NHTSA Complaint #11486944 — 2018 FORD FOCUS

Yes, both the safety of myself as well as others is at risk. The engine shuts off while driving, which is extremely dangerous in many scenarios: on a highway - the risk of rear-ending at high speed, hazardous when passing another car on a two-way street, inability to leave the intersection safely etc. During regular operation, the vehicle loses power and enters "idle mode"; the car shakes a bit like choking, the engine shuts down, and no acceleration is possible. An error message " engine fault service now" appears. You are losing control over a car and cannot safely leave a line or an intersection. Turning the engine off and back on clears the message, and the vehicle typically runs back and runs without problems. The incidents happen entirely at random without any warning. There is no pattern, fast or slow drive, length or dynamic of the drive, the weather, etc. Happened to me multiple times. Around August 8th - the first observance, on an interstate highway, the car entered idle mode and died numerous times when slowing down. The car was dropped off at the authorized FORD dealer. The dealer cannot replicate the issue. Car picked up from the dealer around August 30th - throttle body replaced as per dealer recommendation. September 15th - same problem. The car shuts off during driving. No acceleration, same message. Fulls speed, city driving, lost acceleration mid-intersection. Car towed to an authorized dealer. The dealer cannot identify the issue, cannot replicate the problem and says everything is ok. On September 23rd, the car was picked up from the dealer, stating that they replaced the harness and resolved the issue. September 24th card enters "middle mode" while on the highway off-ramp. Unable to accelerate same error message. Miraculously avoids being rear-ended by the driver behind. The message clears off after tuning the car off and on. The vehicle operates normally after. Dropped the car off at the authorized dealer.
