2025 Mazda CX-30 Problems

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.

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 contact owns a 2025 Mazda CX-30. The contact stated that while driving at approximately 2 mph into his garage, his right foot had slipped between the brake pedal and the accelerator pedal, and he was unable to get his foot out from under the pedals. The contact stated that the front end of his vehicle crashed into his garage wall. The contact stated that there was some damage to the front grill and the hood of the vehicle. The contact stated that he had not taken the vehicle to a dealer or collision shop. 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.

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.

Car is forecasted to get 290 miles off a full tank after doing nothing but highway driving. 10 miles less than when I first drove it (off the lot and primary highway driving) and 60 miles less than it should according to Mazda statement of 21-30mpg.

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)

Although im confident in my own driving skills, it concerns me that the blind spots are so bad that it is NECESSARY to use the blind spot warning system and reverse/back up camera.

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.

I have noticed over 30 things wrong with this car. Including but not limited to- the FIRST THINGS I mentioned to the dealership there seems to be apull to the right (suspension/alignment). The car randomly starts driving or feeling 'jerky" as if cruise control has taken over - 'phantom braking' is a term I came across that sounds accurate to me. And now, after having the vehicle for almost 30 days- there is significantly less mpg.received. 300 first tank vs about 250 this current tank.

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.

I wondered if, after my first service visit on 11-12-25, the dealership put regular leaded gas instead of premium in it, because there was a noticeable difference in gas mileage and the engine started revving pretty high, in my opinion. It also seemed to have less power (which was my main reason foe thinking the wrong gas had been out in). And since then, it hasn't been the same.

At an unspecified service visit I Was told tires were at manufacturers recommended psi YESTERDAY - left the lot at 1530. The next morning - warning system indicated low psi- even as low as 30psi and front passenger so low it did not give a reading??? I have no idea why a service visit was even recommended at 1000 miles. Intake rep said for manufacturer oil change and maintenance?! 1000 miles? Bought 11-8-25?! So, if service visits are directly tied to software communication of the vehicle then, thats being reported too.
