This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.

The incident occurred while operating a diligently maintained 2014 Mazda 6 Touring, overseen by dealership service. While driving, the check engine light illuminated, prompting an immediate halt. Upon inspection, a concerning observation was made: the coolant level was significantly low. Despite no apparent leaks, further examination revealed a crack in the cylinder head, allowing coolant to mix with the oil. This issue, specific to Mazda's 2.5L Skyactiv engine, has been identified as a manufacturing defect, independent of overheating. Notably, this problem has been echoed by multiple users, confirming the presence of defective cylinder heads in these vehicles. This flaw necessitates an expensive repair, absolving the vehicle owner of any responsibility. Despite the widespread occurrence of this issue, Mazda has declined to issue a recall for vehicles equipped with these faulty cylinder blocks. Online forums and discussions have highlighted numerous instances of identical cracks in the same location, affirming the prevalence of this problem with Mazda's 2.5L engines. This poses a serious concern for vehicle safety and warrants attention from both Mazda and vehicle owners. Additional information regarding this issue can be found through the provided links.

The contact stated that an orange light on the push start button alerted him that the vehicle was in accessory mode. In order to fully turn off the vehicle, the contact would restart the vehicle, place the gear in drive, engage the emergency brake, and place the vehicle back into park. The contact stated that this method did not always work and that he would sometimes have to make multiple attempts for the vehicle to shut off. The contact associated the failure with NHTSA id number: 10160553. The dealer and manufacturer were not notified. The vehicle was not diagnosed or repaired. The failure mileage was 106,000.
2014 Mazda 6 ignition switch issue. Keyless ignition switch - car will not turn off. Even if shift is in park the engine shuts off but the ignition stays on. Found on cars.com but Mazda has not recalled.

Vehicle push to start fails when shutting off car. The car's not reading that it is in park. Engine will shut off but all vehicle electronics will stay on and car can still be shifed out of gear. Dealership replaced gear selector switch which they said had a faulty spring.
For seemingly no reason, the vehicle will restart and stall while driving and multiple warning lights will illuminate. This has happened while driving slow, fast and while turning. When this happens, I need to immediately pull over and restart the engine. The check engine light turns on and indicates an abrupt voltage change issue, but soon turns off after a few power cycles. This started to happen more and more often, and more recently, I had the car not able to start as if the battery died. All my electrical components, such as headlights and hazard lights shut off and after about 10 seconds, they all turned back on and running normally. At this point my vehicle started up again just fine. This has nearly caused an accident a couple times and no mechanic has been able to diagnose the issue yet. Although, this issue seems alarmingly close to a recent recall that was announced for 2018-2019 Mazda relating to a software issue that causes unexpected engine stalling relating to the fuel-saving cylinder deactivation technology. Unfortunately, even though my vehicle contains the same technology, it wasn't included on this recall list.
Vehicle stalls out while driving at normal highway speed, 65 mph. Lights all come on on the instrument panel. Has been doing this more often now. Mentioned it to berge Mazda in AZ when taken in for service.
With no consistancey, the car would loose power. At times, I thought the car would loose full power, in the middle of my commute, I would be forced to pull over and shut the car off. Most times, the car would return to normal conditions. When I brought it in for repair, byers Mazda of columbus, told me it needed a tune-up. Once again, the car almost stalled out and I managed to coast into a parking space. Now the same dealership is informing me for the first time that the car has an I-loop system and the battery that should have lasted five years, now less than the 3 years old, needs to be replaced for over $500. I bought this car used with an extended warranty and although it was my mistake, the dealership never disclosed the I-loop system and the problems that go with it. This I-loop battery will apparently last 2-3 years only and is very expensive. I guess it is legal for dealership sales reps to misrepresent the car maintenance because they say it is my responsibility to know what I purchased. I will never buy from byers auto for any model car!
The contact owns a 2014 Mazda 6. while driving approximately 30 mph, the vehicle stalled without warning. The vehicle was able to coast to the side of the road. The contact powered off the engine. Once restarted, the vehicle was able to drive normally. The failure recurred twice and the engine warning indicator illuminated. The vehicle was taken to an independent mechanic for diagnostic testing, but a failure code could not be found. The vehicle was taken to D. dahle Mazda of murray (located at 4595 state St, murray, ut 84107, (801) 266-0033), but was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 46,000. Updated 10/10/18
Upon turning on my car (flat surface, middle of the day, already driven that morning), I received an at failure notice, master warning light, scbs failure notice, and a check engine light. The car had been seen 5 days prior for a routine oil change and inspection. All marks were noted as "green." The engine sounded fine, the shifting of the transmission smooth, and no issues were seen/felt/heard/noticed as of yet. The dealer refused to run a diagnostics test as it is a Saturday.
Driving through rain in our neighborhood and the car stalled and will not restart. Engine seize per dealer. We understand other Mazda's have been recalled due to this issue. We requested the car to be checked for a possible recall without success because our VIN does not fall in the recall. We offered to pay out of pocket for them to test it which they declined to do.
While accelerating on 2 occasions in past 2 months, the engine will lose power without warning. It is still running but will not go faster than about 10 miles an hour. The first time occured while pulling out on a road and almost caused a collision and the second time was on a busy interstate while passing a vehicle and had to coast to the side of the road. The engine light flashes and the stability control light comes on. It will work normally after restarting the engine and it clears the lights. I had it looked at by a Mazda dealership the first time and they said it was a cracked spark plug and replaced it. However, the problem just happened again.. please investigate as this is a significant safety concern!
This incident has happened about 10 - 15 times in the 6 months I have had this car. It occurs when the vehicle is stopped at a traffic signal, stuck in traffic, or any other time when the transmission is in drive and the brake is used to keep the vehicle stationary. The engine will be turning at idle speed when suddenly it revs to 4-5K RPM causing the car to leap forward, overpowering the brake. This has almost resulted in a crash several times as suddenly the car moves forward rapidly. I have noticed a small tendency for this to occur in the first few minutes of driving but it has happened anytime. I have seen no correlation to outside temperature. I have noticed perhaps a small increase in frequency when the car is stopped after high speed driving such as highway driving.
