2025 Mazda CX-50 Owner Complaints

"My 2025 Mazda CX-50 began overheating while still under the factory warranty. During one incident, the engine lost coolant and overheated. I immediately shut the engine off to prevent damage. The vehicle continues to overheat, and the air conditioning only cools properly while the vehicle is moving. When stopped or idling, the A/C stops cooling. I have reported the issue to my Mazda dealer and opened Mazda Customer Experience Case Number 00473077. The problem remains unresolved despite multiple attempts to obtain assistance. I am concerned this condition presents a safety risk." "The vehicle has been inspected by an authorized Mazda dealership on two separate occasions. The dealership kept the vehicle for several days during these inspections but reported that it could not reproduce or identify the cause of the overheating. Despite these inspections, the overheating condition and the air conditioning issue continue. During one of the service visits, I also discovered scratches to the vehicle's exterior that were not present before it was left with the dealership."

While driving my 2025 Mazda CX-50, the entire center-dash climate control panel (HVAC module) suffered a sudden, spontaneous, and total electrical power blackout. The unit completely loses power and goes dark exactly as if the power button was pressed. This is a recurring failure that occurs after only a few minutes of vehicle operation. This electrical failure immediately cuts all airflow and A/C cooling to the cabin. The unit can temporarily be turned back on manually, only to black out and fail completely again minutes later. This represents my second consecutive modern Mazda vehicle to experience an early-mileage HVAC hardware/electrical failure (previously a CX-30), indicating a dangerous, recurring manufacturing defect in Mazda’s electrical/climate control architecture that requires a formal safety recall. Additional Considerations: Distraction and Loss of Driver Focus, Rapid Window Fogging and Blindness, Extreme Heat Exhaustion and In-Cabin Medical Emergency, and Broader Electrical Fault Concerns.

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.

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

Incident

May 22, 2026

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)

Stopped at a convenience store in [XXX] . Upon return to vehicle, it would not start. A check engine light and steering alert came on. According to ChatGPT it appeared to be an electrical problem. AI recommended that the vehicle be "rebooted". That entailed putting the car in Park, turning the ignition off, turning off all accessories, getting out of the car, locking it with the FOB, and walking away from the car with the FOB. Don't return until after 5 minutes or more. The second incident occurred on the out skirts of [XXX] . The instrument panel went dark for a half a second or so. Once it became illuminated, another warning alert appeared: Telematics Communication Unit Malfunctioned. AI suggest not turning ignition off until we reached our final distination. Have a dealer run a diagnostic scan on the voltage system. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Door handle cables detach easily which prevents the door from being opened from the inside. It has happened to me twice on my driver side door the last 5 months. Research online shows this is a very common problem with newer Mazdas and it is a major safety hazard as it prevents easy exit from the vehicle in the event of an emergency, especially if there is power loss so the windows cannot be opened.

Mar 31, 2026

I am reporting a potential safety-related defect in my 2025 Mazda CX-50 Preferred, which is approximately four months old. On one occasion, the vehicle moved backward while in Drive mode. This occurred twice on the same day under similar conditions on a slight incline. After starting the vehicle, I shifted into Drive and applied acceleration; however, the vehicle moved backward instead of forward. The rearward motion continued despite active acceleration input. This behavior is not consistent with normal rollback on an incline. The continued backward movement under acceleration indicates a possible issue with transmission engagement, gear recognition, or electronic control systems. I reported the issue to an authorized Mazda dealer. I was informed that shifting the gear too quickly may cause a delay in system response, resulting in the vehicle behaving as though still in Reverse. I consider this explanation unacceptable for a modern automatic vehicle and indicative of a potential defect. This condition presents a safety risk. Unintended rearward movement while in Drive could lead to collisions, especially in situations involving other vehicles, pedestrians, or objects behind the vehicle. Although the issue has not reoccurred since that day, the intermittent nature raises concern about reliability and the potential for recurrence without warning. I request that this issue be investigated as a potential safety defect.

After about six months of ownership, a knocking noise started happening from the front of the vehicle when turning the wheel all of the way to the right. A month or so later I brought it to a Mazda dealership in Green Brook, NJ. I was told by the service advisor that she had the same vehicle and was advised that this was normal. She explained everything exactly as I had experienced it. She told me I could wait in the dealership for 3/4 hours, but the technicians would most likely just tell me the same. Over time, the suspension deteriorated. Bumps felt more and more noticeable and a lot of noise inside the cabin. Specifically, a lot of vibrating on the right side of the vehicle: windows, front passenger seat, and the trunk window. Looking over the internet, it seems like this problem is apparent in multiple vehicle years, but never properly addressed via a recall: [XXX] . The vehicle is currently in Sansone Mazda in [XXX] . They replaced the right CV and the problem did not go away. I was told they would have to contact Mazda corporate. They did and I was then advised that they would need to replace the left CV axel, as well. Not surprisingly based on the frequency of this issue, that part was unavailable and on back order. I don't know how long I'll be without my car at this point. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The tire on the front driver's side was bad. I had it assessed at Ogeen K auto and he said they put a used tire on the vehicle. The other three were brand new. The noise I was hearing was coming from the tire. And was causing the vehicle to pull. My safety was put at risk because Iwouldd need a longer stopping distance. Sliding, the vehicle pulling to one side, and the spare tire was missing. They covered the hole with a piece of cardboard. I spoke to the employee at Hertz and told him the day he gave me the vehicle. There were no lights or warning lamps on.

Incident

Jan 31, 2026

At only about 6,100 miles and during my vehicle’s first service, the technician found grease leaking from the left front CV boot. The dealer stated this was caused by an external puncture, but they were unable to provide clear evidence, detailed photos, or a written diagnosis proving that the damage was external. The mark they referenced was extremely small and not consistent with a clear impact. A CV boot should not fail at such low mileage, which raises concerns about a potential early-life component failure or material defect. A torn CV boot can lead to CV joint wear, loss of power, or loss of vehicle control if it progresses. Because the root cause is uncertain and the failure occurred unusually early in the vehicle’s life, I am reporting this to NHTSA in case this represents a broader quality or safety issue affecting other vehicles of the same model.

Vehicle: 2025 Mazda CX-50 Hybrid Mileage at first failure: ~6,000 miles Component: Front CV boot / axle assembly — loss of grease Safety Concern: Early-life component failure with unresolved uncertainty in root cause Description: At approximately 6,000 miles, the left front CV boot of my vehicle was found leaking grease. The dealership initially stated the failure was due to “external impact,” but no conclusive evidence was presented to support this determination. The photos and inspection notes did not identify a clear puncture or specific point of impact. Mazda Corporate later informed me that their engineering team concluded the issue was not related to a material or manufacturing defect, and offered a goodwill repair. However, the underlying root cause remains uncertain due to the lack of definitive evidence. Safety relevance: A CV boot failure at such low mileage is extremely unusual for a modern vehicle, and premature loss of grease from the CV joint can lead to: joint degradation, reduced steering stability, potential loss of vehicle control. If similar early-life failures occur on additional Mazda vehicles, this may indicate a broader design, material, or assembly concern. Requested Action: I am submitting this report for documentation purposes in case a pattern emerges or if the issue recurs on my vehicle or others.
