2025 Mazda CX-30 problems

Filed Sep 7, 2026 · Electrical, Engine · FL

I am writing regarding my 2025 Mazda CX-30, purchased brand new with 0 miles on [XXX]. The vehicle currently has 22,000 miles. I am extremely concerned about the reliability and, most importantly, the SAFETY of this vehicle. August 29, 2025: I brought the vehicle to the dealership after receiving a recall notice. My service slip states only “performed Software update,” with no details regarding the recall. Refers something about the engine being left on over 2 hours will loose power. Mileage was 9,650. [XXX]: The check engine light came on. I was told the vehicle was leaking oil and that it was not a major concern per a 20+year old technician. The dealership replaced the REP Tensioner Belt. [XXX]: While driving on [XXX] on my way to [XXX], my vehicle SUDDENLY LOST POWER AND DIED WHILE I WAS DRIVING. This was an EXTREMELY SERIOUS AND POTENTIALLY LIFE-THREATENING SAFETY INCIDENT. Thankfully, I had not yet entered [XXX] and was not hit by another vehicle. Had my vehicle suddenly died after entering [XXX], I truly believe the outcome could have been catastrophic or fatal. I DO NOT FEEL SAFE DRIVING THIS VEHICLE! I cannot trust a vehicle that unexpectedly loses power and dies while being operated. This incident has completely destroyed my confidence in the safety and reliability of my Mazda. I am formally requesting that Mazda immediately open and begin the Florida Lemon Law/warranty process, thoroughly investigate the cause of this dangerous loss of power, and provide me with a written explanation of what caused the vehicle to die and whether it is safe to operate. Please treat this as an URGENT SAFETY CONCERN and provide an immediate response. Thank you.

The wiper settings cannot be adjusted every speed is high- (meaning, the wipers always go super fast) unless, its on auto. I dont alwaus want to use auto. My dealership tech now has "refused" to work with me anymore- or has encouraged me to find another dealership bc of all the random little things ive brought up aboht the car. Seems to frustrate him. Just 2 days ago- the car started leaking water thru the top of the liftgate when going through the car wash. (I do opt for touchless- btw)

2025 Mazda CX-30 experienced a sudden complete loss of power while driving at highway speed with no prior warning lights or indications of malfunction. Immediately before shutdown, steering became extremely stiff due to loss of power steering assist. Vehicle was steered towards the shoulder during highway speed of 65mph and was electrically inoperable while rolling, this includes the loss of hazards, power steering and electronic brake lock engagement.

On multiple occasions while driving in rain/snow/ice, the vehicle will initially throw an "i-ACTIVESENSE Partially Disabled Due to Camera Malfunction" error. This initially disables adaptive cruise control, lane keeping, blind spot detection, etc. This error immediately then cascades to throw a "Dynamic Stability Control Malfunction" error as well as an "ABS Malfunction" error, suggesting that both dynamic stability control and ABS are disabled. This issue has occurred roughly 50% of the time it rains/snows, and usually persists for 1-2 days even after fully clearing the windshield where the front camera system is located. This has caused me to have to drive the vehicle several times now in the rain and snow without ABS and dynamic stability control active -- this is a serious safety issue. It is understandable for a front camera malfunction to disable sensing features (like lane keeping), but this should not disable necessary safety features such as ABS and stability control. It is clear that there is a cascading sensor malfunction in this vehicle (possibly related to an earlier similar recall in 2024 models), that causes serious safety concerns.

The vehicle has major electrical issues. The ABS and all over driver safety options would shut off for days at a time. I had purchased this cx30 as new on January 02, 2026. It totally died and wouldn't start on February 03, 2026. It had to ve towed by mazda roadside assistance to Towne Mazda dealer in Orchard Park NY. It is now March 12, 2026 and the dealer has had my vehicle for over a month. They put a new wiring harness in it ans other components. Very frustrating.

While driving on the highway our sunroof exploded with no impact. The glass blew up outwards causing a loud gunshot like sound. We had the sunroof closed (not in use) and there were no vehicles around us for any asphalt or rocks to cause impact.

I have been having repeated issues with the doors not autolocking, liftgate functionality, rear seat sensor, and random (collision?) warnings/sensors - among other settings that keep coming undone (audio options, etc) since the purchase of this car that I have been diligently notating/timestamping- i have close to 200 occurences so far. Just submitting another report to let you know it is STILL happening and IS NOT user error.
