“AFTER DRIVING MY LINCOLN MKZ, WHERE PRESSING THE IGNITION STOP BUTTON AUTOMATICALLY PUTS THE CAR IN PARK, I DROVE MY FRIEND'S 2014 MAZDA6. I PRESSED THE IGNITION STOP BUTTON BUT EXITED THE VEHICLE WITHOUT PUTTING IT IN PARK. I DID NOT NOTICE ANY WARNING THAT THE CAR HAD BEEN TURNED OFF AND EXITED WITHOUT BEING IN PARK. THE CAR, ALTHOUGH STATIONARY WHEN WE LEFT IT, ENDED UP ROLLING INTO ANOTHER CAR IN THE PARKING LOT. MY INITIAL ESTIMATE IS THAT THE TOTAL DAMAGE WILL EXCEED $5,000 TO BOTH CARS. IF THIS CAR HAD HAD AN IGNITION KEY, I WOULD HAVE BEEN FORCED TO PUT IT IN PARK AS I REMOVED THE KEY.…”

“The Shifter Park Switch failed, causing the vehicle to say on when turning the vehicle off. This causes the battery to drain and created a bad cell battery. This caused the vehicle to turn off while in motion driving multiple times putting the driver and surrounding vehicles at risk. This vehicle has been inspected by the Mazda dealership/manufacturer.”
NHTSA complaint #11580088, 2024

“When I put the car in park and push the push start/stop button, the car shuts off but the accessories and middle console display stay on. I have to keep shifting the car between the park position and the drive position before I put it back to the park position for the car to completely shut-off. This car is available for inspection. As far as safety is concerned, the only thing I can think of is that if the car does not completely shut off the battery would drain and not be able to start the car. I took the car to my mechanic and he said that I need to take it to the dealer. The dealer…”

“At 70000 miles the transmission just got stuck into a single gear in manual. I drove it home and the check engine light came on. Before this problem the car would not go into park. Every time I put it into park I was unable to turn off the car because it thought it was still in gear. I had to fiddle the gear stick. The car also made a high pitch click (metallic) when shifting into 1st or Reverse from park. I took it to Capitol Mazada San Jose and they charged me $7000 to fix some transmission problem. I took it home and the clicking noise did not go away. I took it back to the dealer and they…”

“I was at a doctor's office and their parking lot has a large slope. I parked facing up the slope and applied the parking brake. When I exited the vehicle, I felt the vehicle slowly sliding backwards. I pushed rearward on the car to check if the brakes were holding which accelerated the roll. I jumped back in the vehicle and depressed the brake pedal to stop the roll. I replaced the rear brake pads and noticed extremely uneven wear. Additionally, the left-rear caliper parking brake actuator was bound-up and wouldn't function. I exercised the actuator to loosen it up a bit which should be just e…”

“The car will not go into Park right away. As previously reported, I have to start the car multiple times to get it into Park--can take up to 10 plus minutes before the car will go into Parkand shut off--only then I can lock the car! Very frustrating since it's a known issue and still has not been recalled”
NHTSA complaint #11662175, 2023

“The vehicle wont shut completely off when you press the start/stop button after shifting into "Park". The relay that tells the car it's in Park is faulty and the car wont shut off all the way. This will drain the battery and not allow the driver to lock the doors when they exit the vehicle. This is stranding hazard I've seen lots of YouTube videos and online forum complaints about this problem. It should be added to the recall list”

Engine 15

“The incident occurred while operating a diligently maintained 2014 Mazda 6 Touring, overseen by dealership service. While driving, the check engine light illuminated, prompting an immediate halt. Upon inspection, a concerning observation was made: the coolant level was significantly low. Despite no apparent leaks, further examination revealed a crack in the cylinder head, allowing coolant to mix with the oil. This issue, specific to Mazda's 2.5L Skyactiv engine, has been identified as a manufacturing defect, independent of overheating. Notably, this problem has been echoed by multiple users, c…”

Forward Collision Avoidance 1

“At 70000 miles the transmission just got stuck into a single gear in manual. I drove it home and the check engine light came on. Before this problem the car would not go into park. Every time I put it into park I was unable to turn off the car because it thought it was still in gear. I had to fiddle the gear stick. The car also made a high pitch click (metallic) when shifting into 1st or Reverse from park. I took it to Capitol Mazada San Jose and they charged me $7000 to fix some transmission problem. I took it home and the clicking noise did not go away. I took it back to the dealer and they…”
