On several occasions, moving the gear selector from Reverse to Drive, the transmission has failed to engage Drive, with the dashboard displaying "D" and the vehicle moving in reverse upon throttle application. Fortunately, objects, pets or pedestrians were not present behind the vehicle during the occurrences. The dealership was unable to duplicate the condition and found no software updates or other notices from Mazda addressing the issue.

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.

The contact's daughter owns a 2026 Mazda CX-50. The contact stated that while his daughter was driving 40 MPH and decelerating to turn into a parking lot, the front passenger’s side wheel detached and fell in underneath the vehicle. The vehicle was towed to a tow yard and was then towed to the dealer. The dealer stated that the failure was due to a crash and informed the owner that the repair was not covered under warranty; however, the contact stated that a Police Officer confirmed that there was no damage to the curb or in the vicinity of the vehicle during the failure. No diagnostic information was available. Upon inspection by an insurance adjuster, it was determined that the repair would be covered by the insurance company and would be performed using aftermarket parts. The parts were unavailable, and the vehicle was not repaired. The manufacturer was notified of the failure and assisted in locating a dealer. The failure mileage was approximately 3,506.

Component: Air Bags – Knee Airbag / Trim Panel During a collision, on July 3rd with the Mazda CX‑50, the knee airbag deployed and a hard plastic trim panel from the lower dashboard was forcibly ejected. This panel struck my knee and caused a laceration across my kneecap. The injury was not caused by the crash itself but directly by the detached interior component. The trim panel appears to be part of the knee‑airbag assembly and should not detach with enough force or sharpness to cause bodily harm. I experience pain, discomfort, and ongoing issues due to the injury with tingling down my left leg when I get up to walk. I am concerned this represents a design or manufacturing defect in the knee‑airbag trim panel or its breakaway mechanism. Photos of the deployed airbag, the detached part, and the injury are available.

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.
