The 2023 Ford Expedition shows a pattern of electrical failures across multiple systems. Door controls quit intermittently—driver's side switches stop operating mirrors and windows even after dealer replacement of the module, then fail again. Displays are unreliable: instrument clusters and the 15.5-inch touchscreen go black while driving, leaving drivers unable to see speed, fuel, or safety warnings and unable to control climate or navigation functions.
Power system failures are the most dangerous. One owner experienced total loss of engine and electrical power while driving 30 mph on a highway with three children aboard at just 8,500 miles. Another had complete instrument blackout. Batteries drain unexpectedly—one owner got a low-battery alert on the mobile app and the vehicle wouldn't start at 48,000 miles.
Other electrical gremlins include spurious trailer-brake warnings causing sudden unintended stops, cruise control that self-adjusts upward without input (resetting from 35 mph to 55–65 mph, or to 85–100 mph), and mysterious loud booming and crackling noises from the vehicle at idle. Water intrusion into the battery junction box due to hood seal failure prevents starting. One flooded vehicle ignited and burned completely while submerged—the only vehicle in a lot of 20–25 flooded cars to catch fire—though the cause remains undetermined.

When: Rental vehicle (duration not specified)
Symptoms owners cite: Cruise control automatically resets to higher speeds; Multiple resets to 85 mph and 100 mph
Total power loss and engine shutdown while driving
