Mazda MAZDA6 loss of power problems

Filed Jan 17, 2025 · CA

Software error/loss of engine power. No warning of this before it happens. The car completely loses power, and stalls or stops in the middle of me driving. This has happened on the freeway and risked my life as well as my husbands, and children. This same issue has been a previous recall and fixed in 2019 for my car, and now it is happening again.

There is a bearing in the crankshaft that looks like it’s not up to spec. No warning lights came on, car suddenly lost power on the highway. Fortunately no one was injured though it was a very scary situation. Mechanic took a look inside the engine and said a main bearing stud broke off and busted a hole through the short block. He said I’m lucky the engine didn’t turn into a grenade. Upon looking up the failure many other people have had the same issue with this engine. The exact same failure on the exact same bolt. Here are some links to some posts: [XXX] [XXX] [XXX] [XXX] Clearly I’m not the only one with this issue, and there are more examples of the same problem that you can find online through out different Mazda models that use the same engine. I can definitely have the vehicle inspected if needed, my mechanic took video of the damage as well. I could only imagine if this happened while there was more traffic on the road, it’s not safe. And the fact I can find more examples means there are probably more that never posted or reported the issue. the vehicle has less than 100k miles which a lot of the examples have the same issue at less than 100k INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My RPM'S reaved up real high while driving 60mph and all the sudden the car down shifted and I had to put car in neutral in order maintain control. The traction control light and heck engine lights came on same time, lost power to the car the navigation and radio and dash lights, had no power to drive train, had vechile dinogstic check done at O'Reilly auto and they told me it was a PCM power control module. And I called the mazda dealer in Fostoria ohio the macanhic told me the PCM power control module had been reprogram and I never received no notice on any recalls or the person I bought my car never either. My car is 7 years old and if it war reprogram it should not go bad that soon. Unless there is a problem with there components there using. But my car will cause a accident if I continue to drive it. I like my mazda6 2015 but I'm afraid after having the car doing what it did to me on the highway. I had no warning lights come on until the day I was driving down the highway when this problem occurred.

Vehicle displays low engine oil light about every 1,000 miles due to burning oil from faulty valve stem seals from factory assembly. Mazda has acknowledged the defect but plans to only refill engine oil. The defect could lead to possible injury due to low oil which could cause the engine to seize and cause sudden loss of power.

Automatic transmission failure occurred as follows: transmission disengaged while driving 35 MPH in city traffic (taylor street, columbia sc). Car lost power as if the transmission was in neutral. Warning displayed on dash "ats failure." I powered off the engine and re-started engine and drove approximately 500 feet before transmission failed again. Was able to drive to the mazda dealership after 4th attempt. Technicians labeled the issue as a "fluke" and they could find no reason for failure, although they did verify the code p0780 which stated to re-program the transmission. If I had been driving on the interstate (which I had been earlier in the day), the consequences could have been much more serious.

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!
