“Car was serviced on 25-oct at ~49k miles. No computer updates were done to the vehicle. 12-dec, I had new tires put on the car. 13-dec the car reported reduced engine performance and oil light came on. Pulled over, stopped car, waited a few minutes and restarted with no problem/lights. Drove a few miles, same exact thing happened again. Then drove for ~45 minutes when the car reported something like a system engine failure and the check engine light came on. Car was sputtering with no response from the gas pedal. Was towed to my dealership. …”
