There are 2 owner-reported driver assist & adas complaints for the 2022 Mazda CX-30in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
I've used cruise control for decades and use it even on city streets, so I can concentrate on the road rather than my speed. The concept of adaptive cruise control is great, but the execution is very flawed on my Mazda CX30. The system fails to recognize lane separation and turn lanes where lines do not exist. The result is the Mazda CX30 adaptive cruise frequently brakes to slow the car for vehicles not in the lane it is in. At some point this is going to result in a rear end accident, because of other vehicles not allowing proper distance and my Mazda CX30 slowing for no valid reason. I shared this issue multiple times with dealership service, with Mazda via their website and with Mazda via emailed surveys. Dealership service says everything is working correctly. Mazda has not responded. If I could turn this functionality off, and have it stay off, I would do so and not report it here, but it turns back on every time the car is started. I was puzzled by this being an issue for me, on my Mazda CX30, but not for friends with other vehicles. What I learned talking to friends is that they rarely use cruise on city streets, which is the primary location for the issue. I discovered a Cheverolet Traverse, I rented, only beeped at me when it detected issues at locations where the Mazda CX30 slowed.
While exiting the freeway there were no cars in front of my vehicle. The vehicles “smart braking system” triggered seemingly at random and brought the vehicle to an immediate stop. This is incredibly dangerous.
