   Fuel gauge permanently stuck on empty. Computer code = P0463 Occurred on Jan 30, 2026. Mechanic provided error code at that time. Unsafe driving conditions where distance-to-empty calculations are disabled, standard fuel level indicator showing empty (or stuck on full) risking an unexpected engine stall on public highways and roads. I have NO idea how much Fuel is in the tank nor how many miles are left on tank which could lead to unexpected and sudden stops in high traffic situations. Yes: code was confirmed by Advanced Auto, London Motorworks, and personal computer. Fuel sensor stuck on "FULL" in May 18 then again stuck on empty since May 21. Vehicle inspected by mechanic on Jan 30, 2026 Engine Warning light began on Jan 30, 2026 at 9:22amCT

   On multiple occasions the vehicle has not acceleratedfrom a stop while pushing the accelerator pedal. Have noticed this is usually on warmer days, with AC on half to full, within 3 minutes, and within 1 mile from leaving work for the day after car has sat parked. I am worried this will get worse and cause a potentially dangerous situation when turning left against traffic and the car doesn't accelerate.

   While driving 72mph on the interstate at 6am on 7/21/26 the sunroof exploded. No foreign objects made impact with the vehicle and there was no sudden temperature shifts. The glass had no previous defects and it shattered into tiny pieces, failing into the car. The sun shade was open at the time. The vehicle is being serviced at a glass repair shop who noted this is a common issue with Mazda sunroofs.

7. Filed May 29, 2026Failure May 29, 2026Gastonia, NCElectrical system

   The temperature control dial on the climate control system behaves erratically and inconsistently. When turning the dial to increase temperature, the displayed temperature sometimes decreases. When turning it to decrease, it sometimes increases. The dial also jumps multiple units rather than incrementing one degree at a time. The behavior is unpredictable and occurs regardless of whether the engine is warm or cold. This issue has been confirmed by multiple other 2023 CX-50 owners in owner forums, suggesting a manufacturing defect in the encoder mechanism for the temperature control knob. The dealer confirmed the bumper-to-bumper warranty has expired but has not offered a resolution.

8. Filed May 15, 2026Failure Feb 1, 2026Reynoldsburg, OHElectrical system

   When adjusting the temperature in the car with the dial, it does not respond correctly. It either jumps up or down by multiple degrees. This causes to take your eyes off the road to try to adjust the temperature. No warning lights came on and pushing lighter or harder on the dial does NOT fix it. Only driver side is currently having this issue.

   2023 Mazda cx50 has a leaking panoramic sunroof and was noticed on February 27th, 2026 after a hard rain. Got an appointment with my dealership on March 4th, 2026 I bought my car through, they denied helping me of any kind and diagnosed my car with a cracked sunroof bypass drain plug and the part can’t be replaced, the entire panoramic assembly needs to be replaced. I believe this is a safety issue and Mazda Corporate will not help either. Water should not be coming into my car with electronics at risk!

    Transmission Malfunction / Erratic Low-Speed Operation I am reporting a safety-related defect involving the transmission system in my vehicle. The issue appears to have originated as a software-related drivability problem but progressed over time into a more serious mechanical failure affecting the transmission. The vehicle exhibited lurching/hesitation at low speeds, particularly during city driving and while idling or creeping forward in traffic. This malfunction creates a potential safety risk because the vehicle does not respond smoothly or predictably to driver input. The erratic behavior is disconcerting and requires increased driver attention, creating a distraction and reducing confidence in the vehicle’s operation. The issue has been reproduced and confirmed by a service technician, who identified a transmission-related problem and recommended repair or replacement. The failure was not consistent with normal wear and occurred prematurely. The vehicle has been inspected by an authorized dealership and is covered under the 5 year power-train warranty. Prior to the failure, there were no warning lights or messages indicating a major transmission issue. The problem I believe has been there since day 1- initially presenting as mild hesitation that could be mistaken for normal operation (especially with a turbocharged engine), but became increasingly annoying over time. After researching the issue, found similar reports from other owners describing comparable transmission behavior, suggesting this may be a broader defect.

    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.

    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.

    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.

    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.
