I bought a 2009 IS 250 about 4 months ago, so far no problems, but with the recent Toyota problems, I'm a little worried about accelerator problems arising from my Lexus. Am I overreacting? I know the Lexus hybrids are also being checked, but how about the other models? Should we be concerned with our Lexus? I emailed the Lexus dealership where I bought the car, but no reply.
