Automatic Transmission Control Module problems of the 2020 Ford Escape

Vehicle: 2020 Ford Escape I am experiencing a recurring drivability issue with my 2020 Ford Escape. During normal or light acceleration, primarily between approximately 1,000 and 2,000 rpm, the vehicle intermittently jerks, surges, or hesitates. At the same time, I can observe slight rpm fluctuation. The condition continues to occur even when the vehicle is driven in sport mode. On some occasions, the vehicle has also accelerated suddenly and more aggressively than expected, making the vehicle’s response unpredictable. I have had situations where I nearly collided with another vehicle because of the unexpected acceleration. The vehicle has displayed diagnostic trouble code p0600 – serial communication link. The ignition coils and spark plugs have already been replaced, but the condition remains unchanged. I am concerned because the hesitation, jerking, surging, and unexpected acceleration occur while the vehicle is being driven and could affect safe and predictable vehicle control in traffic. I have not yet received a final diagnosis confirming whether the cause is related to the transmission, torque converter, pcm/tcm, communication system, speed control system, or another component. I am reporting this issue so that NHTSA has a record of the condition in case other owners of 2020–2021 Ford Escape vehicles are experiencing similar drivability and unexpected acceleration problems.

On 9/15/2025, my 2020 Ford Escape se began experiencing serious electrical and shift system issues: hard downshifting, “shift system fault” warning, inability to go into park, and failure to shut off without disconnecting the battery. I confirmed a related pcm recall was active and had the vehicle towed to art hill Ford for diagnostic and recall service. The dealership refused to perform the pcm recall, claiming my issue “didn’t match” the symptoms — despite clear electrical failure. Instead, they diagnosed a park pawl solenoid issue without scanning or physically inspecting the vehicle. I was told the issue was resolved, paid ~$1,400, and picked up the vehicle. Within 24 hours, new and dangerous transmission issues arose: harsh downshifting, loss of power, sudden high rpms, and dashboard warnings. I became stranded in the middle of the road and had to have the car towed again. After this second visit, the dealer claimed there were metal shavings in the transmission and now says I need a full transmission replacement (~$10,000). These shavings were not reported during their first transmission disassembly — which is highly suspicious and may indicate the damage was caused during or after their service. Replacing transmission fluid on high-mileage vehicles (mine has ~132,000 miles) is known to be risky and can cause internal failure if not done carefully. My transmission had no mechanical problems prior to this visit. I now believe the dealership’s misdiagnosis, failure to perform the pcm safety recall 1st, and service caused a safety-critical failure that they are refusing to take responsibility for. I am a veteran with a pregnant wife — we depend on this vehicle. Ford corporate has not provided assistance. This situation has left me without transportation and potentially with catastrophic repair costs due to service-related damage.
