Bought my truck with9 miles on it March 2016. Just broke 5000 miles on it. The only place I take my truck is sun toyota for anything. Just had a major leak from the 3rd light that flooded my truck, they did a great job of getting it covered from Toyota. Just bought a little boat and tried to put my truck in S mode and it won't go into S mode. Called the service department and they tell me I need to bring it in to have it put on the machine to see what could be wrong. How is it they don't do a full test on your truck when you take it in for service!

Update: Took my truck in today. S mode working now. Seems like there was something wrong with a connection when they replaced everything in my truck when it was in for the light issue.
