Common Infiniti QX80 problems & repair costs
Fuel Consumption & Running Costs
5.6L V8 averages 10–12 L/100km; annual fuel budget R80k–R100k+ at current petrol prices. Servicing is Infiniti-specialist only, parts expensive.
Limited Local Service Network
Infiniti dealerships concentrated in Gauteng/Western Cape; out-of-warranty repairs require specialist imports or improvisation. Parts lead times 4–8 weeks.
Depreciation & Resale
Niche market in SA; slower resale than Toyota/BMW. 2024 model at 40–60k km already ~42% below new list by year 5.
Buyer's inspection checklist
🔧Engine & Drivetrain
Cold start & idle smoothness — V8s develop carbon and timing issues; rough idle or stuttering signals neglect.
Transmission response (1st–2nd shift) — 7-speed automatics can develop delay or hunting between gears if fluid not changed on schedule.
🚗Body & Exterior
Panel gaps & respray signs — Large SUV panels are costly to replace; accident history is critical for resale.
Roof rack & trim corrosion — Aluminum trim and anodized parts corrode in coastal/high-humidity SA climates after 3+ years.
💡Interior & Electronics
Infotainment system & connectivity — 2024 models have complex multi-media; software glitches require dealership resets (time/cost intensive).
Seat heater & cooling functions — Leather seat climate control is common failure; replacement is R8k–R12k per seat.
📋Service History
Oil & transmission fluid service records — V8 owners who skip oil changes face sludge; transmission fluid neglect causes slipping.
Infiniti dealership vs independent repairs — Warranty voids if serviced at non-approved shops; specialist repairs may not match warranty terms.
