I'm reporting significant safety issues. All are related as they indicate that the error rejection for the sensors are not properly calibrated. These false positive errors are dangerous. It affects the automatic emergency braking, forward collision, blind spot, and cross traffic warning systems. 1. What component or system failed or malfunctioned, and is it available for inspection upon request? The sensor responsible for detecting road impediments and cross-traffic/blindspots. I'm not sure how to provide it for inspection. How was your safety or the safety of others put at risk? YES - when safety systems frequently have false positive indicators (auditory and visual). This has caused the car and driver to respond to a threat that is not real. This can also cause ignoring true positive indicators (alarm fatigue) and uncertainty of the systems ability to respond to true negative events. Has the problem been reproduced or confirmed by a dealer or independent service center? No, but they are incompetent. I was told the issues might be: bugs on the sensor, maybe a plastic bag floated by the car, maybe the road was shiny, maybe there was something and I didn't see it. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Not to my knowledge. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, this is a brand new vehicle (2023) and we are the only drivers. These issues have been happening since we started the lease. The cross/blind spot false positive happen daily. The braking/front end collision have only happened ~4 times.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2023 Mazda Cx-30 verdict →
