Following a professional brake flush at Roger Beasley Mazda Central in Austin, Texas, the left front brake bleeder screw was left loose. This resulted in a significant loss of brake fluid over several days, causing a 'Brake Warning' light to illuminate and a visible reduction in braking performance. A secondary inspection by an independent mechanic confirmed the screw was not tightened, which caused corrosive fluid to leak onto the wheel and compromised the safety of the vehicle.

I am reporting a potential safety-related defect involving premature axle failure on Mazda CX-50 vehicles. The axle appears to be prone to early failure under normal driving conditions, sometimes at relatively low mileage. There are multiple reports from other Mazda CX-50 owners describing similar axle or CV axle failures, including clicking noises, vibration, loss of power to the wheels, and complete axle failure. These reports are publicly documented on online owner forums and Reddit, suggesting a pattern rather than isolated incidents. Axle failure can result in sudden loss of propulsion and may increase the risk of a crash, especially at highway speeds or during turns. This appears to be a design or durability issue rather than normal wear and tear. I am concerned this defect affects multiple vehicles and warrants investigation and a potential recall before more failures occur.

I brought my vehicle to Safford Mazda of Fredericksburg on Monday, December 15, 2025 due to a front-end clunking that occurs during left or right turns. A service representative test-drove the vehicle with me and was able to hear and duplicate the noise. Shortly afterward, I was informed that the front axle has internal damage and that the vehicle would need to be retained by the dealership for repair. I was told the necessary parts would not be available until sometime in February 2026. The dealership retained possession of the vehicle and arranged a loaner vehicle for my use. The service manager declined to provide written documentation stating that the car was unsafe to drive or describing potential consequences of continued operation. However, the vehicle was not released back to me pending the axle replacement. I have filed a complaint with Mazda Corporate, documenting the issue and the dealership's findings. A Mazda corporate case number is available if needed.

First time I noticed the crack on top passenger side of the windshield was on 9/12/25 while taking a break from work in my car. Car mileage on 9/12/25 was 1892 miles Upon inspection of windshield, I found out that crack was felt when I ran my fingernail on the inside, and when trying to feel the crack from the outside, windshield felt smooth and without any indication of cracking. I would like to attest that this vehicle has been kept in a garage since its purchase. I also would like to add that there has not been debris of any kind hitting the windshield while driving it, hence the crack being felt only from the inside. I have taken the car to the dealership today and I have an appointment for further inspection on 9/24/25

The vehicle had the original OEM battery fail at 15 months. It dropped to 7v under light load. It's a bad battery. Upon being jump started, the power steering went in and out while driving and the dashboard blinked on and off...throwing a lot of errors that are unrelated to the battery problem. The failure state of the vehicle with a bad battery is unlike any vehicle I have ever seen and it is extremely dangerous. Furthermore, Mazda roadside assistance does not know about this issue and only offers jumpstarts, putting customers into danger by suggesting that the vehicle is safe to drive with a battery that is not stable.

I was driving to Castle Rock, CO from Parkville, MO on [XXX] for vacation. I used the heated seat feature off and on during the trip. When I arrived in CO at my destination I noticed my thighs were hurting- stinging and hot. I checked my thighs and saw they were red and blisters were forming. I went to urgent care and I referred to the ER- I was given information about how to treat 2nd/3rd degree burns.

Wear of Strut Bearing causing crunching sounds at low speed braking and turning. Dealer reports this is due to dirt and debris getting up there. Vehicle has 34,000 miles (out of warranty due to time) and has had only light use off-road on dirt roads (2 camping trips). Not repairing can cause further damage and failure of suspension components. Vehicle marketed as off-road capable but components not protected properly from dirt/debris from driving off-road.

I have had my 2023 Mazda CX-50 for almost two years. Since I got the car, I have had no issues with the i-Activsense until June 2025. The reason I got the newer car was to ensure the safety of my family; however, Mazda failed to do their part. My car was recently involved in a car accident due to a faulty system. It appears that the newer Mazda CX-50s were included in a recall, but the 2023 model was not and it should be. On the day of the accident, my daughter was driving my car. The traffic was slowing down, and two lanes of traffic had to merge to one lane due to construction and all of a sudden, the car in front of her slammed on their breaks and the car could not stop in time before hitting them. My car never sent an alert until contact was made with the other car, and the emergency breaking did not activate. After my car hit the other car, an alert came on screen that indicated the i-Activsense was disabled. Once the car was turned off and then back on the alert disappeared. Additionally, I am now having issues with the rear camera not alerting if someone is behind me (car or pedestrian). I have a 2019 Jeep Grand Cherokee that will slam on the break for you if you get too close to an object when you are in reverse. Isn't that what the Mazda CX-50 should be doing?

On [XXX], our 2023 Mazda CX-50 experienced a failure of the control arm, which was confirmed by Auffenberg Mazda of O’Fallon, IL, to be a manufacturer’s defect. Despite this, the dealer informed us that the vehicle was safe to drive. However, Mazda corporate contradicted this, stating the vehicle is unsafe to drive and instructed us not to operate it. We were informed that the replacement part will not be available until sometime in July 2025, leaving us without a safe vehicle for nearly two months. Both Mazda corporate and Auffenberg Mazda of O’Fallon, IL, have refused to provide a loaner vehicle or commit to reimbursing rental car expenses during this period. Additionally, Mazda corporate has failed to maintain consistent communication, not returning calls when promised and leaving us without timely updates or resolution. This situation poses a significant safety concern and financial burden, as we are left without a reliable means of transportation due to a confirmed manufacturing defect. We request that the NHTSA investigate this issue, including the conflicting safety assessments provided by the dealer and Mazda corporate, the delay in part availability, and the refusal to provide a loaner vehicle or rental car reimbursement. We also urge an evaluation of the control arm defect to ensure other Mazda CX-50 owners are not at risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
