2025 Mazda CX-30 electrical 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.

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.

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.

The contact owns a 2025 Mazda CX-30. The contact stated that the key fob had a slight dent, and after dropping the key fob, the key fob fractured into several pieces. The contact was unable to lock and unlock the vehicle using the key fob. The dealer was contacted and informed of the failure. The dealer advised the contact to purchase a new key fob. The key fob was not replaced. The manufacturer was made aware of the failure. The contact’s spouse's key fob had a similar failure, even though there was no dent in the key fob before the failure. The contact saw many online forums with the same defect. The manufacturer referred the contact to the federal safety agency Hotline to report the failure. The failure mileage was unknown.

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.

It seems like the computer has defaulted to receive the lowest possible gas mileage- if this is somehow communicating with the fuel system- its definitely affecting how much mileage I could be getting and robbing me of up to 100 miles per tank.

Iactive sensor indicated there was a/n (obstruction) or something preventing iactive from working (i dont remember what it said)? I dont remember- but either way- i find it distracting. It could not be turned off and was flashing repeatedly- telling me to drive safely ironically making me feel like I had to read it, in inclement weather, and take my eyes off the road.
