When pressing the start stop button, the ignition may not turn off the accessories, even with the shifter in park position, and the vehicle engine shuts off normally the ignition stays on in accessory mode. This can cause battery drain/dead, possibly leaving me stranded in the dangerous situation. This has been unknown problem that is been refused by Mazda to create a recall. Right now it's the car not acknowledging it's in park because of a faulty switch, that Mazda clearly knows about and has had tons of complaints about and is well documented with NHTSA. How bad does this need to get before Mazda puts out a recall for all vehicles affected. Eventually, it will never be able to go to park and I may get in my car to drive it and it starts off in the wrong shift the wrong and I end up in a car accident. …
I think it is unfair that a manufacturing problem has been unnoticed and left to people to pay for. I am already paying enough for this car to also have to worry about a manufacturing problem that has been left unattended by the company. This certainly is very dangerous as I might have the cars battery die and have no way of getting immediate help and right now it's just the car not acknowledging the parking mode but what if one day the car starts using the wrong shift unknowingly to me and I end up in a car accident because of this? I wont be able to do anything as this has been left unnoticed and no recall has been made even with the dangers it presents to the driver and the car itself.

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 was informed and the dealer said that it was not a recall. The car was only inspected by my mechanic. There were no warning lights or messages in the car or symptoms prior to this happening.
The park position sensor doesn't work. The car doesn't recognize that the car is in park and will not turn off. This is a known issue with the mazda 6 2014 and I do not know why there hasn't been a recall. I shouldn't have to pay to have this fixed. Started in 2019. Sometimes it takes 20 or more times to get the car to turn off by shifting in gear and back into park or starting and turning off the car. If you can't get the car turned off you cannot lock the doors and it will run the battery down. I just want this to be recalled so the dealership will repair. Thank you, this is a very frustrating situation. Literally my arm gets tired from slamming the gear shifter into park trying to get the car turned off.
When you turn the car off the accessory stays on. In other words it doesn't shut off all the way. That is a hazard because the battery will go dead in time. I looked on the internet and found a lot of complaints about this issue with these cars. The car has a defective shifter switch. Mazda won't recall the part even though there have been many complaints. This is a defective part. If a part is defective they should recall the part. I don't see why I should have to pay $400.00 to put a $50 part in my car that is defective. My car is available for inspection upon request.
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
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.
Ignition does not turn off when pressing start/stop button draining battery with car completely shutting down while driving, coasting to the side of road almost causing an accident. Second time, car was parked, would not restart, had to get a jumpstart as battery was drained once again. Third time, car wouldn't restart at all and car had to be towed.
