NHTSA Complaint #11519280 — 2016 FORD FUSION

When driving vehicle on warm starts, vehicle stalls and engine loses power. Warm start means any time vehicle was driven, turned off, and then restarted after less than 30 minutes of being turned off. For example, when fueling at a gas station, or making a quick errand into a store or fast food restaurant. One once occasion, vehicle also stalled after shifting to drive after an extended period of idling (approx. 20 minutes - was idling hoping to avoid stall when beginning to drive again). In general, vehicle will start (but may need a few tried before turning engine over), and idles at 500 RPM, rather than expected 1000 RPM. On acceleration, when vehicle reaches 2500 RPM or greater, needle drops to 0 and vehicle shuts off while driving. On some occasions, vehicle will also stall/shut off when decelerating as well (particularly in parking lots or instances when one may drive and stop/slow frequently). I took vehicle to mechanic and learned that turbo charger was leaking oil into throttle body - both were replaced by mechanic, but issues persisted. The vehicle stalls while driving, putting the safety of myself, my passengers, and other vehicles at risk in case of collision due to sudden stall. The vehicle has been taken to my local mechanic as well as the Ford dealership - in both cases I was advised that the check engine light was not on, and that there was nothing they could do until the light came on or vehicle was stalling consistently. The vehicle is now stalling consistently, however dealer informed they are not able to do anything because the engine light is still not coming on. The dealer did confirm they were able to reproduce the issue, and my local mechanic also confirmed reproducing the issue. These problems began on or around January 5, 2023 and vehicle was first assessed by local mechanic on January 11, 2023.
