2014 Mazda Mazda6

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 turned off.

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 front of my car.

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’m sure Mazda wouldn’t want any crashes, fires, injuries or deaths on their hands do this well established faulty switch that they refused to recall.

This SA supersedes the previously issued SA(s) listed below. The changes are noted in Red. SA-061/25 12/17/25 DESCRIPTION If you encounter any type of electrical concern (e.g, dead battery, engine no start, DTC(s) stored...), interview the customer before proceeding with normal MGSS diagnosis by asking if any aftermarket devices have been installed. Aftermarket devices may be the cause of the electrical concern. Below are a few examples of unusual electrical concerns caused by aftermarket devices. Examples: 1. Devices connected to the DLC-2 (battery discharge/DTC stored) 2. Devices plugged into the 12V outlet 3. GPS tracking device (engine no start/battery discharge) 4. Dash cam (DTC stored) 5. Non-certified USB cable (Apple Carplay™/ Android Auto™ will not connect) 6. Over-sized wheels/tires (incorrect GPS location) 7. DTC C0023:14 8. Decorative trim and/or cover on the START/STOP ENGINE button Example 1: Some electrical devices connected to the DLC-2 connector by insurance or mobile phone companies may cause: Battery discharge. The device may disrupt the CAN system battery saver mode. • IDS/MMDS will not communicate with the vehicle due to poor DLC-2 connection. The aftermarket device may cause DLC-2 female terminals to spread open.

This bulletin supersedes the previously issued bulletin(s) listed below. The changes are noted in Red. 01-008/23 06/05/23 Some vehicles may exhibit rattling noises from the engine compartment and oil leakage from the drive belt auto tensioner. This may be caused by insufficient sealing at the drive belt auto tensioner damper when the auto tensioner fully operates under both high ambient temperature and high load conditions. To eliminate this concern, the shape of the drive belt auto tensioner damper has been changed. REPAIR PROCEDURE If the tensioner is found to be "No Good" after completing the Drive Belt Auto Tensioner Inspection, replace it with a modified part according to the instructions on MGSS online:

There are currently 2 methods for cutting a new auxiliary key blank. A. Auxiliary Key Trace Cut Method • B. Auxiliary Key Code Cut Method 2019 and newer models require a 10-digit key code to accurately cut keys • 5-digit codes CANNOT be provided for 2019 and newer vehicles (the traditional 5-digit code from the key tag or driver's door lock cylinder is not sufficient and will not be issued for key cutting on these models). • Only Mazda-approved key cutting machines can process these 10-digit codes. • Many older key machines do not support 10-digit codes and cannot be updated to do so. In these cases, dealers will need to purchase one of the newer Mazda-approved key cutting machines capable of handling this requirement. • For a list of current Mazda-approved machines and purchasing options, refer to the Mazda Dealer Equipment Program or view the current Mazda approved key machines below.
