NHTSA Complaint #10512198 — 2011 MAZDA CX-7

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
