ExtremePLUSPDFExtensive MBI protection for a wide range of mechanical and electrical components, with an Electric Vehicle Package for eligible vehicles.
SmartCoverPDFA modern vehicle has hundreds of mechanical and electrical components. Autosure MBI helps with the cost of sudden, unforeseen breakdowns of covered parts — not just engine repairs.
Examples include cylinder heads, pistons, oil pumps, timing chains, turbo components, fuel pumps and injectors.
Examples include automatic and manual gearbox components, torque converters, differentials, drive shafts, CV joints and 4WD transfer boxes.
Examples include alternators, starter motors, engine computers, window motors, air-conditioning compressors and condensers.
Examples include power-steering racks and pumps, wheel bearings, suspension arms, brake callipers and ABS modules. Brake pads and other friction materials are excluded.
Additional cover includes specified factory-fitted cameras and driver-assistance systems, keys and remotes, powered seats and tailgates, sunroof components, audio systems, adaptive suspension and shock absorbers. Consumables required for an accepted claim can be covered up to $750 per claim. Conditions and exclusions apply.
Examples only — not every component is covered by every policy. Pre-existing issues, general wear and tear, routine servicing and impact damage are not covered. Repairs require Autosure’s prior authorisation. Follow the servicing requirements in your policy and retain your service records.
The Electric Vehicle Package includes specified factory-fitted drive-unit/inverter, dual charger and traction-battery components. Gradual battery capacity loss is excluded.
Battery repair or replacement contributions: SmartCover — up to $5,000 for vehicles up to 10 years old, or $2,500 over 10 years; ExtremePLUS — up to $10,000 for vehicles up to 10 years old, or $5,000 over 10 years. The scheduled excess is deducted. Only one battery replacement is covered per period of insurance.
These are policy limits, not a promise to pay the full repair bill. All cover is subject to the policy wording and your schedule.
The cost of the unexpected
From an electrical fault to a major transmission repair, the bill can quickly reach thousands. These examples from Autosure show average repair costs including parts and labour.
