The vehicle exhibits a repeatable low-speed driveline-related problem consisting of pronounced clicking or clunking from the driver-front area, fore-and-aft jerking, and harsh engagement during deceleration and light on/off-throttle transitions, particularly around 15-17 mph; the behavior can become significantly worse over rough or uneven terrain. The exact failed component or system has not yet been identified. The vehicle is still essentially new, with fewer than 5,000 miles, and has not yet reached its first scheduled service interval, so it has not yet been formally inspected for this condition. No warning lamp or diagnostic message has appeared. …
At stop signs, in a row of 3 or 4 cars, on the 3rd or 4th stop, I apply the brake but it accelerates as i am braking, moving forward 8 or 10 feet. Over the course of 1800 miles, this has occurred 3 or 4 times, narrowly avoiding collisions.
The contact owns a 2022 Mazda CX-5. The contact stated while driving at various speeds, the vehicle stalled without warning. The contact stated that moments after the vehicle stalled, the vehicle independently accelerated. There were no warning lights illuminated. The contact stated that there was an abnormal fuel and burning odor inside the vehicle. The vehicle was taken to the local dealer however, the mechanic was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 3,314.
The vehicle unexpectedly caught fire and the results could have been catastrophic. Almost new car under warranty. All details are in the uploaded PDF letter and photos. I have contacted Mazda and they claim they do not investigate, only insurance company will investigate. My insurance company will pay me for the total loss but does not plan to investigate. I think this is dangerous and unconscionable. Thank you for any help or guidance.
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 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). …
Car "died" while idling at a traffic light. It started but would not start several hours later and car was towed to mechanic. Diagnostics "determined "after several days that car needed an ECM. ECM was ordered and replaced, along with the battery. This took several weeks, in the meantime, I had to rent a vehicle. Vehicle picked up on May 29th and driven 250 miles and car sputtered, hesitated, slowing down in heavy traffic at high speeds on highway, putting other drivers and myself in a very unsafe situation. Several days later this happened again while traveling back home, again, at highway speed putting other drivers and myself in high risk situation. (This happened several times during both trips.) As I was focused on the road, I did not see if any messages were displayed. After returning home, the mechanic was informed via voice mail and again via telephone. …
The car has signs of current recall in other Cx-5 Models. Hesitation with acceleration or driving at high speed, reduced power, not responding appropriately when accelerating or would accelerate on its own, strong smell of gas after the car has been driven and is parked. I know there is currently a recall for a gas pump failure. There is no engine light on.
