“Purchased vehicle new It took me a long time to understand what the issue was. I complained to Ford and they gave me account rep that has never driven manual transmission. When I contacted Ford the end result was they have found nothing and car is operating normally. My issue : driver assist on clutch. It auto revs the throttle and is extremely inconsistent. I can forward to 20 second videos it needed. Problem is with the clutch and brake pedal. Releasing brake pedal causes engine to rev anywhere from 900-1500 rpm. …”

“Rear view camera is not working and the infotainment display is freezes up every time after starting the vehicle. The entire infotainment system is inoperable until next ignition cycle. The key SAFTEY concerns is rear view camera doesn't work at all. This is huge issue to drive and park the car safely. Problem is happening for past one month and could not able to use the vehicle safely. Ford service is very bad and cant event schedule a service to check the issue. trying all options. This problem has been happening for 3-4 months intermittently and past 6 weeks its happening always.”
