Mine did this on a 2000 mile road trip. First time it was when I floored the accelerator and the engine light came on and then when I turn the engine off it went out again. It went to the dealer and they couldn't replicates the issue again. I had to physically drive the car and really floor the accelerator hard for the problem to come up again. It turns out it was a sticking valve on one of the turbochargers. This was replaced under warranty. Last month I went on another road trip and it happened again momentarily but hasn't happened again since.
