      1. Hello I got problem for i20 middle 2010 the steering wheel is tight but it can turn and airbag ligh, handbrake and battery light is aappering what’s the problem

    1. Hi Patrick
      The first place to start is using scan equipment to access fault codes. The fault codes will help you drill down on where the problem is located. You can either purchase your own diagnostic tool or take your Hyundai to a vehicle workshop and use theirs.

    1. If it’s the only warning light that you have on, then essentially it’s a bit of a guessing game. When the engine light / MIL comes on, a fault code is generated (usually). diagnostic tool will read the fault codes and hopefully point you in the right direction of where the fault lies.
