2021 Mazda CX-30

Engine trouble leads the 94 complaints. Oil drops with no visible leak, and the low oil light can appear as early as 4,600 miles. Some owners add a quart every 1,500 miles, and dealers often call it normal. Others report flat batteries that need jump starts and wavy windshield glass that causes eye strain.

Frequently Asked Questions

Which Mazda CX-30 years should I avoid?
Avoid the 2021. Site analysis puts it well below the model's own average. It has 94 owner complaints, 36 of them about the engine, plus battery drain and windshield distortion. The 2024 is the better choice among years with a track record.
Does the 2021 Mazda CX-30 have engine problems?
Yes. Owners describe oil disappearing between changes with no visible leak, and the low oil light sometimes appears around 4,600 miles. Several reports involve the 2.5-liter turbo. Dealers often confirm there is no leak and call it normal or cite a service bulletin without a fix.
Is the 2020 Mazda CX-30 a bad year?
The site does not flag it as one to avoid. It shares the lowest rating tier with the 2021 but has 31 complaints, or 8.1 per 10,000 sold, and 3 recalls. Its most reported areas are unknown or other, electrical, and structure. Check recall status by VIN.
Is the 2024 Mazda CX-30 safe to buy?
It is the site's pick, but it is not trouble free. It has 2 recalls and 1 fire report. Owners also describe airbag warnings, false braking, and sudden electronics failures. Run the VIN for open recalls and test the driver aids before you buy.
Is the 2026 Mazda CX-30 the best year to buy used?
No. The 2026 shows 0 complaints and 0 recalls, but that mostly means it has had little time on the road. Problems build up over years. Until it has a record, the 2024 is the safer pick.
