Oil consumption & Engine issues are among the top complaints received by the NHTSA from vehicle owners
The 2022 Mazda CX-30 is the third model year for this subcompact crossover SUV. It has all the standard features of the 2021 model and is largely unchanged.
According to Mazda, sales from 2020 to 2021 almost doubled, moving up from 38,064 units to 60,185. This trend looks likely to continue, since they had already sold 27,767 CX-30s between January and July, 2022.
So, it’s relatively popular, but it’s certainly not without its problems.
Lemberg Law currently has a class action investigation into oil consumption issues plaguing the 2021 Mazda CX-30. It’s not difficult to see that this same problem is carried through to the 2022 model.

It should come as no surprise to learn that the most common problem 2022 CX-30 owners are complaining about to the Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) is the oil consumption issue.
Evidence of a crash indicates that there are other system failures as well.
| Complaint Category | Number of Complaints |
|---|---|
| Engine | |
| Unknown Or Other | |
| Steering | |
| Electrical System | |
| Forward Collision Avoidance: Adaptive Cruise Control | |
| Seat Belts | |
| Visibility/wiper | |
| Air Bags | |
| Forward Collision Avoidance: Warnings | |
| Power Train |
So far, the only engine problems reported to the NHTSA by 2022 CX-30 owners relate to oil consumption without leaks. This is exactly the same problem reported by 2021 CX-30 owners. For this reason, it’s worthwhile having a closer look at the 2021 experience.

Mazda issued four technical service bulletins (TSBs) to the NHTSA between April 30 and November 24, 2021.
The first reports vehicles that display the “check engine” light. The reason, they said, was contamination in the engine oil. This “may cause the engine oil solenoid valve to become stuck, resulting in improper operation of the oil pump and improper oil pressure.”
The solution was to:
Later TSBs, including the most recent one filed with the NHTSA on November 24, 2021, offer very different advice.
These confirm that some vehicles get the “low engine oil level” warning and a “check engine” light when engine oil levels are low. But “there doesn’t appear to be any trace of oil leakage in the engine compartment.”
This problem usually occurs when the mileage reaches approximately 3,100 – 4,700 miles.
In the most recent, November 2021, TSB dealers are instructed to tell customers:
“A small amount of the engine oil may be leaking into the combustion chamber, causing the oil consumption. Mazda has confirmed this oil leakage into the combustion chamber will not cause any immediate engine damage and the vehicle may be safely driven. The warning message and CHECK ENGINE light will go off by topping off the engine oil level.
“This is only a temporary repair and as soon as Mazda identifies the root cause, a complete repair procedure will be announced. Mazda will top off or replace the engine oil at no charge until the complete repair is provided.”
You will see from the complaints below that the issues experienced by 2022 CX-30 owners are clearly the same. However, Mazda hasn’t extended the TSBs to cover this model. Also, Mazda hasn’t yet announced a complete repair procedure.
An owner from Massachusetts states: “Low oil light came on twice in (the) first 6,000 K. 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.”
An owner from Tennessee states: “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.”
Although there is only one complaint about system failures, it’s a serious one that resulted in a crash. Although listed under Steering, Service Brakes, and Unknown or Other, it could be categorized as a forward collision avoidance problem.
The owner reports he put the car into reverse, “and it leaped forward and crashed and caused property damage.” Shocked by the incident, he blames a “faulty system” as well as “collision system failure” and “reverse gear failure.”
On two other occasions, the car initiated warnings like the misuse of pedals when the car was rolling downhill. He blames this on “false lane assist warnings.”
When a manufacturer admits they cannot identify the root cause of a problem, this is cause for concern. Apart from anything else, if they can’t fix it, the problem may recur many times.
A lemon, by definition, has persistent defects that substantially impair the safety, use, and value of cars and other items. So, if your car cannot be repaired, there’s a good chance you’ve bought a lemon.
In that situation, it’s a good move to let experts take over and negotiate a settlement of some sort for you.
Lemberg Law specializes in lemon law and helps to solve your lemon problems at no cost to you. Options we negotiate include replacement cars, buybacks, trade-ins, and cash settlements. It depends on the car and circumstances. But the good news for you is that the law insists Mazda must pay legal fees for lemon cases.
