2024 Mazda CX-30

The vehicle intermittently fails to start when pressing the push-button start system. The start/stop button becomes unresponsive despite normal conditions (key present, brake engaged, no warning indicators preventing ignition). This has now occurred twice within two years of ownership, indicating a recurring issue rather than an isolated incident. On the most recent occurrence, the vehicle was completely unable to start and required towing. The tow truck operator reported that he had towed four vehicles of the same make/model for the exact same issue within one week, suggesting a broader pattern affecting multiple vehicles. Safety Concern: This presents a significant safety risk, including: •Inability to start the vehicle in unsafe or emergency situations •Risk of being stranded in dangerous environments (e.g., roadside, extreme weather, unsafe areas) •Potential failure of the ignition system, which raises concerns about reliability of vehicle operation overall A malfunction in the start/stop system directly impacts the vehicle’s basic functionality and creates an unpredictable and potentially hazardous situation for drivers. Additional Notes: Given the repeated occurrence and reports of similar failures in other identical vehicles, this issue may represent a systemic defect that warrants investigation.

I was driving down the Highway and the sun roof just exploded send shards of glass everywhere and nothing had hit it or anything. It just exploded. When I got to the dealer the person ahead of me had the exact same thing and we compared pictures. It was scary, dangerous and really loud when it happened.

I was sold this 2024 Mazda cx30 from Ken ganley kia located in mentor Ohio (44060) the vehicle started showing major electrical issues. when they occur I have no control of the functions of anything in the cabin (infotainment, heat/air, braking system,) just to name a few. My wife and I were assured we were purchasing a good safe and reliable used vehicle. I feel this vehicle is extremely unsafe and unpredictable and ken ganley kia of mentor refuse to take this unsafe vehicle back or even pay for the repairs. I am utterly disappointed such a big name in the auto industry could turn there back on a customer not only that let a young family pull off in a unpredictable electrical nightmare of a vehicle and refuse to stand by it.

I had both the left front and right front CV axles fail. My car only has 11.5k miles on. I first heard the clunking noise at 11k miles, went right to the dealer and had them watch me recreate the noise and they determined the axles needed to be replaced. This is incredible dangerous as the CV axle could have been completely disconnected from the wheel assembly leaving my car useless and uncontrollable.

The contact rented a 2024 Mazda CX-30. The contact stated that while driving at highway speeds, an "i-ACTIVSENSE Partially Disabled Front Radar Malfunction" warning message appeared on the instrument panel. The contact attempted to exit the highway; however, the vehicle failed to stop upon depression of the brake pedal. The contact continued to pump the brakes and even engaged the emergency brakes, but the vehicle failed to stop. Due to the failure, the contact crashed into the vehicle in front of her as the "Vehicle System Malfunction, Have the Vehicle Inspected" warning message appeared on the instrument panel. The air bags did not deploy upon impact. The contact later sought medical attention for pain in her back; the other driver sustained injuries; however, the injuries are unknown as she did not seek medical attention from the paramedics that arrived at the scene. A police report was filed. The vehicle was towed from the scene to an independent mechanic, where it remained in their possession. Neither the dealer nor the manufacturer had yet been notified of the failure. The vehicle was not repaired. The failure mileage was 38.377.

Cruise control and lane keeping system engaged. Vehicle will occasionally aggressively apply brakes, when nothing visible is in front of the vehicle. This has nearly cause our car to be rear ended on a number of occasions. I suspect the system mistakenly interprets a building or vehicle shadow as a physical object. This response has also occurred when vehicle in front (cruise control distance at slower speed) turns right. Again, nearly causing vehicle behind to be rear ended.

Component/System: Automatic transmission (requires full replacement). The vehicle is currently located at Safford Mazda of Fredericksburg, 10653 Patriot Hwy, Fredericksburg, VA, 22408, and is available for inspection upon request. Safety risk: The transmission developed a loud whining and grinding noise while driving, indicating imminent risk of sudden loss of motive power or seizure. This creates a severe crash hazard, especially on highways or during acceleration/merging. Sudden loss of propulsion without warning can leave the driver unable to accelerate, maintain speed, or move out of harm’s way. The problem has been reproduced and confirmed by Safford Mazda (authorized Mazda dealer). On October 16, 2025, they diagnosed the vehicle as requiring a complete transmission replacement (Repair Order/Multi-Point Inspection Video is available). The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives, but remains at the dealership awaiting parts. Starting approximately in late August, a transmission whine started zero warning lights or alerts ever appearing. Noise rapidly worsened. [XXX]: expert friend drove it once, instantly recognized imminent failure, and ordered me to stop driving immediately. At ~20,000 miles, the dealer confirmed the drive unit must be fully replaced, still with no dashboard warning ever triggered. Had I kept driving while trusting the silent system, this critical component could have seized at any moment, causing sudden total loss of propulsion at highway speed or in traffic with my young child on board. The complete absence of any alert during a proven, progressive failure is an urgent, unacceptable safety defect that demands immediate investigation and recall before a family is injured or killed. As of [XXX] , the vehicle has been out of service for 33+ calendar days. The dealer informed me I am #60 in Mazda’s national transmission replacement backlog.

While driving normally at highway speed on I-880 South, the braking system failed to decelerate the vehicle. When the brake pedal was pressed firmly, there was no normal slowing—only a sliding sensation, as if the wheels locked and the car moved forward on ice. This led to a collision with a stopped vehicle ahead. The following day, the Mazda App displayed a red alert message: “Brake system malfunction. Braking effectiveness may be decreased.” The vehicle’s airbags deployed very forcefully, causing bruising to both driver and passenger, even though the impact was not severe. Three days before the incident, the vehicle had a scheduled maintenance and recall service at a Mazda dealer, including a brake inspection and air-bag recall repair. The vehicle was declared a total loss by the insurance company and is currently stored at Copart Hayward, CA. The problem has not been inspected by Mazda yet, but a formal safety review is requested. The issue posed serious safety risks due to total loss of braking control and unexpected air-bag deployment.

On [XXX] autoNation Mazda Arapahoe in Colorado sold me a car for my sign at 2024 CX 30 premium. They said there was an open recall that they needed to fix and we’re keeping the car overnight on June 6, 2025. They deliver the vehicle to my son around noon and around 6 PM on June 6. They contacted my son and said they shouldn’t have sold the vehicle to him and needed the vehicle back. This is my son‘s first vehicle and it’s not a good experience and the dealership should never have sold that car to us knowing that there was not a fix. They were well aware of this on May 29.

I have received a recall notice back in June 5th. I tried to reach my dealer (Douglas Mazda) couple of times but they are not fixing it. As it has been announced that, it is not available. The vehicle is under warranty. PLease suggest me what steps I should take? As it is not not safe drive in any highway.

The sunroof exploded. Was no external debris or damage. Glass pushed outwards. 47 degrees outside. Very sudden and scary.

Wife was driving 2024 Mazda CX-30 with (bought demo from dealer in February with 2500 miles on it and now 4006 miles) daughter ([XXX]) in passenger seat. Airbag deployed with no warning or malfunction lights or alerts prior. Knocked my daughter across the vehicle, startled and traumatized both of them. They were able to safely pull into a shopping center parking lot. Got vehicle towed to the dealer, John Kennedy Mazda in Pottstown PA. Called police--have report and pictures to document. Wife also has videos and pictures. The dealer provided us a loaner vehicle. Next day the service manager, Gary Daniels calls. I ask if he has ever seen this before. "I think I know what caused it. There was a bubble in the right front passenger tire." I responded that I saw how this was going and told him I will be in touch. Dealer not covering it under warranty and said "call our 800 # and your insurance." Called 800 line and talked to Giselle, our case manager who said this would be "escalated" and we would hear back in 48 hours. Of course, we did not hear back. Finally, after 2 voicemails and contacting Mazda USA via chat, they call back and say call insurance, it will not be covered under warranty. When I ask for what the escalation was, the rep said "well the dealer said there was a bubble in the tire." Complete runaround. I go to the dealer to return the loaner car and they provide me a watered down and inaccurate report saying the bubble was existing. Insurance has provided an estimate to repair the car for just under $5000. I am not comfortable having the dealer repair the car or any family member drive that car once repaired. Airbag malfunction warning lights everywhere post deployment. No warnings before and ridiculous claim that a bubble in a tire could cause an airbag to deploy. Considering the repair but also legal action as zero empathy by the dealer and no accountability of fixing what seems to be a similar issue in New Hampshire with the same model car 2 years ago.

I have a brand new Mazda CX-30 with less than 10k miles. I was not made aware of the seat material being highly flamible. Luckily I nor my kids were in the car when the seat caught fire due to a magnifying effect. Magnifying Effect (Sunlight): If a clear glass or plastic object (like a water bottle, eyeglasses, or even a certain type of air freshener) was left on the seat in direct sunlight, it could have acted as a lens, focusing the sun's rays onto a small area of the seat material. Over time, this concentrated heat could become intense enough to ignite the fabric, especially if it's dry and flammable. This is more likely to happen on a hot, sunny day. I brought this up with the dealership and their reply was to contact Mazda! YOU are Mazda!

Apple CarPlay disconnects mid-drive, forcing the driver to handle their phone, causing distraction and navigation loss.

None of the features dependent on the Forward Sensing Camera (FSC) of my 2024 Mazda CX-30 are working. I have videos and corroborating statements to confirm that the headlights will not automatically switch from high to low beams, the lane assistance is not working properly, and the "Smart brake support with pedestrian detection" is not working. These defects have been present since I first received the vehicle. The dealer has refused to repair the issues by applying the remedies available under recall number 6824H because my VIN is not included in the recall. I emailed Mazda asking them to contact me and to call the dealer and authorize them to replace the Forward Sensing Camera. I am still awaiting reply from Mazda.

The air bag warning system shows "passenger air-bags not engaged" If involved in any accident that requires passenger air-bags to inflate, they will not. Causing serious to deadly consequences. January 28 2025 the Mazda service department had our vehicle to recalibrating the system. Checking the problem after the service still show the same problem. Another Mazda CX-30 was brought over, and the same problem existed. Also a Mazda CX-5 was tested and no problem was found. This was the second time this problem has been returned to the Mazda Dealership. This problem has existed since purchasing this vehicle.

When driving the vehicle incorrectly thinks there is an object in front of me and engages the emergency braking function. This has happened 3 times since getting the vehicle. The vehicle also occasionally incorrectly indicates there is a vehicle next to me when I turn on my turn signal. This has happened on a clear, sunny day. The incorrect emergency breaking could put me at a collision risk if another car is behind me and/or if engaged when driving at a high speed. This could endanger my life. I took my vehicle in to the dealership to explain the issue and they “could not replicate the issue” thus it was not fixed. There were no other warning signs indicating something is wrong with the vehicle.

The contact owns a 2024 Mazda CX-30. The contact stated while attempting to accelerate from a stop light, the braking system erroneously activated causing the vehicle to abruptly stop. The failure also occurred while driving forward into a parking space. The vehicle was taken to the local dealer who was unable to duplicate or determine the cause of the failure. The vehicle was not repaired. The manufacturer was not yet contacted. The contact was informed that the VIN was not included in the NHTSA Campaign Number: 24V649000 (LANE DEPARTURE, EXTERIOR LIGHTING, FORWARD COLLISION AVOIDANCE). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 2,500.

My car is model CX-30 2024 and I bought it a week ago. The car was turned off with the doors open because I was cleaning it. When I wanted to start the car it gave me an error: “Keyless Entry System Malfunction, have the Vehicle Inspected”, also the start indicator light (amber) flashes. After this error message, I couldn't start the car. I called Mazda where I bought it and they told me to do several maneuvers with the key fob, I also tried with the other key fob and after doing thousands of maneuvers the car didn't turn on. They told me to call Mazda's Emergency Roadside Assistance to have them send the tow truck and leave the car in the Mazda workshop. More than 4 hours passed and the tow truck never arrived, I called Mazda roadside assistance again and they told me that there were no tow trucks available and that it would take another 4 or 5 hours to arrive (that is, around 4 in the morning). It was already midnight, it was cold and I had to leave my son alone at home because I couldn't leave the car in the street. I had to call another tow truck company that could assist me faster (they arrived in 30 minutes). I am completely frustrated and disappointed with the Mazda service because in the workshop they said that the key fob was in hibernation and that's why it wouldn't turn on. It's incredible that this happens with a completely new car (1 week old) and that the dealer says that the car doesn't have any problems. This represents a high risk and danger to anyone if the car suddenly doesn't start and there's no way for it to start. In addition, I had tow truck and Uber expenses to be able to transport myself. I urgently need to review this problem with Mazda, as there are no recalls and they do not respond to this problem.
