GWM Tank 500 Common Problems & What to Watch
The Tank 500 puts LandCruiser-style bulk on a hybrid drivetrain at a sharp price. What deserves watching: brakes and tyres on a 2.6-tonne wagon, hybrid cooling circuits that must be serviced on schedule, transmission calibration that updates have refined, and the reality that any 4WD this heavy is consumable-hungry when it tows.
How booking works: booking online to find out what’s wrong is our $374 incl. GST pre-paid diagnostic — a dedicated two-hour diagnostic booking plus a written report, not a free quote, and it applies even if we find the likely fault sooner.

About the GWM Tank 500
The Tank 500 is the most ambitious thing GWM sells here — a genuinely big, genuinely equipped 4WD wagon. Weight is the story of its maintenance: everything that stops, steers or cushions 2.6 tonnes works hard.
The hybrid system takes the edge off fuel bills but adds its own service points: dedicated cooling, 12-volt care and brake systems that blend regen with friction. All routine — when actually done.
The GWM Tank 500 watch-list
Mass finds the consumables
Brakes, tyres and suspension bushes wear on a schedule set by physics. Pad and disc measurement, tyre rotation and bush inspection at every service keep the big wagon feeling tight instead of tired.
Hybrid cooling on schedule
The battery and power electronics have their own coolant loop with real service intervals. It is cheap maintenance that protects the most expensive components in the car.
Transmission calibration
Owner reports of hunting or occasional harsh shifts have improved with successive calibration updates. Software current plus fluid on its interval is the recipe; heavy towing shortens that interval in practice.
Towing multiplies everything
Rated to tow it is — but towing near the limit cooks transmission fluid, brake fluid and tyres faster than the printed schedule assumes. Tell us how the car is used and we service to the duty, not just the book.
12-volt and sitting time
A feature-heavy hybrid keeps modules awake. If the Tank sits between weekend duties, 12-volt load-testing at service prevents the classic dead-Monday surprise.
Servicing your GWM Tank 500 & keeping the warranty
You don’t need the dealer to protect a new-car warranty. Under Australian Consumer Law, servicing by a qualified workshop, done to the manufacturer’s schedule with appropriate-quality parts, protects your rights — the manufacturer generally can’t refuse GWM warranty cover just because an independent did the servicing, though damage caused by incorrect servicing or the wrong parts wouldn’t be covered. We use the correct parts, stamp the logbook and keep the records that prove every service was done right. With us, logbook servicing starts at $299 incl. GST, and the exact price is fixed in writing before any work starts.

GWM Tank 500 Common Problems — FAQ
Fuel-wise the hybrid helps genuinely. Consumables are honest big-4WD money — tyres and brakes for 2.6 tonnes — and pretending otherwise helps nobody.
Yes — including the hybrid cooling circuit and the checks specific to it, with the logbook stamped. Servicing starts at $299 incl. GST, fixed in writing first.
Check software first: calibration updates have refined the transmission repeatedly. If behaviour persists on current software, that is a diagnostic, and ours comes with a written report.
No — qualified workshop, manufacturer’s schedule, appropriate-quality parts: your Australian Consumer Law rights hold (damage caused by incorrect servicing or wrong parts is the exception, and correct servicing is the whole point), and we keep the records that prove compliance.
