Mitsubishi Pajero NP common problems: what to check before you buy
Credov's researched list of the 6 faults the Mitsubishi Pajero NP is known for (2003–2006), 6 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
Known problems on the Mitsubishi Pajero NP
Brake booster pump or accumulator failing
Safety risk
2000–2006 · Brakes
What to look for: With the engine running, pump the brake pedal hard ten times, watching for the brake warning lamp and listening for a buzzer.
Why it matters: Losing booster pressure makes the brake pedal very hard and stopping distances much longer. The pump and accumulator are specialist parts.
Typical repair: NZ$600–NZ$3,000 in New Zealand · A$620–A$3,090 in Australia
What to look for: At a cold start with the bonnet up, listen for a rattle or slap from the top front of the engine.
Why it matters: Owner reports cluster between about 100,000 and 160,000 km, and Mitsubishi revised the guide for Gen 4. The guide is a cheap part; chain, tensioner and lever are checked at the same time. Repairs reported in the roughly NZ$600-$3,500 range.
What to look for: Find the timing belt sticker or receipt and check it was done within the last 90,000 km and six years.
Why it matters: A snapped belt on this engine means bent valves and usually a head rebuild or replacement engine; an overdue belt should be priced into the deal.
Typical repair: NZ$1,200–NZ$2,500 in New Zealand · A$1,240–A$2,580 in Australia
What to look for: With the engine idling, look at the crank pulley for a wobble or a step between its rings, and listen for squeal.
Why it matters: If the outer ring lets go it throws the drive belt (no charging, power steering or air-con) and can damage the timing belt area behind it, risking engine damage.
Typical repair: NZ$500–NZ$1,300 in New Zealand · A$520–A$1,340 in Australia
What to look for: Look in the coolant reservoir and radiator for a pink, brown or milky oily film or sludge.
Why it matters: Caught early it is a radiator and flushes; once coolant has got into the automatic, the gearbox usually needs a rebuild or replacement.
Typical repair: NZ$700–NZ$5,000 in New Zealand · A$720–A$5,150 in Australia
