At around 26,528 miles my 2022 CX-30 2.5s (not the turbo) developed a "Low Oil Pressure" warning while driving between 55-65mph on 07/06/2025. The car has had regular oil and filter changes about every 5K miles. The last oil and filter change was at 25,259 mileage on 05/25/2025. There aren't any visible oil leaks. I have read that this is a common problem for other Mazda CX-30 years 2021- 2022.
It has an oil consumption issue. Every 3,000-3,500 miles is will give the oil low light. It will be 1 quart low. The car takes 6 quarts of 5w30 synthetic oil and requires oil changes every 7,500-8,000 miles. I have had to put a quart in every time. I have taken it into the dealership and a third party oil service as well. The dealership has no idea why it keeps running through the oil. They state that it's a known issue but no recall.
The vehicle show "low engine oil" warning every 3k-4k miles although I change engine oil and filter regularly.
There have been 3 different ongoing issues. The car was ordered and delivered brand new in April 2022. At 4,000 miles and again at 12,000 mile is would display low oil and require 1 quart of oil. The dealership acknowledged that it has an oil consumption issue, unresolved. I have to bring it in every time it is low prior to its required oil change time/miles. At 19,742 miles the cars battery died. They replaced it an have no reason why it died. Every time I'm driving in the mountain pass the transmission will not advance above 3rd gear. The engine will whine and I have to put it into manual and move it to 4th and or 5th gear. When I coming down the other side of the mountain, I have the same issue with it only advancing to 3rd and not proceeding to 4th or 5th. Then when I reach the bottom and on flat road the message- safety system and deactivated. This last for apx 10 minutes. The dealership has no idea why it does it.
Passenger seat belt was stuck retracted and had to be replaced. Coolant temperature control valve failed and car ran cold. They have many cars with this issue but no recall was issued
"low oil" indicator came on after less than 5000 miles after oil change. Found oil to be 1 quart low. Scheduled oil changes are 10,000 miles apart, which suggests engine has defect which allows oil to be consumed within the engine. No signs of oil leakage.
On December 26, 2022, after running errands for an hour or so and parking outside in parking lots, I restarted the car and pulled out of a parking lot. 3 dashboard warning lights flashed, one after the other: Engine malfunction, have vehicle inspected; Dynamic stability control malfunction, have the vehicle inspected; Safety and driver support systems partially disabled, drive safely. Vehicle was stuck in high gear and would not shift to lower gear as I pulled into the driveway (fortunately I was close to home), forcing me to have to floor the gas pedal to go up the very slight driveway incline. Dealership thought they fixed the problem, exact same thing happened on 12/28/22 (same dashboard warnings, stuck in high gear) when we were on the highway. Car was barely able to make it up the exit ramp in heavy traffic, could easily have been rear-ended. We were able to get the vehicle home by driving in Manual. It would still not downshift, even in manual, but we managed to get home (about 20 miles) in high gear with slow acceleration. Once again dealership thought they fixed the problem. Exact same thing happened (same dashboard warnings, stuck in high gear) for the third time on 1/31/23. Fortunately I was close to home and was able to pull up the driveway by flooring the gas pedal once again. Car is currently at the dealership service center again. Vehicle has 8,156 miles.
I purchased a new 2022 Mazda CX-30 in early 2022. While driving home from out of state recently, a low oil warning light popped up on the dash. I immediately pulled over and checked the level to find only 2-3mm of coverage on the dipstick, well below the safe range. I topped the engine off with a full quart of oil. The vehicle only had 68xx miles on it when this happened.
Low oil light came on twice in first 6,000K. Had to use a quart of oil (total) to refill. Oil dipstick showed low oil both times. Engine is consuming oil with no obvious leaks noticeable on exterior components.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
