When my car starts up, engine rpm is around 1500 or above 1000. If I would switch to reverse, the car sudden jerks back stronger and quicker than I expected even though my foot isn’t on the accelerator pedal and have pressed the brake lightly.

On 09/01/2026 at approximately 55 mph, I was driving with adaptive cruise control engaged. The vehicle ahead decelerated abruptly. My vehicle began braking hard with no input from me for a fraction of a second. A red BRAKE warning appeared in the instrument cluster with an audible alarm. I then applied the brake pedal hard. On first contact the pedal barely moved from its rest position and was extremely firm. About a second into my application, while still traveling at over 25 mph, pedal resistance dropped sharply and pedal travel increased substantially. I had to push the pedal several inches farther to get back to comparable deceleration. The pedal did not pulse or vibrate. I came to a matching speed roughly one car length from the vehicle ahead, and only because I kept braking hard. I did not see an MRCC Cancelled message, though the BRAKE warning occupies the same part of the display, so I cannot say whether the initial deceleration came from Mazda Radar Cruise Control or Smart Brake Support. No brake, ABS, or DSC warning lamp illuminated before, during, or after the event, and none has since. There were no symptoms beforehand, and the brakes have worked normally since. Failed component: unknown. I cannot determine whether the change in pedal feel came from the brake booster, the DSC hydraulic control unit, the master cylinder, or the driver assistance system handing brake control back to me. The vehicle has not been inspected by anyone and no service center has reproduced the issue. The vehicle is available for inspection if needed. If a driver assistance system is commanding brake pressure and withdraws it during the driver intervention, total deceleration can drop at the moment when the driver still wants to stop aggressively to avoid a crash. Suddenly, the driver has to find the extra pedal travel while still closing on the obstacle. I slowed to a safe speed in time. With less room, or less attentiveness, I may not have been able to.

Brake pedals do not have enough pedal reserve, it takes some time for it to come to a stop. The brakes don’t feel secure. We feel like the brakes are going to give up. It also makes a very loud scratching sound when reversing and pressing on the brakes.

Autobraking activates randomly. Mazda scans codes and returns the vehicle. They have refused to service or disable the system. the federal safety agency laws are dangerous and this tech is not ready for road use. Avoid Mazda at all costs!

After driving a few mile, the following two warnings come up * Smart Brake System Malfunction * Forward Radar Sensor System malfunction. If I turn off the car and then restart, the warnings go away. However, it comes back if I drive for a while again. I have visited dealership a few times for the same issue, they replaced the wheel bearing and brake switch. The warning disappeared for days and came back.

The car has a lot of vibration when driving 60mph and above. Have had this issue looked at more than 5 times and they had my card for 1 month at the dealership trying to find the issue. This started back in February of 2024 and I have purchased 4 sets of tires and nothing makes the vibrations of the seat, steering wheel go away. Originally it wasn’t vibrating while driving back in February of 2025 only when braking to which I said to them I think it’s the rotors that have an issue. They never check the rotors and said it was my tires that were cupped. I put new tires on the car and still the same issue and went back to the dealership in April of 2024 and let them know it think it’s the rotors. In fact it was the rotors they were warped and they balanced the tires again. The dealership recommended resurfacing the rotors to which I had done. A Couple of months later the vibration while driving started. Bought another set of tires had then installed, balanced and aligned and still vibration. I thought maybe it’s the brand so I bought another set of tires to which the problem is still there. Now besides the vibration while driving I have vibrations while braking again after the dealership put in new rotors back in Nov. 2024. When to the dealership on 06.26.25 let them know the vibration while braking is happening again and I think it’s the rotors. They check them and rotors are warped again about only 6.5 months.The service manager said she will resurface them for me for no charge but then the service advisor said if they do that that the resurfacing is going to make me have to change the brake pads as I will end up in the red since my brake pads are in the yellow right now. I said then don’t resurface because I am not paying for the brake pads when that should’ve been done the first time the rotors were warped. I feel like I risk my life everyday driving this car to work 34miles one way.

At 2:00 on a clear afternoon I was slowly coasting into a right hand turn into a parking space, and lightly tapping the brake to finalize the stop, when the car accelerated HARD forward over a curb and a sidewalk into the brick wall of a building. Airbag was deployed. My injuries were a nasty wrist contusion and bloody gashes where the airbag "door" deployed and I also had complete seatbelt brusing on my throat, chest and across my abdomen. This after traveling a mere 7-8 feet. At the time I was very shaken up and incredulous that such a thing could have happened logically, and conceded that perhaps I had made a mistake somehow. As I settled down later I became dubious, especially when I got behind the wheel of my rental car and 100% when I sat in my actual car at the wrecking yard. I am crystal clear I was depressing just the brake. Even if I had accidentally hit the accelerator instead of the brake (I did not) it would not have accelerated to the degree that it did. I am now scared of my car and am just hoping it is declared totaled by my insurance so I don't have to drive it again - any car but that one.

Brand new 2023 Mazda CX-5 with 150 miles on it experienced unintended acceleration while braking. Pulled into a parking spot with my foot on the brakes but the car didn't stop & even accelerated over a sidewalk and into a building. I experienced a bruise from the seatbelt. Airbags did not deploy. Someone could have been killed if they had been on the sidewalk. Car is currently at an auto body shop to fix the cosmetic damages, and once released, will have the car towed to our local Mazda dealership/service center to get the car inspected. In doing research on the federal safety agency's website, at least 4 vehicles (2-2023 Mazda CX-5s and 2-2023 Mazda CX-30s) have experienced this issue. Mazda needs to recall these vehicles and investigate.
