Owner complaint summary

Check engine light comes on flashing for a knock sensor. This has happened four times. Since it is flashing, car goes into limp mode and won’t go over 2000 rpm, low speeds and slow/no acceleration. It is dangerous due to happening on highways and going from cruising speeds to a crawl, with minimal ability to accelerate, very quickly. Sensor has been updated once and sensor has been replaced twice. Currently dealing with corporate after the fourth time of this issue happening. I am still fighting this issue and it’s looking like I will need an attorney.
