I am submitted this report for the 12/6/2024 event. The form I submitted previously was for the safety incident that occured last night (1/9/2025). On four different occasions, the most recent being last night (1/9/2025), the vehicle has suddenly lost drive power while driving. The ability to accelerate is suddenly gone. When you press the gas pedal the engine revs, as if it is in neutral, but it ds not accelerate. When this happens, the vehicle is still in drive as indicated by light on the shifter showing drive and the fact the vehicle, just moments before, is driving. During all four instances, I had to bring the vehicle to a complete, put the car in park and then back into drive. On three of these occasions there was no pull-out lane and I had to bring the vehicle to a complete stop in a moving lane of traffic. The incident last night occurred mere seconds after making a left-hand turn with traffic coming up behind me at a higher speed then I was travelling. My safety, the safety all passengers in my car and the safety of other drivers are all at risk when this occurs. When this happens there are no warning lamps or messages that appear. After the third time it happened (on 12/6/2024), we took the vehicle to the Mazda dealership we leased it from and it was inspected and we were told they found nothing wrong with it. They noted they did some updates. They kept the vehicle from Monday 12/9 — Thursday 12/12. Less than a month after getting the vehicle back from the dealership this issue occurred a 4th time (on 1/9/2025 at about 8pm). We will be calling the dealership this morning and setting up an appointment for them to again inspect the vehicle for this safety concern. The vehicle is available for inspection.
