Power Train

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.

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.

What component or system failed or malfunctioned, and is it available for inspection upon request? The automatic braking turned on while I was accelerating. My car is available for inspection. How was your safety or the safety of others put at risk? I could have been rear ended because my car automatically braked at an unpredictable time in rush hour traffic with someone very close behind me. Has the problem been reproduced or confirmed by a dealer or independent service center? It has happened to me maybe 4 times before but the dealer hasn't been able to reproduce it. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? It first happened soon after I bought my car new.

It looks like the clips that hold it in place have become worn or loose by the weight of the gas nozzle or by the fact that the gas door will not close correctly and car wash machine has made it looser and it appears to not shut all the way, and the body colored panel has fallen off as a result and when you pump gas, the assembly moves may be possibly causing it to leak gasoline if the seal or gasket becomes dislodged because of the loose clips that hold assembly to the body panel.

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.

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.

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.
