2015 Mazda CX-5 with 91,000 miles on it. Automatic transmission has failed. When I attempted to pull out into traffic the vehicle would not shift into 2nd gear and instead jerked hard and the engine RPMs revved up. I was not able to get the vehicle past 10mph. This failure with the transmission resulted in the oncoming traffic having to swerve and break to avoid a collision with me. The vehicle was taken to a Mazda dealership who did a diagnostic on it and found that the Mazda had an "internal transmission failure" and would require a full replacement. I asked if it would be replaced with the same exact transmission and was told "no, the defect was discovered by Mazda and has been correct for new transmission models." The manufacture knows about this issue. Luckily I escaped serious bodily injury. The problem has been confirmed by the dealer as well as an independent 3rd party transmission repair specialist. There were no warning lamps, messages or other symptoms prior to this incident to give warning.

After a 700 mile trip from arizona to california on the highway, my mazda's cx-5 would no longer accelerate. When pressing the accelerator and reaching 5 MPH the car would suddenly feel as if it were breaking, causing the car to lurch forward. This occurred when trying to drive down the street. Imagine if this were to happen while I was driving down the highway at 70 MPH.

Driving normally, suddenly at an on-ramp, car would no longer accelerate. I hit the gas a couple times and engine just revved, and the car was jerky as if struggling to change gear. Anything over 3,000 RPM it would not drive. I also noticed electrical problems with radio and lights at the same time. Thankfully, I was able to coast to pull over. Turned off car and re-started. Test drove the vehicle around the area and it happened again at over 3,000 RPM. Luckily this didn't cause an accident.

While cleaning our 2015 mazda cx-5 that was parked in our driveway, I ran the seat forward to vacuum under it. When moving it back, the left side of the seat would not budge. When we inspected all over underneath the seat we could find nothing impeding the sliding mechanism. The car had to be towed to our mechanic as it was unsafe to drive with the seat all the way forward. After some research and hard work, our mechanic was able to remove the seat and sliding component and replace the entire power slide unit (part # kdy2-88-4foa power slide lf-s ) for the driver's seat. He found that the cable to the power unit on the left side of the seat had broken. The right side appears to be weakening as well. Through his research, our mechanic found a tsb bulletin on this exact safety issue. (tsb #09-006-16) he explained that the ntsb had told mazda to correct the problem in subsequent model years but that leaves us, and probably others, in the lurch for a safety issue that shouldn't have happened.

While driving through stop and go traffic near a traffic light on a downward slope (maybe 10-15 degrees), I attempted to apply the brakes in order to come to a stop. When doing so, the brake pedal was being applied normally but the vehicle wasn't slowing down like it normally does. As a result, I pushed down on the brakes as hard as possible and while the vehicle slowed down more than it previously was, it attempted to lurch forward more and more. I noticed that the rpms were slowly getting higher while I was in the middle of applying the brake pedal as hard as possible, but the vehicle was coming increasingly close to making contact with the vehicle in front of me. Due to the vehicle being close to being physically stopped already, I placed the vehicle in park as quickly as possible and the rpms for the vehicle immediately climbed all the way to the red-line (I believe 6,500 rpms) and then returned to normal. Throughout the remainder of the trip (another 5-10 miles), the vehicle exhibited no noticeable issues. I called the local mazda dealership to see if any problems regarding the transmission were currently being investigated, but I was told that no recalls were currently open for a transmission problem.

I was going from r to d on flat ground. The gear indicator says d but when I press the gas pedal nothing happens for two seconds. Then the gear changes and the car jerked forward violently. My wife was scare about it, we have four cars, none of them will be like it. Also, when you going down hill, the gears will change violently, I will take this car to dealership next oil change.
