Is there a fix? Manufacturer service bulletins

MT-002/19 09/30/19 and 12/19/19 DESCRIPTION If an engine assembly is replaced after a catastrophic internal mechanical failure, clean the intake manifold internally before installing a replacement engine assembly. If the intake manifold is not cleaned properly, the replacement engine may fail prematurely. Metallic debris from the old engine (with catastrophic internal mechanical failure) may rest inside the intake manifold. When the new engine assembly is installed, debris in the intake manifold will be ingested into the new engine and cause internal damage. Clean the intake manifold

What owners are reporting 4 most recent
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.
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.
"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.
Common questions
How serious is the engine problem on the 2022 Mazda CX-30?
It's a documented issue but not catastrophic. 6 complaints have been filed. Repairs average $3,100 and most owners catch it before it causes a breakdown.
At what mileage does the engine typically fail?
Mileage data is limited for this issue. Owners report failures across a wide range, suggesting cause is more about driving conditions and maintenance than mileage alone.
What does it cost to fix?
Independent shops typically charge around $3,100 for engine repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to engine?
No active recalls currently cover engine issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
