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 redid some work.

I pulled into my parking space in front of garage door, I came to a complete stop and positively without any doubt, put my foot on the brake. As I shifted to park, all of a sudden engine loudly revved up and car suddenly and quickly accelerated through garage door. I want to make it perfectly clear, I DID NOT HAVE MY FOOT ACCIDENTLY ON THE ACCELERATOR WHEN CAR SUDDENLY ACCELERATED. Mazda checked the car and said nothing was wrong with the car. This has happened to many other people with Mazda and other makes and people are told too many times that there is nothing wrong the car when it clearly is not human error.

My 2014 mazda 6 EVAP system pops the p0451 when filling up gas to the first click. It goes away after a while if I take care to not fill up the tank all the way to the top. It is similar to a issue reported by recall 7414D for other 2014 mazda 6s. My car is not covered by the open recall, but it is experiencing similar issues. The p0451 goes on and off depending on how much i fill up the gastank.

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

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 had a (SUA) Sudden Unintended Acceleration malfunction. No, the car was totaled and towed away. My safety was put at risk as I was slowly pulling into a parking spot, eased my foot onto the brake and this malfunction caused my car to involuntarily jolt into a rampant high speed. It jumped a curb and crashed into a tree. My brake was useless in stopping this runaway vehicle. The only thing that stopped it was that tree! The airbag deployed and I was badly bruised from the airbag. Fortunately, there were no pedestrians or other cars near mine. There were no warning lights or messages before, during or after the accident. It happened so quickly because the tree was only a few feet in…

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 itâs the car not acknowledging itâs 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…
