One problem related to engine shut off without warning has been reported for the 2013 Lexus GS350. The most recently reported issues are listed below.
On July 14, 2014, I was driving at 70 miles per hour in the middle lane of a busy interstate when the engine of our Lexus GS 350 unexpectedly shut down. Despite heavy traffic, I was able to pull over, without incident, into the median emergency lane where the car came to a halt. I called the dealership and was advised by the service department that it would have it towed to them. I was also informed that no loaner vehicle was available. Because I was en route to pick up family arriving soon at the airport, I restarted the car and waited several minutes to ensure the engine kept running. I was able to proceed, pick up family, and return. The following day, the dealership picked up the car for evaluation. The cause of the engine shut down has not been determined at this time.
