NHTSA Complaint #11681193 — 2022 FORD MUSTANG MACH E

The Adaptive Cruise Control indicated speed lags when user changes speed. The lag will fluctuate from non-existent to 4-5sec at times. It occurs at different speeds and for different changes (e.g., speeding up to 45mph or speeding down to 25mph.) It also occurs when changing speeds in different increments (e.g., one click up for 1mph increase or hold down for 5mph decrease.) The lag is only in the display and not the actual drivetrain, meaning that the selected speed in the Adaptive Control indicator is not relaying the selected speed even though the car itself is changing speed. This is a safety issue as you don't know whether the car has registered a speed increase or decrease for several seconds (which at higher speeds is certainly not safe.) There was an OTA related to the Instrument Control Panel sent earlier this summer that was successfully installed, IPC-25.7.46, however this may be a coincidence. After calling multiple times to Ford, including their OTA update team, their EV Technology Team, and a generic Customer Experience team, I was told to bring it into a dealership AND submit a complaint to NHTSA. The dealership identified modules that required updating but that did not fix the issue. Ford has NOT been helpful and their Customer Experience reps have been dismissive of the seriousness of this issue.
