Used Mazda 6 (GJ) review
2012 - 2016
Dislikes
- Avoid the Diesels, long list of issues.
- Holds value so good luck finding a bargain.
- Good examples are purchased quickly.
- Early models lacking in tech and equipment compared to updated examples.
Stuff you should know
- The focus of this cheat sheet is on the third generation (2012-2016) Mazda6, specifically the GJ model.
- The current generation Mazda6, known as the GL, shares a striking resemblance with the GJ, with minor aesthetic and equipment differences. Mazda considers the GL different enough to have its own designation.
- The close linkage between the GJ and GL suggests that insights from the early GJ model can provide a valuable indication of how the GL will age in the coming years.
- GJ models are offered as sedans or wagons, featuring either a petrol or diesel engine that powers the front wheels through a 6-speed automatic transmission.
- In Australia, the GJ lineup includes four trim options, and a significant update was introduced in 2015. Detailed technical specifications and a breakdown of trim specs are available below.
What goes wrong
EXTERIOR:
- Owners have frequently complained about the paint scratching easily, particularly noticeable in 2017 and 2018 models with the attractive Crystal Red Metallic colour (GL series).
- Some owners reported the front lower lip being prone to scraping on driveways, although individuals experienced with lowered performance cars haven’t encountered issues with it.
- Concerns have been raised about the low quality of the rearview camera, described by some as being comparable to a potato, indicating a need for improvement.
INSIDE:
- Numerous owners have expressed dissatisfaction with the i-stop technology, which automatically turns off the car when stopped at traffic lights to save fuel. Complaints include battery management warnings and debates on its impact on battery life.
- Trim fabric on door cards in earlier models may come loose, but it’s considered a simple and inexpensive fix.
- Some sporadic reports mention issues with Bose amplifiers, resulting in white noise or muffled music. Independent hi-fi or electronics repairers are suggested for cost-effective solutions.
- Occasional complaints about frozen screens, primarily on MZD systems, can generally be resolved by restarting the car or performing a software update.
- Few owners have mentioned inadequate air conditioning performance, but it appears to be an isolated issue.
MECHANICALLY:
Petrol Models:
- Generally, petrol examples are highly reliable.
- Direct injection motors may require walnut blasting or chemical cleaning of inlet tracks over time, a common maintenance procedure.
- Sporadic reports of high-pressure fuel pump issues.
- Occasional problems related to oil pressure, potentially linked to the strainer, pump, or relief valve.
- Rare occurrences of timing chain issues.
- Common engine mount problems, causing a loss of dampening fluid and a vibrating sensation throughout the car.
Diesel Models:
- Strongly advised to be avoided due to numerous reported issues, including turbo failures, waste gate problems, camshaft failures, and injector seal issues.
- Non-genuine parts for exhaust pressure sensors and upgrade kits are available, often at a more affordable price.
- Increasing concerns about injector seal and oil pressure problems, including blocked strainers due to carbon from injector seals.
- Issues with coked up inlets, shutter valves, and EGR complications.
- Common DPF (Diesel Particulate Filter) problems and oil dilution issues in examples not meticulously maintained.
Transmissions:
- Earlier models with transmissions made by Jatco had reported issues, but this generation’s transmissions, made by Mazda, are generally considered fault-free.
- An occasional Selector position fault can occur inside the car, but it’s a minor issue with an easy fix.
