Consumer Description

APPARENTLY THE DESIGN OF THE TURBO AND THE ENGINE CREATES HOT SPOTS IN THE ENGINE, ESPECIALLY IN THE TURBO. THESE HOT SPOT CREATE SLUDGE BUILD UP WHICH EVENTUALLY EFFECTS THE PERFORMANCE AND RELIABILITY OF THE ENGINE. RESEARCH ON THE INTERNET SHOWS THIS TO BE A PROBLEM FOR A CONSIDERABLE AMOUNT OF OWNERS OF THIS VEHICLE. MAZDA HAS REFUSED TO CORRECT THESE PROBLEMS UNDER THEIR WARRANTY. ALSO LACKING BY MAZDA, SINCE IT IS APPARENTLY A MAJOR CAUSE OF LARGE BUILD-UPS OF SLUDGE, IS THE NECESSITY TO IDLE THE ENGINE FOR THREE MINUTES PRIOR TO TURNING OFF. THIS WAS NEVER EXPLAINED TO US WHEN THE VEHICLE WAS PURCHASED. *TR
