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

ENGINE AND ENGINE COOLING
MY WIFE AND I PURCHASED A 2007 MAZDA CX-7 FROM LITHIA MAZDA IN FRESNO, CA. IT WAS A BRAND NEW VEHICLE AND WITHIN THE FIRST 26,000 MILES, THE AIR CONDITIONING COMPRESSOR WENT OUT. THIS WAS COVERED UNDER THE FACTORY WARRANTY AND REPLACED. NOW MY THE SAME VEHICLE HAS 65,000 MILES ON IT AND THE COMPRESSOR WENT OUT AGAIN. I HAVE BEEN TOLD BY THE DEALERSHIP THAT THEY WILL REPLACE THE UNIT (FOR $1,800) AND WARRANTY IT FOR 3 YEARS OR 50,000 MILES. I FAIL TO COMPREHEND WHY THIS IS NOT ALREADY COVERED UNDER THE SAME WARRANTY. *TR
