2014 Mazda CX-5 power train problems

“I was waiting at a traffic signal to make a left turn, with my foot on the brake. The car accelerated aggressively, with no warning, like the pedal was pushed to the floor. I stood on the brake and shoved the shifter into park - coming to a stop in the middle of the intersection, Fortunately my wheels were pointed straight and the car did not race into oncoming traffic. My [XXX] father was in the car with me. Thankfully, my grandchildren were NOT in the car. You could smell the gas and brakes. It was NOT driver foot placement, nor was it floor mats. Vehicle has ~ 75K miles, and I am terrified of this happening again. I had driven this car regularly in rush hour stop & go traffic for years with no event like this ever before. Apparently sudden unintended vehicle acceleration is a recognized problem.”

“The contact owns a 2014 Mazda CX-5. The contact stated while attempting to turn off the vehicle, the vehicle failed to immediately turn off. After several attempts, the contact was able to turn off the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was 70,000.”

“After pushing the button to turn my car off, the engine turns off but none of the electronics does. I have to turn my car on and off numerous times to get the navigation/radio screen to turn off, I'm a single woman and I don't want to come back to my car to find a dead battery late at night with no one around. I was advised that Mazda was aware of the problem with the sensor #KDY0-46-040, but was not issuing a recall. https://www.cargurus.com/Cars/Discussion- t49115_ds799849?sntEmlId=1964374109#msg850430, which shows numerous people are having the same problem and Mazda has assisted some of them in having this part replaced at no cost. This issue should be a recall from Mazda. It's not a wear and tear kind of problem, after many complains they actually changed the specifics of the new part, showing that they know it was defective.”

“For the last couple of months every time I place my car in park and press the PUSH START/OFF BUTTON- the car does not completely shut off. So I start the car again, move the gear shift out of park all the way back into drive and back into park again in hopes when I push off button it will cut off. It is a gamble. Now I am having to cut the car on and off almost 6 times in a row to get it to cut off completely. Not only is it causing incredible wear and tear on my vehicle, it is a horrible defect that seems like it will be dangerous and costly in the long run. I think Mazda should recall this issue and fix it promptly!”

“WHEN VEHICLE IS PARKED AND THE SHIFT IS IN P POSITION THE IGNITION DOES NOT TURN OFF WHEN PRESSING START STOP BUTTON.THE IGNITION STAYS ON IN ACCESSORY MODE. I NEED TO START AND STOP NUMEROUS TIMES AND PUT SHIFT INTO R AND THEN P TO TURN CAR OFF. IT WOULD TAKE ANYWHERE FROM 3 TO 10 TIMES. I SEARCHED THE WEB AND FOUND THIS IS A COMMON PROBLEM IN 2014 MAZDA CX-5 AND THERE ARE NUMEROUS COMPLAINT ABOUT IT. THIS ISSUE LEADS TO DRIVER STRANDED AS WITHOUT PROPER SHUTOFF,IT RUNS DOWN BATTERY. MAZDA IS FULLY AWARE OF THIS ISSUE AND THEY HAVE RECTIFIED THE SHIFTER SWITCH WITH NEW PART # KDY0-46-040. THERE WAS A SERVICE BULLETIN SEND TO MAZDA DEALERS ON 12/22/15 AND 4/11/16 ON HOW TO ADDRESS THIS PROBLEM WITH BULLETIN NO. 05-004/16 AND NOW RECOMMENDING TO REPLACE THE SWITCH UNIT WITH NEW PART # KDY0-46-040. HOWEVER THERE IS NO RECALL FOR THIS ISSUE. MAZDA SHOULD REPAIR THIS DEFECTIVE PART WITHOUT ADDITIONAL COST TO OWNERS AS THIS CAN BE DANGEROUS AS YOU CAN EASILY LEAVE CAR IN ACCESSORY MODE AND CAR BATTERY WILL BE DEAD UPON RETURN. THIS HAS OCCURRED TO US MULTIPLE TIMES AND AS RECENT AS THIS WEEK ONLY.”

“TL THE CONTACT OWNS A 2014 MAZDA CX-5. THE CONTACT STATED THAT THERE WAS A MANUFACTURING ERROR FOR THE UPSWITCH BUILT INTO THE SELECTER LEVER COMPONENT IN THE GEAR SHIFT IN AN AUTOMATIC TRANSMISSION. THE SWITCH WOULD NOT TURN OFF ONE OUT OF EVERY THREE TIMES, WHICH DRAINED THE VEHICLE'S BATTERY. THE MANUFACTURER STATED THAT THEY SAW NO RECALLS FOR THE FAILURE AND REFERRED THE CONTACT TO NHTSA. THE CONTACT STILL HAD AN EXTENDED WARRANTY, BUT WOULD NOT COVER THE FAILURE. AN UNKNOWN DEALER ALSO STATED THAT THEY WOULD NOT COVER THE REPAIR COSTS. THE DEALER GAVE THE CONTACT A COPY OF A TECHNICAL SERVICE BULLETIN REGARDING THE FAILURE. THE FAILURE MILEAGE WAS 69,000.”
