Credov's researched list of the 5 faults the BMW X3 is known for (2010–2014), 5 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: On slow full-lock circles feel for binding or shudder, and watch for 4x4, ABS and brake lights together.
Why it matters: A failed actuator or clutch pack leaves the car without proper four-wheel drive; typically NZ$500-$5,500 depending on whether it is the actuator or the whole case.
What to look for: On the test drive watch the temperature reading and the dash for a coolant or overheating warning.
Why it matters: The pump fails with no warning and driving on risks a warped head; typically NZ$1,200-$2,200.
What to look for: On a long test drive watch the temperature reading and the dash for a coolant or overheating warning.
Why it matters: No-warning failure risks overheating, power loss or a stall; typically NZ$1,200-$2,200.
What to look for: Listen at the gearbox end of the engine on a cold start for a scraping or rattling noise.
Why it matters: A snapped chain wrecks the engine and needs an engine-out repair; typically NZ$4,000-$9,000.
What to look for: Look for an emergency-call warning on the dash, test a Bluetooth call, and check the headliner for stains.
Why it matters: A failed SOS, GPS and Bluetooth system is both an inconvenience and, if it is ever needed in a crash, a safety gap; repairs commonly run NZ$1,500-$4,500.
