Hyundai Sonata 2011–2014 · Pre-purchase checklist

Bring this to the inspection. Every check below is specific to this generation's documented failure modes, not generic used-car advice.

1. Check 01

   Run the VIN at a Hyundai dealer or on Hyundai's recall site: confirm the Theta II engine recall / KSDS knock-sensor software update was performed, and that the car is enrolled in the lifetime engine warranty from the settlement.

2. Check 02

   Cold-start the car and listen closely for a metallic knock or tapping, especially under light acceleration. That's the classic pre-seizure rod-bearing symptom. Walk away from any knock you can hear.

3. Check 03

   Check oil level and condition; ask for oil-change records. These GDI engines are unforgiving of low oil and stretched change intervals.

4. Check 04

   On 2011 cars, confirm the EPS (electric power steering) recall was done. Feel for sudden heaviness or an 'EPS' warning light while steering at low speed.

5. Check 05

   Turn the wheel lock-to-lock at a stop and listen for clicking/clunking from the steering column (the coupling/U-joint issue).

6. Check 06

   Inspect the panoramic sunroof (if equipped) for prior glass replacement or stress cracks; ask whether it has ever shattered.

7. Check 07

   On the 2.0T, look for oil-consumption signs and confirm it has been run on synthetic oil and good fuel.

8. Check 08

   Verify the brake-pedal-stopper / brake-light-switch recall was completed (brake lights staying on, or being able to shift out of Park without the brake).
