The vehicle is experiencing premature transmission failure, since about 9,000 miles. Mazda has been dropping the ball at replacing it under warranty and we found out there are 3 other CX-30s that I know of with similar issues. I believe Mazda has a faulty transmission in these cars based off my findings and other complaints.

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.

What is happening with my car are the exact symptoms of the known Mazda Recall 6824H - where the Smart Brake Support suddenly engages for no reason and when it does not need to - which has almost caused me to be rear-ended a few times. This has happened at least 7-8 times since I have owned the vehicle. Apparently, my VIN does not fall under the cars that Mazda reports for the Recall, but nonetheless, my car is still malfunctioning as the Recall describes, which is a safety issue for me. The Recall also states: "Due to an improper program setting, affected FSC (cameras) were not updated from production mode to normal mode. As a result, all three systems described (HBC, SBS, LAS) will not work as intended." My cameras are definitely not working as they should. I have had it in for service, and the technicians have not done anything at all. The Recall should definitely be expanded to owners experiencing these issues. As I have stated above, this incident has occurred at least 7-8 times, so I'll just enter in the most recent time that it happened in the Additional Details below since I cannot enter all of them. Thank you.

Reporting Product Defect in Mazda Vehicles I am writing to bring to your attention a recurring design flaw affecting current Mazda vehicles, including models such as CX30, MX30, and potentially the Mazda3 series. Following heavy rain or high humidity conditions, there is a consistent issue with the tire pressure sensor alarming and the smart key being unable to unlock the car doors. I have checked my key fob battery, RF function, car battery - none of these are the root cause. Despite consulting local dealerships and various Mazda forums, no one seems to have a definitive solution to this problem. Therefore, I am reaching out to report the existence of this product defect. This issue appears to be more prevalent during summer in Arizona - after the thunderstorms, this issue came up every time. Even with the heat here, it takes from several hours to 2 days for the affected part to dry out and function again.

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 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 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.
