Engine is consuming/burning oil. I have needed to add 1 qt of oil every 3-4k miles, since purchased new. Car now has 25,000 miles and I have added oil 6 times.

The car has been reporting low engine oil numerous times between oil changes.
I have just about 8800 miles on my Mazda CX-30 Turbo after a year and 5 months. Suddenly had my low oil engine light come on. I pulled over and the oil is barely on the tip of the oil stick. My last oil change, which was also my first, was completed at 4937 miles from the Mazda dealership.

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.
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…
