Credov's researched list of the 2 faults the Nissan Skyline 300GT is known for, 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: At start-up check for a power steering or chassis warning, then confirm the wheel is centred and holds a line.
Why it matters: The first-generation system (2014-2016 builds) is worst; Infiniti revised the control logic from 2016. Repairs range from software and recalibration to steering modules or actuators costing several thousand dollars.
What to look for: Check for white or blue exhaust smoke on start-up and after idling, and feel for a sudden limp mode.
Why it matters: US complaints for 2017-2019 Q50s and Q60s with this engine are mostly at 70,000-230,000 km, some earlier, and Infiniti extended turbo warranty cover on US cars to 10 years / 120,000 miles. A pair of turbos costs about US$6,000-9,000; oil starvation from a failing turbo can take the engine with it.
