My Auto gearbox failed along with the torque converter whilst on holiday in Spain. The car was under warranty. KIA UK were involved after several weeks of email tennis with KIA Spain/KIA Assist.
The shocker was, KIA UK had no idea it was stuck out in Spain until i contacted them direct for help. 6 weeks later from breakdown. KIA UK Maaike was FANTASTIC
with her help in moving things forward. It still took another 6 weeks to get the problem sorted, however, with out her help it would still be there now 9 month on.
SO.....Moral is, if you breakdown abroad and its a serious fault, get it towed home.
