When I was pulling into my driveway, approx. 5-10mph with my foot barely on the accelerator, the car started accelerating on its own, almost hitting the fence. I was able to slam on the brake pedal and it stopped. It was such a hard stop, left a tire mark on the asphalt and took out some patches of my grass.

On February 14, 2023 around 3:30 - 4:30 p.m. (EST), I drove to the local WAWA. Upon entering the driveway of WAWA at a very low speed and depressing the brake the car failed to come to a complete stop. I pressed down on the brake as hard as I good, but the car did not come to a stop until hitting the security/safety bollard in front of the WAWA store. I did not get injured and no one else was injured. The front end of my car sustained over $4000 worth of damage. The insurance company repaired by car. I was asked by the insurance company what caused the front end damage. As I played the accident over and over in my head, I just could not see what I did wrong. My foot was on the brake. Also, I entered the entrance of WAWA at a very slow/low speed. After a few weeks I took the car to the Mazda dealer to let them know the car accelerates and engine revs. Also, the car jolts forward while decelerating from about 20mph to 10mph. The car dealer/repair shop could not replicate the problem. Was told to bring the car back in, if problem continues.

While driving on the interstate (continuously for about 4 hours) the vehicle suddenly lost power and the engine stalled. Power steering and power brakes were impacted and the vehicle was difficult to get off the road safely. Once stopped, it would not restart over a 30 minute period. A tow truck was called and it was taken to the dealer. A couple hours later when the dealer checked it, the vehicle started normally and drove without issue. A P0192 code was stored in the ECU so the high pressure fuel pump was replaced even though they could not reproduce the problem. The vehicle has 63000 miles on it now, but a similar sequence happened at 15000 miles. In that situation while driving at a steady speed all power cut out and the engine abruptly downshifted to the point where the tires squealed. After pulling off the road and stopping/starting the vehicle it seemed to drive normally again. We were traveling at the time with no dealer nearby, but when we returned back home we took it to the dealer and they found the same code P0192 and ran various tests and decided to replace the high pressure fuel pump even though it was driving properly. In only 63000 miles this vehicle has twice failed dramatically and without warning in ways that could easily cause an accident or injury. I am lacking in confidence that the root cause has ever been identified.

The car stalled while in motion on the highway with 56 miles left in the gas tank. This caused a very dangerous situation due to the fact that I could not accelerate at all, as the traffic was speeding past. I had to coast through traffic to the safety of the shoulder of the road. Once the vehicle came to a stop, it wouldn't restart and it seemed as if it never actually stopped trying to restart. I noticed a few things during this situation. 1. the check engine light came on 2. all the dash board lights appeared to come on 3. the emergency brake and hold button for city parking brake were flashing at the center counsel 4. the dashboard warnings rotated between, city parking brake, parking brake, cruise system disabled 5. the battery finally died after several minutes of this happening my family and I were brought to safety by a state trooper and had the vehicle towed to a gas station. We filled the gas tank, jumped the car and it has not had the issue since. Unfortunately the rear lift gate has only worked one time after the event but I am not sure what is going on there. I had this same issue happen once in 2019, and the vehicle restarted. I took it to a Mazda dealer and they said it may have been bad gasoline. The vehicle issue seems to match a similar issue mentioned in recall 3719F.

- Hobart, IN, USA

Loss of power to a complete shutdown while at highway speeds of 60-70mph with fuel tank reading 30 miles to empty. Tow was necessary to dealership. Replaced fuel pump. 2nd occurrence with 60 miles to empty. Broke down again while at highway speeds. Towed a second time to dealership. Replace high/low fuel pump. Was instructed not to operate vehicle below 1/4 tank of fuel. Major safety issue while at highway speeds with difficulty moving to a safe area. Seems to be a design or fuel pump issue.

Without any warning, while driving on a highway at approximately 65 mph, the car suddenly stalled. Thankfully, on both occasions, I was able to avoid an accident and pull over to the side of the road. Coincidentally, I also own a 2018 Mazda Cx-5 and in October of 2019, I received a recall notice (3719F, NHTSA #19V-497) for the 2018 car. The description in the recall sounds like the exact issue I have faced with my 2017 Mazda yet there is no recall as of now on my 2017.
