My 2014 Lincoln Mkz Hybrid has experienced significant water intrusion and intermittent electrical malfunctions. During heavy rain, water saturated the passenger-side floor areas, including the rear passenger floor. The source of the water intrusion has not been identified despite professional inspection and water testing. After the water-intrusion events, the vehicle experienced intermittent electrical problems including the passenger-side window not operating, hvac/air-conditioning controls becoming inoperative, radio/front controls not responding, and at times multiple electrical functions becoming inoperative together. I also observed that moving the passenger seat sometimes appeared to coincide with the affected functions beginning to work again. I do not know whether the seat movement is causally related. An independent automotive electrical facility performed a diagnostic scan. Multiple communication-related dtcs were recorded across vehicle systems. Several were identified as current faults, including lost communication or invalid-data faults involving the front controls interface module, door control module b, gateway a and hvac control module. Other codes were historical/not current. The vehicle was subsequently inspected by a Lincoln dealer. The dealer performed water testing but was unable to identify the source of the leak. Some electrical connections near the floor were inspected without visible moisture or corrosion being found. The dealer also reported an intermittent loose connection involving communication with the gateway during diagnostic testing. The underlying cause of the intermittent electrical malfunction was not identified or repaired. The electrical malfunction occurred again shortly after the vehicle was returned and remains intermittent. Because multiple vehicle functions can become unavailable unpredictably, I am concerned about the reliability and safety of the vehicle's electrical/network systems. The vehicle remains available for ins.
