While beginning to turn into an interstate exit lane, all dashboard lights lit up, the engine died, and the car stopped. Power brakes & steering were inactivated. My husband was able to coast the car to the shoulder. My Mazda app said nothing wrong with car. Waited 3 hours for tow as we were out of state. The Mazda dealership found the high pressure fuel pump to have a malfunction. Two different technicians at the dealership related that Mazda was aware of the issue & had not yet issued a recalled.

On April 16, 2022, around 6:45PM, I drove my new Mazda CX5 (@ 3500 miles) into our church parking lot and turned right down the first row of cars. It was light out and the weather was pleasant. I turned right into a parking space with my foot on the brake. The car was facing and perpendicular to a sidewalk that was about 10 feet away. It was separated by a grassy median. When I depressed the brake further to shift from drive into park, the car surged forward and accelerated. There was a pedestrian on the sidewalk in front of the car. I turned the wheel to the right at a 90 degree angle to avoid hitting her. I kept pressing the brake but the car kept accelerating until it crashed into a large tree. The airbag deployed. Both the pedestrian and I were transported to the hospital. The pedestrian had bruises on her leg and hip, but fortunately was not more seriously injured and was released from the hospital. I was admitted to the hospital for contusions to the heart. The car hood was crushed and the car was totaled. The incident was terrifying. The police estimated the car went from nearly a standstill to about 40mph in about 15-20 feet. There were no warning lamps or messages prior to the accident. I checked the NHTSA website after the accident and downloaded 16 similar complaints where low mileage Mazda CX5s accelerated out of control when drivers were attempting to park or stop.

When the cylinder deactivation system triggers It causes the engine/car to shake and stutter. Somtimes it's suttle and other times if feels like the car is going to stall out. It's a vibration that makes it feel like your driving over cobblestones. This has been ongoing for a few months now. I'm taking it to the dealer tomorrow. It appears to be the same problem as the 2018-2019 Recall.

The contact owns a 2021 Mazda CX5. The contact stated that the fuel gauge was not operating properly. The vehicle was taken to the dealer and the dealer reprogrammed the Transmission Control Unit (TCU). However, the failure recurred. After taking the vehicle back from the dealer, the contact was driving at an undisclosed speed, when the windshield wiper inadvertently engaged, and several unknown warning lights illuminated. Additionally, the headlights inadvertently turned off and the steering wheel pulled the contact's arm down and the vehicle went to the median, running over a metal pole. The cruise control would not deactivate, and the brakes would not engage immediately. No injuries were sustained. A police report was filed. The vehicle was taken to another dealer, Hiley Mazda of Huntsville (6934 Hwy 72 W, Huntsville, AL 35806). The dealer measured the fuel level resistance range of the fuel level sender and informed the contact that the fuel level sending unit needed replacement. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 1,629.
