2025 MAZDA CX-5 Complaints

Brake booster failure in less than two years of ownership. It seems to be an issue with A LOT of these models. Very unsafe to have any brake failure

The automatic emergency braking system prematurely and overly-aggressively takes over when I have full control of the situation. When it takes control it locks up all four wheels, each time almost causing a rear-end collision. It has done this on a total of 4 occasions under normal congested traffic situations. On or about 6/14/26 I was driving westbound on the Massachusetts Turnpike. There was a sudden traffic stop. I had sufficient distance to stop before colliding with the car in front of me and further had the passing side breakdown lane to divert into if necessary. The emergency braking software took over and locked up the wheels causing the person behind me to have a rear-end collision with my car. There was little-to-no damage and no injuries. The dangerous turnpike traffic conditions discouraged making a police report. Conclusion: System is overly aggressive and creates undue risk of personal injury. The risk far outweighs any benefit the system offers. - Plans to report issue to Mazda during next maintenance appt -No warning lights -Problem is re-occurring but not with independent entity (yet)

I previously reported the auto breaking system would slam on breaks prematurely. Now it was a factor in an accident where the Mazda CX-50 was rear-ended by a Ram 2500 truck at full speed on the highway. Car is incompaitated and I have suffered injuries.

On May 21st , 2026, while waiting in line to make a right turn (positioned 3rd in queue), the vehicles ahead moved forward. As I transitioned from the brake to the gas pedal to follow, the vehicle experienced an instantaneous engine stall and total electrical failure (NOT an i-Stop event). Pressing the gas caused the vehicle to slowly roll backward. When I immediately tried to reapply the brakes, the brake pedal became extremely stiff and nearly impossible to press down, failing to hold the vehicle effectively. The driver behind me began honking aggressively due to the imminent collision risk. I attempted to lower the windows to signal the other driver, but all electronic controls were completely dead. I had to quickly shift the gear into Park (P) and hit the start button to successfully restart the engine, which temporarily restored functions.

When approaching cars at an intersection, the brake warning does not give any warning, but the cars brake, lock up, and throw me and anything in the seat flying into the floor or side compartment. It was not even necessary to stop that quickly. Totally random and could cause an accident.

CRUISE CONTROL SURGES BEYOND NORMAL LIMITS, HAS TRIED TO TAKE CURVES ON EXITS SO FAST THE TIRES SLIDE AND I HAVE TO SLAM ON THE BRAKES. ALSO, WHEN PULLING OUT FROM BEHIND A CAR, THE CRUISE CONTROL KICKS IN TOO FAST AND IS FLYING TOWARD STOPPED CARS, AND I HAVE TO USE THE BRAKE TO STOP IT OR REAR-END THE CAR IN FRONT OF ME. ALSO, THE FUEL SYSTEM WOULD NOT ALLOW ME TO FILL UP THE GAS TANK, AND I WAS STRANDED. COMPUTER WOULD NOT OPEN THE FUEL TANK FOR ME TO PUT FUEL INTO IT. HAS TO PRY THE ENTIRE ASSEMBLY OFF AND BREAK IT. THEN FUEL WOULD NOT GO INTO THE FUEL TANK, AIR PRESSURE KEPT TURNING OFF THE PUMP. AFTER THOSE INCIDENTS GOT THE CAR BACK FROM THE DEALER AND TWO DAYS LATER IT WAS COMPLETELY DEAD IN THE GARAGE, NOTHING WORKED, LOCKS, BACK LATCH, ETC. WHEN THEY RECARGED IT THERE WERE DOZENS OF CODES ON.

My 2025 Mazda CX-5 includes a Traffic Jam Assist (TJA) stop and go feature. This feature allows the adaptive cruise control to move the vehicle in traffic with minimal drier intervention. As traffic advances the vehicle moves. If traffic stops, the vehicle stops. When clear of vehicles based on the set safe space setting in the adaptive cruise control, it resumes the predetermined speed set in the adaptive cruise control. The problem: While in "traffic jam assist" (TJA) mode, if changing lanes L or R to a lane that has vehicles farther away (clear lane), the cruise control radar/camera then sees a clear opening and begins accelerating to the predetermined speed on the cruise control. However - at this time the system fails to recognize a that another vehicle is farther ahead. maybe 4 or 5 car lengths ahead, and continues accelerating dangerously close to the next vehicle (I cannot say if it will stop or not because I have intervened to apply the brakes), cannot risk a rear end to another vehicle.The system fails to recognize that another vehicle is present after a lane change has occurred and braking or slowing as expected does not take place. This is a common repeatable scenario. The failure to recognize another vehicle after changing lanes is a serious and dangerous problem that should not be taking place. This poses an accident risk from an automated system that has a inherent flaw in its logic/design. The NHTSA should investigate this system and determine what corrective action can be taken to prevent a collision while using this system.

I rented this vehicle from Enterprise (EAN HOLDINS LLC) in Collierville Tn. on 5/19/25 I rented the vehicle to attend a funeral in Virginia. I drove 1803 miles there and back. While it was raining and cold, I used the seat heaters on and off when I noticed that my legs and gluts began to become irritated and inflamed. Once I finally was home late that night, I observed that I had been burned on legs and glut area. The areas were red and inflamed. That morning I had blisters and large red/purple bruises which I began documenting with photos. I went to see my doctor who stated that I had 1st and 2nd degree burns which he then photographed and documented in my chart and prescribed some meds. Today the areas are still numb but appear to be healing. I did report this incident to Enterprise locally and I also made a complaint with the company's corporate office 1800 numbers. These car seat heaters are extremely dangerous

The issue is that the rear window spontaneously shattered. My car was parked in the driveway at the time. I got into the driver seat, like usual, and closed the door with normal velocity. Immediately after closing the door, I heard a 'crinkling' sound that my brain couldn't identify. I looked into the back seat to see if I could see what had made the noise, but didn't see anything that answered that question. As I looked into my rear view mirror, before starting the car, I saw blue sky - which wasn't usual (the window is tinted dark). I turned around again, and saw that I was seeing Through the back window. My initial thought was that the hatch was up. I got out of the car, went to the back, and discovered an utterly shattered window. I would say that most of the glass bits fell into the car, but a fair amount fell onto the driveway. At first, I supposed a neighbor kid may have accidentally thrown a big rock and hit the window, but there was no rock to be found. I might have considered a branch from an area tree, but there was zero wind and no culprit branch. There was no obvious object that might have been blamed. I called my husband out to look and as I retold the story to him, I realized that the mystery 'crinkling' noise was certainly the window shattering in that moment. Btw, he had driven the car to the store in just the prior hour or two and all had been well. I contacted the Mazda dealership. They said their technician would have to look at it before authorizing it as a warranty item. We made the appointment, wrapped the window in Saran Wrap as best as able, and brought it in. They concurred that there was no obvious reason, that they could see, as to why it shattered. Nonetheless, Mazda did not authorize a full replacement of the window, but did authorize the dealership to offer a good will gesture of $300 toward replacement. There had been no indication that there was any impending issue and no obvious prior cracks or dings in the rear window.

TO NTSA - 2025 Mazda CX-50 Premium Turbo Plus - Purchased [XXX] - Less than 2,000 miles Driving north on [XXX] , I took exit [XXX] . When slowing to change to the right-hand lane, it surged then rapidly accelerated. Stepping on the brake did not slow it down, increased acceleration. To avoid hitting cars in my lane, I jumped the curb to the frontage road, continually pumping on the brake. The left front wheel and axle broke off and landed 20 ft away. The vehicle did not slow down; It was stopped by snapping a power pole in half. While trying to grab my purse, two Good Samaritans yelled at me to get out of the car, it was smoking and there were power lines overhead. Miraculously, I walked away. The Mazda salesman we purchased from was notified with photo. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
