Mazda CX-5 electrical problems

DOOR LOCKS FAILING. PASSENGER SIDE DOOR LOCK HAS FAILED TWICE: ONCE DUE TO LOCK ARM MISALIGNED AND NOW HAS JUST FAILED AGAIN. THE REAR HATCH HAS FAILED FOUR TIMES WITHIN MONTH. HAVE HAD DEALER REPLACE DOOR LOCK, BATTERY AND REAR CONTROL BOARD. THE ONLY WAY TO GET INTO HATCH IS WITH FOB, AS THERE IS NO KEY SLOT SO UNABLE TO OPEN REAR HATCH. THE CAR IS IN FLORIDA AND IS PARKED OUTSIDE.

WHEN CAR SHIFTED TO PARK IN ORDER TO SHUT DOWN ENGINE, THE VEHICLE OFTEN DOES NOT DETECT THE FACT THE CAR IS PAR WHEN BUTTON IGNITION IS PRESSED. MESSAGE APPEARS ON DASH SAYING TO SHIFT TO PARK TO TURN OFF POWER. REQUIRES USER TO PRESS BRAKE, RESTART CAR AND PUSH SHIFTER BACK TO PARK FORCEFULLY IN ORDER FOR CAR TO REGISTER PARK FOR TURNING OFF IGNITION. IF DRIVER IS NOT ATTENTIVE TO DASH MESSAGE OR DING WHEN EXITING CAR POWER REMAINS ON AND BATTERY IS DRAINED RESULTING IN DEAD BATTERY. THIS ISSUE HAS BEEN ACKNOWLEDGED BY OTHER MAZDA OWNERS, BECAUSE I FOUND REFERENCES TO IT ON THE WEB. TOOK CAR TO MAZDA DEALERSHIP AND THEY INDICATED THIS IS AN ISSUE ON OTHER MAZDA MODELS. THE DATE LISTED BELOW WAS THE LATEST INSTANCE THAT RESULTED IN COMPLETE POWER DRAIN AND REQUIRED JUMP START FOR RECHARGE. HOWEVER, THIS SEEMS TO HAPPEN FREQUENTLY, RESULTING IN NEED TO RESTART THE CAR IN ORDER TO REGISTER THE CAR IS IN PARK IN ORDER TO TURN IT OFF. I BOUGHT THIS CAR USED AND INITIALLY REPLACED BATTERY THINKING THAT WAS THE PROBLEM.

THE CAR HAS ABOUT 6300 MILES ON IT AND WE BOUGHT IT NEW. WHILE DRIVING ON THE HIGHWAY, EARLY JANUARY 2016, THE CAR "INFOTAINMENT" SYSTEM SHUT OFF AND RESTARTED ITSELF. THIS INCLUDES NAVIGATION, BLUETOOTH (MUSIC, PHONE ETC) AND THE OVERALL CAR MONITORING SYSTEM. IT HAPPENED ABOUT 4 TIMES DURING A 45 MINUTE COMMUTE. IT HAS HAPPENED A FEW TIMES PREVIOUSLY BUT ONLY ONCE PER TRIP, PERHAPS DUE TO SHORTER TRIPS. IT DOES NOT HAVE ANY DISCERNIBLE PATTERN. IT IS CONCERNING IF IT IS AN ELECTRICAL PROBLEM, AS THE WHOLE CAR IS BASICALLY ELECTRONIC, INCLUDING STEERING! (NO STEERING FLUID FOR EXAMPLE, ALL ELECTRIC) IT IS GOING TO THE DEALER TO BE CHECKED OUT THIS WEEK. I CAN SEE THE NAVIGATION SHUTTING DOWN IN THE MIDDLE OF A TRIP ALSO BEING A PROBLEM, ESPECIALLY IF IT'S THE MAIN FORM OF GUIDANCE.

TL* THE CONTACT OWNS A 2016 MAZDA CX-5. THE CONTACT STATED THAT WHILE ATTEMPTING TO STOP AT 20 MPH, THE BRAKE PEDAL WAS DEPRESSED AND FAILED TO RESPOND. THE CONTACT STATED THAT WHILE THE BRAKE PEDAL WAS DEPRESSED, THE VEHICLE ACCELERATED CONTINUOUSLY. THE VEHICLE WAS ABLE TO BE STOPPED AFTER THE BRAKE PEDAL WAS DEPRESSED TO THE FLOORBOARD. THE VEHICLE WAS TOWED TO A DEALER WHERE IT WAS DIAGNOSED THAT THE BATTERY FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 1,797.

SEAT HEATER NOT WORKING PROPERLY FROM DATE OF PURCHASE 9/25/15. PART ARRIVED FROM JAPAN INSTALLED 11/9/15. 3 HRS LATER CONSOLE PANEL STOPPED WORKING WHILE DRIVING 30 MPH, COULD NOT LOAD RADIO STATIONS, BLUE TOOTH, MAINTENANCE SCREEN - JUST ERROR MESSAGE. NEXT MORNING IT WAS WORKING BUT SEAT HEATER STILL NOT WARM SO BACK TO GARAGE. AT GARAGE ELECTRICAL TESTED OK. GARAGE STATES SEATS AS WARM AS IT IS SUPPOSED TO BE. BOUGHT 2 MAZDAS AT SAME TIME AND OTHER CAR CX-3 HEATER IS VERY WARM. AND HEATS QUICKLY. NOW WE HAVE TO WAIT FOR THE ELECTRICAL TO GO AGAIN THEN TAKE IT BACK IN. GOT IN CAR AND FOUND CAP TO THE SHIFTING LEVER WAS SITTING ON SEAT WITH OBVIOUS PRY MARKS , GARAGE SAYS IT WASN'T TAKEN OFF. THEY SAID THEY WOULD HAVE TO ORDER ENTIRE SHIFT LEVER TO REPLACE IT.

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.
