Lexusfreak,
The issue turned out to be a very positive experience. Lexus dealer in San Antonio had the car towed to dealership, provided us with a rental, and had the car back to me in a week all at no cost! Luckily, we had taken our es to the toyo dealer every 4000 miles for the oil change, so we had a print out from the toyo dealer to prove it. Overall, I'd give Lexus an A+ on this one. :D
