Driver Assist & Collision Avoidance complaints by model year
The vehicle was traveling at highway speeds when it experienced a sudden, violent lateral jerk to the side, causing immediate side-curtain/seat airbag deployment prior to impacting the center divide. I believe there was a sudden, catastrophic mechanical failure of the front suspension componants causing a partial detachment of the front driver's side wheel. This failure mirrors the exact defect described in NHTSA Campaign 24V834000 / Mazda Recall 7925J regarding un-torqued front suspension fasteners. We believe our vehicle suffered from this exact factory build issue despite falling outside the initial recalled VIN list. Insurance claim to follow.
NHTSA complaint #11751702 — an unverified report by a vehicle owner.
Was braking with traffic and all of a sudden the emergency braking kicked on and brought the car to a stop from about 40 miles per hour with no immediate threat of collision. Brakes were being applied manually and had plenty of room infront of the vehicle and traffic was not stopped. Nearly caused the vehicle behind to collide into me. Very uncomfortable whiplash feeling experienced and my unsecured belongings in my car went flying.

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.
NHTSA complaint #11746992 — an unverified report by a vehicle owner.
FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
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.
NHTSA complaint #11742406 — an unverified report by a vehicle owner.
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.
NHTSA complaint #11742408 — an unverified report by a vehicle owner.
I am reporting a severe safety defect on a brand-new Mazda CX-50 Turbo Premium Plus involving a complete failure and malfunction of the Advanced Driver Assistance Systems (ADAS), specifically the proximity, forward collision, parking collision, and automatic emergency braking sensors. The safety sensors continuously malfunction, creating an immediate and erratic hazard while driving. The chief concern is the risk of uncommanded, sudden automatic emergency braking at highway speeds, or the complete failure of critical safety warning systems during a real collision event.Upon identifying this safety risk, I contacted an authorized Mazda dealer to arrange an emergency repair. The dealership explicitly promised a loaner vehicle so they could hold my car safely for diagnostic testing. However, when I arrived, the dealership reneged on the loaner vehicle and refused to check the car into service.Instead, dealership sales and service personnel drove my vehicle into the service bay and instructed me to get inside the cabin. A staff member then entered the vehicle settings menu and manually muted the auditory safety alerts to conceal the active sensor malfunction warnings. I immediately protested, stating that muting a critical ADAS safety warning system was unsafe, did not diagnose or repair the defect, and put my life and public safety at risk. Despite my clear objections, the dealership's management instructed me that I must continue to drive the vehicle with the disabled/muted safety systems anyway and to bring it back if anything else happens.When I refused to accept this hazardous vehicle modification and sought alternative resolution, the dealership owner issued a written communication banning me from the property, entirely refusing to honor the manufacturer's warranty or perform mandatory safety repairs. The vehicle remains unrepaired and unsafe to operate on public roads due to random sensor failures, and the primary local dealer has outright refused service.

NHTSA complaint #11742213 — an unverified report by a vehicle owner.
Emergency brake came on as I was backing out of parking space, pausing to double check for traffic not seen on camera. The emergency brake froze on "on" and car was stuck, unmovable, in traffic lane. The emergency brake would not release when put in reverse or drive. The same problem happened again the next day in forward. Two different dealers were not able to duplicate the problem. No warning lights came on.

NHTSA complaint #11729942 — an unverified report by a vehicle owner.
I was pulling into a parking spot and the emergency braking system applied the brakes very forcefully as if a collision was imminent. I backed up and saw nothing in the parking spot and then proceeded to pull back into the same spot with no issue. There was a loud and rhythmic thumping sound that I perceived as the abs system engaging. This is a rental car so I am returning it to the company, National rental car, and swapping out for a new vehicle. I contacted Mazda about this and was given a case # 00434431.
NHTSA complaint #11728337 — an unverified report by a vehicle owner.
I am reporting a potential airbag system/emergency brake failure in my 2023 Mazda CX-50. I was involved in a rear-end motor vehicle accident at approximately 60 mph while my vehicle was completely stopped. I then hit the person in front of me. At the time of the impact, the airbags did not deploy, and I received a dashboard message indicating an airbag system malfunction. Since then, the emergency brake turns on and off on it's own at any time. Due to the severity of the crash, I am concerned that the airbags should have deployed, and their failure raises a serious safety concern. I sustained injuries (multiple fractures) as a result of the collision. I am requesting a formal investigation into possible defect or malfunction in the airbag system and emergency brake system.

I get an error that rear side radar obsured, I activsense temporarily disabled almost everytime I drive at freeway speeds. It disables the blind spot monitoring making the vehicle less safe. It disables for long periods of time in all conditions. Took to Mazda and they indicated it’s an issue, but no solution.

On 1/14/2026, I was pulling into a parking space in a parking garage when the vehicle abruptly accelerated causing the vehicle to hit the concrete wall in front of me. No braking assist or front collision warning issued. Airbags deployed. The car is currently at Joe Myers Collision Center in Houston, Texas to obtain an estimate for repair. The police did not respond to reported incident. Incident was reported to my insurance company immediately.
