My vehicle is automatic transmission and last weekend I was driving at the freeway with my family at 70 MPH on cruise and all of a sudden we got big jerk from my vehicle and the vehicle RPM started increasing the same time first I thought someone hit me from back but the gladly the vehicle was in other lane and he honked at me. I then I saw d light disappear on the panel and the vehicle was in very high RPM mode. I didn't know what is happening I safely tried to pull on the right and stopped to see whats wrong but couldn't found anything. I turned off vehicle for a minute and started again. It worked fine for 5 min and as soon as I reached 55 or 60 MPH the d light started blinking again and again I got high rpms and jerk. It almost had caused the accident as the other vehicle almost hit me from the back. It felt like engine braking. Then I drove very low spped on inner city road with my blinkers on to reach home safely. Now dealer is telling me that it will cost me minimum $3000 to replace the transmission. I think its a know issue to mazda and they should fix my vehicle transmission atleast. This vehicle is not safe to drive.

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.

I purchased my automatic transmission 2016 mazda 6 from the dealer as a certified pre-owned vehicle with only 1,800 miles on it. I had the vehicle for only a week when I started to run into issue. The result was a new transmission for my car at only ~2,700 miles. The transmission was slipping which made driving and acceleration unsafe. When I would come to a complete stop for a few seconds at an intersection, after releasing the break pedal, there would be a slight delay before my car kicked into first gear. The car would stall a bit and then it would kick forward very abruptly. The issue would also occur when I would shift my car from reverse to drive. The car would continue to roll in reverse a little bit after I've shifted to drive, then it would stall and kick forward very abruptly. I took the car into my local dealer to get it checked. I was able to reproduce the issue fairly consistently so I was able to show the service technician the problem. After the dealer spoke to mazda, the dealer informed me that my car needed a new transmission at only 2,700 miles. The new transmission would be covered under warranty.

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.

Bought my mazda 6 new on 10/04/15 with 40 miles. On 3/26/16 at 3245 miles the transmission failed, very similarly to another complaint listed on this site that stated that there were hundreds if not more transmissions failures of this model at very low miles. My car took at least six to eight seconds to enter drive from park. While driving, the car abruptly began slamming into much lower gears than necessary with little or no change in change in the accelerator pedal. Slightest of grade change on the road only exasperates the problem. I was devastated. Called the mazda service center and spoke to a service advisor who could not have more more apathetic. Curtly he tells me that the soonest they work me in was in 5 days. He noted that I should make my appointment online, and be sure to ask for him! You have got to be kidding son! No way! Unfortunately the only other service advisor in the place was a woman who seemed to be annoyed being there. Her own mistakes, which were many, made her angry and she acted like it was the customers fault. Not just with me either. I received nothing on day one for my car even being there. Not the work order I had signed. Nothing.. Day two I sign a work order for mazda to get the new transmission installed, again she gave me no copy. It really seemed to annoy her when I asked to both work order copies, as if it was something completely irrelevant. I wish I had followed my gut and taken my car out of there pronto. This was to be my last new car and I now want nothing to do with mazda. I am a 50 year old man who treats his cars gently. Nearly every mile on my mazda 6 was highway, the easiest best miles for a car when it come to wear and tear. This car is unsafe, I nearly rolled backwards into my neighbors car when I forgot about that long pause from park to drive one night. Mazda, get serious about this before someone gets hurt!

My brand new mazda 6 with only 6000 miles transmission quit on 3/21/16. The cars gears wouldn't engage until the rpms would hit 3000 and then the car would lurch forward. The dealer has ordered a new transmission. This seems to be a common issue with mazda 6 and mazda cx-5. A recall needs to be issued. This is a major safety issue. Someone could have rear ended me or I could have caused an accident. The dealer said this is the first they have heard of this but there have been 100s of reports about this. Mazda needs to issue a statement and recall before someone gets hurt.

The issue has been ongoing, but originally started in the summer of 2008 (car had roughly about 42,000 or so miles on it). Initially the car would increase the RPM up to 7000r in 5th gear (going to 6th) and then decrease causing it to do a hard jerk (someone else described it as being rear ended and that's exactly what it feels like). I took my car to the mazda dealership in marlow heights, md (while it was still under warranty) and the service person and I went for a drive (I was driving) he told me that he didn't notice anything off about it so I went back home. Fast forward to 2013 (the problem persisted through the entire time) when I took the car the arlington mazda dealership. This is where they did a test drive on it and came to the conclusion that my car's transmission is going bad (the car had about 49,604 or so miles on it). To date, the vehicle (which now has 58,360 miles on it) has trouble picking up speed is extremely laggy and in 5th to 6th gear will pull a hard jerk before it catches up with itself. I agree with the other owners who have this problem. Mazda needs to recall and replace the transmission because there's clearly a safety issue. After all, if another vehicle is following too closely behind the vehicle(s) having this issue they are going to undoubtedly be involved in a serious collision and there probably will be a fatality. Please note: I included the mileage the car has so that those considering purchasing this car will know they may not have long to enjoy it before they have a really dangerous and expensive problem on their hands.

I took my car to the mazda dealership after having experienced the 'at' light come on and a jolting in shifting gears and a real " drag" when trying to accelerate. I was told that the following fault codes "'torque converter clutch pressure control solenoid intermittent" and "transmission fluid pressure sensor/switch" indicate that I need a new transmission. I called the manufacturer because I was shocked that I would need a new transmission for a 5 year old car. I only average 12,500 miles per year, have had regular maintenance, have never heard of a transmission breaking down on such a " young" car. I believe they built the car with a poor quality product and now they will not take responsibility for it. Even prior to the current mileage I had noticed that the car was jerky and "bucks" and not powerful when accelerating but I chalked it up to it being a 4 cylinder car-- prior to this vehicle I had owned 6 cylinder vehicles-- so I didn't know that perhaps these things were an indication of a failing transmission. I tried to explain to the dealership that I felt that mazda may have a faulty/ cheap transmission and I should not be responsible for a new transmission but they would not hear me out. A transmission should not break down after only 5 years. My previous cars lasted until 120,000 -150,000 without major breakdowns. I am livid and I feel I have no recourse. I hope someone investigates this matter. What a huge let down!!! There is no " zoom zoom" in this car. What a farce!!!!! I don't know how I will pay for this. I can't be the only one complaining of this issue.

When the car is accelerating shift shock occurs when shifting from gear 3 to 4. It doesn't always occur when the transmission is cold, but is inevitable as the transmission warms. As time goes on the shift shock occurs under less and less of a load due to the wearing of a part in the transmission. The only way to fix the issue is to purchase a new transmission. When purchasing the transmission you have to make sure you get a transmission that has been redesigned, otherwise the issue will happen again. We talked to a mazda master mechanic that said mazda knows about the issue and even went as far as changing the way the transmission was made so the problem wouldn't continue. They obviously know the issue is their fault if they changed the design of the transmission, but will not issue a recall and own up to their mistake. From what we understand, the problem is with the housing of the transmission. This means you have no choice but the replace the entire transmission. Mazda made a mistake in their engineering, but will not admit the mistake. We may not buy another mazda because of this.

When accelerating, the car suddenly has no power, then shifts hard down, typically it happens shifting into 3rd or 4th gear. Under about a half pedal, it basically feels like a stall, then jerks you backwards, hard as it kicks into gear and accelerates. I'm told there is a service bulletin that there are transmission failures for this car. Unfortunately, we are out of warranty.
