Mazda CX-5 KE (2012-2017): known problems and buying guide

Before you buy

1. On a 2.2 diesel, check the DPF history and the oil level. A DPF regeneration that never finishes is a bad sign, and a rising oil level with a fuel smell is a bad sign too. Ask for oil change records.
2. On a 2.2 diesel built up to 2013, listen for grinding or whining at about 2,500 rpm, and watch for lost power. Either is a bad sign. Ask for proof of camshaft or turbo work.
3. On the 6-speed automatic, drive from N to R and from 2nd to 3rd at 3,000-4,000 rpm. Jolts are a bad sign. Ask whether the firmware update and the adaptation were done; the adaptation needs a diagnostic kit.
4. On an AWD car, look for oil at the rear angle gear and its seals. Ask for angle gear oil records. A leak is a bad sign.
5. On a 2.2 diesel, ask whether the injector seals were replaced. Mazda advises new seals at its 75,000-mile service, about 120,000 km. Ask about oil pressure warnings too.
6. On a 2.0 or 2.5 petrol, check the oil level after a drive and ask for oil records. Oil use above about 300 ml per 1,000 km needs a workshop check.
7. On a 2.0 or 2.5 petrol, a rough idle, a misfire or a hard cold start can mean carbon or clogged injectors. A scanner can read the misfire codes.
8. With the front wheels off the ground, rock each wheel and check the ball joints and the steering for play. Play means a repair is due. Bounce each corner of the car too.
9. Check every open recall campaign for the VIN with a Mazda dealer. The tailgate strut, injector, brake vacuum pump and daytime running light campaigns are in the Recalls table.
