2003 Ford Expedition engine problems

“The contact owns a 2003 Ford Expedition. The contact stated that while operating the vehicle, the check engine warning light illuminated and the front end of the vehicle was shaking abnormally, vibrating, and the vehicle stalled. The contact stated that while driving approximately 50 MPH, there was a loud booming sound coming from the engine compartment and the vehicle stalled. The vehicle was towed to the local mechanic who diagnosed that the spark plug had ejected from the engine cylinder. The engine cylinder was rethreaded, and the spark plug was installed; however, the failure reoccurred. The vehicle was not repaired. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The failure mileage was 230,000.”

“My Ford Expedition started randomly stalling and it stalled in the highway. The engine just shut down in the middle of the highway and it was such a scary a life endangering experience. This total loss of power in the middle of the highway when vehicles are traveling at highway speeds can cause death very, very easily to the occupants of the Ford Expeditions suffering this defect. I have been reading in many forums ( I have included the link to one of many forums) this is a common defect [XXX] ) many have Ford Expedition owners have experienced and have been very concerned and shocked that there was not recall. The issue is that the R303 relay (non serviceable fuel pump relay) fails very commonly on Ford Expeditions. In my Ford Expedition, the relay was melted. The fuel pump relay fails and cuts all current going to the fuel pump causing the engine to stall. This is a life-threatening risk caused by a defective fuse box with a defective fuel pump relay (R303). There were no warnings, the Ford Expedition just stalled randomly.”

“The contact owns a 2003 Ford Expedition. The contact stated while driving 45 MPH, the engine was misfiring, and the contact smelled a burning odor inside the vehicle. The check engine warning light was illuminated. The contact was able to drive to his residence. The contact stated that the failure had been reoccurring while driving. The vehicle was taken to an independent mechanic on five occasions where it was diagnosed that water was leaking into the ignition coil. The independent mechanic installed silicon around the boot to prevent water from leaking into the coils; however, the failure persisted. The dealer was notified of the failure and informed the contact it was not a known failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 196,000.”

“This vehicle has a faulty engine. The aluminum that Ford used to create the top end is too thin to support the pressure of the engine. As a result spark plugs explode from the engine at random with no warning. This has happened 5 times even after replacing all spark plugs, numerous coils and having kits installed by a mechanic sold by Ford to address the issue. $475 per kit from Ford. This is an enormous safety issue. The last one that blew out was on the highway with my two toddlers in the car.”

“THIS IS THE 2ND TIME IT HAPPENED TO MY 2003 FORD EXPEDITION. WHILE DRIVING HEARD A LOUD POPPING NOISE, FOLLOWED BY CONTINUOUS POPPING LOUD POPPING NOISE LIKE A BROKEN EXHAUST MUFFLER, SOUNDED LIKE A MOTORCYCLE. AFTER INVESTIGATING, FOUND OUT THAT THE #3 SPARK PLUG POPPED OUT (EJECTED) OF THE HEAD CYLINDER, BROKE THE SPARK IGNITION COIL. WHEN THIS HAPPENED, I SMELLED FUEL, AND SAW SMOKE COMING FROM UNDER THE HOOD, SO I DID NOT DRIVE THE CAR AND TOWED THE CAR HOME. I HAD TO REPLACE THE IGNITION COIL AND SPARK PLUG AND REINSTALLED THE SPARK PLUG BUT IT SEEMED TO BE STILL LOOSE, SO I TOOK IT OUT AND PUT THREAD LOCK AND REINSTALLED IT BUT DID NOT TIGHTEN IT TO THE MAX AND DID NOT START THE CAR TILL AFTER 24 HOURS SO THE THREAD LOCK WILL HOLD IT IN PLACE. YESTERDAY THE SAME THING HAPPENED TO #8 SPARK PLUG, IT ALSO BROKE THE COIL, AND WHEN I TRIED TO INSTALL THE NEW SPARK PLUG, FOUND OUT THAT THE THREADS ON THE HEAD CYLINDER WILL NOT GRAB THE SPARK PLUG, AND NOW I AM STUCK WITHOUT A CAR. WHEN I ASKED AROUND, PEOPLE SAID THIS IS A COMMON PROBLEM ON THE FORD EXPEDTION. THIS IS DANGEROUS AND COULD KILL SOMEONE IF THE ENGINE CAUGHT ON FIRE, BECAUSE I SMELLED GAS AND…”
