NHTSA Complaint #11694848 — 2023 FORD MUSTANG

While driving up hill in low gear, the vehicle suddenly will jerk, a service light will come on, and a powertrain warning will occur. When this happens, it warns that the pre-collision assist is unavailable, as well as the exhaust mode selection. Once this occurs, the vehicle becomes much more difficult to drive as the rev match no longer occurs, the vehicle no longer increases revs as you start releasing the clutch, and when in gear it becomes more jerky as you are driving along. I don't have the experience but I suspect it is essentially in a low power mode with minimal computer aid. After being able to pull off and turn the car off for a number of minutes (not off and on as that does not resolve it), the vehicle returns to normal. This has happened twice now while driving on the same section of roadway in almost the exact same spot. I previously called the dealer after the first time and they told me if it happens again to bring it in. They did not seem interested in looking at it. I will be hopefully doing that tomorrow. I am not sure if it is related, but the vehicle did seem like it was running rich earlier in the day (a slight smell of gas when driving by).
