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 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. 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. [XXX] "[XXX]" Livingston INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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.

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 NHTSA Hotline to report the failure. The failure mileage was unknown.
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.

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.
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.
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.
At 1833 yesterday evening, the doors did not autolock.
It 1833 the doors did not autolock
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.
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.
Warning sensors activate randomly- of oncoming vehicles- in my opinion for no reason. Enough space between cars. Normal speeds, etc. Warning sensor to engage Brakes activate without sufficient reason. More than enough space between cars, normal speeds. Occasionally, it feels as if cruise control has taken over and slows the car down (not braking exactly, but controlling the speed by decreasing it). Acceleration also seems to randomly be controlled in the same manner.
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.
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 basics
How to read this data
Complaints, recalls, investigations — here’s what each number actually tells you about a used Mazda CX 30, in plain English.
What is an NHTSA Complaint?
An NHTSA safety complaint is a report filed directly by a vehicle owner or driver describing a safety-related issue. Anyone can submit a complaint at NHTSA.gov. The number of complaints is a signal of how common a problem is — but complaints per model-year matter more than raw totals, since popular vehicles naturally receive more reports. The Mazda CX 30 has 253 complaints on record across 7 model years.
What is a Safety Recall?
A safety recall is a mandatory campaign issued by NHTSA when a vehicle component poses an unreasonable risk to safety or does not comply with federal motor vehicle safety standards. Unlike complaints (which are owner-reported), recalls are formally investigated and confirmed by regulators. Manufacturers must fix recalled vehicles free of charge. The Mazda CX 30 has 10 recall campaigns in the NHTSA database.
What Are Crash Complaints?
Crash complaints are NHTSA filings where the owner indicates a crash occurred as part of the incident. 25 of the Mazda CX 30's 253 complaints involved a crash. This metric is particularly important because it indicates how often defects resulted in actual collisions — a key safety signal beyond general reliability.
How Is the Reliability Verdict Calculated?
The reliability verdict (Poor) is generated by analyzing the vehicle's total complaints, recall history, crash complaint ratio, fire complaint ratio, and top component failures relative to class averages. This verdict gives buyers a quick interpretation before they review year-level details and VIN-level history. It should be treated as one decision input, not a substitute for a VIN-specific report.
Why Do Newer Years Have Fewer Complaints?
Newer model years appear to have fewer complaints because there has been less time for owners to file them. Complaints accumulate over years of ownership. A 2020 model year vehicle will typically show fewer complaints than a 2015 model year even if it is less reliable — simply because fewer owners have had time to report issues. Focus on complaints per year of market presence when comparing across model years.
Fleet Data vs. Individual VIN
Everything on this page reflects aggregated data across all Mazda CX 30 vehicles on the road — not any specific car. Two Mazda CX 30 vehicles of the same year can have very different histories: one may have been in three accidents and have an open recall; another may be clean. A VIN check gives you the individual car's history: accidents, title brands, odometer records, service history, and real-time recall status.
What Are NHTSA Investigations?
When NHTSA receives a pattern of related safety complaints, it opens a formal investigation. A Preliminary Evaluation (PE) is the first stage — NHTSA determines if a safety defect may exist. If evidence is strong, it escalates to an Engineering Analysis (EA), which can result in a mandatory recall. The Mazda CX 30 has 0 investigations on record (0 active). Investigations listed above may have already led to the recalls shown on this page.
