Build my inspection planKia Stinger · frequently asked questions
Is the Stinger reliable?
Yes, mechanically it is strong; abuse and missed gearbox services are the risks.
Does the Kia warranty help resale?
Very much · the seven-year transferable warranty is a genuine selling point on younger cars.
Which version sells best?
The GT-Line diesel for value buyers, the GT-S V6 for enthusiasts.
What should I check on a test drive?
Gearbox smoothness, brake feel and any vibration at motorway speed.
Are there specific servicing requirements for the 3.3 V6 spark plugs?
Yes, the 3.3 T-GDI engine requires spark plug replacement every 40,000 miles or 48 months. This is a labour-intensive job because the intake manifold must be removed to access the left bank. Ensure this is documented, as neglected plugs cause misfires under load and will significantly increase your preparation costs.
How can I tell if a Stinger has the factory limited-slip differential?
In the UK market, a mechanical limited-slip differential (LSD) was fitted as standard equipment to all 3.3 T-GDI GTS models. It was not available on the 2.0-litre petrol or 2.2-litre diesel variants. When retailing a GTS, always verify the differential casing for leaks during your ramp inspection.
