Used MG MG3 review
2016 - 2022
Dislikes
- Low cost equates to many compromises in the production process.
- MG often struggle to supply certain spare parts.
- Depreciation is concerning and most likely won’t stop.
- There are so many other cars you should buy instead.
Stuff you should know
- The 2016-2023 MG3 has made its mark as one of Australia’s most affordable new cars, drawing attention from budget-conscious buyers. On the used market, the MG3 becomes even more appealing with some recent models now asking just over $10,000, however we feel the MG3 needs to be approached with caution.
- The MG3 lineup has included basic variants like the Core and higher trims like Excite and Essence, offering simple, budget-friendly features. The higher trims add some minor upgrades in technology and convenience, but overall, the range remains focused on affordability.
- In terms of power plant, it is powered by a 1.5-litre 4-cylinder petrol engine paired with either a 4-speed automatic or 5-speed manual transmission. This setup prioritises low cost over driving refinement, making it ideal for urban commuting but less impressive for highway driving.
- An update in 2018 refreshed styling that included a revised grille and bumper, along with new headlights. The interior was upgraded to include a 7.0-inch touchscreen with Apple CarPlay on some trims, adding a modern touch for tech-savvy buyers.
- The interior design is simple and utilitarian, with hard plastics throughout. Comfort is sufficient for city driving, though longer journeys may expose the basic seating support. Rear space is decent but isn’t class-leading.
- Base models come with essentials like air conditioning and power windows, with higher trims adding a reverse camera, Apple CarPlay, and rear parking sensors after the facelift. However, advanced safety features like autonomous emergency braking (AEB) and lane-keeping assist are absent.
- MG offers a standout 7-year warranty with the MG3. However, parts shortages have been an issue, leading to delays in warranty repairs. This is a concern for owners needing their vehicle back quickly.
- Affordability can mean compromises in build quality. While some owners have positive experiences, others report electrical and durability issues, suggesting inconsistent quality control.
- The MG3’s low new-car price also contributes to high depreciation. Many MG3s lose over 40% of their value within a few years, which makes them an affordable option on the used market but may deter buyers looking to retain value.
- Potential used MG3 buyers should check for a solid service history, and watch for electrical issues or mechanical wear. Parts availability may still be an issue for maintenance, so prospective buyers should factor in possible delays.
- The MG3’s low price and long warranty make it appealing for budget-focused buyers, but it comes with trade-offs in build quality, retained value, and support turnaround, making it most suited for buyers prioritising cost over premium features or refinement. Just be aware of what you might be getting yourself into, read on to find out what that might include…
What goes wrong
Exterior Issues
- Many MG3 owners report that the paint quality is thin and prone to scratches, even from gentle handling like drying after a wash.
- An even more serious paint issue, especially with 2019 white models, is peeling along the roof’s leading edge, similar to issues seen on early 2010s Toyota models. While many dealerships have resolved this under warranty, some owners have encountered issues when MG declined repairs from their preferred body shops due to higher repair costs.
- Another common complaint is water leakage into the rear lights after rain or washing. Dealerships usually replace these under warranty, though the parts can be back-ordered, resulting in frustrating delays for owners.
- Part availability is a recurring theme in MG3 forums; while the car comes with a 7-year unlimited-kilometre warranty, some warranty claims are delayed due to slow parts supply, leaving owners waiting weeks or even months for repairs.
- The stock halogen headlights also draw criticism for their poor illumination, with many owners installing aftermarket light bars for improved visibility at night.
- Rust is another potential issue, with some owners reporting rust spots on the underside of body panels, bonnet latch hooks, and other areas. However, others— even those in coastal areas— have had no issues, indicating inconsistency in quality.
- Premature wear on brakes and tyres is also reported. Brake pads and rotors can squeak or squeal and tend to wear quickly, with MG’s replacement costs often being high. Aftermarket alternatives are limited, making it harder for owners to find better-performing options. For tyres, upgrading to higher-quality options and getting a professional alignment can significantly improve the car’s handling.
- One surprising note for some buyers is that MG, once a classic British brand, is now owned by China’s SAIC Motor. All MG3s in Australia are manufactured in China, not England.
Interior Issues
- Interior durability is another area of concern, with rust occasionally appearing on some structural elements under the dashboard. Like the exterior rust issue, this seems inconsistent, so prospective buyers should inspect the area beneath the dash for any rust spots.
- Ergonomics also receive mixed reviews. There’s no driver’s footrest, and depending on the driver’s height, the sun visor can obstruct the rearview mirror. Front seats reportedly lack lumbar support, which may impact comfort on longer drives.
- The infotainment system, particularly when using Apple CarPlay, has received a lot of complaints about reliability. Owners report issues like random pauses, audio dropouts, screen freezing, or a default loud volume setting each time the car starts.
- Additionally, Android Auto isn’t supported, so Android users are limited to Bluetooth connectivity.

Mechanical Issues
The MG3’s 1.5L engine is closely related to a General Motors engine used in other models, although Chinese-manufactured examples have shown better reliability than those made in North America. Despite this, a number of mechanical issues have been reported:
- Premature wear on ignition coils and spark plugs
- Excessive oil consumption, especially in higher-mileage examples
- Radiator leaks or splits, which can lead to overheating and potential head gasket issues if left unchecked, although severe cases are uncommon
- Timing chain rattle, though complete failures haven’t been widely reported, is something to monitor
- Oil leaks from the valve cover and timing cover
- Premature failures in the low-pressure fuel pump
- Air conditioning components, including the compressor and hoses, can be problematic
- Brake shudder, often emerging prematurely, with limited aftermarket parts available
- Rear wheel bearings wearing out earlier than expected
The transmission, while generally reliable, is an older design that lacks modern smoothness and refinement.
Perhaps the biggest concern for MG3 owners is the difficulty in obtaining replacement parts, which can turn minor warranty issues into extended waiting periods. While the 7-year warranty is generous, it’s not always fully effective due to parts shortages.

Should you buy it?
It might sound like the MG3 is a bit of a risk, but for many owners, that hasn’t been the case. In our research, we found numerous reports from owners who love their MG3 and have experienced no issues. However, there are also plenty of owners who say they’d never buy an MG again.
For us, though, beyond any reliability concerns, the main reason we’d hesitate to recommend the MG3 is that you could consider some excellent alternatives in the $10,000 to $20,000 range.
Options like the Toyota Yaris and Mazda 2 may be older and a bit smaller but come with stronger reputations for build quality and reliability. You might also consider the Kia Rio or Hyundai Accent—these would be older models but are similar in size, with potentially more equipment and a superior driving experience.
If it were us, we’d be looking at models like the Honda Jazz or Suzuki Ignis instead. Both offer better build quality and reliability and are financially smarter choices. The Jazz is easily the most practical in its class, while the Ignis is fun to drive and well-equipped for the price.
That said, if you’re looking for a basic, affordable vehicle to use as a second car or an everyday commuter, the MG3 isn’t necessarily a bad choice. Just remember: this is a situation where you get what you pay for.
