NHTSA Complaint #10016840 — 2001 MAZDA MPV

I AM EXPERIENCING A MALFUNCTIONING NUMBER 1 SPARK PLUG FOR MY 2001 MAZDA MPV DX. PRIOR TO THE CHECK ENGINE LIGHT ILLUMINATING, THE VEHICLE EXPERIENCES SERIOUS HESITATION WHEN SPEEDING UP. I LIVE NEAR MANY RAILROAD CROSSINGS AND THE HESITATION IS SERIOUS ENOUGH FOR ME TO QUESTION WHETHER THE VEHICLE WILL STOP ALTOGETHER. I HAVE HAD THE CHECK ENGINE LIGHT SERVICED THREE TIMES. EACH TIME THE DEALER CLAIMS THAT THE NUMBER 1 SPARK PLUG IS CRACKED. THE SPARK PLUG IS COVERED BY THE STANDARD WARRANTY, SO THE DEALER REPLACES IT WITHOUT QUESTION. I AM CONCERNED WITH THE SITUATION WHEN MY WARRANTY RUNS OUT, SOON, WHETHER THIS PROBLEM WILL CONTINUE. REPLACING THE SPARK PLUG IS NOT A TRIVIAL TASK. I CURRENTLY HAVE 39,000 MILES ON THE VEHICLE AND HAVE OWNED IT FOR 2.5 YEARS. THE STANDARD WARRANTY IS 3YRS/50,000MILES. I WOULD LIKE A PERMANENT SOLUTION TO THIS PROBLEM, WHETHER IT BE REPLACING THE ENGINE OR VEHICLE ITSELF. THANK YOU. SINCERELY, ROBERT PLATA
