NHTSA Complaint #10070393 — 1997 FORD EXPEDITION

SPARK PLUG BLOWS OUT OF ALUMINUM HEAD. THIS CAR HAS ONE OF THE MOST EXTENSIVE SERVICE RECORDS PASO ROBLES FORD HAS ON RECORD; THESE ARE THEIR WORDS. IN OTHER WORDS THIS VEHICLE HAS BEEN MAINTAINED VERY VERY WELL AND TO HAVE THE PLUG BLOW OUT IN THE FIRST PLACE IS UNCALLED FOR. SECONDLY WE PAID TO HAVE A REMANUFACTERED ENGINE INSTALLED AND A FEW WEEKS LATER THE PLUG BLOWS OUT AGAIN. THIS IS SUPPOSED TO BE ON WHAT FORD CALLS A REVISED PART TO TAKE CARE OF PLUGS BLOWING OUT OF THE ALUMINUM HEAD. FORD WILL NOT GIVE US A STRAIGHT ANSWER ON WHAT THE REVISION IS; THIS COULD BE ANYTHING-POSSIBLY NOT EVEN RELATED TO THE PROBLEM. MY UNDERSTANDING IS THE PROBLEM IS THAT THERE ARE ONLY THREE THREADS GOING INTO THE ALUMINUM HEAD. APPARENTLY THE REVISION DOES NOT TAKE THIS PROBLEM INTO ACCOUNT BECAUSE IT ONLY TOOK A FEW WEEKS FOR THE EXACT SAME THING TO HAPPEN.
