I put my Dec 2015 i30 turbo auto in for its 15,000kms service. Returning to the dealer to pick it up I was told I would have to re book it in as there was a noise comming from the gearbox. I booked it back in and the gearbox was taken out and was supposeing fixed. At the 30,000 service I mentioned the noise was still there. The car was running ok except when idleing it would make a rattling noise.As soon as it went above idle the rattle would go. After noticing this I took it back to the dealer and the head machinic came out and I showed him the problem. He said it was only that it was a diesel motor making the rattle. The 45,000klms service I again mentioned the problem. It was booked in again to hopefully have the problem fixed. I received a phone call a couple of days before it was due to go in about a bulliten the dealer had received from Hyundai regarding the 7 speed turbo gearboxes. I was told they had to get special tools needed to carry out the repaires needed. I am still waiting for a reply more than three months ago. I will be booking the car in again in another week as I am going to Newcastle in it on the October long weekend and want the 60,000klms service carried out before I go. It has 58,700klms at present. I will call in on the way home from work tomorrow to book it in and to see what excuses they give regarding the repair. Please note I have done 45,000klms since waiting for the dealer to do the repairs. If they couldn't fix it back when it had 15,000klms on it than it is my opinion they don't know what to do. I work with a fellow who used th work with a transmission place and said that being a dual clutch automatic it would most possibly have to be replaced. I agree just put in a new gearbox. End of argument.
