This is a safety issue. The front collision assist is not working. I have returned the car to the Ford Dealer (Biener Ford) several times but the dangerous issue persists. I'm not the only one. There are many complaints listed on the web and the Ford Mach E forum. Ford needs to recall their EV Ford Mach-E vehicles and fix this dangerous safety issue once and for all.

The car gives two messages, "Front Camera Fault Service Required" and "Pre-Collision assist not available." The cruise control does not work, however, the front camera does work. I had the vehicle scan done at the Ford dealer and was told it needs a 7 hour software update, after which it may need cables replaced. I do not understand how software goes bad. I do understand something may have happened to cables but that would not be checked until they had charged me $ 1,400 for…

An error message intermittently pops up on my vehicle that says, "Front Camera Fault", causing collision assistance and adaptive cruise control to suddenly stop working. This is a major safety issue, as a failure of adaptive cruise control while under operation may lead to a risk of an accident. Ford is aware of this issue and has issued TSB 23-2155, but they are treating it like a standard repair and not covering vehicles out of warranty. This should be a safety recall. See…

Here is why: There are two interconnected problems. The first is that the "cruise control on/off" button is…
