On two different occasions the dash indicator stated as follows: "pre-collision assist not available". when this error message appears, the car does not accelerate properly. The transmission seems to fluctuate between gears, and the car will not accelerate, and the vehicle seems as if the pre-collision alert is engaging or attempting to engage, but does not however, stop the vehicle, rather, the vehicle hesitatingly or haltingly will not accelerate properly upon pressing the accelerator pedal. On both occasions, I immediately stopped the vehicle in a safe location, turned the vehicle off, and turned the vehicle back on again. It seems as if the computer module is reset upon turning the vehicle off and then on again. Upon turning the vehicle on again, in both instances, the problem disappeared. However, the most recent instance of this problem, upon turning the vehicle back on, the error message disappeared, and the acceleration of the vehicle returned to normal, but the yellow engine light remained on, until restarting the vehicle the next day.

On Saturday August 1, 2020, me and my wife drove a car after work around 6:30pm. This Ford Transit connect has been driving a month since we bought it. When we took on the road with around 30miles speed 10minutes after we left, suddenly a warning message came up said that "pre-collision assist not available". as we saw the message we had never seen before, we slightly reduced a speed below 25miles and kept driving. We slowly push an accelerator to speed up again, however suddenly we heard clunk sound, and the car shook back and forth. RPM indicator move abnormally. We tried to find a right place for pulling off a car, however we couldn't find it immediately. Around 3 miles drove, we pull off a car and turned engine off. After a while, turn it on again. A warning message is still on. A car still shook back and forth while we drove and return to home.
