“5.4l gas engine. Spark plugs have blown out of 2 different cylinders in 2 months. I have found only that this is a known issue for several models with this engine including the f-150. Ford had done nothing to address this faulty engine design. Both times my plugs blew out I was accelerating from a stop while turning left.”

“I have a Ford 1998 Expedition, eddie bauer edition. It has a 5.4 liter engine with aluminum heads. Three times I've had a helicoil blown out leaving me stranded. Now a spark plug has blown out breaking two coils. Ford has made this vehicle for years with this engine. All with the same problems of components blowing out of the engine. I feel it is Ford's responsibility to start a recall and fix this defect.”

“Went to store, came out battery dead, car wouldn't start. Had not left lights or any accessories on. Got a jump, drove to auto parts store. They checked alternator and battery and said battery dead, needed an overnight charge. Let them charge battery, put back in car, horn started blowing and would not stop despite my using both the key and key fob. Horn blew for 5 hours before I found out how to disconnect from google. Got horn to stop, and car wouldn't start. Ford dealer said anti-theft system had to be reprogrammed at cost of $250 plus tow to dealer. …”
