NHTSA Complaint #10780833 — 2014 MAZDA CX-5

I PURCHASED THIS VEHICLE IN APRIL 2015 AS A NEW VEHICLE LEFT OVER FROM 2014. REPEATEDLY, WHEN DECELERATING, THE ENGINE CONTINUES TO REV HIGHER DESPITE PRESSING THE BRAKE AND KEEPING MY FOOT OFF THE GAS PEDAL. THIS HAPPENS ALL THE TIME AND I'VE BEEN TOLD BY BOTH THE DEALERSHIP AND MAZDA THAT THIS IS HOW THE VEHICLE IS DESIGNED. I FEAR THE VEHICLE WILL NOT SLOW DOWN WHEN NEEDED AS IT FEELS AS IF THE ENGINE IS PUSHING TO INCREASE SPEED WHEN I'M TRYING TO SLOW DOWN. IT IS EXTREMELY DANGEROUS WHEN THE ENGINE GOES INTO OVERDRIVE FOR FAST ACCELERATION SUCH AS ENTERING A HIGHWAY AND THEN A RAPID DECELERATION IS REQUIRED SUCH AS WHEN ENCOUNTERING SUDDEN TRAFFIC. I'VE ALSO NOTICED OTHER ISSUES WITH THE ELECTRICAL SYSTEMS (BLIND SPOT INDICATORS WORKING INCONSISTENTLY; HD STEREO FADING IN AND OUT; BAD RECEPTION ON STRONG RADIO STATIONS) AND I BELIEVE THEY ARE ALL RELATED TO A BAD COMPUTER. IT SEEMS THE COMPUTER NEEDS TO BE REPLACED SINCE IT CONTROLS ALL ASPECTS OF THE ENGINE'S OPERATION.
