MG Repair Costs

MG ownership & common problems

What Our Data Reveals About MG

MG is the cheapest brand to repair in Australia — 0.81x Toyota in our index — and it is not even close. The MG3 (their smallest hatchback) costs less to maintain than any other new car sold in Australia. The reason is simple: MG deliberately engineers for repairability. Parts are sourced from the same suppliers as Chinese-market vehicles (massive volume = low cost), and the mechanicals are deliberately conventional — no complex turbo systems, no air suspension, no 48V mild-hybrid architecture. The trade-off: our data also shows MG has the longest average wait time for body panels and electrical components (7-21 days from China), and the dealer network is still thin outside capital cities. If you live within reach of an MG dealer, ownership costs are exceptionally low. If you do not, factor in the possibility of longer repair timelines.

MG's electric range changes the servicing math entirely, and it matters because MG sells more EVs to Australian buyers than almost anyone — the MG4 and ZS EV are regularly the cheapest new EVs in the country. EV servicing strips out the two biggest recurring costs: no oil changes and no transmission fluid, with MG's capped-price EV services typically running $180-$280 per visit versus $320-$450 for the equivalent petrol MG3 or ZS. What you still pay for: cabin air filter, tyre rotation (EVs wear tyres 15-20% faster due to battery weight and instant torque), brake fluid every two years, and an annual battery health check. The high-voltage battery is covered for 8 years/160,000 km (industry standard), separate from the 7-year vehicle warranty. One warning from our repair data: EV-specific parts — charge ports, onboard chargers, DC-DC converters — still ship from China on the same 7-21 day timeline as body panels, and only MG EV-accredited workshops can touch the high-voltage system, so a charge-port fault that a mechanic could fix on a petrol car becomes a dealer-only job on an MG4.
