Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** you for the question. To answer your question, technically they can if you do not have the service done within the interval, but they would have to prove that you going 400 miles over the service caused damage to the vehicle. This is highly unlikely, if not almost impossible to do. I would not worry about it as you should not have any issues with this. I hope this answers your question. If you need more help or more information please let me know.
