2014 Mazda MAZDA6 transmission problems

Filed Oct 4, 2025 · Driver assistance, Transmission · CA

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.

Early 2014 mazda 6's were equipped with defective transmissions. To the best of my understand a bearning of the wrong diameter was installed leading to an initial symptom of a high pitched whine at highway speeds. Mazda's solution is to replace the transmission, but if it's out of warranty this comes at the customer's own cost (~$5,000). There has been a tsb about this for years now #05-005-15-3027a. The issues are that there is no telling when the symptoms will occur and when I asked mazda what would happen to the transmission if I wasn't replaced, they declined to give me an answer. It is of concern to the safety of drivers that mazda deal with this problem.

Engine won't shut off sometimes when automatic transmission is in park. Push the engine off button the engine is off accessories and instrument panel lights are on as if trying to start the engine. Push the engine start button starts the engine. It'll keep cycling these two mode and can't turn off engine completely. Dealer knows about this problem occurring in mazda6. $400 to replace shifter assembly. They suggest I shift the transmission into neutral w/ brakes on to turn off engine, then shift to park. Chance of accident increase with this "suggestion".

Problem with shift control/park switch.. Car would be in a stationary position and ignition would be shut down. Interior controlled items (I.e. Radio, heat/air system, lighting, etc. Would remain on and would not shut off. I would attempt to start/restart vehicle to see if the car (and all systems) would shut down - they would not. Only way I could completely turn off the car and all systems was to place the car in reverse or drive mode and then put the car back in the park position. This option worked for a short while and then it stopped working. My battery was completely drained and I ended up replacing my car battery and ultimately I had to take my car into an authorized mazda dealer to have the gear park switch button replaced. Dealer stated they had numerous customers that experience same problem and resolution. I checked online and saw many customers also experienced same problem and same necessary repair to the vehicle. Battery replacement was approximately $130.00 and the gear/park switch repair work was $245.37. I have a copy of the invoice for the replacement and repair work, but am unable to scan.

Often when shutting off the car, the engine shuts off but the ignition and auxiliary power remain on. There is a message on the dash requesting to shift lever to p (park) but the lever is already positioned in p. It will take several attempts of shifting in and out of p to get the car to completely shut off all power.
