I purchased my 2011 IS350 four days ago. The first day i took it out i got 300 km before the engine shut down while on the freeway. All of the idiot lights came on. I let the car rest for 20 minutes or so with just the engine light and the anti slip light on while I called the dealer. They said to go ahead and drive it so I was able to get where I was going 20 minutes at a time. After 20 minutes the car would again shut down. It is still at a dealership and they advise that at this time they have no idea what has happened.
