Complaint Summary

ELECTRICAL SYSTEM

Owner Narrative

I experienced a sudden engine failure while driving my 2015 Toyota Highlander on Interstate 294 outside Chicago. I was driving about 75 mph in the far left lane. A warning message "Check AWD" came on the screen, followed by the Engine icon lighting up, then a "TRAC off" message appeared on the screen. I began to merge to the right across four lanes of traffic to get to the shoulder. As I was doing so, a beep sounded, and the message "Engine Stopping" appeared on the screen. The accelerator stopped working. I reached the shoulder and the car came to a stop just as I made it to the shoulder. The whole incident, from the time the first warning light came on until the car completely stopped, lasted about three minutes. Prior to this, there were no warning lights, and I had been driving the car without incident. The car had received all regular maintenance at proper intervals. Mileage was 86,100 at the time. There were five people in the car, including myself, my teenage daughter, her friend, and her friend's parents. We were driving the girls home from a summer camp. We are unharmed -- and possibly alive -- only because I was able to merge across four lanes of traffic and reach the shoulder before the engine completely failed. Just behind us and just ahead of us on this stretch of interstate, there is no shoulder. Semi trucks populate this very busy road. We had to sit on the shoulder for two hours waiting for a tow truck. We are all truly fortunate to be alive and unharmed. The vehicle is in the possession of [XXX] Toyota, [XXX] . The service department has diagnosed as follows: "Performed diagnostic and found codes P0300, P0301, P0302, P0303, P0306 engine misfire codes. Code P1603 Engine stalls out. P1604 Stability malfunction. Code P1605 Rough idle. Spark plug number 6 is damaged. Check piston with borescope, piston is also damaged." I am being advised to replace the engine at a cost of $8820. Toyota US has been notified. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5
