I OWN A 2007 MAZDA CX7. SINCE I BOUGHT THE CAR, AT 29K MILES I HAD TO HAVE THE FUEL TANK REPLACED. AT AROUND 34K HAD TO HAVE THE TURBO LOOKED AT BECAUSE OF BLACK SMOKE BLOWING ON MY BUMPER, MAZDA REPLACED THE PIPES. MY PIPES WERE STILL SMOKING, HAD TO TAKE OFF WORK, TAKE CAR IN AGAIN BECAUSE OF BLACK SMOKE, MAZDA TRIED REPLACING RINGS IN TURBO, STILL BLOWIN BLUISH WHITE SMOKE, NOW GETTING TURBO REPLACED. I HAD THE AIR COMPRESSOR REPLACED A ABOUT A MONTH AGO. NOW I HAVE A TICKING NOISE COMING FROM ENGINE AND I'M SCARED THE TIMING CHAIN WILL BREAK SOON. MAZDA NEEDS TO REPLACE THE TIMING CHAINS ON THESE MODELS. I THINK MAZDA SHOULD DO THE RIGHT THING AN RECALL THIS MODEL, YR BEFORE SOMEONE GETS HURT OR BREAKS DOWN IN THE MIDDLE OF NOWHERE WITH KIDS IN THE CAR. *TR
2011
SERVICE BRAKES
FROM THE TIME I PURCHASED MY MAZDA CX7 IN AUGUST 2011 I FELT THE BRAKES DID NOT APPLY PROPERLY. THERE WAS AN INCIDENT IN 2011 WHEN I APPLIED THE BRAKES AND THE CX7 DID NOT STOP I HAD TO BRING THE CX7 TO A STOP BY TURNING OFF THE ENGINE. WHEN TO DEALER AND TOLD NO PROBLEM FOUND. I WAS SICK AND DID NOT DRIVE CX7 REGULARLY AGAIN UNTIL APRIL 2013. CX 7 STILL HAD BRAKE PROBLEMS AND THIS TIME TOLD MASTER CYLINDER WAS BAD AND IT WAS REPLACED. AFTER LEAVING DEALER THE CHECK ENGINE LIGHT CAME ON AND WAS TOLD CX7 WAS RUNNING ON A LEAN MIXTURE AND THIS WAS CORRECTED. CHECK ENGINE LIGHT CAME ON AGAIN AND NOW TOLD BRAKE BOOSTER WAS BAD. BRAKE BOOSTER ORDERED AND TO BE INSTALLED IN A DAY OR TWO. AS ALSO EXPERIENCING A PROBLEM WITH AIR CONDITIONING. WHEN UNIT FIRST TURNED ON THERE IS A VERY LOUD BANGING NOISE. SYSTEM ONLY COOLS WHEN TRAVELING OVER 50-MPH. SYSTEM DOES NOT COOL WHEN IN TRAFFIC. A/C DOES NOTHING WHEN TEMPERATURE OVER NINETY DEGREES. I BELIEVE A/C IS AFFECTING PERFORMANCE OF TURBO ON MY CX7. MAZDA FIELD ENGINEER SAID THAT THE MORNING BANGING NOISE I AM GETTING IS TYPICAL OF ALL SIMILAR VEHICLES. THIS VEHICLE IS SERVICED EVERY 3,000 MILES AT WHICH TIME NEW SYNTHETIC MOTOR OIL AND FILTER ARE INSTALLED. THE PRIVATE MECHANIC THAT I USE ADVISES ME THAT HE BELIEVES A/C TO BE FAULTY AND TURBO NOT TO BE PERFORMING CORRECTLY. MY MECHANIC SAID BRAKE MASTER CYLINDER WAS DEFECTIVE FROM THE BEGINNING. *TR
