What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The contact had called the manufacturer and was advised that there was no action that could be taken to adjust the distance separating the brake pedal from the accelerator pedal. The contact stated that his foot had been trapped on two other occasions. The failure mileage was approximately 700.
[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 20year 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.
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…
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.
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.
It totally died and wouldn't start on February 03, 2026. It had to ve towed by mazda roadside assistance to [dealer] 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 tire pressure has also been varying quite a bit with inconsistent levels across all tires since purchase over the past 3 months.
Tire psi seems to vary greatly under mild conditions. Drove 10 miles- city. 40mph. 70 degree weather. Increased 3psi.
