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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle was at highway speed when the warning light for high engine coolant temperature came on with a warning message to stop the vehicle in a safe place. The engine stopped and I was almost hit by a semi-truck as I was struggling to move over a lane to stop on the side of the highway. Vehicle was towed to the auto shop and diagnosed with a crack in the cylinder head. There was no problems prior to this. My research has shown that this has become a common problem with this vehicle.
The engine will not turn off when pressing the start/stop button while the transmission shifter is in park.
The electrical component of the car does not turn off when the vehicle is in park and the push button disengaged. Drains battery and leaves me stranded. Can’t lock doors to prevent unwanted entry once this happens as everything is battery powered.
The vehicle remains ON when you hit the turn off switch. Sometimes it takes several jiggles of the gear shifter to turn it off. I reported it to Mazda and they said that they can't do anything. Seems to be a common issue: https://www.reddit.com/r/cars/comments/b77yli/my_2014_mazda_cx5_wont_turn_off_kind_of/ Thankfully, my car is still operating but I would like it to shut off every time the first time.
I as well as many other mazda cx5 owners have experienced the same issue where the suv will not power off when the push to start button is pressed. The suv requires you to power it back on and shut it off several times before it actually shuts down. The radio and other accessories will not shut off when the car is powered down. Resulting in serious issues possibly happening if the car is not shut down properly. Anyone could get in and start the vehicle back up if they wanted to. Stolen vehicles. Vehicles are unable to lock properly. Batteries are constantly being repurchased due to this issue.
There is a defect that leads to the car not turning off property. Reading on various forums, it seems this is a very common problem in Mazda CX-5s. I have spent over $1500 recently on this car, and now this? My battery dies overnight because the car doesn't not fully shut down in park. Again, this is all over the forums. People are getting stranded. It's terribly unsafe.
Car will not sense that it is in park. It constantly says to put car in park when it already is. The car needs to be turned On and off several times to get it to work and one time it took 45 minutes. It happens nearly every day. It’s been going on for months and I’ve had 3 shops look at it. I called Mazda as well and they acted like they never heard of such a thing. Searching online it is very common with the make and model and year of the car.
