- Use an OBD-II scanner to check for any diagnostic trouble codes (DTCs) stored in the vehicle’s computer. This can provide valuable information about engine and transmission issues.
- Listen for unusual noises, especially knocking or pinging from the engine. Note when the noise occurs (e.g. during acceleration, at idle).
- Pay attention to any changes in performance, such as loss of power, hesitation, or rough idling.
- Check the oil level frequently and note if you need to add oil between scheduled oil changes.
- Test the Bluetooth connectivity with different devices to determine if the issue is consistent.
- Check the speakers by playing audio at different volumes and frequencies.
- Inspect the sunroof for any cracks or signs of stress.
- Monitor fuel consumption to detect any significant changes in efficiency.
- For transmission issues, note any slipping, jerking, or delayed engagement when shifting gears.
- Keep a log of when symptoms occur and under what driving conditions.
If you’re not comfortable performing these diagnostic steps yourself, it’s best to have a professional mechanic or Hyundai dealership inspect the vehicle. They have specialized tools and expertise to accurately diagnose these issues.
