NHTSA Complaint #11173789 — 2017 TOYOTA HIGHLANDER

I WAS DRIVING ON AN INTERSTATE WITH DYNAMIC SPEED CONTROL ON. THE CAR SLOWED APPROPRIATELY TO MATCH THE SPEED OF THE THE VEHICLE AHEAD OF ME. SUDDENLY SEVERAL WARNING LIGHTS AND MESSAGES APPEARED: MASTER WARNING LIGHT, CHECK ENGINE, CHECK AWD, GO TO TOYOTA DEALER, ENGINE POWER LOSS.THE CAR SLOWED TO ABOUT 35 MILES AN HOUR (IN A 65 MPH AREA) WHILE TRAFFIC IN FRONT OF ME WAS AT (OR ABOVE) THE SPEED LIMIT. I WAS ABLE TO SAFELY GET TO THE SHOULDER AND TURN THE CAR OFF. I TOOK A FEW MINUTES TO USE MY SMARTPHONE TO FIND THE NEAREST DEALER AND PLANNED TO GO OFF THE EXIT (WHICH WAS JUST A FEW YARD AHEAD) AND TRY TO MAKE IT TO THE DEALER ON SIDE ROADS. WHEN I RESTARTED THE CAR ALL LIGHTS AND WARNINGS WERE OFF AND THE CAR DROVE WITHOUT INCIDENT UNTIL I REACHED THE DEALER NEAR MY RESIDENCE, ABOUT 100 MILES AWAY. THE SERVICE REP AT THE DEALER ADVISED I HAD TRAVELED TOO FAR SINCE THE INCIDENT FOR THEIR COMPUTER ANALYSIS TO WORK AND HE HAD NO ADVICE EXCEPT TO GO TO THE NEAREST DEALER IF IT EVER HAPPENED AGAIN. I WOULD LIKE TO HAVE SOME INFO ON HOW TO AVOID SUCH AN INCIDENT AGAIN.
