2026 Mazda CX-50 owner complaints

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 was backing out of a parking spot in a parking lot that backed up to a 2 lane highway. I placed the car in Reverse and then put the car in Drive, so that I could exit the parking lot to a side road. When I placed the car in Drive and pressed gas, the car went into Reverse (towards the 2 lane highway behind me). I placed the car in park, then back to Drive, it went in Reverse again. We were now in the 2 lane highway with oncoming traffic swerving to avoid us. We decided to put the car in park and turn off the car. Then, we restarted and place the car in Drive. It went into drive and we moved forward into the parking lot, off the highway and then we could exit the parking lot and drive home.

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,

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.

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, a

This report concerns the design of the front seat belt reminder system, which I believe creates a safety hazard. The audible warning begins the instant the engine starts — while the vehicle is stationary in Park — is very loud, and repeats indefinitely until the belt is latched. Federal Standard No. 208 requires only a short warning (up to 8 seconds); this immediate, persistent chime is a voluntary design choice. Other manufacturers (e.g., Honda) meet the same standard while chiming only once the vehicle is in motion, which is sufficient and far less intrusive. The safety problem: because the warning is so aggravating, owners are defeating their own seat belt systems. Owners across the Mazda lineup — CX-5, CX-30, CX-50, CX-90, Mazda3, and Mazda6 — publicly document this on owner forums (

At approximately 2,900 miles, during the first oil change/service, the factory-installed spin-on oil filter could not be removed normally. The oil filter required approximately one hour of removal effort and would not spin off in a normal manner. When the filter was finally removed, the oil filter threaded adapter/union came out of the engine-side oil filter housing while still seized inside the oil filter. The adapter threads showed visible damage, including flattened, galled, and torn thread areas. The oil filter was seized tightly enough to the adapter that the oil filter had to be cut away from the adapter to separate the parts. The adapter was removed from the filter without adding further damage. The damaged adapter threads were cleaned/chased only as a temporary repair because the v

We are having concerning issue with Mazda CX 50, 2026 hybrid. not going into reverse gear or stopping unexpectedly after attempting to shift to reverse. We recently took the vehicle to the Mazda dealership where we bought it.: Luther Mazda in [XXX]. After repeated attempts, they said they had no way to address the problem since they couldn’t re-create it. We reiterated that it just happened several times to us, but we cannot re-create it on demand. I sent the dealership the following information from the Internet, that was posted about the 2025 model having the same issue as our new 2026 is having.
