    Excessive oil consumption. I bought this vehicle new from a Mazda dealership, with factory warranty. The check engine oil light came on at approximately 6800 miles, 3750 miles after the first oil change. An additional quart of oil was added. I brought it back to Mazda to confirm no oil leaks, which they confirmed. They were made aware of the Mazda service bulletin for excessive oil consumption, which they acknowledged, but indicated they will monitor as there is no solution from the factory.

    The automatic braking engaged without warning and without cause. There was nothing directly in front of the car that was a possible collision threat. I suffered a neck injury as a result of the force in which the car stopped. Fortunately the driver behind me was able to stop. The car was taken to the original Mazda dealer and I was told this is a problem with my car but that they had no permanent fix, nor the ability to permanently shut off this system available until "corporate got back to them." They did not provide any paperwork and stated "we will call you when we have something." I now have a car I am scared to drive.

    Yesterday I heard a very light ting sound. I did not think much of it. When I stopped I checked for any windshield damage, I could not locate any. After having the car parked for several hours, to my utter shock I had about a 1' long crack in my windshield. After looking for some time, I located the microscopic chip that caused the issue. I believe the windshield is defective! It is either too thin, too brittle, or both. Which could be a safety hazard.

    low oil indicator keeps coming on at 3k miles and 8k miles. some times the oil is slightly low. The manual says to sop driving immediately, but that is not always possible.

    My car is burning a quart of oil every 1500 miles. I have taken it to the dealer three times. They say that they know about the problem but don't have a fix. I am afraid that the engine could seize up during driving, causing a accident.

    Driving home from work today I got a "low engine oil level" alert/warning. First time this has happened. I have approx. 15,500 miles on my vehicle and it was serviced on 3/22/22 (11,828 miles). That service included a full oil and filter change. I see it has been noted that there is an oil leak with this particular vehicle but Mazda has not been able to figure out what is causing it. Just wanted it to be reported

    The windshield in my 2021 CX30 had a distorted view on the passenger side of vehicle. Took it in to dealership who confirmed that there was obvious distortion in the windshield. Windshield was replaced and the new windshield has the same issue. Mazda is now saying that it is "normal" to have some distortion on this particular model and they will not replace the windshield again.
