Common Mazda Problems
Mazda is known for its "Jinba Ittai" (horse and rider as one) philosophy, producing cars that are more engaging to drive than their direct rivals. While their petrol engines (SkyActiv-G and SkyActiv-X) are famously reliable and avoid the complexity of turbocharging in many models, their diesel engines and rust protection on older models have been significant pain points for UK owners.
Common Mazda trouble spots
- •2.2 Diesel Oil Dilution: Frequent DPF regenerations can dump diesel into the oil, leading to engine wear or even runaway.
- •MX-5 Rear Arch/Sill Rust: A classic Mazda issue that persists even into the NC generation if not undersealed.
- •SkyActiv-D Camshaft Wear: Early 2.2 diesels (2012-2014) had soft camshafts that would wear prematurely, throwing metal filings into the turbo.
- •Folding Mirror Motor Failure: A very common, annoying fault across almost the entire 2014-2020 Mazda range.
What to check on used Mazdas
- ✓Be extremely cautious with the 2.2 SkyActiv-D diesel engine. It is prone to oil dilution and carbon buildup. Only buy if it has a perfect service history and has been used for long journeys.
- ✓Mazda paint is notoriously thin and prone to stone chips, especially the "Soul Red" tri-coat. Inspect the bonnet and front bumper carefully.
- ✓Check for rust on the subframes and sills, especially on the MX-5 and older Mazda 6 models. UK road salt is not kind to Mazdas.
- ✓The "MZD Connect" infotainment system on 2014-2018 models can suffer from "ghost touching" or reboot cycles. Test it thoroughly during the drive.
Select a Mazda Model
Mazda MX-30
Mazda's first EV focuses on driving dynamics and sustainable materials rather than outright range. Its 35.5kWh battery makes it a niche choice, primarily for urban commuting.
Mazda 3 (BP)
One of the most beautiful hatchbacks on sale, with a near-premium interior. The SkyActiv-X engine offers a unique blend of petrol and diesel tech.
Mazda CX-30 (DM)
The CX-30 fills the gap between the CX-3 and CX-5 with a sleek, coupe-like design and one of the best interiors in its class. It introduced the innovative SkyActiv-X engine.
Mazda 6 (GL)
The second facelift is the nicest Mazda 6 to live with, with better refinement and a richer interior. Late petrol cars are desirable, but the final-run diesels still need close scrutiny.
Mazda CX-5 (KF)
A significant refinement of the original CX-5. Quieter, more comfortable, and more tech-heavy.
Mazda MX-5 (ND)
A return to the lightweight roots of the original. The ND is far better protected against rust than older MX-5s, but early manual cars still need careful transmission checks.
Mazda CX-3 (DK)
A stylish crossover based on the Mazda 2 platform. It offers a premium feel and sharp handling but is quite tight for space in the back.
Mazda 6 (GJ facelift)
The 2015 refresh added a smarter cabin and MZD Connect, but it still shares the same diesel caveats. Petrol cars are the genuinely appealing used buy here.
Mazda 2 (DJ)
The "Kodo" design era Mazda 2 brought a much more premium interior and efficient SkyActiv engines. While reliable, it suffers from some common Mazda-wide electronic niggles.
Mazda 3 (BM/BN)
A sharp-looking and sharp-driving alternative to the Ford Focus. The 2.0 petrol is the one to have.
Mazda CX-5 (KE)
The SUV that proved family cars don't have to be boring to drive. It was a massive seller in the UK.
Mazda 6 (GJ)
The launch-era third-generation 6 is stylish and genuinely good to drive, but early 2.2 diesels are the riskiest cars in the whole Mazda 6 family.
Mazda 5 (CW)
The second-generation Mazda 5 retained the excellent sliding doors but added "Nagare" flow-inspired styling. It remains one of the best-handling MPVs, though it can be costly to maintain if suspension issues are ignored.
Mazda 2 (DE)
The second-generation Mazda 2 moved away from the "mini-MPV" look of the original to become a lightweight, sharp-handling supermini. Sharing its DNA with the Ford Fiesta, it is widely considered one of the most reliable small cars of its era.
Mazda 6 (GH)
The second-generation Mazda 6 is roomy, good to drive and still common in the UK, but rust and diesel DPF trouble define the cars that have aged badly.
Mazda MX-5 (NC)
The "Mk3" MX-5. Larger and more comfortable than earlier models, but still a pure sports car. Prone to rust in the UK.
Mazda RX-8
A brilliant four-seat coupe with a unique rotary engine, but one that rewards informed ownership more than casual used-car buying. Compression, ignition health and rust matter far more than mileage alone.
Mazda MX-5 (NB)
The Mk2 adds refinement and a slightly more mature feel without losing the MX-5 formula. In the UK, structural corrosion is the make-or-break issue.
Mazda MX-5 (NA, late UK cars)
The late Mk1 still delivers the pure, light MX-5 experience, but by now UK survivors live or die on shell condition rather than mechanical complexity.
