2023 Mazda CX-50

1) Climate Control System Malfunction I am reporting a safety-related defect involving the climate control system in my vehicle. Specifically, the temperature control knob is malfunctioning and behaves erratically. When adjusting the temperature, the system does not respond consistently and will unpredictably change temperature settings without corresponding input. This was diagnosed at The Autobarn Mazda of Evanston to be a failure within the HVAC control system. I see it is a common issue discussed in online forums. The issue has been diagnosed and confirmed by a service technician. At this time, the vehicle has not been fully repaired and remains available for inspection upon request. This malfunction creates a potential safety risk because it may cause a distraction while driving. The erratic behavior requires repeated adjustments and attention to the climate control system, diverting focus away from the road. The problem has been reproduced and verified by a dealership technician, who confirmed the abnormal operation of the temperature control knob and system. A repair was recommended, with replacement cost $690.24. The vehicle has been inspected by an authorized dealership, and I also contacted Mazda to request goodwill repair assistance. However, they declined to cover the repair cost. My car has 55,000 miles, but this is an issue that has been present early on if not since day 1. Prior to the failure, there were no consistent warning lights or system messages indicating a problem. Given that this appears to be a known issue with this type of system, I am concerned that other vehicles may be affected by the same defect.

The contact stated he was approaching an intersection when a vehicle in front of him attempted to make a left turn but slowed down. The contact was unable to depress the brake pedal and turned the steering wheel to the left to avoid the crash, but he crashed into the corner of the passenger side rear bumper of the other vehicle. The contact was not sure of the damage to the other vehicle; his vehicle had damage to the right headlight and the front quarter panel. The contact stated that his vehicle was equipped with a front collision avoidance system, but the system had not engaged. The contact stated that no persons were injured. The contact stated that the police were on scene and wrote a report. The vehicle was driven to a collision center for repair. The contact had not had the vehicle diagnosed.

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.

The driver's door is not opening from the inside. To open the driver's door while I am in the vehicle, I have to roll down the window and use the exterior door handle to exit the vehicle. This is a huge safety concern, as the window cannot be rolled down manually. If the car did not have power, I would have to break open the window. The potential for being trapped in the car with this defect is high. Several other owners of this car have reported this: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

The vehicle was not taken to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was 40,585.

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.

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.
