Credov's researched list of the 2 faults the Holden Trailblazer is known for (2014–2016), 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: Pull the dipstick and check for low or very black oil, and look for blue-grey smoke on hard acceleration.
Why it matters: A heavy oil burner can run low between services and damage the engine, and some affected engines needed full replacement under warranty.
What to look for: Warm the car, hold 60-80 km/h on light throttle and feel for a vibration like rumble strips as the converter locks up.
Why it matters: Some cases have needed a full transmission replacement at very low kilometres, and parts delays have left owners without the vehicle for extended periods.
