Credov's researched list of the 3 faults the Nissan Navara ST-X 550 is known for (2010–2015), 3 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.
What to look for: Listen at idle and under load for a deep knock, and check the oil light stays out once running.
Why it matters: Once a main bearing spins, the block usually needs line-boring and oversize bearings or a replacement engine, which is one of the biggest repair bills this ute can have.
Typical repair: NZ$8,000–NZ$15,000 in New Zealand · A$8,240–A$15,450 in Australia
What to look for: Look behind the bumper and bash plate for oily wetness, and feel for flat power or black smoke when accelerating.
Why it matters: A leaking intercooler loses boost and pushes oil out, so the ute is down on power, smokes and uses more fuel, and the part is expensive to replace.
Typical repair: NZ$1,200–NZ$3,000 in New Zealand · A$1,240–A$3,090 in Australia
What to look for: Listen for a metallic rattle from the engine in the first seconds after a cold start, and check for a warning light.
Why it matters: A stretched chain upsets engine timing and, if ignored, can jump or break and wreck the engine; the repair is labour-heavy on this V6.
Typical repair: NZ$4,000–NZ$8,000 in New Zealand · A$4,120–A$8,240 in Australia
