Credov's researched list of the 2 faults the Holden SS is known for (2006–2017), 2 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: Hold a steady 60-100 km/h on light throttle and feel for a fine shudder through the floor, like rumble strips.
Why it matters: The shudder is easy to mistake for a rough road or a misfire, and a persistent case needs a new torque converter, a significant transmission repair.
What to look for: Listen for an uneven idle, feel for a misfire under load, and watch for an ESP or check-engine light.
Why it matters: A car with some injectors replaced and some original is likely to need the rest soon, and a full set of eight is a sizeable bill on an otherwise sound engine.
