Hyundai I30 2014 Problems

It would seem that the problem with your car hasn't been fixed, and that instead of recommending you sell it, the dealer should be fixing it. Take it back and demand that the problem be sorted out, get Hyundai involved directly if you feel that will help resolve it faster.

The i30 definitely gets The Tick and should be fine for you.

When the Japanese brands slashed development spending through the global financial crisis, the Koreans spent more to improve their cabin quality, engines, gearboxes and everything else. Kia and Hyundai now also have specialist engineers who tune their suspensions just for Australia. They also lead on warranty and service costs, for a compelling overall package on cars like the Hyundai i30 and Kia Proceed.

Ask that a service representative go with you, so you can show them what the problem is and that it is still present. Once you have their agreement that there is a problem you should be able to move forward and get a resolution.

The replacement system should be one that's equivalent in age and condition to the old one, and in the case of one that is five weeks old I would expect the replacement to be new.
