The front CV axles on my car have failed. It begun with a clicking noise and vibration when accelerating. I took the car to the Mazda dealership, and they confirmed the sounds but said they weren't able to diagnose the issue and that I would have to leave my car for them to figure it out. This places my daughter and my life at risk, as well as other passengers, due to the critical role the CV axles play in operating a vehicle. More specifically, the ability to properly control my steering movement while transporting my daughter to and from school is necessary and if not present, very dangerous. An independent service mechanic has confirmed this issue and indicated that this issue has been seen in many Ford and Mazda's recently. However, there is no recall. There were no warning lights or messages prior to the problem occurring. Again, when Mazda recently services my vehicle, they conducted a full-circle vehicle inspection and did not produce any concerns.

The car sometimes has a delay between going from reverse into drive. During the delay, the engine revs up and then it lurches forward. This seems to be happening more frequently with a longer time before the engine engages. This also occurred after stopping at a stop sign (and staying in drive the entire time.) the car has ~12,000 miles on it but this has been happening soon after I purchased it brand new from the dealer with less than 10 miles on the odometer.

At around 9000 miles my 2016 mazda 6 grand touring with tech pkg. Automatic is having transmission delays. When the car stop and the gear lever moved into neutral(n), reverse (r), and park (p) then back to drive (d). It has a 4-5 seconds delay before the gearbox being engaged. Also at 60+ MPH cruising on freeways, when step deeper into the gas pedal to increase speed for overtake the transmission has a choke, felt like the gear was forced into place.

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.

Around 7,000 miles, I began noticing that my car was not shifting properly or smoothly. Initially, I thought that it may have been something that I was doing. Upon shifting the car from park to drive/reverse, the car would lull for a moment, and then suddenly shoot into gear. At first, this was minor. As time as gone on, it has become more frequent and more intense; in one incident, the shift was so intense that my car actually "peeled" out. After reading about the experience from others on recall.gov, I took my car to my dealership to get examined & hopefully find some type of solution. The service department told me to "have someone stand outside of my car and video record" the car doing this. I explained that it is random and that I could not possibly have someone with me at all times to record this. Their response then was for me (as the driver) to record this on my own phone. I didn't even begin to address their suggestion or the safety concern of that. My fear is that my car is going to shift or accelerate so intensely that I hit something, or worse case, someone.

My car is automatic transmission. When I would release the brakes after stopping at an intersection, the car would not immediately go into first gear. It would sit at the intersection and then suddenly jerk into first gear. I would drive normally after that. Dealer reports I have a defective transmission and they are replacing under warranty.

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!
