advance...
