Credov's researched list of the 5 faults the Holden Commodore SV8 is known for (2006–2013), 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: Drive slowly over a speed bump and listen for a clunk from the front, then brake firmly and feel for a shimmy.
Why it matters: A separated front ball joint is a loss-of-control risk, and this is reported as a very common wear point on these heavy cars well before 100,000 km.
What to look for: Watch the ABS and stability control lights go out a few seconds after start-up and stay out through the drive.
Why it matters: Losing ABS and stability control removes a real safety margin in an emergency stop or on a wet road, and a replacement or reprogrammed ABS module is an expensive, non-trivial repair.
What to look for: With the engine cold, look at the radiator end tanks and upper hose neck for cracks, crust or weeping.
Why it matters: A sudden, total coolant loss on the road can overheat the alloy engine enough to warp the heads or blow a head gasket before the driver can stop.
What to look for: Look up at the whole roof lining for a sagging cloth and gently press for a soft, loose feel.
Why it matters: A sagging lining is not dangerous but is a visible, common defect that costs several hundred dollars to fix properly, so it is a fair bargaining point.
What to look for: Check the driver seat's outer bolster for cracks or flattened foam and the steering wheel rim for peeling.
Why it matters: A cracked bolster or peeling wheel is cheap to overlook but expensive to fix properly, and on an enthusiast car it knocks resale value more than the repair cost itself.
